An open-source DocSend alternative that helps teams share and track sensitive documents, reaching $3M ARR while bootstrapped.
2-person core team
Papermark sat in Marc's repo for over a year; one tweet promising an open-source DocSend alternative drew hundreds of likes, a copycat launched two days later, and that public deadline turned a side project into a $3M ARR company.

Papermark is an open-source alternative to DocSend for sharing documents with teams that need controlled access and engagement insight. Iuliia Shnai and her husband Marc Seitz built the company together and bootstrapped it to $3 million ARR; the host congratulates them on hitting that mark a couple of weeks before the recording, and Iuliia talks about the next step from $3 million to $5–10 million. Marc had kept an early version in his repository for more than a year. The project moved to the front when a public post about building it drew strong interest and another person launched a competing idea soon afterward, prompting Marc to ship. Iuliia had spent years trying other products, including a LinkedIn post generator, while posting regularly on social platforms. When that product developed 20%–25% churn, she shifted more effort toward Papermark and helped attach payments. The founders later described a two-person core supported by agencies and contractors. The host reports the headline revenue; no financial dashboard or third-party filing is presented, so treat the ARR as creator-reported.
For Papermark, a document-sharing product aimed at fundraising teams, the first customers are easiest to reach where founders already discuss investor updates, pitch materials, and deal rooms.

Data credibility: The $3 million ARR figure is stated by the podcast host in the intro and when congratulating the founders; cofounder Iuliia Shnai does not dispute it and frames her next goal as moving from $3 million to $5–10 million. No dashboard, customer count, or pricing is shown, so the number is creator-reported and unaudited. The 20–25% churn figure refers to her earlier LinkedIn post generator, not Papermark. The auto-captions spell her name as Julia Schnee.
Papermark started as an open-source project, and the founders later attached payments while Iuliia redirected effort from her own LinkedIn post generator. Once checkout was live, Papermark overtook the revenue of her LinkedIn tool, which she had been selling for $6.99 a month, very quickly.
Papermark’s growth loop can connect public distribution, product usage, and trust. The founders shipped an open-source DocSend alternative after Marc’s build-in-public post attracted attention; users who share a document create another opportunity for recipients to encounter the product.
Papermark emerged after a long sequence of experiments, so a founder building this kind of workflow should expect launches that draw little sustained demand.
