What is Base1 and who trained it?

Base1 is Base44's custom large language model, developed and trained on a dataset generated from tens of millions of real user interactions on the platform.

How much revenue does Base44 generate?

Base44 has passed $100 million（約160億円） in annual recurring revenue. By comparison, competitor Lovable reached $500 million（約800億円） in ARR.

Why is Base44 building its own model instead of using existing ones?

According to founder Maor Shlomo, training and owning the model allows more optimization on latency, cost, and efficiency. The company aims to offer customers a faster and cheaper alternative to frontier models like Opus, while also aligning the model more closely with what users prefer.

Base44 launches homegrown AI model as startups defend turf

TechCrunch AI3h ago5 min read

Key takeaway

Base44, a no-code app platform acquired by Wix for $80 million（約130億円） last year, has launched its own AI model to reduce dependence on external frontier models and cut costs for customers. The move reflects a broader industry concern: whether businesses built on top of someone else's models can stay defensible long-term. Base44 is betting that owning its data, infrastructure, and model will give it an edge over competitors relying on external models — though it now faces rivals that include major frontier AI labs entering the space.

3 Key Points

What happened
Base44, a no-code app-building platform acquired by Wix for $80 million（約130億円） a year ago, has begun rolling out its own large language model called Base1, trained on tens of millions of real user interactions on the platform.
Why it matters
AI startups are increasingly asking whether they can survive long-term by relying on external frontier models. Base44's move reflects broader pressure on businesses to control their own data, infrastructure, and costs. Building a custom model allows the company to optimize for latency, cost, and efficiency — and potentially offer cheaper service to customers than using frontier models like Opus.
What to watch
Base44 has passed $100 million（約160億円） in annual recurring revenue, though competitor Lovable (which relies on external models) has reached $500 million（約800億円） in ARR. The company faces emerging competition not just from other no-code startups but from frontier labs themselves — Cursor (owned by SpaceX), xAI's Grok, and Anthropic's Claude Code are all moving into the vibe-coding space.
