Prologue — Why Solo SaaS in 2026

The phrase "one-person business" has floated around since the early internet. Someone said it was possible in 1999. When Pieter Levels built Nomad List in 2014, it sounded real for the first time. After COVID and the digital nomad boom of 2020, it got renewed attention. And in 2026, the phrase finally feels statistically normalized.

The reason is simple. The ceiling of what one person can build has risen far enough. Even in 2024, for one person to ship a six-figure-ARR SaaS, they had to grip design, frontend, backend, infrastructure, payments, customer support, SEO, email marketing, and tax — all at once. If their hands gave out, they had to hire. That broke between 2025 and 2026.

• Code generation — Cursor, Claude Code, and Junie reduced boilerplate to essentially zero. Last year's two-week task is now three days.
• Agentic operations — Slack bots, CS triage, SEO content pipelines, and invoicing now run through agents.
• Edge infrastructure — Free tiers on Cloudflare Workers and Vercel Edge can carry thousands of MAU. The first real bill arriving after 18 months is normal.
• Payment rails — Stripe + Lemon Squeezy + Polar made global payments, tax, VAT, and checkout into a delegable black box.
• Distribution — X (Twitter), Beehiiv, Substack, and YouTube put audience-building within reach without a media company.

This shifts the solo SaaS category from "one eccentric exception" to "a statistically reproducible pattern." Marie Martens' Tally runs at 5M ARR with a fully bootstrapped team of 11. Damon Chen's Testimonial.to stayed solo until reaching 1.3M ARR. Pieter Levels runs a roughly 250K USD/month portfolio with zero employees. This is no longer luck.

That does not mean everyone succeeds. About 90 percent fail. This article looks at how that 10 percent survived alongside where the 90 percent died. Eight cases, the 2026 standard stack, the audience-first vs build-first debate, the Korean indie maker scene, and a practical checklist.

Solo SaaS is no longer a game for the "lonely genius." It is a category with proven playbooks, a standard stack, and rich failure data. The core question in 2026 is not "is it possible?" but "are you prepared to be honest about it?"

All MRR/ARR numbers cited here come from public sources as of April-May 2026. Solo founder businesses move fast, so remember the timestamp.

1. The Economics of 2026 Solo SaaS

The point is not unit cost but asymmetry. A solo SaaS works only when three things align.

1.1 The cost curve is nearly flat

Traditional startups saw costs grow with ARR. Sales, marketing, CS, product, and infrastructure each consumed people at each stage. The 2026 solo SaaS is different. Cloudflare Workers, Vercel Edge, Supabase, and Stripe charge by usage, so a 10x ARR increase only doubles or triples infrastructure cost. Sales and CS get replaced by automation, agents, and self-serve checkout. The point is that you can push the hiring decision far down the road.

That is why Marie Martens runs Tally to 5M ARR with 11 people, and why Damon Chen pushed Testimonial.to to 400K ARR while still solo.

1.2 Distribution cost moved to time

Traditional SaaS distribution cost money — Facebook ads, Google ads, content marketers, conference booths. 2026 solo SaaS distributes on time. Building in public on X, Beehiiv newsletters, YouTube demos, and communities like Indie Hackers or Disquiet. You may have no money, but with a year of time you can build an audience.

The trap is symmetric. Time has no guaranteed return. Pieter Levels failed 12 products before Nomad List took off, and Damon Chen killed two products before Testimonial took off. You have to accept an 80 percent failure rate before starting.

1.3 One person's decision speed is a weapon

What a large company decides in a quarterly meeting, a solo founder decides in two hours. Raise prices? Cut a feature? Leave a market? The real solo edge is speed, not cost. AI tools in 2026 lowered the friction of code, design, and copywriting further, and that edge exploded.

The mathematical advantage of solo SaaS is this: the numerator (revenue) is the same as a normal SaaS, and the denominator (labor cost) is one. In a market where one person's salary is 200K USD, 1M ARR is an ordinary business but a fat-margin solo business.

