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.

Every request — a new form, a reminder, a whole module — travels the same five stages, each with a concrete guarantee. Watch one go through.

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 for how you work, on the same modern stack large companies use, and it keeps improving after launch.

A platform we built, not bought

Pyxeon's build pipeline is our own — designed by our engineers and run for every customer. That ownership is why we can ship a change in hours, fix things fast, and show you exactly what happened at every step.

Every change moves through the same gates: plan → build → tests → independent review → sign-off

ACAccounting firm · client portalsecure

Shaped to one business — yours

The same platform underneath, a different app on top. An accounting firm gets a client portal with e-sign and document sorting; a law firm gets intake and a document vault; a practice gets patient forms and reminders; a sales team gets prospect research and outreach that drafts itself. All on your own web address, with your own data.

Your own web address and your own database — never mixed with anyone else's
A built-in assistant that answers your clients' questions, in your voice
Hosting, security, backups and maintenance included

Customer story

Real businesses,
real apps.

Every business gets something different. Here are two that are live today.

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.

Steve stopped researching companies one at a time.

Steven Widom runs Widom Associates, an Autodesk system integrator that sells CAD/CAM software to woodworking manufacturers across the US and Canada. Finding the right shops, the right person at each one, and the software they already ran used to be weeks of manual research.

Problem

Hundreds of prospects to find, qualify and reach — by hand, one Google search at a time.

Built

A research and outreach tool that finds companies, locates the right contact, drafts personalized emails he reviews before sending, and tracks replies.

Now

A ranked list of thousands of companies with named contacts, outreach that drafts itself, and replies sorted by tone.

"Now the tool builds the list, finds the engineering managers, and writes the first email — I just review and send."— Steven Widom, Widom Associates

Questions

Straight answers.

The things people ask on the first call.

What happens if the AI gets something wrong?

It can't quietly reach your business. Nothing is built until you approve a written plan. Every change then runs through automated tests, is reviewed by a second, independent AI against the plan you approved, and is signed off by a Pyxeon engineer before it goes live. Still don't like it? One click puts things back exactly as they were.

Do I need to be technical?

No. You describe what you want in plain English and we handle design, engineering, testing and deployment. Your only job is to approve the plan in your portal — and tell us when something could work better.

How fast is the first version? How fast are changes?

A first version usually takes weeks, not months, depending on scope. Once your app exists, a request comes back with a written plan in minutes; after you approve it, the build, tests and review typically finish the same day. Bigger changes take longer — the plan tells you up front.

Is my clients' data safe?

Each business runs as its own separate app with its own database — your data is never mixed with anyone else's. Every change goes through the pipeline above before it touches your app, every deploy is backed up and reversible, and a health check watches your app around the clock.

What counts as an "update"?

One request in plain English: a new form, a reminder that sends itself, a report, a new screen. Bigger asks get split into a few plans you approve one at a time. Starter includes three a month, Growth ten, Pro unlimited — and every one is implemented, not just scoped.

Who owns the app?

One & Done builds include the source code from day one. Subscription apps are hosted and run by us so you never think about servers; if you ever want the code handed over, talk to us and we'll work it out.

Why not just use an off-the-shelf tool?

If a template fits your business, use it. Most people we talk to have already tried three, and each one made them bend their day around the software. We build around the way you already work — and keep building as it changes. Tell us how yours works.
