Wisesheets
👤 Guillermo Valles (Ex-REIT analyst who moved $1B+ in deals. He had a pro data terminal at work, felt its loss investing at home, and rebuilt it.)🌐 siteLinkedIn
An ex-analyst missed his work data terminal, so he rebuilt it as a spreadsheet formula for retail investors.
Will it work? · our read
Workflow lock-in. It resells data it does not own and wins on price. Sheets' free GOOGLEFINANCE covers the basics; if an API supplier hikes fees or a giant deepens that, margin and moat both thin.

Revenue is NOT disclosed. Wisesheets is bootstrapped and private; the $400K-700K/yr band is our estimate [our read], derived from first-party stats (70k+ users; company PR says "thousands of paying customers") times published $60-120/yr plans. Real ARR could be higher given $900/yr enterprise tiers and 1,000+ firms cited — treat the number as a floor-ish estimate, not a reported figure. First-party and verifiable: pricing, user count, 370M/mo requests, 2021 Product Hunt launch, and the founder's SmartCentres REIT-analyst background (site, Product Hunt, company PR). Competitor prices are from Koyfin and Bloomberg public pages. No drama claimed — this reads as a patient SEO-and-word-of-mouth grind by a domain insider, not a single clever stroke. We never score you.
