The Trust Layer for the Autonomous Economy

AI can spiral.
We make it provable.

Safety and security are the most critical questions in AI today. Prufold turns every AI decision into verifiable evidence you can show regulators, auditors, and your board — and we build it for you, and with you.

01 What we enable

Three surfaces, one cryptographic substrate.

One trust layer, composable across the stacks your teams already ship. No rewrites. No cryptography team required. The descriptions below adapt to the lens you chose above.

// 01

AI Safety

Cryptographic guarantees for agent and model behavior — controls you can prove, not just policies you hope hold.

Architectural enforcement →
// 02

Privacy-Preserving

Prove correct handling of sensitive inputs without ever exposing them. Zero-knowledge by construction.

Prove without revealing →
// 03

Reproducible Science

A tamper-evident record of every computation, ready for incident response and audit.

Proofs that travel →
02 The trust pipeline

From execution to proof, in milliseconds.

Follow a single request end-to-end. Your code runs as it always has — Prufold captures, folds, and proves it, so anyone can verify what happened without re-running it.

Step 01

Execute

Agent, LLM pipeline, or robotics workflow runs unchanged.

model.run()
Step 02

Trace

A structured record of the computation is captured.

trace → 0x7f4a…
Step 03

Fold

Zero-knowledge fold compresses it to a commitment.

commit(π)
Step 04

Prove

A succinct proof π is emitted — typically a few kB.

π · 3.4 kB
Step 05

Verify

Regulators, customers, or auditors check it instantly.

Execute
Your model or agent runs exactly as it does today.
03 Why now

Four forces, converging.

01
Exponential AI capability
AI systems are rapidly approaching and surpassing human-level performance across domains. When models reason and act autonomously, probabilistic monitoring is no longer enough — trust has to be enforced architecturally.
02
Regulatory pressure
Governments worldwide are implementing AI governance frameworks that require verifiable safety and compliance. Audits demand evidence that scales — cryptographic proof is the only substrate that does.
03
The cost of AI failure
High-profile AI failures are costing billions and eroding trust, making reliability a competitive necessity. Every hallucinated output, silent drift, or unauthorized action carries a balance-sheet cost.
04
Inference is the new substrate
As inference becomes the dominant share of AI compute, verifying what that compute actually did becomes essential infrastructure — not a nice-to-have. Systems that cannot be proven safe will be replaced by systems that can.
04 Who it's for

One proof layer. Every stakeholder.

The same cryptographic evidence answers a different question for each person in the room — from the engineer shipping the agent to the board signing off on the risk.

CISO · Security
"Can I prove what our AI did under audit?"

Tamper-evident attestation for agent behavior, model provenance, and data handling — enforced by construction, ready for incident response.

CTO · Engineering
"Can my team adopt this without a rewrite?"

Drop-in verifiable execution for agentic apps, LLM pipelines, and robotics. Capture, fold, verify — exposed as a simple SDK, no ZK expertise needed.

Board · Risk
"Is our AI exposure something I can sign off on?"

Verifiable evidence you can show regulators, auditors, and the board — assurance backed by cryptography, not by trust in a vendor's word.

Researcher · Builder
"Can others reproduce and trust my results?"

Make every result independently checkable, with a proof that travels with it — so scientific and model claims hold up beyond your own lab.
