About epyx.ai
A physicist who spent a career in semiconductors, building the document he kept needing and could never buy.
James Flowers
Founder, epyx.ai
MS in Physics from Caltech, BA in Physics and Mathematics from Rice. Founder of Palma Ceia SemiDesign, CEO of Clarisay. Sole inventor and author of the epyx patent application filed in April 2026 — and, two decades earlier, named inventor on roughly ten patents covering surface-acoustic-wave filter technology and the software behind it.
How this problem found me
Chip design is the most unforgiving software domain there is. The users are experts, the tolerances are absolute, and the cost of being wrong is a fabrication run. I spent decades there — filters, radios, design enablement — and watched the same thing happen in every one of them.
The person who understands the problem is almost never the person who can build the tool. So the engineer who knows the physics ends up fighting a scripting language instead of doing physics, or waiting on someone who has never seen the problem. The work gets done in spreadsheets that nobody can trust and nobody can share.
epyx is that problem, solved generally. Not a better spreadsheet, and not another way to generate code nobody can read — a document that computes, that the person with the question can build for themselves.
Track record
- 2012 – 2023Palma Ceia SemiDesign — FounderWi-Fi HaLow silicon for IoT. Just under eleven years.
- 2001 – 2004Clarisay, Inc. — CEOSurface-acoustic-wave filters — the devices behind the patents.
- early 1990sInstinct Software — FounderOne of two prior software ventures.
- since 1989Logix Consulting, Inc. — CEOChip design and design-enablement work, across decades.
Two prior software ventures. One had modest commercial success; neither is a name you would recognise.
The team
Two people: the founder above, and a CFO.
Jim Shaw
CFO
A CPA and past director at Lain, Faulkner & Co., with over forty years of tax and audit experience across public practice and banking. Previously a senior partner for more than twenty-three years at Litzler, Segner, Shaw & McKenney, where he oversaw all tax and compliance filings for a firm that handled thousands of bankruptcy cases and numerous court appointments. Earlier, partner in charge of a regional accounting firm's Dallas office, internal auditor at a national bank, and contracted to the FDIC.
B.B.A. magna cum laude, Midwestern State University. Certified Public Accountant licensed in Texas and a Chartered Global Management Accountant.
A CFO who has spent a career on bankruptcies, receiverships and court appointments is not a bookkeeper. He has spent forty years being called in after a company's finances have failed — which is a useful thing to have in the building from the first day rather than the last.
epyx was built by one person. That is not a footnote about our size — it is the product claim, demonstrated.
A system of this size used to require a team. It no longer does, and the thing you are being shown is the evidence. We would rather prove the thesis than describe it.
What we are building
The next generation of working tools should not require you to become a developer. epyx closes the gap between a spreadsheet and a real application — build it, share it, and keep it.
- •Local-first — your data stays on your devices
- •Editor-native — built for how you actually work
- •Doclet-centric — self-contained, shareable workspaces that never leave your computer
Foundational patent covering the doclet architecture — written and filed by the founder, April 2026.
