What Userlens is
Userlens is a customer adoption and retention platform for product teams, backed by Y Combinator. At its core is an adoption agent called Lumi, which reads product behavior and turns it into personalized prompts that nudge users toward key features. Rather than sending the same message to everyone, it reacts to what each user actually does, such as tasks completed and features used. You can build campaigns with clear goals, then deliver guidance through channels like email and in-app pop-ups. A free trial and demo booking are offered.
What you can do with it
- Track per-user behavior such as task completion and feature use
- Turn that behavior into personalized guidance prompts
- Run campaigns with clear adoption goals and target audiences
- Deliver real-time guidance through email and in-app messages
Who it is for
- B2B SaaS product teams focused on activation
- Product-led growth teams that lean on in-product value
- Product managers and operators watching usage metrics
What to watch out for
A free trial is offered, but paid pricing is not detailed and can change, so confirm terms before you commit. Getting value requires connecting your product data, so setup effort depends on your current stack. Adoption gains usually build over weeks, so a very short trial may understate the results. Treat the guidance as prompts to support users, not as a guaranteed lift in retention. Start with a small sample to confirm the output meets your expectations before processing the full batch. Free tiers and usage limits can change, so check the current rules on the official page before relying on it long term. When quality matters, export a small draft first to confirm the result before producing the final file.
