TypeSafe AI has raised $870 million in a funding round that values the company at $7.5 billion, just weeks after the launch of its Jev model. Andreessen Horowitz led the round, with Sequoia and existing investor DCVC also participating.
Released on September 15, Jev is built on transformer architecture but differs from large language models: rather than generating text, it produces probabilities the company describes as "calibrated decisions." TypeSafe says the model is designed for task automation and can work faster while using fewer tokens than conventional language models.
The company also says about one-third of Fortune 500 businesses are already using Jev. TypeSafe was founded in 2024 by former OpenAI researcher Diogo Almeida, former Meta research engineer Sasha Sheng, and engineer and entrepreneur Erik Gafni.
Jev's rapid adoption points to growing interest in AI systems built to make operational decisions, potentially broadening automation beyond text and code generation.
