I build and sell C++/Blueprint plugins and build-automation tooling for Unreal Engine 5 developers. Every sale to date has been organic — someone searched for a problem, found my tool, and bought it. I have never run an ad.
Three facts about this business, in the order that matters.
No ads, no outbound, no content marketing, no mailing list. 100% of revenue came from marketplace search and organic traffic. The product is already past the question of whether anyone wants it.
A marketplace customer leaves a few dollars after platform fees. A customer on my own store leaves $70.66 on average and I keep nearly all of it. The same person, ten times the value, depending only on where they land.
Digital products with the source code already written. The hundredth sale costs exactly what the first one did: nothing. Every incremental dollar of revenue is almost entirely margin.
Nine consecutive months of paid revenue across two channels. Figures are net payouts actually received, not gross bookings.
Direct store sales began in May 2026, when the storefront launched. Marketplace payouts settle on a delay, so a given month's payout reflects sales closed one to two months earlier. Revenue is lumpy by nature: a single bundle sale moves a month by 20%.

17 transactions, 15 distinct customers since launch. The best-selling item is the Complete Bundle — 11 copies sold, $970 in revenue at its launch price of $99. It now lists at $299. People buying direct buy big.
Historical marketplace orders, after the platform's cut. Reach is free; margin and the customer relationship are not mine.
18 production plugins with full C++ source and Blueprint support, sold individually on Fab and in the direct store, or together as the Complete Bundle for $299 (over $1,000 bought one by one). Prices below are current direct-store list prices.
Higher-ticket software for studios, with the engineering finished and licensing, trials and payments live in production. None of them has had a launch campaign — there has been no budget to give them one.
See which code is eating a game’s memory. Memory, frame time and CPU of a running game in any engine (Unreal, Unity, custom C++), a clickable 3D memory map down to function, file and line, before/after comparison also in CI. 14-day free trial.
Record a play session on a tester’s PC and replay it step for step, including stepping back. Captures input, random numbers, time and iteration order, and names the exact step where a replay diverged. Integrates with one compiler flag.
Makes an AI coding agent (Claude Code) prove an Unreal build works before it says “done”: compile gates, log gates, automation tests, screenshot checks, packaging. 167 MCP tools for UE5, one Windows installer, CI exit codes.
Market research for indie developers: every Steam indie release from the last 12 months with reviews, prices, launch dates and live player counts. Free download that collects e-mail addresses — a lead source for the paid tools.
The product is proven. The catalog is built. The licensing infrastructure runs. The single missing input is reach — and reach is the one thing that costs money I have not had.
| Allocation | Amount |
|---|---|
| Sponsored tutorials with Unreal Engine YouTubers — 6 videos | $3,600 |
| Gamedev newsletter placements — 8 slots | $2,400 |
| Own tutorials and documentation (organic search) | $1,800 |
| Demo video production for every marketplace listing | $1,600 |
| Developer communities — Reddit, Discord | $1,000 |
| Analytics, conversion tracking, price testing | $800 |
| Reserve, allocated to whichever channel proves out | $1,200 |
| Total | $12,400 |
Four of these line items produce assets rather than impressions. A sponsored tutorial, a written guide and a listing video keep working after the budget stops; paid clicks do not. At a $70 average order value, paid search and paid social cannot clear their own cost — so they are not in the plan.
Anything a reasonable diligence process would surface, stated upfront.
$486 per month on average, with a range from $101 to $1,175. This is an early, lumpy revenue line — a single bundle sale materially moves a month. It is a proof of conversion, not a stable cash flow.
Of 17 direct transactions, 9 were entered manually into the ledger during the store's early months; 8 are automatically captured through PayPal IPN and card processing with full transaction records. Marketplace payouts are independently verifiable in full. Complete documentation available on request.
I write every line of code and run every part of this product line myself. That keeps costs near zero and decisions fast, and it concentrates key-person risk. The products are shipped with full C++ source, which limits customer exposure if I am unavailable.
73% of revenue to date came through Fab, where pricing, search ranking and fees are outside my control. This is precisely the dependency the raise is intended to reduce by growing the direct channel.
I have never run a campaign, so there is no historical CAC to point at. The case rests on a proven organic conversion rate and a $70 average order value, not on a measured paid funnel.
