Weavel

Weavel began as a tool for automating prompt engineering. The premise was that writing and iterating on prompts by hand is slow, version-prone, and hard to reproduce, so Weavel aimed to generate optimized prompts automatically and improve accuracy for teams building on large language models. That made it relevant to anyone shipping LLM features, from solo developers to product teams running experiments.

The company is part of the Y Combinator S24 batch and is based in San Francisco. Its site currently describes a shift in focus: the team states it is building Typa, a storytelling platform for modern companies, and points visitors to that product. This is a common pattern for early-stage startups, where the founding team pivots from an initial idea to a refined product thesis while keeping the corporate identity in place.

If you arrive looking for the original prompt-optimization tooling, the safest reading is that Weavel's current public focus is the Typa storytelling platform. Pricing is not published, and the company directs interested parties to get in touch rather than listing plans, which fits its enterprise-oriented, contact-for-pricing approach.
