Dot was a personalized AI companion app built by New Computer, founded by Sam Whitmore and ex-Apple designer Jason Yuan. Launched on iOS in June 2024, it aimed to act as a friend and confidante that grew more tailored to each user over time. In September 2025 the founders said their long-term visions had diverged, and rather than compromise either one they chose to wind down the company. The app ceased operations on October 5, 2025.

On May 4, 2025, the site went offline permanently after a critical service provider terminated support, causing major data loss.

Noogata, an Israeli enterprise AI analytics startup built inside Team8's venture platform, raised about $28M and signed marquee customers including PepsiCo and Colgate.

Cruise was the GM-funded autonomous driving company that operated robotaxis in San Francisco, Phoenix, and Austin. After an October 2023 incident in which a Cruise vehicle dragged a pedestrian 20 feet, the company suspended California operations and entered a year of regulatory and leadership crisis. GM announced the full wind-down of the robotaxi program in December 2024, citing $10 billion in cumulative losses. The remaining technology was folded into GM's consumer ADAS efforts rather than run as an independent service.

Forward Health was the AI-augmented primary care clinic chain founded in 2016 by Adrian Aoun (ex-Google, founder of Wavii). It reached a $1B+ valuation around 2021 by combining physical clinics with AI diagnostic tools. CarePods — self-service AI clinic kiosks — launched in 2023 to mixed reception and never scaled. Forward shut down all operations in November 2024, with Aoun citing operational complexity and inability to reach profitability. The shutdown became the canonical example of why AI primary care models that include physical clinics face economics that pure-software AI avoids.

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.

Argo AI was the autonomous driving software company that Ford and VW jointly invested ~$7B in across six years. Founded in 2016 by Bryan Salesky (ex-Google) and Peter Rander (ex-Uber ATG), Argo developed Level 4 tech and ran robotaxi pilots in Pittsburgh, Miami, and Austin. Ford and VW jointly pulled funding in October 2022, citing that the timeline to commercial Level 4 exceeded their planning windows. Ford spun up Latitude AI internally to absorb some Argo talent and refocus on Level 2/3 driver-assistance for production vehicles.
