$112 vs $134. A Gumroad seller with 8 or more products earns a median $112 per product — less than the $134 a solo seller earns with one. The "keep shipping, build the catalog" advice produces exactly the catalog sizes that perform worst.
"How many products should I sell?" usually gets answered with vibes. I pulled the actual curve from 24,724 active sellers in our database of 152,362 active Gumroad products (April 2026 data). It's a bell curve, and the peak comes early.
TL;DR — revenue per product by catalog size
| Catalog size | Median revenue per product | vs. baseline |
|---|---|---|
| 1 product | $134 | Baseline |
| 2-3 products | $187 | +40% vs solo — the peak |
| 4-7 products | $167 | -11% vs peak |
| 8+ products | $112 | -16% vs solo, -40% vs peak |
Read the last row twice. Eight or more products earns less per product than never shipping a second one.
The second product is worth 5x the first
The 1-to-2 jump is the best move in the dataset. Software development shows it most dramatically, across 1,946 sellers:
- 1 product: $198 median revenue, 2.83% reach $10K+ (n=1,203)
- 2-3 products: $987 median revenue, 18.03% reach $10K+ (n=743)
That's 5x the total revenue and 6.4x the odds of crossing $10K. In absolute numbers: 134 software-dev sellers with 2-3 products have passed $10K in our database.
The mechanism is boring and reliable. Your first product builds your email list and proves you can solve a problem. Your second sells to buyers who already trust you — and an existing list converts roughly 10x better than cold traffic. Same audience, second offer, near-zero acquisition cost.
Why revenue per product collapses after 3
Two forces shape the bell curve:
The catalog effect (1 → 2-3 products). A buyer who lands on your page sees a catalog, not a one-shot experiment. The profile reads as serious. And a buyer of product A has a real chance of buying product B. Each product feeds the others.
Quality dilution (4+ products). Past three, attention spreads thin. Updates stall, questions go unanswered, refinement stops. Gumroad's algorithm can't push every listing from a single creator, so each new product gets less visibility. The market starts reading you as a generic catalog instead of an expert.
Software-dev puts the dilution in hard numbers: per-product profitability runs $487 at 2-3 products and $234 at 4-10 — a 52% drop.
It holds in 5 out of 5 categories
Aggregate patterns sometimes flip when you segment the data (Simpson's paradox). Not this one:
| Category | 1 product | 2-3 products | Lift |
|---|---|---|---|
| Design | $112 | $187 | +67% |
| Drawing | $89 | $143 | +61% |
| Software | $189 | $278 | +47% |
| Education | $145 | $212 | +46% |
| Business | $167 | $234 | +40% |
The anecdotes line up with the data. Marc Lou runs 3 active products. Tibo Louis-Lucas runs 2. The two most visible creators in the indie ecosystem sit exactly on the sweet spot.
What to do, by catalog size
1 product? Build your second now. Launch it within 6 months, and make it complementary: if your first product is a boilerplate, the second is an extension kit, a template pack, or an optimization guide. You're selling to the same buyer. If you're working toward a first $10K, the zero to $10K infoproduct guide covers the build process — the data here tells you when the odds shift.
4-7 products? Stop creating, start improving. You're at $167 per product, 11% below peak. Better covers, richer descriptions, real updates. Quality beats quantity from here.
8+ products? Archive the weakest. A $112 median means weak listings are dragging the whole profile below solo-seller territory. Marc Lou is at 3. Tibo is at 2. Not 12.
Catalog size is one of two compounding levers we've quantified. The other is social proof: crossing 6 reviews lifts median revenue by 438%, measured causally in how Gumroad reviews drive revenue.
