About Us

AI21 Labs is a first mover generative AI company co-founded by AI luminaries and serial entrepreneurs Prof. Amnon Shashua (Hebrew U, Mobileye), Prof. Yoav Shoham (Stanford, Google), and Ori Goshen (8200, Crowdx) with the mission to empower businesses with state-of-the-art LLMs and AI applications.

Knowing that no single LLM can be the best at all tasks, AI21 has developed new types of hyper focused language models that each excel at a specific capability. In November 2023 AI21 Labs closed an oversubscribed Series C funding of $208 million at a valuation of $1.4 billion, which included investments from Google, Nvidia, Intel Capital, and Comcast Ventures. AI21 was among the first companies to bring generative AI to the masses and in addition to its enterprise solutions it also offers a popular application - Wordtune, used by millions of professionals.
