We’re building the most secure way to share documents.
Designed for the way deals actually run.
Papermark is purpose-built for high-stakes document sharing — fundraising, mergers and acquisitions, IPO readiness, fund reporting, regulated diligence, and client engagements where the wrong viewer seeing the wrong document is not an acceptable outcome.
Founders, M&A advisors, venture funds, family offices, biotech companies, and enterprise security teams in 100+ countries run their most sensitive sharing on Papermark — as a hosted product or fully self-hosted on their own infrastructure. The product is built in public by a community of operators, founders, and open-source contributors on GitHub.
Designed to scale
Papermark is the open-source document infrastructure for modern teams. We help founders, sales teams, and dealmakers share confidential decks, contracts, and data rooms with granular access controls, real-time analytics, and end-to-end encryption. Used by 60,000+ companies across 100+ countries — from pre-seed startups to publicly traded enterprises — Papermark is built in public and backed by a community of operators, founders, and contributors.
Papermark is central to how our company manages deal flow. We use it every day to share documents and run data rooms with our customers and investors.
Our Values
We want Papermark’s values to be a commitment to our customers, a testament to our ambition, and a leading indicator to our candidates and team on the culture we’re building.
Build in the open
Papermark started as an open-source project and that has not changed. The full codebase lives on GitHub, every change ships with a public changelog, and our roadmap is shaped by the people actually running deals on the product. Open is not a marketing label here — it is how we ship and how we earn trust with security-sensitive teams.
Security as a default, not a tier
Watermarks, NDA gating, granular permissions, full audit trails, and SOC 2 Type II controls are not paywalled add-ons. They are the floor. We believe a document sharing tool that cannot prove who saw what, when, and from where is not really a document sharing tool — it is cloud storage with a link.
Move at founder speed
The teams who depend on Papermark most are running a fundraise, closing an acquisition, or finishing a diligence sprint this month, not next quarter. We optimize the product, the support, and the company around that timeline: short release cycles, fast onboarding, and direct access to the people who built the feature you are using.
Stay sharp, stay simple
Legacy data rooms are heavy. Per-page billing, multi-week onboarding, sales gates on basic features. We take the opposite view: a deal room should be set up in minutes, look like your brand, and disappear into the background while the deal happens. The product gets simpler as it gets more powerful, not the other way around.
