Sell expert data and RL environments to AI companies: 10 buyers, what they pay, on what terms

The list holds 10 data buyers for expert data and RL environments. Two publish a rate, both hourly. Mercor pays "experts $100 to $500/hr". Mindrift pays "up to $20 per hour". Prime Intellect pays "bounties per environment" and Datacurve is "paid per bounty", with no amounts published. Surge AI, Scale AI and Handshake AI keep their prices undisclosed.

No editor's pick is set for this hub. Prime Intellect opens the list: it pays bounties per environment, sets no minimum, and reports 2,500+ community environments. Mercor buys expert work and company data, varies on exclusivity, and reports a gross run-rate above $2B (Jun 2026). Datacurve pays engineers per bounty for coding tasks on exclusive terms and raised a $15M Series A in Oct 2025. HUD buys RL environments and is reported to acquire codebases, with no published price.

Two of the 10 license non-exclusively: Troveo AI and Opendatabay. Datacurve and Mindrift are exclusive, five vary by deal, and HUD does not say. Most work here is paid per hour or per bounty, so check whether the contract assigns your output outright or licenses it. Check what happens to an environment or task the buyer rejects, and whether prior work you bring in stays yours. Read confidentiality terms before you take on work for a named lab.
