Folk became a representative modern CRM after its 2024 Series B. Clay (Kareem Amin) raised its Series B in 2024 and made AI-first contact enrichment the new standard for outbound. Dex and Monica hold the lightweight relationship-CRM lane, Salesforce / HubSpot / Pipedrive defend the enterprise classics, and Notion / Airtable have become a self-built-CRM alternative. This guide compares 17 tools on one page — Folk, Clay, Dex, Monica, Sortd, Streak, Attio, Less Annoying, Cloze, Capsule, Zoho, Insightly, Apollo, Lemlist, Outreach, Mixmax, Yesware, and Sansan — and separately covers the local context in Korea (KakaoTalk sync, Toss, Adsbi) and Japan (Sansan, freee, Money Forward). Who should pick what, and how the social GTM motion of 2026 shapes the CRM choice.

Folk는 2024년 시리즈 B 펀딩으로 모던 CRM의 대표가 되었고, Clay(Kareem Amin)는 2024년 시리즈 B와 AI-우선 컨택트 enrichment로 아웃바운드 영업의 새 표준을 만들었다. Dex와 Monica는 라이트한 관계 관리 노선을, Salesforce·HubSpot·Pipedrive는 엔터프라이즈 정통을 지키고, Notion·Airtable은 self-built CRM의 대안이 되었다. 이 글은 Folk·Clay·Dex·Monica·Sortd·Streak·Attio·Less Annoying·Cloze·Capsule·Zoho·Insightly·Apollo·Lemlist·Outreach·Mixmax·Yesware·Sansan까지 17개 도구를 한 페이지에서 비교하고, 한국(카카오 sync, 토스, Adsbi)·일본(Sansan, freee, Money Forward)의 로컬 컨택을 별도로 짚는다. 누가 무엇을 골라야 하는지, 그리고 2026년의 social GTM motion이 CRM 선택에 어떻게 영향을 주는지까지.
