Stratumn is a French technology company founded in 2015 that developed a "Proof of Process" platform using blockchain technology to create verifiable, tamper-proof audit trails for multi-party business processes. Headquartered in Paris, the company targeted enterprises and regulated industries that need cryptographic proof of compliance across complex workflows involving multiple organizations.

Stratumn's platform worked by recording each step in a business process as a cryptographically signed event, anchored to public blockchains (including Bitcoin and Ethereum) for immutable timestamping. This enabled organizations to prove the integrity and sequence of their operations to partners, auditors, and regulators without exposing sensitive underlying data. The technology was applied to use cases in insurance, supply chain management, and financial services.

The company raised funding from notable investors including Nasdaq Ventures and Otium Venture, and partnered with enterprises in the French and European markets. Stratumn was part of the broader wave of enterprise blockchain startups that emerged in the mid-2010s, offering cryptographic verification as an alternative to trust-based inter-organizational processes. The company operated through the late 2010s and early 2020s as the enterprise blockchain market matured and consolidated.
