Typebot: Stuck at $100 MRR for 8 Months, Then Open Source and a Brazilian Tailwind Took the Solo SaaS to $623K a Year

Where should you cut your losses on a SaaS that isn’t selling? There is an extreme counterexample to every rule of thumb. Typebot, the chatbot builder French developer Baptiste Arnaud released in June 2020, reached only $100 in MRR over its first eight months. Three and a half years later, in October 2023, MRR stood at $31,000. Per GetLatka’s data, annual revenue was $344K in 2023 and an estimated $623.1K in 2024, 81% year-over-year growth. Headcount is still one; outside funding, $0.

Typebot is a no-code builder for conversational forms and chatbots, inspired by Typeform’s conversational UX. The market is crowded, and it hardly looks like territory where a late-arriving solo developer can fight head-on. Indeed, the launch was as bleak as the numbers above suggest. What makes the case interesting is that the following three and a half years feature nearly every card a stuck solo SaaS can play: a lifetime deal, going open source, and a tailwind from an entirely unexpected market.

The timeline

Cross-checking the numbers: from $2.7K MRR in December 2022 to $31K in October 2023 is roughly an 11x jump in ten months, an abnormal slope for SaaS, and the Brazilian breakout sits inside that window. Meanwhile, the two and a half years from launch to end-2022 were essentially flat apart from the $23K lifetime deal. The growth comes as long stagnation and short spikes, never as a continuous climb.

The $23K lifetime deal was bridge financing

The April 2021 lifetime deal, selling perpetual licenses outright, brought $23K and more than 900 users in three weeks. For a business at $100 MRR, that is equivalent to more than two years of revenue, and for a solo developer who won’t raise, it functions as de facto bridge financing.

But the subsequent numbers also expose the model’s limits. Per Superframeworks’ analysis, Typebot needed “a long two years” after the deal to reach $3K MRR. Lifetime customers hand you cash and an initial user base, but they never compound into recurring revenue. The dividing line is whether you use the time the deal buys to build a recurring-revenue engine, in Typebot’s case, that engine was open source. The sequence echoes Youform, another form-builder that combined a limited-time lifetime deal with a free tier to reach $18K MRR.

Inside the open-source bet

In November 2021, Arnaud decided to rebuild Typebot as open source. By his own account on Indie Hackers, the license is AGPLv3: anyone can run a commercial Typebot, but then must publish their source. Technically, he dropped the Firebase dependency for Prisma + PostgreSQL, making self-hosting realistic. After Typebot 2.0 shipped on February 15, 2022, MRR moved from $300 to $960 by June.

The business model is a hybrid: free self-hosted version plus paid cloud version. If the code is free, why pay? Arnaud’s answer is simple: because hosting a project yourself is a pain. Open source bought user trust through transparency and borrowed contributors’ hands. As a mechanism that supplements a solo developer’s limited resources on both the trust and engineering fronts, it worked, a structure closely resembling Plausible, which also weaponized open source to grow a Google Analytics alternative to $1M ARR with four people.

Could the +88% from Brazil have been engineered?

In June 2023, a marketing influencer in Brazil shared Typebot with their audience, and revenue grew 88%. This episode, reported in Superframeworks’ analysis, is the crucial inflection point in the run from $2.7K to $31K, and it was not a campaign Arnaud designed. You can argue the free self-hosted version and a product usable across languages created a “shareable state,” but when and where the fire catches is not under anyone’s control.

For the repeatability discussion, these must be kept separate. Going open source and running a lifetime deal are decisions you can copy. The stochastic viral moment that ultimately set the slope of the growth curve can only have its odds improved. Then again: had he folded during the eight months at $100 MRR, that lottery ticket would never have existed.

Conditions for repeatability, and the limits

Some of this travels beyond chatbots. Using a lifetime deal to secure cash and users before recurring revenue exists is a realistic option for an unfunded solo SaaS, and in a crowded market a latecomer can differentiate on distribution form, open source plus self-hosting, rather than features. Surviving the stagnant years on a near-zero-payroll structure is the further precondition for being around when the tailwind arrives.

The caveats: the 2024 figure of $623.1K is GetLatka’s estimate, not the founder’s confirmed disclosure. And publishing under AGPLv3 permits commercial clones, so the strategy presupposes winning indefinitely on cloud-version operational quality, an equilibrium that rests on Arnaud’s personal engineering capacity. The lesson is not “go open source and you will grow,” but “changing your distribution can carve out a place in the market, even for one person.”
