Custom software, built to order

We build small, custom software tools for individuals, professionals, and business owners: people like the dentist whose front desk rebuilds the same list every Monday, the contractor quoting jobs from a coil notebook, or the executor tracking an estate across three spreadsheets (see the illustrative example builds). Specific pain points, focused tools, built to fit the software and habits you already have.

You never have to adopt a new platform, migrate your business, or retrain your team. We build around your existing workflow, so the tool works for you immediately.

What we build

What we don't build: mobile apps, medical devices, e-commerce platforms, or anything that puts patient or client health records in the cloud. If your project isn't a fit, we tell you at discovery, honestly and early.

Buy it, or lease it

If you stop payingNothing changes; it's yoursAccess ends at the period's end
Your dataAlways on your machineAlways yours; exported on request

Three commitments protect every lease: your data is exported to you on request within 14 days of cancelling; prices never change without 30 days' written notice; and if we ever discontinue a tool, you get at least 60 days' notice plus your data, and where practical a one-time buyout option. Leasing from a small studio should not feel like a leap of faith.

What it costs

One-time builds start around $500; monthly leases start around $49 per month. The price reflects what the tool is worth to you and the work involved in building it, and it is fixed in writing before we start. Compare that against the off-the-shelf subscription you'd pay every month and mostly not use: a focused tool that fits exactly is usually the cheaper option within the first year.

And if something off the shelf already solves your problem well, we tell you that at discovery and point you to it. It costs you nothing to find out.

How an engagement works

  1. Tell us the problem.

    Fill out the form. Describe the pain points in your own words: what you're doing today, what you've tried, what keeps going wrong.

  2. Discovery.

    We come back with questions until we understand the problem completely: your current software, your files, who'll use the tool, what it must do. This is also where we research whether existing software already solves it. If it does, we say so and point you there instead.

  3. A fixed quote, in writing.

    One page: what the tool will do, what it costs (one-time, monthly, or both), and when you'll have it. You accept by replying. The price never moves after that.

  4. We build it.

    Designed around your workflow from day one: simple screens, no unnecessary complexity, nothing you'll have to learn twice.

  5. We test it, hard.

    Every part of the tool is checked, fixed, and re-checked until repeated rounds of testing come back clean. Polish is part of the price, not an extra.

  6. You see it working, then you pay.

    We demo the finished tool doing your job with your kind of data. If it does what the quote promised, you pay and we hand it over (or switch on your access). For 30 days after delivery, any defect gets fixed free.

Common questions

Who owns the software?

If you buy a build outright, it's yours: you get the software and the right to use it and keep it forever. We keep the right to reuse generic building blocks (code that isn't specific to you or your data) in other projects. If you lease, we own and run the tool and you subscribe to it; the data inside it is always yours.

What if I don't like it?

You see the finished tool working in a demo before you pay anything. If it doesn't do what we agreed in the quote, you don't pay, and we either fix it or part ways.

Do I need to be technical?

No. We assume you're not; that's who we build for. If you can describe the problem in your own words, that's all we need to get started.

Will Windows warn me about the installer?

For desktop tools, Windows may show a "Windows protected your PC" notice the first time you run a new installer. That warning appears for any new app that hasn't yet built a reputation with Microsoft, including ours. Click "More info", then "Run anyway". We'll walk you through it at delivery.

How do updates work after a one-time purchase?

For 30 days after delivery we fix any defect free. After that, the tool keeps working as delivered; if you want ongoing updates and priority help, purchased builds can include an optional yearly support plan, priced in your quote. Leased tools always include updates and support.

What happens to a leased tool if you shut down?

If we ever discontinue a leased tool or wind down, you get at least 60 days' notice, a full export of your data, and where practical a one-time buyout option so you can keep running it yourself.

How long does a build take?

It depends on scope. Small tools often take days; larger ones take weeks. Your quote includes a delivery estimate, and we tell you promptly if anything changes it.

What don't you build?

Mobile apps, medical devices, e-commerce platforms, and anything that requires storing patient or client health records in the cloud. If your project isn't a fit, we say so at discovery, and where we can, we point you at a better option.

The next step costs nothing: describe your pain points and we'll tell you honestly whether a custom build makes sense. We reply within 2 business days.
