Surveys tell you what. Voice tells you why.
Exit surveys force customers into a dropdown. Outro lets them talk - then AI transcribes the interview, detects the real cancellation reason, and shows the matching save offer while they're still on the page.
Choose Outro if
You want voice interviews and AI reason detection instead of survey checkboxes, unlimited responses, or a price that matches an early-stage budget.
Choose ProsperStack if
You're on enterprise billing infrastructure and want native subscription-provider integrations with session-based pricing.
