DataFast
👤 Marc Lou (Marc Louvion) (Spent three years launching tiny startups in public to 200K X followers, then shipped the analytics tool those makers needed.)🌐 sitemarclou.com𝕏
He didn't hunt for users. He launched to 200K makers who were already his exact customer.
Will it work? · our read
Audience-first. Solid analytics, but the moat isn't the code. Marc Lou sold to a 200K-follower audience he built over three years. Rivals copy the tool, not the crowd.

Revenue is Stripe-verified on TrustMRR (itself a Marc Lou product) — a live first-party dashboard, not an audited filing, so STATED not FILED. MRR was $24,635 and all-time gross $228,851 as of Jul 20 2026; TrustMRR updates live, so the exact figures drift. User count 20,481 and $9-19 pricing are from datafa.st; audience figures (about 200K X followers, 42,851 newsletter subscribers) are first-party from his own pages. DataFast took no outside funding. Attribution/traffic volume is not revenue; the headline is subscription MRR. Founder is French, based in Bali; region marks his nationality. We never score you.