2. Case Study 1 — Pieter Levels, the Canon of Solo SaaS

The canon of this category. Without Pieter Levels, none of the other cases in this article would exist. He built Nomad List in 2014, and over the 12 years since he has shipped and killed countless products.

Public numbers as of May 2026

• Photo AI — about 132-138K USD/month MRR (1.6M ARR)
• Remote OK — about 35-41K USD/month (around 2M ARR)
• Nomad List — about 38K USD/month (around 700K ARR)
• Interior AI — about 38-45K USD/month
• Portfolio total — about 250K USD/month, roughly 3M USD/year

Employees: zero. Location: anywhere. Year 12 of solo founding.

2.1 An honest look at the stack

What is interesting is that Pieter's stack looks "old-fashioned" by 2026 standards. He runs PHP + jQuery + a single VPS + SQLite. He uses Cursor and Claude Code, but the infrastructure is largely unchanged. A line he often repeats on X is: "New tech creates new bugs. I have been looking at the same bugs for five years."

What does this mean? In solo SaaS stack selection, the top criterion is "what do you know deeply?" Pieter knows PHP so well that switching to a new framework has no upside. A new solo founder should pick the stack where they are fastest, not chase Twitter trends.

2.2 Distribution — 12 years of build in public on X

Pieter's real weapon is not code but his X account. His 500K+ followers are the first audience for everything he builds. What he repeats every year is "build the audience before the product."

The catch: this took 12 years. Pieter's X has been active daily since 2014, and that compounding is the distribution channel he uses now. Expecting to be Pieter in six months is unrealistic. Starting with a smaller audience and compounding is the honest path.

2.3 What to copy and what not to copy

Copy:

• Build in public to compound an audience over time
• Use a product portfolio to spread risk (one death does not kill the business)
• Quick experiments, quick kills (12 failures are normal)

Do not copy:

• Mimicking his ship rate without 12 years of compounded audience
• Clinging to "I do everything alone" as an identity and refusing to outsource (Pieter himself outsources design)

3. Case Study 2 — Andrey Azimov, "Hardcore Year"

The first generation directly influenced by Pieter. In 2018, a Ukrainian developer declared a one-year challenge called the "Hardcore Year" and moved to Bali. Starting with 3K USD cash, the goal: be profitable within a year.

Products built:

• ProgressBarOSX (macOS menu bar progress indicator)
• Sheet2Site (turns a Google Sheet into a website)
• Dark Mode List
• PushToDeploy
• WhenToSurf

Result: From 1K USD/month average in 2018 to over 10K USD/month by 2020. Sheet2Site and Chart2Site were sold. Won Product Hunt's "Maker of the Year."

3.1 Core lesson — small, fast, many times

Andrey's approach is the opposite of Pieter's "one product for five years." Build five products in one year, bet on whichever survives. If it dies, sell it or move it to maintenance mode. This is another variant of the portfolio approach.

The appeal of this approach grows in 2026. Cursor and Claude Code shrink a one-week MVP to two or three days. Shipping 10 MVPs in a year and growing the one or two that get traction is statistically reasonable.

3.2 The trap

• Maintenance explosion — Five products you did not sell will overwhelm one person. That is why Andrey sold.
• Context switching — Running five products in parallel makes it hard to grow any one deeply.

4. Case Study 3 — Marie Martens (Tally), the Bootstrap Exemplar

Tally is a form builder started in 2020 by Marie Martens and Filip Minev. The positioning is crisp: "a Notion-style UI for forms."

As of April 2026

• Crossed 5M USD ARR
• 11 employees (still fully bootstrapped)
• Zero external investment
• 150K+ users

4.1 Not solo, but solo spirit

Marie and Filip are a couple. Strictly, this is not a one-person business but a two-person business at the start. Still, it belongs to the solo SaaS category — no VC, no sales team, no ads.

