CellarTracker
👤 Eric LeVine (13 years building Microsoft Office, then a wine collector himself — the rare founder who WAS the power user he built for.)🌐 siteLinkedIn
An ex-Microsoft wine geek built a cellar tracker for himself; the crowd's notes made it wine's biggest database.
Will it work? · our read
Data compounds. Twenty years of free notes built a lead rivals can't buy — but voluntary pay means CellarTracker earns a fraction of the value its data creates.

xChateau podcast — LeVine on voluntary pay, $57 avg, 750K users, 9.1M notesSubscription Insider — about 8% of registered users convert to paidPulse 2.0 — Eric LeVine interview: 2003 founding, 13 yrs at MicrosoftHarvard Data Science Review — conversation with Eric LeVineWikipedia — CellarTracker
Revenue is undisclosed: LeVine calls CellarTracker "profitable and self-sustaining" but shares no figure. Our "about $2-4M/yr" is an ESTIMATE from first-party inputs: Subscription Insider reports about 8% of registered users convert to paid (tens of thousands of payers), times a roughly $40 real average (suggested tiers $40/$80/$160, avg about $57, min $20). Not first-party revenue, so tagged Estimate, not independently confirmed. Counts vary by source and date: 750K users + 9.1M notes (2021 xChateau) vs 10M+ users + 13M notes (later Pulse 2.0). The "$21B of bottles tracked" is cellar inventory value, NOT revenue. Monetization-ceiling and AI-commoditization risks are [our read]. We never score you.
