Lumen turns raw product events into clear answers. Funnels, retention and AI insights for startups that want to grow on purpose, not by guesswork.
Free up to 1M events a month. No credit card needed.
Powering product decisions at 2,400+ fast moving teams
Everything a product team needs to understand behaviour, from the first click to the renewal. No SQL marathons, no tagging sprints.
Build any funnel in seconds by clicking through real events. Lumen highlights the step that leaks the most and shows who fell out.
Cohort grids that update in real time. Compare any two releases side by side and see which features keep people around past week four.
Every signup, click and upgrade streams in under a second. Ship a feature at 10am and know by 10:05 whether anyone found it.
Type the question you would ask your data analyst. Lumen writes the query, picks the right chart and explains what changed, in seconds.
One snippet, sensible defaults and a privacy model your legal team will actually like.
Drop in one line. Every click, page view and form submit is captured from day one, so you can answer questions you have not thought of yet.
Starter boards for SaaS, marketplaces and apps.
Cookieless mode, PII scrubbing and EU or US data residency.
Lumen learns your normal and flags real anomalies in your team chat or inbox.
Two way sync every 15 minutes. Your data stays yours, always exportable.
Every chart is a query you can open, edit and share.

"We found a leak in our trial flow on the first afternoon. Fixing it lifted paid conversion by 31% in a month. Lumen paid for itself before the invoice arrived."
"I used to spend Mondays exporting CSVs. Now I ask Lumen a question in standup and we have the answer before the meeting ends."
"Setup took one pull request. Autocapture meant we had three months of history the day we decided we needed it."
"The retention grid is the first chart our whole team actually opens. Designers, engineers, sales, everyone."
"We replaced two tools and a spreadsheet nobody trusted. Pricing is clear and the support team replies in minutes."
"Alerts caught a broken checkout on Android at 2am. Without Lumen we would have found out from angry reviews."

An event is any single action a user takes, such as a page view, a click or a custom event you send. Identifying users and updating their properties is always free.
No. Ask Lumen reads your event schema to write queries for you, and every answer links to the exact query it ran. Your data is never used to train models.
Yes. Upload historical events as CSV or JSON, or connect your warehouse and we will backfill up to two years of history at no extra cost.