Tally's stack (as publicly disclosed):

• Next.js
• Tailwind CSS
• PostgreSQL (Supabase or Neon)
• Vercel
• Stripe
• Plausible Analytics

This is almost exactly the 2026 standard stack.

4.2 Core lesson — the free tier is a distribution channel

Tally's biggest decision was "put almost every feature into the free tier." Other form builders (Typeform, Jotform) locked critical features behind paywalls so users would churn out. Tally went the other way — free is good enough, with paid for teams, integrations, and advanced analytics.

Result: free users became the distribution channel. The forms they built scattered across the internet, generating SEO and word-of-mouth automatically.

4.3 What to copy

• A partner or small team to reduce founder loneliness — There is a statistic that 80 percent of solo founders die of loneliness. A small team lasts longer.
• The decision to use free as distribution — Not every SaaS is suited to freemium, but viral products like forms, quizzes, and notes are powerful in freemium.

5. Case Study 4 — Tony Dinh (TypingMind, BlackMagic), the Vietnamese Indie Maker

Tony Dinh is a Vietnamese developer. Between 2022 and 2023, he hit 14K USD/month MRR first with BlackMagic.so (a Twitter analytics tool), then sold it when Twitter changed API pricing. He then built TypingMind (a desktop client for ChatGPT).

Public numbers as of late 2024

• TypingMind: 45K USD/month MRR (B2C)
• With enterprise contracts factored in, hit 80K USD+ in a single month
• Margin: about 85 percent

Exact MRR for May 2026 is not public, but TypingMind remains an active product with continued model additions and feature expansion.

5.1 The honest reality of an LLM wrapper

TypingMind is "a better UI on top of ChatGPT." The category called LLM wrapper. Between 2023 and 2024, thousands of LLM wrappers were built and most died. TypingMind survived because:

1. BYOK (Bring Your Own Key) — Users plug in their own OpenAI/Anthropic API key. Tony does not pay API costs. That is why the margin is 85 percent.
2. Desktop native — A desktop app rather than a web client, so data stays local and is attractive to enterprise users.
3. Workspace and team features — Started as a simple chat client but expanded into prompt libraries, team workspaces, and MCP support, entering B2B territory.

5.2 Core lesson — even a wrapper survives if built honestly

"LLM wrappers are dead" is only half right. Generic ChatGPT clones are dead, but a wrapper deeply optimized for a specific user persona still lives. TypingMind is built precisely for the "technical power user" persona.

Honest advice for solo founders building an LLM wrapper in 2026: a generic chatbot builder is dead. Wrappers buried into a specific persona, domain, or workflow still live.

6. Case Study 5 — Damon Chen (Testimonial.to), the Canon of B2B Solo

Damon Chen is a US-based developer originally from China. Testimonial.to is "a tool to collect video and text testimonials from customers." Launched in 2021.

Public growth trajectory

• 9 months from launch: 100K USD ARR
• 17 months: 300K USD ARR
• Later crossed 800K USD ARR
• As of February 2026: about 840K USD ARR
• First hire at 400K ARR (marketing)

6.1 Core lesson — B2B distribution is SEO + build-in-public combined

Damon has two growth channels.

1. Build in public (Twitter/X) — 80-90 percent of early customers came from X. Damon shared daily build progress, revenue, and mistakes.
2. SEO and content — Content carefully crafted for keywords like "video testimonial software," "testimonial form," "social proof tool." It took 6-12 months but compounded.

This pairing is the canon of solo B2B SaaS. X delivers short-cycle, experimental, high-quality audience. SEO delivers long-cycle, compounding, purchase-intent audience. Neither costs money (only time).

6.2 The solo limit and the timing of the first hire

Damon made his first hire at 400K ARR — marketing. Until then, fully solo. This pattern — first hire after revenue stabilizes — is the statistical pattern of solo SaaS.

Hiring too early drains cash; hiring too late burns out the founder. From Damon's case there is a rule of thumb: 400-500K ARR is roughly "the solo limit." Not exact, but a useful reference.

