Founder-led sprints & custom pilots

If you sell agents into finance, healthcare, or government, procurement asks "prove what your agent actually did." Logs don't survive that question. A sealed .epi does: every run ships with an Ed25519-signed evidence file — hash-chained on the SDK path, manifest-declared on the gateway path — your customer's auditor verifies offline, with open tools. The evidence outlives your contract with them.

Open Source

Free forever · MIT

Verification will never cost money. That's the point.

Before you buy anything: read KNOWN_LIMITATIONS.md — the seal proves integrity after sealing, not completeness of capture.

Straight answers

Why is verification free forever?

Cryptographic evidence only works if it's trustless. If you had to pay EPI Labs to verify your own files, it wouldn't be trustless. The CLI is MIT-licensed. That's the spine of the company.

What do I get in a $1,500 sprint?

Five focused days with the founder: one agent workflow instrumented end-to-end, sealed artifacts your team can re-verify offline, and a short findings report. Priced against unblocking enterprise deals — not billable hours.

Is there a free trial?

No trial — you are charged at checkout. Cancel anytime with one click in your account portal; Paddle handles pro-rated refunds per their Merchant of Record terms.

What is a design partner pilot?

Someone whose needs go beyond standard tiers — org keys, hosted receipts, remote SCITT anchoring, or special procurement requirements. Founding pricing, direct roadmap input, engagements from $5K.

How working together works

01 · Talk

A 30-minute call — or just email. You describe the agent workflow and who needs to be convinced (auditor, insurer, regulator). We say honestly whether EPI fits. If it doesn't, we'll tell you.

02 · Pilot or sprint

Either a $1,500 sprint (one workflow instrumented in five days, sealed evidence you keep) or a $5K design-partner pilot (org keys, hosted receipts, direct roadmap input). Fixed scope, fixed price, no procurement maze.

03 · Prove it internally

Your team verifies everything offline with open tools — no dashboard login, no vendor trust required. If your auditor can't reproduce it, we haven't finished the job.

04 · Scale

Design partners move to the Control Plane with founding pricing locked. You shaped it; you keep the terms.
