About Userlens
Summary
Userlens builds AI agents that act as customer success managers for B2B SaaS companies, handling account research, churn detection, renewals, and upsells across enterprise deals. Its Lumi product monitors individual user behavior inside a product and sends each user personalized guidance to drive adoption, replacing the work a human CSM would do manually across a book of accounts. The target customer is a lean, AI-native software company that cannot staff a CSM for every account it needs to retain and grow.
Business model
A free tier plus paid plans, with a book-a-demo path for larger accounts.
Go-to-market
B2B SaaS product and PLG teams sign up self-serve via a free start, while enterprise prospects book a demo directly with the team.

Agents that renew and expand six and seven-figure enterprise software
Companies today are growing faster than ever with smaller teams. We are making it possible for these lean, AI-native companies to manage enterprise deals. Userlens is building the AI customer success manager. Our goal is to be the CSM for every customer at every company. Every $1-5M of new revenue requires another CSM hire. Userlens breaks that ceiling. Our agents research accounts, catch churn before it happens, and drive renewals and upsells like a top-tier CSM would. We're at $307K ARR, growing 127% month over month, with 30 customers including Smartly (300M ARR). Over 300 CSMs are on Userlens, and 76% of them use it weekly. Built by second-time founders who lived this problem at their last startup.
