In November 2021, Marc Lou was fired from a marketing role with influencer Tai Lopez. He moved to Bali with roughly $20,000 and no backup plan. He had already spent years building small software products that mostly went nowhere — by his own account, four years of side projects that never cleared $3,000 a month.
What changed wasn’t the products. It was the decision to build them in public.
Seventeen products in two years
Lou started posting his work on X as he made it — the wins, the numbers, the products that flopped within a week of launch. He wrote later that in two years he launched 17 products, grew a newsletter to 7,000 readers, and built a Twitter following of 55,000 people. By December 2023, the combined revenue from his experiments hit $65,000 a month, at a 91% margin, with zero employees.
“My solopreneur story: $0 to $65,000/month in 2 years,” he titled the newsletter post recounting it.
One of those 17 products was ShipFast, which he launched on September 1, 2023. It wasn’t a new idea so much as an accumulation — a Next.js boilerplate packaging the authentication, payments, and infrastructure code he’d rewritten from scratch in nearly every one of his previous projects, sold once so other developers wouldn’t have to rebuild it themselves. It became the product that made his name in the indie hacker world, and the base that the rest of his current portfolio grew out of.
A million dollars, a dozen products
By 2025, Lou was no longer running one hit product. He was running a portfolio, and reporting the results of that portfolio publicly every month, the same way he’d reported his early failures.
“I made $1,032,000 in 2025,” he wrote in a year-end newsletter post — a title that also served as the number.
The monthly breakdowns he posted on X through 2025 and into 2026 show a business still anchored in what made him well known. In July 2025, he reported $48,921 for the month: CodeFast at $20,600, ShipFast at $18,200, DataFast at $6,100, and a long tail of smaller products — Indie Page, Zenvoice, LaunchViral, HabitsGarden — filling in the rest. ShipFast and CodeFast alone accounted for roughly 80% of that month’s revenue.
The product that ate the flagship
Eleven months later, the composition of that same portfolio looked almost nothing like it had.
“I made $83,701 in June 2026,” Lou posted on X, breaking the total down by product: TrustMRR at $30,000, DataFast at $21,000, Ship or Die at $15,000, CodeFast at $9,000, his own X account at $4,000, and ShipFast — the product that had defined him two and a half years earlier — at $3,000.
ShipFast had gone from being roughly 40% of his monthly income to about 3.5% of it. It hadn’t failed. It was still generating steady revenue on autopilot. It had simply been overtaken, inside his own business, by products he’d built since.
The one that overtook it fastest was TrustMRR — a marketplace where solopreneurs can buy and sell small SaaS startups, the same kind of businesses Lou himself builds. He posted that it went from $0 to $18,380 in monthly recurring revenue in its first five days. “That’s $220,000 ARR if I’m allowed to dream a little,” he wrote. Weeks later, he announced the platform’s biggest sale to date — an $85,000 acquisition — closing when the marketplace itself was 45 days old. By the time TrustMRR became his top earner, he was posting that the platform had verified over $1 billion in aggregate startup revenue passing through it.
Diversification as the actual product
The lesson in Lou’s numbers isn’t that any single product won. It’s that none of them had to keep winning forever for the business to keep growing.
A solopreneur who depends on one product carries that product’s ceiling as their own ceiling — and its decline as their decline. Lou’s portfolio absorbed ShipFast’s slide from flagship to footnote without the overall number moving in the wrong direction, because DataFast, Ship or Die, and TrustMRR had already been shipped, launched, and given time to find their own customers before ShipFast needed the room.
That’s the part of “build in public” that gets skipped in the summarized version. It’s not just a marketing tactic for a single launch. Posted consistently enough, and honestly enough — including the $3,000 months alongside the $30,000 ones — it becomes a running, verifiable record of what a one-person portfolio business actually looks like as it rotates through products, most likely more instructive to other solopreneurs than any individual launch story on its own.
