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.
MosaicML built tools for training large language and diffusion models efficiently on commodity GPUs, releasing the MPT-7B and MPT-30B open-source models in 2023. Databricks acquired the company in July 2023 for roughly $1.3B, folding MosaicML's stack into the Databricks platform as the basis for what later became DBRX and the Mosaic AI training service. The standalone MosaicML brand was retired; the team and tech continue inside Databricks.
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.
Rockset was a real-time analytics database founded by ex-Facebook engineers behind RocksDB. It raised $100M+ from Sequoia, Greylock, and Icon, targeting low-latency vector and full-text search for production apps. OpenAI announced the acquisition in June 2024 to power retrieval inside its products. Rockset wound down customer service on September 30, 2024 and migrated technology and team into OpenAI's infrastructure org.
Codeium rebranded its AI IDE as Windsurf in late 2024 and grew into one of the most-used Cursor alternatives. Google announced an unusual $2.4B licensing deal in July 2025 that took CEO Varun Mohan, co-founder Douglas Chen, and the core research team to DeepMind without buying the company. Two days later, Cognition (maker of Devin) acquired the remaining Windsurf product, IP, and employees for an undisclosed sum. Windsurf now operates as a Cognition brand.
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 The notebook still loads but is years out of date and runs poorly on modern Colab runtimes.
Cognition unveiled Devin in March 2024 as 'the first AI software engineer', capable of taking a Linear ticket and shipping a pull request end-to-end. Independent reviewers (notably Carl Brown's analysis) showed the launch demo was carefully edited and that real-world success rates were modest. Cognition kept iterating and acquired Windsurf in July 2025 to give Devin a real IDE surface. The company's valuation reached $4B+ in 2025 funding rounds.
