Custom Software

Most apps get their auth bolted on. Ours are designed around it.

Web and mobile applications, dashboards, and SaaS platforms with authentication, role-based access, billing, and reporting engineered from the first commit: built multi-tenant so scaling to your thousandth customer requires a signup, not a rebuild.

Capabilities

What We Build

01

Software People Log Into

  • Built so a thousand customers can share one system safely
  • Dashboards and admin screens for your team
  • Tools that take the manual steps out of a process
  • Screens that update the moment something changes
02

Phone Apps

  • iPhone and Android
  • One app that covers both, when that saves you money (React Native)
  • App-like sites that install without an app store
  • Keeps working with no signal, catches up when it returns
03

Connecting to Other Systems

  • Connections other software can plug into (REST and GraphQL APIs)
  • Hooking up the tools you already pay for
  • Taking payments and sending invoices
  • Things that happen automatically when something else does
04

Security Built In

  • Sign-in, with each person seeing only what their job allows
  • Covered against the ten most common web attacks (the OWASP Top 10)
  • The outside code we use is checked for known holes
  • We try to break in ourselves before you go live
Methodology

How We Engage

01

Discover

We map what it must do, who uses it, and where the data goes, and how someone could attack it.

02

Design

We plan how it is built, and how it looks and feels to use.

03

Build

We build it in small tested pieces, with security checks on every change.

04

Launch & Scale

We try to break in, put it live, watch it, and keep improving as you grow.

How We Use AI

We use AI to move faster on the build and the testing. Then we attack the result the same way we would attack any client's app, so what we ship has already survived us.

Human-led, AI-accelerated: every finding is validated by a certified expert.
FAQ

Frequently Asked Questions

What kinds of applications do you build?

Web platforms, software your customers subscribe to, internal tools, dashboards, phone apps, and the plumbing that connects them, from a first version to a system a whole business runs on.

What technologies do you use?

Mostly TypeScript with React, Next.js and React Native, modern cloud hosting, and whichever database suits the job. If a different set of tools fits your goals or your team better, we say so.

Is security really included?

Yes. Sign-in, who-can-see-what, checks on the outside code we use, cover for the OWASP Top 10 (the ten most common web attacks), and a penetration test before launch are part of every build, never an upsell.
