Software development

Software built around how your business actually works.

We design, build and run web and mobile apps, and we use our own every day: a construction management system, a bookkeeping platform and an inventory app, all in production.

What we build

From the first sketch to the app store.

Business web apps

The system your team works in all day: estimates, schedules, approvals, documents and reports, with the permissions and audit trail a real business needs.

iPhone and Android apps

One codebase in both app stores, with offline work, the camera, barcode scanning and Face ID sign-in where they help.

Integrations

QuickBooks Online, Dropbox, city permit portals: data flowing between the tools you already pay for instead of retyped.

AI that works with your data

Assistants that read your records and draft changes for a person to approve (MCP connectors for Claude and others), or models that run on your own computer so nothing leaves the office.

BI Inventory on iPhone: a freezer’s contents with quantities and days until each item expires
Inventory · iPhone, Apple Watch, Web

BI Inventory

Stock and supplies across nested locations, scanned by barcode, with reorder alerts, expiration reminders and a history of who moved what. Nothing is ever deleted, just archived with a reason.

Web, iPhone and Android

One codebase on the web and in the app stores, with native features where they matter.

AI that stays in its lane

Assistants that read your data and draft changes for a person to approve, or models that run on your own computer.

Built to be trusted

Per-person permissions, passkeys and two-factor sign-in, audit logs and documents kept exactly as sent.
