Tembo, headquartered in Cincinnati and accessible at tembo.io, is an AI developer teammate that allows any employee, technical or not, to assign software tasks through natural language prompts. The product creates pull requests in GitHub on behalf of the user, which a developer then reviews and merges, ensuring no code is pushed without human oversight. The company was founded in November 2022 by Ry Walker, who previously co-founded Astronomer, and completed a full pivot to its current AI agent model in May 2025. As of July 2025, Tembo operates on a pay-as-you-go credit model, with an average cost of roughly $5 to $10 per pull request. The company has attracted 2,000 sign-ups across approximately 200 organizations, converted 30 of those to paying customers, and recorded more than 1,000 merged pull requests since the pivot. Walker targets Fortune 50 enterprises as anchor customers, with a stated goal of $1 million per year contracts at that tier. Gross margins are currently negative, with Claude Code API costs exceeding 100 percent of revenue, a condition Walker describes as a pre-scale dynamic he expects to resolve as large customers bring their own API keys. Walker's North Star metric is merged pull requests, which he views as the end of the value chain and the clearest signal of customer retention and expansion potential.

Meilisearch is a RESTfull search API that is the ready-to-go solution for everyone wanting a powerful, fast, and relevant search experience for their end-users ⚡️🔎 Efficient search engines are often only accessible to companies with the financial means and resources necessary to develop a search solution adapted to their needs. The majority of other companies that do not have the means or do not realize that the lack of relevance of a search greatly impacts the pleasure of navigation on their application, end up with poor solutions that are more frustrating than effective, for both the developer and the user. That's why we created MeiliSearch, an open-source solution accessible to everyone, meeting the vast majority of needs, even specific ones. Installable very easily with little or no configuration required but with a high capacity for customization. Our solution is instant; it accepts typos; it understands filters, custom rankings, and a lot of other features.