7. Case Study 6 — Arvid Kahl (FeedbackPanda → Creator), Pivoting After Exit

Arvid Kahl is a German developer. With his partner Danielle Simpson, he built FeedbackPanda (a SaaS for online English teachers).

History

• Started 2017
• Hit 55K USD/month MRR in two years
• Sold to SureSwift Capital in 2019 (seven-figure USD, exact amount undisclosed)
• Staff: just the two of them until the end

After the exit Arvid pivoted to "creator." Books (The Embedded Entrepreneur, Zero to Sold), a podcast (The Bootstrapped Founder), a newsletter, and a new SaaS called Podscan.fm.

7.1 Core lesson — the second chapter of a solo founder

Arvid's case shows the pattern after a solo SaaS exit. He sold for millions, yet he works again — this time as a creator. A line he often says: "The exit money is not cash flow for the next business. It is the guarantee of freedom."

One of Arvid's most interesting essays in spring 2026 is about the risks of build-in-public. In an era where AI agent tools can rapidly clone everything from public details, sharing too much invites a precise clone. The point is fair.

7.2 The new rule of build-in-public

Arvid's proposed 2026 rule:

• Share high-level insights — "this market has these people," "this channel worked"
• Keep low-level details private — exact copy, ad targeting, price experiments, the roadmap
• Use public tools (like Podscan) to monitor clones — track whether someone is copying you

8. Case Study 7 — Pat Walls (Starter Story), Evolution into a Media Company

Pat Walls is American. Starter Story is a media brand built on "interviews with successful solo and small-team founders." Started in 2017.

History

• 1.4-1.6M monthly visitors
• About 1.1M USD/year revenue
• Acquired by HubSpot in February 2026 (exact amount undisclosed, only "seven-figure")
• Acquired alongside: The Hustle, My First Million

8.1 Core lesson — content businesses are also one-person businesses

Strictly, Starter Story is not SaaS — it is a media and content business. But the same pattern applies — one person starts, SEO and content distribute, monetization through ads, subscriptions, and courses.

In 2026 content businesses are under AI-era pressure. As ChatGPT becomes the first source for all information, search traffic is dropping. Despite that, Pat's model survives because:

1. AI cannot fake interviews — Real founders' exact data, mistakes, and decisions cannot be hallucinated by an LLM.
2. Community lock-in — Starter Story is not just a content site but runs a paid community. Members do not leave.
3. Acquirable asset — 1.4M monthly visitors is an asset directly sellable to advertisers or to a media company.

8.2 Not SaaS, but a model of solo business

While other cases in this article are SaaS, Pat's is content. The solo path is not only SaaS. Content media, newsletters, education (Beehiiv, Maven), marketplaces, and digital products are all solo business categories.

The 2026 solo business landscape can be cleanly split into five categories: 1. SaaS, 2. content media, 3. digital products and courses, 4. consulting / DFY (Done For You), 5. information marketplaces. Which one fits depends on your strengths, audience, and market size.

9. Comparison Matrix — All Cases at a Glance

The pattern shows up directly:

• Portfolio vs single product — Pieter and Andrey run portfolios. Marie and Damon concentrate on a single product.
• B2C vs B2B — B2C distributes via X and virality. B2B distributes via SEO, content, and sales.
• Common channel — Almost all of them seeded their audience on X (Twitter). The single-channel weight is overwhelming.

10. The 2026 Standard Stack, Dissected

Now to tools. If a solo founder starts a SaaS as of May 2026, the standard stack looks like this.

10.1 Code — Cursor + Claude Code + Junie (set)

The most common combo for one developer in 2026:

• Cursor — chat, autocomplete, and code transforms inside the IDE
• Claude Code — an autonomous agent running in the terminal. Multi-file work, refactors, test runs
• Junie CLI / Codex CLI — long-running background jobs (an hour-plus migration etc.)

Running all three is common for a solo founder. Cost is roughly 100-300 USD/month (depending on model usage).

