Agentic skills intelligence for hiring, developing, and planning talent
Technical, business, agentic, behavioral, and diagnostic evaluations built around real job tasks.
Structured conversational interviews that give teams clear skills evidence early in the funnel.
A shared workspace where candidates solve real problems while interviewers observe how they work.
See where your workforce is strong, spot gaps early, and plan hiring, mobility, and redeployment.

Proving grounds for agents and engineers who ship real work.
Build realistic networks — web apps, file shares, databases and internal hosts — for training and evaluating offensive-security agents under rules of engagement.
Load any open model, run it offline on your own GPU, inspect which neurons fire per word, then edit and serve the modified model via an OpenAI-compatible API.
Work across repositories, talk to your code by voice, and let agents plan, edit, test and open pull requests from the browser, with every session traced and scored.
Agents search engineers' real work across GitHub and LinkedIn and score candidates against the role, producing a ranked shortlist with evidence.
