Pre launch / Weekend 1
Twitter — viral post
Mark posted a tweet announcing he would build an open-source Docsend alternative. It got ~40,000 views within hours, validating demand before a single line of code was written.
→ ~40,000 tweet views, strong community signal and validation
Launch Weekend
Twitter launch post
After building the MVP over the weekend, Mark posted a launch tweet on Monday sharing the open-source project. The tweet reached ~100,000 views and drove the first wave of users and early paying customers who reached out asking to pay.
→ ~100,000 tweet views; first paying customers acquired organically
Early Growth
Open source / GitHub
Published the full source code on GitHub under an open-core license. This created zero barrier to entry — developers could star, fork, self-host, and contribute. The public repo acted as a perpetual inbound marketing asset and trust signal.
→ 7,000 GitHub stars; 60 contributors; continuous inbound developer interest
Early Growth
Build in public — Twitter / LinkedIn
Consistently shared incremental progress — even incomplete features — on Twitter and LinkedIn. The philosophy was 'nothing to hide behind,' so every small ship became a public update that compounded community growth and customer awareness.
→ Steady community growth and customer conversion from free/self-hosted to paid hosted
Month ~6 12
Open source hackathon hacktoberfest
Participated in Hacktoberfest, a month-long open-source hackathon. This brought in new contributors, accelerated feature shipping velocity, and raised project visibility in the developer community.
→ Increased contributor base and shipping velocity; attracted users noticing faster feature releases vs. incumbent slowness
Year 1
Open core freemium conversion
Offered free self-hosting for the core product while monetizing through a paid hosted version (papermark.com) for non-technical users, plus an enterprise license for advanced features on self-hosted infrastructure. This funnel converted self-hosters who didn't want maintenance overhead into paying customers.
→ $20,000 MRR by end of Year 1
MRR $20k
Year 2 (mid)
Community driven product velocity
Leveraged 60+ open-source contributors to ship features faster than incumbents (Docsend, legacy data room providers). As feature parity was reached and then surpassed, users began switching from incumbents. The faster shipping cycle itself became a growth driver — customers noticed Papermark was building while competitors stagnated.
→ $75,000 MRR; ~30,000 users; ~1,000 paying customers; 800,000 document views
MRR $75k Users 30k users
