What we do

Software and AI, built around how your business actually works.

You bring an idea or a rough problem. We turn it into a real product, with the web app, the mobile app, the AI, and the design all handled by one team.

Custom SaaS & Web Apps

The software your business runs on. Dashboards, customer portals, booking systems, marketplaces, whatever your team actually needs to get through the day.

  • Web apps and dashboards
  • Customer portals
  • Built to grow with you

AI Integration

We bring AI into your business in a way that earns its keep. Assistants that answer questions, automations that handle the busywork, agents that do real jobs.

  • Chat and assistants
  • Workflow automation
  • Custom AI agents

Mobile Apps

iOS apps your customers will want to open. We take it from the first sketch all the way to a live listing on the App Store.

  • iOS and mobile

  • Simple, clear design

Design & Branding

A look that makes any team feel established. Logos, brand, and interfaces that are easy on the eye and easy to use.

Our work

Apps we have built for our clients.

Every project here was designed and built by us for a customer. Different industries, one idea in common: take a good concept and ship it as software people enjoy using.

AncestryScan

See your heritage from a single photo.

We built AncestryScan to read ancestry from one photo in under a minute. It studies facial features, matches them to regions around the world, and hands back a clean visual report worth sharing. It all happens privately on the phone.

StudioShots

Studio photos of your kids from one picture.

A photo app for parents. Upload one picture and StudioShots turns it into themed studio portraits, from superheroes to safari shoots, while keeping the child's real face. We made it simple enough for a tired parent and safe enough for a kid's photo.

TEN45

Ten squats, every forty five minutes.

A movement reminder for people who sit all day. It nudges you to do ten squats every forty five minutes, logs it, then goes quiet. One habit, no feed, no coaching, nothing to set up.

Guardia

Maintenance that runs on the clock.

A marketplace for building and HOA maintenance. Small fixes get matched to a contractor in minutes. Bigger jobs go out to a sealed bid over a day or two, scored on more than just price. Every job runs on a timer so nothing slips.

Why Paradox

What it is like to work with us.

We work with a select group of clients at a time, so every project gets senior attention from the first sketch through to launch.

01

Built for you, not us

Every app on this page was custom built for a client. You own the product and the code. We are the team that designs it, builds it, and gets it live.

02

One team, start to finish

You work directly with the senior team that designs and builds your product, not a chain of account managers. Design, engineering, and AI all sit under one roof.

03

You see progress every week

We get a working version into your hands early and shape it with you from there. No black box, no big reveal at the end that misses the point.
