Arc launched in 2022 with a sidebar-tab layout and a cult following. The Browser Company raised $50M to build it, then announced in October 2024 that Arc was too complex for mainstream users and that all new development would shift to a new AI-first browser called Dia. Arc receives security patches only; no new features ship. Dia entered closed beta in 2025 and became the company's primary focus.

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.

Multi (formerly Remotion) was a Mac video collaboration tool that let small teams co-edit screens with rich AI-assisted features. OpenAI announced the acquihire in June 2024, the entire team joined OpenAI to work on collaboration in ChatGPT, and the Multi product was shut down on July 24, 2024. The site now redirects to OpenAI.

Global Illumination was a small NYC studio founded by ex-Instagram and Facebook engineers that built creative tools and a Minecraft-style sandbox game called Biomes. OpenAI announced in August 2023 that it had acquired the company in its first-ever acquisition; the team joined OpenAI to work on core products including ChatGPT. The Biomes code is open-source but the company brand was retired.
