Userlens is an AI customer success platform built around agentic CSMs that aim to never miss churn signals or upsell opportunities. The system monitors accounts for churn signals, adoption metrics, and engagement patterns across product analytics, CRM, billing, and support tools. It generates talking points and QBR decks based on each company's playbooks to help teams upsell and renew large deals. The company is based in Helsinki, Finland, was founded in 2025, and is part of YC's Spring 2026 batch.
