Userlens

Userlens develops an AI customer success manager (CSM) for B2B software companies. Its agents monitor every account in a book of business, research accounts, flag churn risk ahead of renewal dates, and prepare talking points and quarterly business review (QBR) decks based on a customer's own templates and playbooks. The stated goal is to remove the constraint that each additional $1-5M of new revenue requires another CSM hire, targeting lean, AI-native companies that need to manage enterprise deals.

The product connects to product analytics tools (PostHog, Amplitude, Mixpanel, Segment), CRMs (HubSpot, Salesforce, Attio), billing (Stripe), and support tools (Intercom, Pylon). Setup is described as taking a day, with up to three months of historic data import offered during pilots. The system surfaces signals such as declining feature usage, champion role changes, and frustration threads in Slack that a customer team might otherwise miss. An earlier positioning of the company described it as combining product analytics and customer feedback to show what drives customer satisfaction or churn, and as an always-on layer for customer success that analyzes accounts, learns what good behavior looks like, and directs teams where to focus.

Founding story

Userlens was founded by Ankur Dahama and Hai Ta. At their previous startup, Wudpecker, the founders had 25,000 users and more than 1,000 customers but no visibility into which accounts were about to churn, discovering losses only at renewal; they built Userlens as the tool they wished they had. Dahama previously founded Wudpecker, which grew to more than 20,000 teams, and earlier worked on engine simulation at Mercedes-AMG and system software for a nuclear reactor.

Business model

B2B SaaS sold to software companies, with pilots that include historic data import and a promotional free three-month period for Y Combinator companies.
