Stampery has raised $600K in total across 1 funding round.
Stampery develops a blockchain-based data certification platform, providing immutable verification and legal proofs for sensitive documents and communications. The company's core offering leverages the inherent security and transparency of blockchain technology to ensure the existence, integrity, and attribution of digital information without relying on central authorities. This technical approach guarantees an unalterable record, bolstering trust and authenticity for various digital assets.
The company was founded in 2014 by Daniele Levi and Tommaso Prennushi, alongside others. Their foundational insight stemmed from the growing need for irrefutable digital proof in an increasingly interconnected world, recognizing blockchain as the ideal infrastructure to establish verifiable authenticity and prevent data tampering. This vision aimed to bring cryptographic certainty to everyday digital interactions.
Stampery's services cater to organizations requiring robust proof of data integrity and timestamping for legal, compliance, and operational purposes. Its product helps businesses secure their digital footprint and build auditable trails for critical information. The company’s long-term vision centers on establishing a global standard for digital trust and data certification, ensuring that the authenticity of any digital record can be instantly and independently verified.

Stampery is a technology company that builds blockchain-based data certification services, leveraging Bitcoin and Ethereum blockchains to verify the existence, integrity, and attribution of communications, processes, and data for organizations.[1][2][3] It serves businesses needing secure, tamper-proof proofs—such as legal professionals, enterprises in supply chain, logistics, and auditing—solving the problem of trust in digital records by replacing reliance on insiders or third parties with mathematical, independently verifiable proofs.[1][3][4] Key products include BTA (Blockchain Timestamping & Anchoring) technology, which processes up to 10⁹ datasets per second via a public API, generating cryptographic proofs without exposing raw data, and simple integrations like email, Dropbox, or API for certifying documents.[2][4] Stampery demonstrates growth through patents (3 granted, including systems for data unit certification), open-source tools on GitHub, and early recognition at TechCrunch Disrupt SF in 2015, positioning it as a leader in blockchain infrastructure for accountability and auditability.[1][4][5]
Founded in 2014 and based in San Francisco, California, Stampery emerged from the early blockchain wave to disrupt traditional notarization with Bitcoin's immutable ledger.[1][4] Co-founder and CEO Daniele Levi envisioned replacing notaries by generating legally binding proofs for sensitive documents, allowing users to certify via email, website, API, or Dropbox—proving existence and integrity without a centralized database.[4] The idea gained traction quickly: by 2015, Stampery launched at TechCrunch Disrupt SF, emphasizing verifiable proofs anyone could check at zero cost, even if the company vanished.[4] Early pivots included BTA technology (patent-pending at the time), enabling industrial-scale anchoring on Bitcoin and Ethereum, with a granted patent in 2018 for data certification systems.[1][2] While direct founder backgrounds beyond Levi are sparse, the company's GitHub activity shows technical depth in tools like MongoDB auditing (mongoaudit) and Elixir-based Merkle trees, reflecting a hacker ethos in blockchain and cryptography.[5]
Stampery rides the enterprise blockchain trend, applying crypto primitives to real-world needs like supply chain traceability, compliance, and e-discovery amid rising data integrity demands.[1][3] Timing was ideal post-2014 Bitcoin maturity, preempting regulations like GDPR and growing IoT/M2M ecosystems where trustless verification cuts friction in auditing and liability-prone back offices.[2][3][4] Market forces favoring it include blockchain's shift from speculation to infrastructure (e.g., Web3, DeFi enablers) and notary inefficiencies, positioning Stampery to influence ecosystems by enabling transparent, machine-verifiable records—potentially transforming legal tech and logistics.[1][3][6] Its open-source contributions (e.g., Mongoaudit) and patents amplify developer adoption in blockchain analysis and security.[1][5]
Stampery is poised to expand BTA into high-volume sectors like IoT supply chains and AI data provenance, capitalizing on maturing layer-2 scaling and regulatory nods to blockchain evidence. Trends like decentralized identity and zero-knowledge proofs will boost its proofs' adoption, evolving its role from notary-killer to core infrastructure for accountable AI and global trade. As blockchain integrates deeper into enterprise stacks, Stampery's privacy-preserving scale could cement it as the go-to for immutable data layers—humanizing tech by making "trust" obsolete through math, just as Daniele Levi first disrupted the notary line.[2][4]
Stampery has raised $600K across 1 funding round. Most recently, it raised $600K Seed in November 2015.
