Gumroad businesses are attractive acquisition targets — but Gumroad's dashboard shows gross sales before their 10% fee, payment processor fees, and refunds. Verify the real net before you commit.
The problem
Why self-reported data isn't enough
Gumroad charges up to 10% on every sale (plus payment processing). A $100K gross sales figure becomes ~$87K after fees — before refunds. Sellers often lead with the gross number.
Gumroad revenue is often driven by a newsletter or Twitter/X following. If the seller is also selling their social presence, future revenue projections are worthless without understanding the audience retention rate.
Unlike SaaS, most Gumroad revenue is one-time digital product sales. Historical revenue is no guarantee of future revenue — it depends entirely on continued marketing by the new owner.
The fix
ProofCap connects to the seller's GA4 account and pulls 90 days of sessions, acquisition channels, and engagement metrics — verifying traffic quality and volume independently.
We scan the backlink profile for organic SEO signals — referral quality, anchor text distribution, and domain age. This tells you whether traffic is sustainable or dependent on the seller's personal brand.
We compute the implied conversion rate from GA4 sessions vs stated sales volume. If 500 sessions/month are producing $20K in sales, the implied ACV or conversion rate needs explaining.
Our AI synthesizes all signals — traffic, revenue, backlinks, engagement — into a plausibility score with explicit risk vectors and a final M&A-grade verdict.
ProofCap's GA4 integration reads traffic quality directly from Google's API — not from Gumroad's own view count metric, which includes the seller's own visits and is easily inflated.
