# Software built around how you work.

When off-the-shelf tools don’t fit, we build custom ones that do, and connect them to the software you keep. Our engineers build inside your business, and you own the code.

## Built for the IT review.

### You own it

Code, accounts and data live in your accounts. Nothing is held hostage.

### Secure by default

Credentials stay in your systems or ours, never on personal devices, and access is removed the day work ends.

### No training on your data

We only use AI tools under terms that don’t train on what we put in.

### Built to hand off

Documented as we go, so your team or ours can run it.

## Clear before we start.

Custom build

$100k to $250k

Fixed scope and price, agreed after the scoping call.

After launch

Monthly

Optional support, updates and new features. Cancel anytime.

## Questions buyers ask us.

### Why not just buy off-the-shelf software?

If it fits, you should. We build when you’re paying for features you don’t use, stitching tools together by hand, or bending your process to fit the software.

### What does it cost?

Most builds run $100k to $250k, with a fixed scope and price agreed after the scoping call.

### Who owns the code?

You do. It lives in your accounts from day one.

### Will it work with our other systems?

Yes. We connect to the tools you keep, and move your data out of the ones you retire.

### What happens after launch?

Keep us on for monthly support, or hand it to your own team. Either way it’s documented.

### Can we start small?

Yes. Many partners start with one workflow, then replace more once it’s working.
