Clear withdrawal ruleA withdrawal blocks future licensing. Datasets already licensed stay valid.
Three lines of work
Capture what is missing. Evaluate what you have. Train what comes next.
Most of our work is capture: video for robotics and physical AI, speech for voice AI. Native evaluation and training data run on the same network.

How we build the network
We don’t rent a crowd. We build and qualify one.
Contributors join through Verakin, our network across all five regions of Brazil, and through partner companies that bring their own teams.
- Stage 1SourceRecruitment by profile on demand: region, trade, age range, device.
- Stage 2ConsentTerms read and accepted in the app before the first recording, with version and timestamp.
- Stage 3Brief and practiceTask guides, framing checks and practice rounds before paid work.
- Stage 4Review and deliverOnly approved hours are paid and delivered. Contributors who drift are retrained or rotated out.
The contributor side runs on Verakin: Portuguese-first, mobile-first, paid via Pix per approved hour.Quality and compliance in detail
Capture partners
Real work happens inside companies. We bring them in.
Construction firms, commercial kitchens, cleaning companies and workshops join as capture partners. Their teams record during normal shifts. Participation is voluntary, consent is individual and site rules are agreed in writing before anyone records.
Empresa no Brasil? Seja parceira (PT) →Worksites, not studiosReal sites, real tools, real pace. Nothing staged for the camera.
Volume in one placeMany workers on one site, with a field supervisor nearby.
Site rules in writingOff-limits areas, screens and documents agreed with the company first.
Phone or stereoPhones by default. Stereo head rigs when your spec needs depth.
