Base44: a bootstrapped vibe-coding builder that Wix bought for $80M after six months

Key takeaways

Wix bought the six-month-old, bootstrapped Base44 for about $80M in cash plus earn-outs through 2029, of which about $25M was set aside as retention bonuses for employees.
TechCrunch reported 250,000 users in six months and, citing the founder's posts, $189,000 in profit in May 2025.
Growth came mostly from word of mouth while the founder shared the build on LinkedIn and X. 'Solo' still meant a team of eight employees.

What it is

Base44 is a vibe-coding platform: you describe an app in plain language and it builds the whole thing, including database, storage, authentication and analytics (TechCrunch). Wix describes it as a chat-based interface that "manages technical details behind the scenes, from databases and authentication to deployment" (Wix press release).

Timeline

Launch: Shlomo called it "a moonshot experiment" on LinkedIn when it went public; it began as a side project (TechCrunch).
First three weeks: reportedly 10,000 users (TechCrunch).
May 2025: $189,000 in profit after LLM token costs, according to Shlomo's own posts as cited by TechCrunch (TechCrunch).
18 Jun 2025: Wix announced the acquisition for about $80M upfront plus earn-out payments through 2029 tied to performance (Wix press release). Wix confirmed to TechCrunch that the deal was cash; Base44 had reportedly grown to 250,000 users in its six months (TechCrunch).

What to learn

In an AI product, gross margin is a feature. Track token costs from day one, as Shlomo did publicly.
Sharing the build (numbers, model choices, mistakes) can be the whole distribution plan when you have no marketing budget.
A crowded category is not a "no". Base44 "isn't unique in this area" (TechCrunch), but it won on doing the whole stack for non-developers.
Know why you would sell. Shlomo said the "scale and volume we need is not something we can organically grow into" (TechCrunch).

Risks and what didn't work

"Solo" is a stretch: Base44 had eight employees, who share about $25M of the price as retention bonuses (TechCrunch, Wix press release).
User and profit figures are self-reported or "reported"; Wix itself expected the deal to make an "inconsequential contribution to 2025 bookings and revenue" (Wix press release).
Part of the price depends on earn-outs through 2029, so the final value is not fixed (Wix press release).
The founder's track record and network are hard to copy; this is not a typical first-time indie outcome.
