Shut down - hardware AI assistant

Humane launched the AI Pin in November 2023 with $230M+ in funding and pitches from ex-Apple founders. Reviewers panned battery life, latency, and a laser projector that wilted in sunlight. Sales never materialized, returns outpaced new orders, and in February 2025 HP acquired Humane's IP and team for roughly $116M while bricking existing Pins by month's end. The hardware is now a paperweight; the cloud services that powered it were shut off.

Collapsed - digital health

Babylon Health was a UK telehealth and AI symptom-checker company that went public via SPAC in 2021 at a $4.2B valuation. Its 'AI doctor' chatbot drew regulatory scrutiny from the UK MHRA over accuracy claims. After delisting from the NYSE and an attempted private rescue in 2023, the US subsidiary filed Chapter 7 bankruptcy in August 2023 and the UK operation went into administration. The brand and apps are gone.

Wound down and broken up

Olive was a healthcare RPA-and-AI company that hit a $4B valuation in 2021 after raising over $900M from General Catalyst, Tiger Global, and Vista.

The brand is gone; the website now serves a single sunset notice.

Shut down - early AI art

Disco Diffusion was a free Google Colab notebook by Somnai that combined CLIP-guided diffusion with a community-tuned UI, going viral in early 2022 and seeding the prompt-engineering culture later cemented by Midjourney and Stable Diffusion. Active development on the official notebook effectively stopped in late 2022 once Stable Diffusion released and consumed the open-source diffusion community. The notebook still loads but is years out of date and runs poorly on modern Colab runtimes.

Artbreeder launched in 2018 as a GAN-based image remix tool where users mixed 'parent' images into new outputs. It grew a strong community of character designers and worldbuilders. The team shipped a 'Collager' and a diffusion-based 'Artbreeder Composer' in 2023, but the platform never matched Midjourney or Stable Diffusion on quality and traffic dropped sharply. The site still loads and the subscription remains for sale, but the changelog and social feeds have gone quiet.

Arc receives security patches only; no new features ship. Dia entered closed beta in 2025 and became the company's primary focus.
