witn is outcome-based billing infrastructure for AI agent builders. Teams define what a successful outcome looks like as a billable condition, then send events from their product as the agent works. witn evaluates every outcome against that condition and holds it provisional through a settlement window, so reversals like a reopened ticket are handled automatically. Only results that hold get confirmed. Per-customer rate cards price each outcome, so the same result can cost differently across accounts. A simulation mode replays pricing changes against historical data before they ship. Every invoice line traces back to the exact events that earned it, with an ordered trail that keeps revenue recognition clean under ASC 606. witn bills for resolved tickets, booked meetings, qualified leads or merged PRs. It connects to existing event tools and pairs with Stripe for collection.
