What if creating software felt less like coding and more like posting to Instagram?
That's the gamble behind Sekai, a Sunnyvale startup that closed a $20 million Series A round on the premise that mini-app creation—powered by AI and stripped of technical barriers—could become the next social media primitive. The funding, announced June 1, 2026, was co-led by Khosla Ventures and Connect Ventures, the joint venture between Creative Artists Agency and New Enterprise Associates. Joining them: a16z Speedrun, Mayfield, A*, MVP Ventures, 359 Capital, Parable VC, and 645 Ventures.
It's a crowded cap table for a company barely 18 months old. Sekai has now raised $29 million since launching with a $3 million pre-seed in September 2024, followed by a $6 million seed round led by Mayfield the next year.
The pitch is deceptively simple. Open the app. Type what you want—a personality quiz, a countdown timer, an interactive card. Seconds later, you've got a working mini-app, what Sekai calls a "Sekai." Share it. Watch others remix your creation. Repeat.
"Software as a New Media," the company calls it, though CEO Lucky Zhang and cofounder Arthur Cheung might just as easily describe it as TikTok for functional toys. Cheung would know something about that—he was a founding member of TikTok and ran the company's India operations before it became a geopolitical flashpoint, according to a16z Speedrun's portfolio page.
The Numbers That Turned Heads
Sekai's early metrics suggest people are actually building, not just scrolling. The platform claims more than 15 million mini-apps created to date, with roughly 200,000 new ones materializing daily, according to company data shared with Axios. The average user spends over an hour per day on the platform—a retention figure that, if accurate, rivals entrenched social networks. Google Play lists more than 1 million installs.
That's a steep climb from earlier this year when Sekai's marketing materials referenced around 1 million total apps. Whether the growth is organic or algorithmically goosed remains an open question, one investors apparently felt comfortable enough to overlook.
The interface itself leans heavily on discovery. Users scroll through a feed of mini-apps—some polished, many charmingly janky—and can remix anything they encounter. There's a web gallery for desktop browsers, but the action lives on mobile.
What's Being Built
Spend ten minutes browsing Sekai and you'll find interactive birthday cards, choose-your-own-adventure stories, calorie calculators, meme generators. Some apps feel genuinely useful. Others are pure whimsy, the digital equivalent of doodling in a notebook margin. The variance is part of the appeal, perhaps—permission to ship half-baked ideas without the weight of "real" software development.
It also raises the familiar challenge of user-generated platforms: how do you curate quality without killing creativity? Sekai hasn't publicly detailed its moderation approach, though the company says creator monetization is coming soon.
That's where Connect Ventures enters the picture. Leveraging CAA's Rolodex, the firm is working with Sekai on creator and celebrity partnerships—a familiar playbook borrowed from every social platform that's tried to bootstrap legitimacy with boldfaced names. Whether a Kardashian-coded quiz app moves the needle for Sekai remains to be seen.
The Bigger Bet
Underneath the funding announcement is a question Silicon Valley has been circling for years: can AI democratize software creation enough to make it a casual activity? Previous generations of no-code tools captured enterprise budgets but never quite cracked mainstream behavior. Sekai's wager is that consumer social dynamics—feeds, remixing, viral loops—might succeed where utilitarian platforms stumbled.
Zhang's background is in consumer social apps, though the company has been tight-lipped about specifics. LinkedIn pegs Sekai's headcount between 11 and 50 employees, a deliberately vague range that suggests the team is still lean. That's both a feature and a risk. Small teams move fast. They also break under scale.
The funding gives Sekai runway to find out which scenario unfolds. Whether people will keep generating 200,000 mini-apps a day six months from now—or whether the novelty fades like so many AI-powered experiments before it—is the sort of uncertainty that makes venture capital simultaneously thrilling and punishing.
For now, at least, Sekai has believers. And a cap table deep enough to chase the answer.
