AI tools that died in 2023

Rephrase.ai was the generative AI synthetic video platform founded in 2019 in Bangalore by Ashray Malhotra, Nisheeth Lahoti, and Shivam Mangla. The company created personalized synthetic videos with AI-generated avatars and voice, used by Cadbury, Prudential, and Pepsi for marketing campaigns. Adobe acquired Rephrase.ai in December 2023 to bolster the Firefly Video roadmap, part of Adobe's pattern of buying generative AI to defend its creative franchise against Runway and Pika. The standalone product was sunset; team and tech were folded into Adobe Firefly Video.

Olive AI was the healthcare automation startup that hit a $4B valuation in mid-2021 — the highest-valued healthcare AI company at peak hype. Founded by Sean Lane in 2012 in Columbus, Olive offered RPA-based automation for hospital revenue cycle work. Aggressive M&A expanded surface area faster than the tech could deliver. By 2022 customers complained 'Olive AI' was RPA marketing rather than real AI. The company sold core revenue-cycle assets to Waystar and Humata Health in October 2023 and wound down. Olive became the canonical example of the 2023 healthcare AI valuation reset.

Embark Trucks was the autonomous trucking company that went public via SPAC in November 2021 at ~$5B valuation, founded in 2016 by Alex Rodrigues and Brandon Moak (both Thiel Fellows). The company targeted Level 4 trucking on US interstates and ran a test fleet Houston-to-El Paso. Despite the SPAC valuation, Embark never generated meaningful revenue and laid off 70% of staff in late 2022. By March 2023 it wound down entirely. Remaining IP was sold to Applied Intuition. Embark became a flagship example of SPAC AV companies whose tech never reached commercial deployment.
