Custom software development · Denver, Colorado
Custom software built around your business.
You know how your business should run. Off-the-shelf tools make you work around them. We build custom software that fits the way you already work: the app your customers use, the system your team runs on, or the idea you have been sketching for years. Nadwell AI is a custom software development studio in Denver, Colorado, and we have built more than 20 projects for our clients.
20+ projects deliveredMore than twenty custom software projects built and handed over to our clients.
Your own private sandboxEvery project is built in its own isolated space. Your code and data never mix with another client's.
A fixed quote firstScope and price are agreed piece by piece before you pay a deposit.

What we build
Custom software for every stage of your business.
Bring us an idea on a napkin or an app with ten years of history. An MVP, a custom web app, a mobile app or new features for the system you already run: the process is the same. We agree what matters, mock it, then build it in small pieces you can use as they land.
MVP
Get a first version in front of real users quickly. We cut the idea down to the core that proves it, then build that properly.
Good fitYou have an idea and need it working, not just pitched.
Greenfield
A new product built from a clean start, with the architecture, security and hosting it will need in year three.
Good fitYou are replacing spreadsheets or starting a new product line.
Brownfield & new features
New features added to the app you already run. We map the area we touch, test around it, and leave it better documented than we found it.
Good fitYour app works, but the backlog keeps growing.
Environment migration & build-out
Move from a single server to proper dev, staging and production, with automated deploys, backups and rollback.
Good fitReleases are manual and nobody wants to touch the server.
Scaling
Find what breaks under load and fix it: caching, queues, database tuning and autoscaling, proven with load tests.
Good fitYou have a busy season and your app slows down.
Data migration
Move data out of Access, spreadsheets or an old system into a cloud database, reconciled row by row before cut-over.
Good fitYour data lives in five places and none of them agree.
Private by design
Your project is built in its own private sandbox.
Every client project is developed in an isolated sandbox. Your code, your data and your ideas never mix with another client’s work, and what we show you is visible only to your team.
Its own repositoryYour code lives in a repository of its own, never shared with another client's project.
Its own environmentsThe test and preview environments we build in are set up for your project alone.
Its own accessYour progress report sits behind your own sign-in and opens only for the people on your team.
Sample data while we buildWe build and test against sample data, so your real customer records stay in your own systems.

The kind of projects we take on.
These are illustrative examples, written to show how the process fits different jobs. The businesses are fictional.
Mobile app
Summit Peak Plumbing & Heating
Twelve technicians worked from paper tickets and phone calls. Parts used on a job were often never billed, and the office could not see who was where.
Web app
Mile High Bakery Co.
About forty cafés ordered bread by text and voicemail. Orders arrived after the bakers' cut-off, and invoices were typed up by hand every Friday.
Scaling
Powder Day Rentals
The ski-rental booking app slowed to a crawl on Saturday mornings and on the first big snow of the season, exactly when bookings mattered most.
