What Whattime does

Whattime (Whattime Co., Ltd. / 주식회사 왓타임) is a Seoul-based SaaS company founded in 2021 that operates Doen Time (되는시간), a Korean-market online business scheduling and calendar-coordination platform. The product enables individuals and teams to publish reservation pages, synchronize availability in real time across Google, Microsoft Outlook, Apple iCloud, Naver Calendar, and Naver Works, and auto-generate Zoom or Google Meet links upon confirmation. It supports 1:1 bookings, group meetings, co-hosted sessions, and round-robin host rotation, plus inline/widget website embedding for OEM-style use.

The platform is delivered as cloud-hosted SaaS with an underlying booking API and webhook callbacks available to Enterprise customers. Whattime sells on a tiered subscription: Basic at ₩10,000 per user per month, Pro at ₩12,500 per user per month (adding KakaoTalk SMS, Slack, team pages, Zapier, and Gmail workflows), and a custom-priced Enterprise tier that unlocks API access, dedicated account management, and onboarding services. A 7-day free trial and Google/Microsoft SSO power a self-serve SMB motion, while a direct-inquiry enterprise motion covers larger accounts.

The company was seeded in May 2022 by Wanted Lab (원티드랩) and The Ventures (더벤처스), received TIPS Program backing in October 2022, and grew to 1–10 employees serving 50+ customers including Samsung, LG Uplus, Hanwha, CJ, Hyundai Motor, Kakao Bank, Toss Securities, NCSoft, Naver Cloud, and multiple universities. On July 1, 2026, Whattime is being absorbed into CodeIt (주식회사 코드잇) via a simplified merger under Korean Commercial Code Article 527-2 at a 1:0 ratio, with CodeIt as the surviving entity.