10.2 Backend — Bun + Hono (or Node + Hono)

Bun has become the default for solo founders in 2026. Fast, native TypeScript, npm/node compatible, with the package manager built in. Hono sits on top — lightweight (14KB), multi-runtime, running on Cloudflare Workers, Bun, Deno, or Node.

Express was the standard for a decade, but for new projects in 2026 Hono is effectively the default. Express has no multi-runtime support and no TypeScript-first design.

Alternatives: Elysia (Bun-only, faster but not multi-runtime), Next.js API Routes (when going full-stack-monolith).

10.3 Frontend — Next.js (or Astro, SvelteKit)

Next.js remains the default, but SEO-centric sites often pick Astro. Tally uses Next.js because dashboard and app surfaces are the SaaS core. Content-centric sites (like Starter Story) lean lighter on Astro/SvelteKit.

10.4 Database — Postgres (Supabase / Neon)

The default DB for solo founders in 2026 is Postgres, hosted on Supabase or Neon. Supabase bundles Postgres + Auth + Storage + Realtime in one box. Neon is lighter with strong branching (dev forks).

Some founders, like Pieter, still ship with SQLite. That works for them. For a fresh solo founder, Postgres on a managed host is safer.

10.5 Infrastructure — Vercel (or Cloudflare Workers + Pages)

Vercel is the default for Next.js. The free tier carries thousands of MAU. As traffic grows, many solo founders move to Cloudflare Workers (bandwidth cost there is overwhelmingly cheaper).

Pieter still runs everything on a single VPS. It works. Still, a fresh solo founder is best served starting on a free tier and migrating when traffic grows.

10.6 Payments — Stripe (or Lemon Squeezy, Polar)

Stripe is the global default. The pain point for solo founders is tax. European VAT, US state-by-state, Japanese consumption tax, Korean VAT — handle it yourself and accounting explodes.

The fix: Lemon Squeezy (now acquired by Stripe), Polar, and Paddle are "Merchant of Record" services. They handle payment, tax, and refunds on your behalf, and you receive one receipt. Fees are higher (5-8 percent vs Stripe's 2.9 percent), but tax friction disappears.

10.7 Audience — Beehiiv (newsletter) + X (Twitter) + YouTube

The audience stack:

• X (Twitter) — fast real-time audience. Downside: algorithm dependence.
• Beehiiv or Substack — an email list. Algorithm-independent.
• YouTube — long-term SEO asset. High content cost but strong compounding.

The most common solo founder pattern: start on X to assemble an audience, migrate them to email, and slowly compound deep content on YouTube.

10.8 Operations — agentic

What lets a 2026 one-person business stay one person is operational automation. A representative stack:

• CS triage — Intercom + LLM agent for first-pass response, humans only for complex cases
• Slack bot — real-time alerts for revenue, signups, refunds
• Content pipeline — Claude/GPT drafts → human edits → publish on Beehiiv
• Payment and invoicing — Stripe + Polar handle it
• Tax records — SaaS like Bench or Pilot auto-records

All of this concentrates the solo founder's time on "more user acquisition."

11. Audience-first vs Build-first — An Honest Conclusion

A debate that recurs every year in the solo SaaS community. Build an audience first then sell a product to it, or build a product first then find an audience?

11.1 The audience-first case

Notable proponents: Arvid Kahl, Daniel Vassallo, Justin Welsh.

Logic: with an audience, 1000 people see your launch day. Without, zero. With an audience you know the real problems (you talk to them daily). Without, you guess.

Evidence: Pieter Levels' 500K X followers are the initial thrust of every launch. 80-90 percent of Damon Chen's early customers came from X.

11.2 The build-first case

Notable proponents: Pieter Levels (early days), Tony Dinh.

Logic: while you spend a year building an audience, the market shifts. Ship a product fast to validate "do people need this?" The audience follows the result.

Evidence: When Tony Dinh built BlackMagic he had no large audience. He built his X audience after BlackMagic's success.

