Vibe coding has mostly lived inside developer tools such as Cursor, Claude Code and Replit. Sekai wants to move that habit onto consumer phones: describe an idea, get a playable mini app, open it immediately, remix other peoples creations and keep browsing.
The company has raised a $20 million Series A led by Khosla Ventures and Connect Ventures, with a long list of investors including a16z Speedrun, Mayfield, A*, MVP Ventures, 59 Capital, Parable VC and 45 Ventures. It previously raised a $6 million seed round in 2025 led by Mayfield.
The usage numbers are the headline. Sekai says users have created 15 million mini apps, add about 200,000 more every day, and spend more than one hour a day on iOS and Android. Connect Ventures co-founder Nicole Quinn said that depth of daily use was the kind of product obsession signal the firm looks for.
Sekai is not positioning itself as a programmer productivity tool. It looks more like a social feed where the unit of content is software rather than video. Founder Lucky Zhang, who previously sold Yi+ AI to Apple and Blacktail to ByteDance, is betting AI-generated software can become a mass consumer format. The open question is retention: how many of those mini apps are opened again after the novelty fades.
