Humane AI Pin

🔴Shutdown / Dead

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.

Olive AI

🔴Shutdown / Dead

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.

The brand and apps are gone.

Disco Diffusion

🔴Shutdown / Dead

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 The notebook still loads but is years out of date and runs poorly on modern Colab runtimes.