11.3 The honest conclusion — both are right, just in time order

The pattern I have seen: before the first launch, build a small audience of 100-500 people. Not a year-long mass audience, but 100 real people who share your problem. They are the candidate pool for your first 50 customers.

Then launch the product and grow the audience from users. User interviews, build in public, content. Audience-building after launch is faster — real users exist.

This is neither audience-first nor build-first. It is "small audience → product → larger audience" in a loop. Almost every success case follows this shape.

Launching with zero audience kills you. Hanging on to audience-building forever also kills you. Launch with a 100-500 person audience to get real feedback, then grow the audience with that feedback. That is the honest path in 2026.

12. The Real Reasons 90 Percent Fail

Every case in this article is a surviving 10 percent. To be honest, you also have to look at the dead 90 percent. The seven most common failure patterns in the solo SaaS market.

12.1 The market is too small

The most common failure. Building a product from "this tool would be nice" said by five friends, only to find the entire market has 100 potential customers. Solo SaaS still needs a real market. A reasonable lower bound is 50K+ global potential customers, 5 percent conversion = 2500 customers, ARPU 30 USD/month = 75K MRR.

12.2 Distribution depends on one channel

Lean entirely on X, or SEO, or Product Hunt, and a channel shift can erase 30-70 percent of revenue. Pieter himself went through stretches where X algorithm changes cut his reach. Two to three independent channels is the safety line.

12.3 Pricing is too low

The mistake solo founders make most. Start at 9 USD/month, collect 100 users, you have 900 USD/month. A regular job pays better. An honest solo SaaS starts at ARPU 30-100 USD/month, and B2B commonly 100-500 USD/month. Lowering price is easy; raising it is hard.

12.4 You are not the user

If you do not use the product daily, you cannot know what real users want. Pieter was a nomad and built Nomad List. Damon needed testimonials for his own marketing and built Testimonial.to. Marie was frustrated with form builders and built Tally. The pattern of your own itch → real product is not a coincidence.

12.5 Time-bound challenges with too little runway

Challenges like "be profitable in one year" are good. But the statistical reality of solo SaaS is 18-24 months to profitability. Damon hit 100K ARR in nine months, but that is top 5 percent, not the average. Do not kill the product because you did not break even in a year.

12.6 Loneliness and burnout

A statistic says 80 percent of solo founders quit within 12 months due to loneliness and burnout. No coworker, every Sunday feels like Monday, vacation feels like leaving your company undefended.

Mitigation:

• A small community of fellow solo founders (Indie Hackers, MicroConf, Disquiet)
• Force a complete day off once a week
• A real vacation every six months (most solo founders skip this, but they must not)

12.7 Ignoring accounting and tax

The scariest trap. Once your solo SaaS crosses six-figure ARR, tax exposure explodes. Global payments mean VAT, US state taxes, Korean VAT, comprehensive income tax, social insurance, corporate vs sole proprietor. Engaging an accountant from the start is safer. A monthly cost of 200-400 USD now prevents a 10K USD penalty a year later.

13. The Korean Indie Maker Scene

Korea's solo SaaS scene has a different shape from the global mainstream.

13.1 Disquiet — the maker community

Disquiet is a Korean maker community started in 2020 by Hyunsol Park and Jenny Hong. A Korean Product Hunt + maker SNS. As of 2026, it is the most active gathering place for Korean indie makers.

Common patterns on Disquiet:

• SaaS started as a side project
• Products scratching the founder's own itch (productivity, time management, learning)
• B2C heavy (Korean B2B SaaS has high entry barriers)

13.2 Structural difficulties for Korean solo SaaS

Compared to global solo founders, the friction in the Korean market:

1. Payment and tax friction — Korean payments rely on PG companies (Inicis, KCP), and VAT and comprehensive income tax processing is complex. Launching with global Stripe alone makes paying impossible for Korean users.
2. Market size — Korean single-market is roughly 50 million people. About 1/30 of the global English market. ARPU is usually lower.
3. No language leverage — The global English market unifies US, EU, India, and more. The Korean-only market reaches only Koreans.

