Provably enables AI, databases, and blockchains to create and exchange verifiable data. We believe systems shouldn’t just prove who sent the data, but that the data itself is correct and complete.
Our technology enables trustless data exchange for AI with reliable, error-free responses, programmable compliance for blockchain infrastructure, analytics and reporting on private data, and more. We are a European team of engineers and researchers specializing in cryptography and distributed systems.
Our work is grounded in formal cryptographic research. We developed QEDB, a modular architecture that enables expressive verifiable SQL without the overhead or complexity of SNARKs.

SourceryKit is a Python SDK that gives agents tools to build accurate and reliable workflows in minutes. Agents can verify their own work and each other's handoffs at runtime across APIs, databases, MCP servers, and backend tools.
-
Runtime Verification: Verify tool calls, API responses, database results, and MCP handoffs while the agent is working.
-
Verifiable Handoffs and Guardrails: Agents can prove and verify that content came from a source system, so errors can be caught and healed before they propagate.
-
Fast Setup: Add accuracy and reliability without weeks of observability and eval pipeline setup.
Our core solution for end-to-end data integrity. Provably V2 allows you to connect existing relational databases and transform them into verifiable data sources with millisecond latency.
- SQL IDE: Execute complex queries through a managed interface that generates cryptographic proofs of correctness automatically.
- Database Connectors: Seamlessly link your existing infrastructure to the Provably network without migrating your entire data stack.
- Proofs: Every query result is bundled with a proof that the data is both correct (not tampered with) and complete (no records were omitted).
