Custom app and software development
Custom apps and software, built to ship and easy to own.
Web apps, mobile apps, customer portals, internal tools and integrations, with AI built in where it helps. Senior-led design and engineering, a working demo every two weeks, and code, accounts and documentation in your name from day one.
Why it matters now
A lot of businesses run on a spreadsheet, a shared inbox and a few people who know how it all works. A small, well-built app can replace that: a customer portal, a quoting tool, an intake workflow, a field app for your team.
We build on modern, widely used tools (React and Next.js, React Native, Node and Python, Postgres) so any good developer can maintain it after us. We start small, ship something real in weeks, and grow it from what users actually do.
And because AI is now part of most software, we know where it belongs in an app and where it doesn't, and how to keep its costs predictable.

How it runs
Scope
A discovery workshop, user flows and a written scope with what's in version one.
Prototype
A clickable prototype to test with real users before code is written.
Build in sprints
Two-week sprints with a working demo at the end of each. Change direction cheaply.
Launch and hand over
App store or web launch, monitoring, documentation and 30 days of warranty support.
What you get in hand
- Written scope and prototype
- Source code in your repository
- Deployed app in your hosting accounts
- Automated tests and monitoring
- Documentation and recorded walkthrough
What we've built
Real work, described without client names.
AI training coach
A mobile web app that builds personalized training plans with a small, fast language model, kept affordable enough to run for a growing base of real users.
Photo-to-listing agent
Identifies an item from a photo, estimates resale value and drafts marketplace listings automatically.
Assistant connectors
Servers that let AI assistants read and write data in outside platforms through the Model Context Protocol.
Summit Score
The free AI and search readiness grader on this site: a serverless app that fetches, parses and scores websites in seconds.

|---|---|---|
| App idea call | $450 | 60 minutes on your idea, options (build, buy, no-code) and a rough budget. |
| Prototype | from $7,500 | Clickable prototype tested with users, plus a written build plan. |
| Web app or internal tool (version one) | $25,000 to $60,000 | Typical first release, fixed price after scoping. |
| Mobile app (iOS and Android) | $40,000 to $90,000 | Cross-platform first release, fixed price after scoping. |
| Implementation sprint | $7,500 / 2 weeks | About 30 hours of senior-led build work for ongoing features. |
Common questions
Should we build or buy?
Buy when good software already does 80% of what you need. Build when the workflow is how you win, or when you're stitching five tools together with spreadsheets. We'll tell you which, honestly.
What about no-code and AI app builders?
Great for prototypes and simple internal tools. We often start there. Apps with real customers, payments or sensitive data usually need proper engineering, and we'll show you where that line is.
Do we own the code?
Yes. It lives in your repository and your hosting accounts from day one.
How long does a first version take?
Usually 6 to 12 weeks for a web app and 10 to 16 weeks for a mobile app, depending on scope and integrations.
Can you work with our developers?
Yes. We can lead architecture and AI features while your team builds, or hand over to them with documentation and pairing sessions.
