TypeSafe closed roughly $870 million in new funding, valuing the company at $7.5 billion. Andreessen Horowitz led the round with the biggest check, joined by Sequoia Capital, DCVC, which invested early in the company, and a group of angels.
Andreessen Horowitz General Partner Martin Casado will take a seat on TypeSafe's board. The firm, which has backed OpenAI and xAI, also helps its portfolio companies secure computing resources by negotiating contracts and special pricing, according to a spokesperson. Before backing TypeSafe, the firm invested early and often in Cursor, which SpaceX bought this year in a $60 billion deal.
Jev is TypeSafe's first publicly available developer model, built by researchers with backgrounds at OpenAI, Meta and Google. It is not built to chat, draft emails or write code. Instead, it plugs into software to make decisions. Because it does not generate text token by token, the company says it can complete tasks faster and at lower cost than large language models.
The launch video for Jev spread widely only weeks ago. Co-founder and CEO Diogo Almeida said the buzz triggered a surge of inbound attention from fellow chief executives, developers, and investors. TypeSafe says Jev crossed one million users within days and that about one third of Fortune 500 companies now use it, though it declined to name customers.
Almeida, who founded TypeSafe in 2024, said the company has been a long time in the making. He wants to improve trust in AI by offering a dependable and affordable system, with more updates slated in the next several months. He also critiqued today's uneven model behavior: "If you get Einstein 95% of the time, but Mr. Bean the other 5% of the time, that is completely useless for automation."
TypeSafe runs on a lean team of just over 20 people in San Francisco and says it now processes trillions of tokens each day. To keep up with surging demand, the company leaned on Modal Labs, which helps other startups run AI models. Modal has drawn heavy investor interest and has discussed raising funds at around a $15 billion valuation, Bloomberg previously reported.
Consumer AI products are finally being valued on actual adoption. Market Briefs covers that market free every morning.
AI developers such as OpenAI, Meta and SpaceXAI are vying to deliver lower-cost systems as businesses look more closely at their AI budgets. The focus on affordability is intensifying as Chinese open-weight models push ahead and more companies adopt those options to reduce dependence on pricier services.
Casado likened TypeSafe's role to Cursor's impact on coding tools: Cursor made it easier to produce more software, while TypeSafe is helping developers build better software for less, he said. "There's almost like a Jev-shaped hole in the industry already," he added. "All the developers are like, this is what I've been trying to do - poorly."
TypeSafe plans to use the new capital to scale product rollouts, expand hiring and lock in more compute. Almeida said Jev is profitable after expenses, though the company declined to share revenue figures.
There is some startup flair here too. To celebrate early traction, the team agreed to dye their hair pink. With the team stretched by long hours to meet demand, Almeida instead broadcast himself dyeing his hair live to the TypeSafe community on Discord.
If TypeSafe delivers cheaper and faster automation at real scale, that can shift how a lot of software is built and what it costs. The next few months will be telling, with planned updates, more compute coming online and a small team trying to keep pace with big demand.
