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 hallucination-free and poison-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.

A Python SDK that adds verifiable guardrails to any Python agent. AgentKit improves transparency and security at the process level by combining HTTP recording, claim validation, and endpoint policy enforcement.
- HTTP Recording: Every outbound call is recorded for auditability by the Provably interceptor.
- Claim Validation: Agent handoffs are evaluated by the Eval service as a verifiable guardrail against trusted Provably query records.
- Policy Enforcement: Enforce the "policy edge" by controlling which endpoints an agent can access before the request even leaves the process.

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).
