EliseAI has raised $350 million at a $4 billion valuation in a round co-led by Andreessen Horowitz and Bessemer Venture Partners. Ontario Teachers’ Pension Plan, Sapphire Ventures and Navitas Capital participated. The funding marks the fourth investment by Andreessen Horowitz and Bessemer in EliseAI since 2023 and follows the company’s $250 million Series E by about 13 months. EliseAI said the valuation is double that of its Series E last August, while earlier reporting associated that round with a $2.2 billion valuation. Founded in 2017 by CEO Minna Song and CTO Tony Stoyanov, EliseAI builds AI software that automates administrative work for multifamily housing and healthcare providers. Its housing platform serves roughly one in six U.S. apartments, and the company said this summer that it had surpassed $200 million in annual recurring revenue. EliseAI recently introduced Apollo, an AI teammate integrated into its platform to support work across leasing, maintenance and renewals. The company plans to use the funding to expand engineering, deployment and sales teams and establish San Francisco as a second engineering hub alongside its New York headquarters.
