The AI-native ATS that replaces your entire recruiting stack
Pipeline management, talent pools, outreach templates and automated sourcing live in the same system, removing handoffs between tools.
Résumés are ranked against role fit, summaries are generated automatically and pass-through rates stay visible in structured workflows.
Interviews are captured and scorecards auto-filled so structured feedback lands in the candidate profile instead of a separate tool.
Calendar syncing, automated reminders and workflow triggers replace the back-and-forth email chains with candidates and hiring managers.

The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