13.3 Reasonable strategies for Korean solo SaaS

Due to these structural constraints, Korean solo founders commonly take one of two paths.

Strategy A — Monopolize a Korea-specific niche

A product anchored in Korean language, culture, or regulation. Real estate, Korean accounting, military, Korean-style payments, Korean academies. Global SaaS has trouble entering these areas — there is a moat.

Examples: zoomers paid for Korean academy management SaaS, niche Korean real estate listing tools, Korea-specific accounting helpers. The market is small but only Korean makers can enter.

Strategy B — Global from day one

Ignore the Korean market. English site from the start, global Stripe, X and Product Hunt distribution. Tony Dinh's Vietnam model.

Examples: TaskAde (founded by Korean John Xie, a global collaboration tool). Korean users are likely under 5 percent. Targeted at the English-speaking world from day one.

The middle ground — "start in Korea, go global" — is possible but hard. Translating a Korean product into English requires redesigning messaging, features, and cultural assumptions.

13.4 Common failures of Korean solo founders

• Postponing the corporation vs sole proprietorship decision — Once revenue exceeds 100M KRW, incorporation often becomes advantageous. Do not delay consulting an accountant.
• Ignoring VAT — Receiving only global payments while reporting revenue without collecting Korean VAT is a tax bomb.
• Health insurance and national pension — A solo entrepreneur is on the hook for the four social insurances. Premiums rise with revenue.

The real differentiating variable for a Korean solo SaaS is not tech but how fast you handle the tax, legal, and payment friction. Schedule a session with an accountant and tax advisor within the first three months. That prevents the death that arrives two years later.

Epilogue — The Pre-Launch Checklist for One-Person SaaS

A blunt checklist distilled from every case in this article.

Pre-start checklist

[ ] Is this a product you will use daily? (user = you)
[ ] Are there 50K+ global potential customers? (market sizing)
[ ] Do you have 6-18 months of cash runway? (the real time horizon)
[ ] Do you have 100+ real audience on X or LinkedIn?
[ ] Are you willing to work daily for 24 months?
[ ] Do you have safeguards for loneliness and burnout? (community, friends, rest)
[ ] Have you booked a first call with an accountant or tax advisor?
[ ] Can you start pricing at 30 USD/month or higher?

First-90-day action plan

Days 1-30:
  - Interview five potential users (verify the real problem)
  - Design the MVP
  - Register a domain and a landing page (collect emails via Beehiiv/Substack)
  - Begin daily build-in-public on X/LinkedIn

Days 31-60:
  - Start coding the MVP (Cursor + Claude Code + Next.js + Stripe)
  - Target an early audience of 100 (email list)
  - Recruit 10 beta users

Days 61-90:
  - Paid launch (price 50-100 USD/month)
  - Get the first 10 paying users
  - 1:1 calls with every user
  - Analyze first-quarter revenue, refund, and churn patterns

Anti-patterns to avoid

- Relying 100 percent on one distribution channel (X or SEO)
- Overly generous free tier (most solo SaaS is not freemium-shaped)
- Building a product you do not use yourself
- Hiring before revenue stabilizes (stay solo until at least 400K ARR)
- Outsourcing core tech and not understanding it
- Unrealistic goals like "1 million dollars this year"
- Postponing tax and legal (bomb in 6 months)
- Chasing every new tech trend (Pieter runs 3M ARR on PHP)
- Killing the product because there is no revenue at month 6 (18-24 months is normal)
- Launching with no audience and asking "why is no one buying?"

The next post is "What did one person do over 36 months?" — a detailed look at the daily time breakdown for one of these case studies. Coding hours, marketing hours, CS hours, downtime. The real day-to-day of a one-person business.

After that comes the solo founder in the age of AI — once agents automate 70 percent of operations, what should the human do with the remaining 30 percent? An honest guess at the shape of solo SaaS in 2027.
