Base44 Launches In-House LLM to Power Vibe Coding
Base44, the vibe-coding platform acquired by Wix a year ago, has begun rolling out its own custom large language model, Base1, to help users create apps via natural language. The company says Base1 was trained on a dataset generated from "tens of millions of real user interactions" on its platform. Base44's founder, Maor Shlomo, argues owning the model lets the company optimize latency, cost and efficiency as startups seek defensibility by leveraging proprietary data, distribution and infrastructure. The move comes amid competition from both specialist startups (e.g., Lovable) and frontier AI labs (Cursor, xAI/SpaceX, Anthropic). Base44 says it has passed $100M ARR; its parent Wix recently announced workforce reductions while Base44 has grown headcount since acquisition.
A startup building a proprietary LLM signals a wider trend of applied-AI companies pursuing defensibility through owned models and data; impacts cost, latency and margin economics for AI-enabled developer platforms, but the change is incremental rather than industry-shifting.

Wix Buys LLM Web-builder Base44 for $80M
Maor Shlomo sold Base44, a six‑month-old no‑code web-app generator powered by large language models, to Wix in June 2025 for $80 million in cash plus earn-outs through 2029. Base44 scaled rapidly—reportedly reaching $1M ARR within weeks, hundreds of thousands of users, and posting $189,000 profit in May 2025—while facing high model-inference costs that comprised roughly 89% of spend. To control costs he moved model inference across providers (AWS Bedrock, Google Vertex, Anthropic) and relied on tools such as Cursor and Claude. Wix confirmed Base44 had eight employees at sale and allocated $25M as a retention pool; additional milestone payments could add up to another $90M for Shlomo. The deal highlights fast-paced LLM productization, steep operational costs for inference, and active M&A appetite for AI-driven tooling.
Base44 Launches Base Code, Helping Teams Collaborate and Ship Faster

This is the latest in a series of product launches and updates from Wix and its subsidiaries, including the integration of native Google Ads campaign management and the launch of Symphony by Wix.
Vibe‑Coding Makes In‑house SaaS Viable
The article examines how AI-powered development environments — termed “vibe‑coding” for software built via natural language — are lowering technical and cost barriers to creating bespoke tools. Collins Dictionary named “vibe‑coding” Word of the Year 2025, and Bitkom data cited in the piece says roughly one in three German companies now use AI. It follows a t3n PRO Use Case with Berlin consultancy Dayone, which traced a path from a designer’s spare‑time sourdough app to a documented decision framework that models when in‑house builds beat buying SaaS licenses. The article argues that if AI substantially reduces development effort, traditional buy‑vs‑build economics for some SaaS products could be undermined.
