Ask any lab where their model is weakest and the answer is rarely 'creative writing.' It's the physical world: electrical fault-finding, machining tolerances, crop disease, aircraft maintenance procedures. The people who hold that knowledge have one thing in common — they are not signing up for annotation marketplaces.
Why the supply never shows up
- A working electrician isn't browsing gig platforms; the platforms are built by and for people who live online.
- Marketplace vetting can't validate a trade anyway — there's no take-home test for two decades of panel work.
- Piece-rate task pricing insults skilled hourly professionals, so the few who arrive don't stay.
Recruiting from records, not ads
Our network wasn't assembled through sign-up funnels. It accumulated over ten-plus years of employing and paying professionals — 15M+ of them across 120 countries. That includes electricians, mechanics, CNC operators, energy and agriculture specialists, aviation technicians, defense-sector engineers, and complex industrial and manufacturing specialists. We know who they are because their contracts, tenure, and roles are in our records — and we can reach them directly, as former colleagues rather than cold ad impressions.
So when a lab needs a hundred verified machinists to evaluate a manufacturing copilot in four languages, that's not a recruiting moonshot. It's a query.
The frontier of model capability is the physical world. The frontier of data supply is the people who work in it.
