Software that respects the people who use it.
Interop Alliance designs and builds systems on open standards, decentralized identity, and bring-your-own-everything architectures -- for teams that treat data sovereignty as a product feature, not a footnote.
What we take on, and how we work.
Architecture and standards review
Audits of identity, data, and interop layers against open specs -- W3C DIDs, VCs, Authentication, Authorization, ActivityPub, and the RFCs that matter to your stack.
Decentralized identity systems
Production implementations of self-sovereign identity, verifiable credentials, and key-management flows that hold up under real users and real regulation.
BYO-everything platforms
Products built so your customers can bring their own storage, identity, permissions, and compute -- without rebuilding the app around each variation.
Privacy-first product builds
Small, senior engagements that ship real code: from protocol design to web and mobile clients, with privacy baked into the seams, not bolted on.
Five commitments we won't bend on.
-
The user is the customer.
Not the product, not the data source, not the growth lever. If a design choice can't be explained plainly to the person using it, we don't ship it.
-
Open standards.
We build on published specifications with interoperable implementations. If a standard doesn't exist yet, we contribute to one, publicly and in the open.
-
Identity belongs to the person.
Decentralized identifiers, verifiable credentials, and user controlled wallets. The alternative is renting your users back to yourself from a third party.
-
Bring your own everything.
Storage, identity provider, access control, compute. Software should adapt to where people already are.
-
Data minimalism as default.
Collect less, retain shorter, encrypt at rest and in transit. The safest database is the one that was never written to.
“Interoperability is a promise you make to your users -- that they can leave, take their things, and still be themselves.”
Have a system worth building carefully?
We take on a small number of engagements each year. If you're a founder, CTO, or engineering lead working on something where privacy, identity, or interop aren't negotiable -- we'd like to hear from you.
A first conversation is an hour, unpaid, and no pitch deck required.
