Sekai raises $20M Series A to enhance AI app creation platform

Sekai, a startup building what amounts to a TikTok-style feed of user-generated mini-apps, has closed a $20 million Series A round to expand its AI-powered creation platform. The company lets anyone, regardless of technical skill, build playable apps in seconds using nothing more than text prompts.

The round brings Sekai’s total funding to approximately $30 million, with backing from a roster of heavyweight venture firms including Khosla Ventures, Andreessen Horowitz (a16z), Mayfield, and A*.

Nearly a million apps in two months

Within two months of launching its AI-driven creation tools, Sekai’s platform hosted nearly 1 million mini-apps. Users generated roughly half a million apps per month, spanning games, utilities, and social tools.

The platform works through AI-powered coding agents that translate plain-language descriptions into functional, interactive applications. A user might type something like “make a quiz about 90s movies” or “build a split-the-bill calculator,” and Sekai’s system handles the rest.

Sekai also lets users remix, share, and engage with each other’s apps in a social feed format. The remix feature borrows from the playbook that made TikTok’s duets and sounds so viral, except instead of layering audio over video, users are forking and modifying interactive experiences.

The no-code revolution finds its consumer moment

No-code and low-code tools have been a recurring theme in enterprise software for years. Platforms like Bubble, Webflow, and Retool have carved out real businesses helping companies build internal tools and websites without hiring engineering teams. Sekai’s target user isn’t a product manager at a Fortune 500 company — it’s the same person who posts cooking videos on Instagram or creates memes in Canva.

Generative AI tools have expanded across creative categories: text (ChatGPT), images (Midjourney), video (Runway), and music (Suno). Interactive apps represent one of the last major creative categories where the barrier to entry has remained high. Sekai is positioning itself as the platform that collapses that barrier.

What this means for the tech landscape

One risk to watch: retention. Generating a million apps is impressive, but how many of those apps get used more than once? The gap between creation volume and sustained engagement has tripped up plenty of user-generated content platforms before.
