A real engineering department — for hire

Your AI Department. Hire it. Don't license it.

We don't sell you software and wish you luck. You get a real engineering team — senior engineers with deep enterprise AI experience — paired with a proprietary build pipeline that ships custom AI apps for how your business actually works.

How we work

Six specialists.
One subscription.

Engineering, design, security, AI and DevOps — the team you'd otherwise hire, vet and manage, running as one department from day one.

from $299/mo

A senior team like this runs $500k+ a year to hire and manage. We run it for you — from $299/mo.

The process

Three jobs. One department.
Build → Manage → Improve.

No black box, no template with your logo slapped on. We design the system, our pipeline builds it, and we keep improving it while you run your business.

01 / Build // architect + ship

We design and build it

Our engineers design the data model, the AI layer and the integrations — decades of combined ML and enterprise experience — then our proprietary build infrastructure turns that plan into a working app.

02 / Manage // host + maintain

We host and run it

Hosting, maintenance, security and uptime are handled. You get an online portal and a built-in AI assistant — no servers to babysit, no devops to hire. It just works.

03 / Improve // iterate forever

We keep improving it

Every month you get real feature updates — fully implemented, not just scoped. Your app keeps growing with your business instead of going stale the moment it launches.

See the pipeline that does it
The moat

The Pyxeon pipeline.

A proprietary build infrastructure we designed ourselves — every feature request flows through five stages, each with a concrete guarantee. This is the thing no competitor can template.

stage 01

Discover

We talk to you and map exactly how your business actually works.

stage 02

Architect

Engineers choose the stack and data model. A clear plan, not a black box.

stage 03

Build

Our AI build infrastructure turns the plan into real, working code.

stage 04

Validate

Tested + backed up + reversible. Nothing ships unchecked.

stage 05

Integrate

Deployed to your domain and woven into your day-to-day workflow.

Every change is tested, backed up and reversible before it touches your business.
Why Pyxeon

Not a template.
A real application.

Most small-business software is a template with your logo on it — you outgrow it in a year. Yours is built on the same enterprise-grade stack that powers Fortune 500 tools.

A platform we own end-to-end

We didn't buy our build infrastructure off a shelf — we designed and built Pyxeon's entire AI platform from the ground up. That ownership is why we can ship fast, fix fast, and never hand you a black box.

  • Proprietary AI build pipeline, not a no-code wrapper
  • React, FastAPI, managed Postgres + a custom AI layer

Real code, real pull requests

Every update is a real engineering change — written, tested and reviewed — not a setting toggled in some dashboard. You can see exactly what shipped and when, with a record you actually own.

Built for how you actually work

A CPA client portal, a law-firm document vault, a medical-practice intake system — every Pyxeon app is shaped to one business, with a built-in AI assistant that handles the questions you'd otherwise answer by hand.

  • Deployed to your own subdomain
  • Built-in AI assistant for your customers
  • Hosting, security and maintenance included
Customer story

One deep, real story
beats ten logos.

Amy Vlahos, EA amy.pyxeon.com
"Pyxeon built my entire client intake app end-to-end. What would have cost me tens of thousands in developer fees — and probably never would have gotten built — was live in a few weeks."
Problem

Clients emailing tax docs, no secure portal, hours lost to manual back-and-forth.

Built

A secure portal to upload documents, sign forms and pay online — plus an AI assistant that answers client questions automatically.

Result

Live in weeks, huge time and money saved, and her clients love how easy it is.

The part no one
can template.
