AI21 Labs
The Tel Aviv lab founded in 2017 by the Stanford AI professor Yoav Shoham, the entrepreneur Ori Goshen and the Mobileye founder Amnon Shashua. It was one of the first companies outside the US big labs to train and sell a GPT-3-scale language model (Jurassic-1, August 2021), and it ran a popular consumer writing assistant (Wordtune, October 2020). It became a unicorn with a $208m Series C at a $1.4bn valuation backed by Google and Nvidia (August–November 2023), and released an unusual hybrid open model family, Jamba (March 2024). It then failed to raise a frontier-scale round, stopped developing Wordtune (April 2025), had a $300m round with Nvidia and Google fall through and denied reported Nvidia acquisition talks (December 2025–January 2026). Talks with Nebius ended in a licensing partnership rather than a sale, and in May 2026 it cut ~110 of ~180 staff and stopped developing Jamba to focus on its Maestro agent platform (reported). It is the clearest case in this knowledge base of a capable second-tier model lab squeezed out of the model business.
