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.

03Weight class — CENTStap an axis
Control Low
Doesn't own the data or the platform; resells third-party API data through Microsoft and Google add-in stores.
04The key move
Formula, not dashboard.
Rivals built web dashboards and told investors to leave their spreadsheets. It did the opposite: put the data behind =WISE(), so people keep their own models — the fit that drives word-of-mouth retention.
fact
The counter-intuitive move
But the same formula that locks users in also caps Wisesheets: it lives or dies by what Excel and Sheets allow, and by data it licenses from others.

05Where the moat is
What actually keeps it sticky:
Models built on =WISE() are painful to rip out30 years of history, 50+ exchangesOrganic SEO and word-of-mouth built over yearsA fraction of Koyfin and Bloomberg's price
06How it diesmedium confidence
It dies if its upstream data supplier revokes the API or hikes fees past what a $5-10/mo plan can bear, or if Microsoft or Google ship native financial functions that make a paid add-on redundant. our read
Show evidence · counter
Evidence: GOOGLEFINANCE has offered free basic quotes for years, yet Wisesheets still grew — native functions haven't matched its depth so far.
Counter: It already blends multiple data sources and serves 1,000+ firms, so no single supplier or platform tweak is instantly fatal.
07Against rivals
Bars = fit for a DIY retail investor; price is real monthly cost. Wisesheets wins on price and workflow, not raw data depth. our read

★Would it work for you?
Which expensive pro tool could you unbundle into the workflow people already live in?
Its edge was distribution: data where users already work. Where do you have that kind of access? We don't score you — you answer.

<case name="Wisesheets" model="data">
What it does: Wisesheets sells a spreadsheet add-on that pulls 30 years of stock financials into Excel and Google Sheets through a =WISE() formula, on $60-120/yr plans.
Why it won (moat): Once an investor's models reference =WISE(), switching breaks every sheet; 30-year data breadth and years of SEO deepen that workflow lock-in.
Weakest axis (CENTS): Wisesheets resells data licensed from third-party APIs and ships inside platforms owned by Microsoft and Google, so it controls neither its supply nor its channel.
How it could die: Wisesheets dies if a data supplier hikes fees beyond a $5/mo plan, or if Excel and Sheets add native financial functions that make the paid add-on redundant.

<task>
Be a skeptical operator, not a cheerleader. No generic startup platitudes. If my angle is weak, say so plainly.
First, a reality check: markets like this mostly fail. State the honest base rate (how crowded/hard is this?) and the ONE specific thing that would have to be true for ME to be the exception — grounded in my profile above.
Then a compact table:
- Fit — does this pattern suit my edge, or fight my gap?
- Angle — my sharpest differentiation vs Wisesheets (concrete, not "better UX")
- Distribution — exactly where my first 100 users come from (this is the hardest part — be specific, not "content marketing")
- Risk — its "how it dies" (above) in MY situation
Finish with one line: "The single thing to do next."
Use only the facts above; if data is thin, say so — never invent numbers.
Then stay with me and go deeper on whatever I ask — tech stack, rough cost & time, the smallest MVP to test, pricing, or timing.

wisesheets.io — product, pricing ($60-120/yr), statsProduct Hunt — Wisesheets, launched 2021 (94 upvotes)FinTech Magazine — 70k+ users, sub-$10/mo positioningLinkedIn — Guillermo Valles, founder & ex-REIT analystKoyfin pricing — rival at $39-79/mo (context)
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.
