Custom tools for small businesses

Every business has
one thing
no app was built for.

We build the internal tool for that specific thing. Your app arrives ready, and we spend the session making it exactly right together. Fixed price from $599. The code is yours completely. Do you know what your thing is?

Sound familiar?

The thing that makes your business different isn't in any app.

It can't be — it's the thing that's uniquely yours. It's usually still in a spreadsheet or on paper, not because it's broken, but because nothing out there was built for exactly how you work.

Once we build the app for it, two things open up: you can take on more work, and you can finally see what's happening in your business.

✓Your data lives in emails, a spreadsheet, and someone's memory
✓Your no-code tool is hitting its limits - or its monthly fee keeps climbing
✓You need something on your phone, for your team, that works the way you do
✓You've tried explaining it to a developer and never heard back

The Koltevate difference

Custom software doesn't have to be complicated or costly.

We start with a conversation about the one thing no app covers. Then we build your app — ready for your session. We spend the afternoon refining it together until it's exactly right. You leave with a working app on your phone. We hand you the code outright. No subscription required. Every session is led by Andrew Higginbottom, a software architect with over two decades of experience across startups, enterprise, and government.

How it works

Three steps. One afternoon. Yours forever.

Every Koltevate engagement is built on clarity, listening, and a shared commitment to getting it exactly right.

We agree what we're building

You fill in a short intake form. We review it personally and send you a plain-English Build Plan - exactly what we're building and what's out of scope. No surprises. No jargon.

Andrew reviews every intake form personally — you're not going into a queue.

Your app arrives ready. We refine it together.

You see your working app for the first time at the start of your session. We spend the afternoon making it exactly right. If something doesn't feel right, we catch it on the day — not in a revision round three weeks later.

End of session: scan a QR code and your app is on your home screen, ready to use.

It's yours - completely

The code goes to your own GitHub repository. Zero operational costs to start. No subscription required. And when you need something added, we're just a message away.

The session is the beginning of the relationship, not the end of it.

What you get

Everything you need.
Nothing you don't.

Koltevate Build Sessions are grounded in one idea: you should know exactly what you're getting before we start.

◎

Fixed price. Fixed scope.

You know exactly what you're getting before we start. No surprise invoices. No scope creep. No renegotiating mid-session.

⬡

Refined together, in front of you.

Your app arrives ready. You're not handing over a brief and waiting weeks. We spend the session making it exactly right — and you catch anything that doesn't feel right on the day.

⚑

Yours completely.

The code goes to your own GitHub at the end of the session. No monthly fee can take it away. No platform lock-in. Just yours - forever.

◈

We're still here.

Most clients stay in touch through a simple monthly plan - one change or fix per month, starting at $49. No contract. Cancel any time.

From clients

They came with a problem.
They left with a tool.

The thing clients mention most isn't the technology - it's being genuinely heard.

"It's so good working with you cause you're really listening and then using all your talent to create something awesome. Love it."

Questions

A few things people ask.

Do I need to be technical?

Not at all. You bring the domain knowledge - how your business works, what's slowing you down. Koltevate brings the technical expertise. You don't need to understand how it's built, just that it works exactly the way you need it to.

What kind of tools can you build?

Internal operational dashboards, field data collection apps, intake forms, spreadsheet-to-app migrations, estimators and client calculators - anything that helps your team work faster and smarter. Koltevate Build Sessions aren't the right fit for building apps for re-sale, public marketplaces, payment gateways, or real-time social platforms.

What if I need more after the session?

The Build Session is the beginning of the relationship, not the end of it. Most clients come back for a Follow-on Session, join the Care Plan, or eventually take on a larger Growth Build. Everything moves at your pace.

What happens when my team grows?

Your app can start with zero operational costs. When your team needs shared access across devices, we migrate you to the cloud - that's a natural next step, not a surprise cost.

Do I really own the code?

Completely. At the end of the session, the code is delivered to you. No subscription required. No platform lock-in. It's yours as permanently as anything you've ever built yourself — except it does a lot more.
