The axis other things
depend on.

Axion builds where mainstream tech stops caring. Branded apps for venues Square and Toast won't touch. Commission tools for payment dealers running spreadsheet hell every month. Protection for consumers who lose disputes because they had no proof. We have live deployments, real merchants, and real revenue on the Shift4 network. We're not pitching the idea — we're extending what already works.

Products

Five bets, one playbook.

Meet The Bull

Same villain.
Two fronts.

Rental companies and dishonest hosts run the same play — claim damage, charge the customer, count on no proof. The Bull is the mascot for both fights. Drop your email and we'll let you know the moment LotProof or NoBullStay opens to the public.

NoBullStay

Airbnb inspection protection — same Bull, different fight.

Arrival and departure condition documentation for vacation rentals. Photo evidence with timestamps, room-by-room walkthroughs, exportable reports for dispute resolution. Built because hosts banking on "you can't prove it wasn't like that when you arrived" is a business model, not an accident. Beta is shipping now — public launch expected Q2.

Working prototype

Medical Tricorder

Star Trek promised this. We're actually building it.

Sixty years ago, Roddenberry put a handheld diagnostic scanner in the hands of a country doctor on a starship and told a generation of kids the future could be kind. We grew up on that. Now most of us write software or fly rockets — almost no one went into medical hardware. So we did. This is a working prototype, not a prop. A handheld sensor array that pairs with any phone and brings clinical-grade signal interpretation outside the hospital walls. Vital signs. Preliminary screening. Triage in places where there isn't a doctor for a hundred miles. The future Trek promised wasn't optional. It's overdue.

Community Projects

Free tools for communities we care about. No ads, no tracking, no monetization.

Sammy's Dinos

Jurassic World Evolution 3 habitat compatibility planner. Pick a seed dinosaur, see compatible habitat mates ranked by environment and food overlap. Built for Sammy's love of dinosaurs and shared with the JW3 player community.

The name

Axion is the axis.
Built is the standard.

Two words. Both deliberate.

Axion

The center point something rotates around.

Infrastructure. Foundation. The thing that holds everything else up. We're not building experiments — we're building the axis other things depend on.

Built, not Labs

Labs explore possibilities. Built delivers certainties.

Labs test. Labs prototype. Labs publish papers. We ship. "Built" is past tense — finished, deployed, in production, people using it right now. The standard isn't "it works in our environment." It's "it works in yours."

The through-line isn't the technology. It's who gets left out when everyone else stops caring. We pick one vertical, build the whole thing, and ship it. Then we put our name on it.

— Built by Axion

Why Axion

Infrastructure for people,
not platforms.

Small team. Real customers. Tools that shift power back to the human in the transaction. Where our products use AI, it's there to help you — never to replace the person on the other end of the call.

Consumer protection, always

Rental companies and dishonest hosts bank on information asymmetry. LotProof and NoBullStay build the evidence layer that levels the field. Protection isn't a feature — it's the point.

People first, tech second

A small team shows up on the other side of every product we ship. The tools we use — including AI — exist to give individuals capabilities they couldn't reach alone: clinical-grade sensing, instant evidence, commission math that's actually right. The tech serves the human. Always that way around.

Accessibility, not gatekeeping

Medical diagnostics shouldn't require a hospital visit. Venue management shouldn't require an enterprise budget. Good software scales down to the person who needs it, not just up to the customer who can pay the most.

Community over commerce

Some things we build because they should exist, not because they'll hit a quarterly target. Those projects stay free, ad-free, and tracker-free. The receipts on those live under Community Projects below.

Partnership

Built on Shift4.
Extended by Axion.

Axion Built is an authorized Shift4 / SkyTab partner. Every product we build that touches payments runs on the Shift4 network — not around it. TrussTab extends SkyTab OLO into branded mobile apps for venues that couldn't get approved elsewhere. ResidualPro gives Shift4 dealers commission clarity they've never had from any other tool. We're applying for expanded API access to deepen these integrations — loyalty sync, customer authentication tokens, and real-time menu management.
