@deedydas the honest answer is that most startups selling ai training data are actually middlemen for big labs to cut costs and streamline their pipelines, not driving innovation themselves
@deedydas I thought Arena was at a 100M run rate? https://techcrunch.com/2026/06/29/arena-the-ai-leaderboard-everyone-uses-is-now-a-100m-business/
@deedydas 4 companies making up 75 percent of that revenue is a striking concentration. Good breakdown of a market most people don't think about
@deedydas wow casual @ProximalHQ erasure

Listing out some of the others I missed: Data marketplaces: Kled, Luel Computer / browser use: Chakra Labs, Habitat, Refresh, Cua, Originator, Dojo Coding / SWE: Proximal, Idler, Calaveras, BenchFlow, Vmax Long-horizon / reasoning: Andromede, Aviro, AIChamp, General Reasoning, Champ, Haladir, Hillclimb Model behavior / evals: Gray Swan, Theta, Preference Model, Vals AI, Andon Labs, Verita, Good Start Labs Domain-specific: Halluminate, Quesma, Phinity, Rise Data Labs, Kairos, TrainLoop, Huzzle Labs
Full AI Training Data startups list (July 2026) >50 cos sell training data and RL environments to the big labs and are a key driver of AI progress. They total ~$8.5B in revenue and ~$100B in market cap. Scale, Surge, Mercor and Handshake are the giants with >75% of the market. https://x.com/deedydas/status/2076074699600372223/photo/1
Every single startup selling AI Training Data (July 2026) >50 cos sell data and RL environments to big AI labs and drive AI progress behind the scenes. They total ~$8.5B in rev and ~$100B in valuation, >75% of which are just 4 players: Scale, Surge, Mercor and Handshake. https://x.com/deedydas/status/2076124392711696455/photo/1
I know a lot of these are underreported revenue numbers! Some are genuine mistakes (Arena is at $100M). For others, I try to only use public sources for revenue and valuation, including rumors. If you want to correct any, what’s most helpful is just telling me the correct number and a source so I can fix in the next version.
If there's any startups I missed or any numbers you have issues with, please let me know and I'll fix them in the next iteration. Really hard to get these to be perfect, but I've taken the perfect is the enemy of the good approach to some of these lists because some find them valuable
