Sovereignty as a service

Yaya Tech: secure tech.

Yaya Tech makes your software provably secure and fully yours. Every piece of hardware, software, vendor and person that could read your data, or change what your systems do, is part of your trusted computing base (TCB). We shrink it to the minimum, and we prove what's left with cryptography instead of promises.

We're based in Palo Alto, California, and we work with teams worldwide, remotely or on site.

What we do

ServiceWhat you getStarts at
Audit what you haveA map of who can read your data today, what's exploitable, and a fixed-price plan to fix it$2,900 (Launch Audit, 5 business days)
Build what pains you mostSoftware we design and build for you. You own the code, the IP and the keys.$9,500 per build week
GPUs, hardware and colocationThe right hardware, the right deployment, the right budget. We source the GPUs and colocate them where your data has to live.$4,900 hardware and deployment plan
Managed deploymentsWe run it for you on your premises, in your cloud or in confidential capacity. You keep the root keys and can leave anytime.$2,500 / month

Everything we build or run ships with two things most vendors can't give you:

  • Cryptographic proof of secure execution. Remote attestation lets you verify which code is running, on what hardware, before any data reaches it.
  • Immutable logs. Every action is recorded in a tamper-evident, append-only log that you, your auditor or your regulator can verify independently.

Who it's for

  • Vibecoded startups. You shipped fast with AI coding tools. We find what's exposed, fix it and get you through your first enterprise security review.
  • Biotech and life sciences. Put AI to work on sequences, assays, lab notebooks and trial data without handing them to a model provider. Part 11-grade audit trails come built in.
  • Enterprise. Big business, big problem: our team of security experts takes it on, from incident to a smaller, provable TCB.
  • Businesses with cybersecurity needs. Fintech, health, legal, public sector, industrial and family offices: data residency, IP protection and evidence your regulator accepts.

How we work

  1. Book a free 30-minute call. We learn your stack, your data and your constraints.
  2. Audit. Fixed price and fixed timeline. You get findings, a TCB map and a quoted roadmap.
  3. Plan the hardware. The right GPUs and deployment for your needs and budget, then sourcing and colocation if you want them.
  4. Build. Fixed-price sprints with a working delivery every week. The audit fee is credited toward the build.
  5. Run it or own it. We operate it for you, or hand over everything you need to run it yourself.
