A practice of ESPO Engineering · Since 1965

Custody is the first question in healthcare software, and the industry answers it badly: your data in a vendor's cloud, your workflows behind a vendor's renewal. Every system we deliver runs on machines your organization controls, sealed to a master key only you hold — no escrow, no vendor copy. Who can change what is decided by the system itself, not a policy memo, and every change is a permanent, named entry. When the engagement ends, we delete our access. The platform doesn't notice.

Everything inside your walls.

Records, documents, tools, and the systems that build them run on machines your organization controls. The master key is minted on your hardware during the install, and there is no second copy anywhere.

One optional outside connection in the entire platform.

Who can change what is a property of the system.

Operations staff direct the work and can pause the AI at any moment — the machinery itself refuses anything beyond their role. Proposing, approving, and viewing are separate permissions, for people and AI alike.

Every change walks the same six steps, and the approver is never the proposer.

Undo is one step — and it goes on the record too.

Your staff describe the tool. The platform builds it, supervised.

A department manager writes a request in plain language. The build crew delivers a private working copy to approve, and an independent inspector attacks it before anything goes live.

AI works on temporary badges that expire in hours — master keys never reach it.

ESPO has engineered for organizations whose systems cannot fail since 1965. This practice brings that discipline to healthcare software.

Every system ships with its evidence.

Delivered as documents your review team can read on day one — and verifiable against the platform's public source, not against our word.

What arrivesWhat it answers
Complete access and change recordwho did what, and who approved it — including refused attempts
Written, enforced safety ruleswhat is allowed to run, and why
Attributed builds and releaseswhat is running right now, and where it came from
Key custody and recovery runbookswho holds the keys, and what happens if they're lost
Automated rebuild rehearsalswhether continuity actually works — exercised, not filed

Two ways to engage.

Implementations

Scoped per project and deployed inside your environment — weeks, not quarters. We verify the platform end to end, hand over the only key, and delete our access. It arrives whole, and it runs without us.

Development

Senior hours at $250 an hour — rolling, for steady counsel, or batched for a defined build. Nothing renews on its own, and any team you choose can pick up where we leave off.

Every engagement is structured so you can walk away with everything — the code, the keys, the knowledge. That is precisely why clients stay.

Tell us what you run, and what you'd rather own.

Plain language is exactly right — the workflows you have, the teams involved, the tool you wish existed. Your note goes straight to the practice, and a person replies within one business day.

Optional.

The workflows you run, what you want to own, and what's prompting the move.
