Prototyping Sprint, $1,000 per week

See your idea working in one week, before you bet serious money on building it for real.

For $1,000 I'll build a working prototype of your app or internal tool in one week, with a well-designed frontend and a connected backend if it needs one, so you can click through it from a link, show it to the people who matter and decide what happens next.

If you're not happy with what you see at the demo, tell me and you don't pay for the week, and if you like it and want to take it further, another week is $1,000.

I bill one week at a time after the demo, and you own the code, so if one week gives you your answer, you're done.

Which one sounds like you?

I'm starting something

Before you quit your job, pitch an investor or sign an agency contract, click through the real thing.

You have an idea for an app-based business and a big decision coming up, whether that's leaving a salary, raising money or hiring someone to build it. A working prototype lets you put the idea in front of customers, partners or investors and watch what they do with it, instead of asking them to picture it from a slide.

Examples of a one-week scope: a booking or ordering app for the customers you already have, a marketplace that matches two sides of your industry, or a client portal you plan to charge for.

I run a business

Stop describing the tool you wish your team had, and put a working version in front of them next week.

Your team runs an important process on spreadsheets, email threads and a piece of software that almost fits, and there's usually one person who knows how to make it all work. A prototype shows everyone what the fix looks like before you spend budget on it or ask a development team to build it.

Examples of a one-week scope: a quoting tool that replaces the spreadsheet, a job-tracking dashboard pulled from the tools you already use, or an intake form that routes requests to the right person.

Most ideas get expensive long before anyone has used them.

Whether you're a founder or running a team, the missing piece is usually the same, and it's something you can hold up and say “look at this” instead of “imagine this.”

The agency quote

Here's how it usually goes for founders. You ask an agency to build your first version, the quote comes back in the tens of thousands of dollars with a timeline measured in months, and so you either stall or sign before anyone has touched the thing you're paying for.

The weekend build

The other road is building it yourself with one of the AI app builders, which gets you surprisingly far on a Saturday and then leaves you stuck for weeks of evenings on logins, real data and a design that looks like every other AI-built app.

The tool nobody can see

Inside a business it looks a little different, but the cost is the same. You've described the tool in three meetings, everyone nods, and nothing changes because nobody can see it yet, so the spreadsheet workaround quietly becomes permanent.

One week, one working prototype, and a decision at the end of it.

We can kick off on whatever day suits you, and the demo happens one week later.

  1. Kickoff

    We start by cutting your idea down to the one flow that proves it and agreeing on that scope together, because a focused week that ends with something working beats an ambitious week that ends half-built.

  2. Build

    I build it using AI tools plus years of engineering and product judgment about what to cut and how to wire things together, and because we agreed the scope at kickoff, you'll know exactly what you're going to see at the demo.

  3. Demo and handoff

    One week after kickoff we walk through the working prototype together, I record the walkthrough, and you get the demo link along with the code and a handoff note in your own GitHub.

If the idea needs more than a week, you'll see that clearly by the end of it, and you can decide whether another week is worth it.

Here's what's yours at the end of the week.

A working prototype with a demo link

It has a well-designed frontend you can click through, not a set of static screens, and it's hosted at a link you can share with customers, partners, investors or your team.

A connected backend if your idea needs one

Logins, saved data and the core logic behave the way the real thing would, so the people testing it are reacting to something that actually works.

The code in your own GitHub

Every line of it belongs to you, whether you build the next version with me, your own team or someone else.

A recorded walkthrough

It covers how the prototype works and why I built it the way I did, so you can share it with a partner, an investor or your team.

A handoff note for developers

It explains the structure, what's finished, what's stubbed out and what I'd build next, so whoever picks it up doesn't start from zero.

I don't deploy it to production or maintain it, and that's on purpose.

A prototype's job is to help you decide what to build, and the fastest way to waste money is to scale, secure and support something nobody has tested yet. So I keep the week focused on getting you a working version and a clear answer, and I leave production hosting and ongoing maintenance to the people who do that every day.

When you're ready for production, you have two good options. You can hand the code, the walkthrough and the developer note to your own team as a working spec, or I can recommend developers I trust to take it the rest of the way, and either way you're choosing a builder with something real in hand instead of a description.

This is a good fit if you're about to make a real decision.

It's a good fit if

  • You have an idea for an app-based business and you want to see it working before you commit your savings, your job or an investor's money to it.
  • You run a business or a team and you need to show people the tool before anyone approves a budget or a development project.
  • You tried building it yourself with an AI app builder and got stuck somewhere around the logins, the data or the design.
  • Your idea is in a field like finance or healthcare, which is fine for a sprint, because a prototype isn't the production system that has to meet those rules.
  • You're comfortable deciding at the end of each week whether the next one is worth it.

It's probably not a fit if

  • You need a finished product running in production next month, because this week ends with a prototype and a handoff rather than a launch.
  • You want someone to host and maintain the app long term, in which case read about working with me as a Founding Tech Partner instead.

Hey, I'm Austin.

I build software and AI systems for businesses, and I've worked with 20+ Nashville business owners to put that technology to work. Before HomeTeam I spent my career in engineering, data analysis and product management, which is the part that matters most in a one-week sprint, because the hard call is rarely how to code something and usually what to leave out.

I use the same AI tools you've heard about every day, and I'll be straight with you that they're a big reason a week is enough. What they can't do on their own is decide which flow proves your idea or how the backend should fit together, and that's the part you're paying me for.

I'm based in Middle Tennessee, and the sprint works the same wherever you are.

What people say about working with me.

"Austin stepped in with clarity and direction that genuinely changed the way I approach my work. He didn't just help refine my ideas — he helped turn them into a clear, actionable plan."

Gowen Cox, TapKeep

"Austin has a bias to action that cuts through the hype cycles and gets to, 'What can we do right now?' He can drop into any business problem and offer creative but practical solutions."

DJ Tosh, Entrepreneur/Business Owner

$1,000 for one week, and another week only if you want one.

$1,000 per week

A sprint is one week of building, starting on whatever day you choose and ending with a demo one week later. If you want changes or the next piece of the idea, you book another week at the same price, as many times as you like, and there's no contract that keeps you going past the point where you have your answer.

  • A working prototype with a hosted demo link you can share
  • The code in your own GitHub account
  • A recorded walkthrough of how it works
  • A handoff note for whoever builds the production version

Put that next to the cost of building the wrong thing. If one week tells you the idea needs changes before you commit a full build budget to it, or that your team won't use the tool the way you expected, that's the cheapest lesson you'll get in the whole project.

I bill after the demo. If you're not happy with the prototype, tell me and you don't pay for the week. If you're happy and want more built, we book another week at $1,000.

The questions I'd ask if I were you.

Why not just vibe-code it myself?

You can, and for some ideas you should, because the AI app builders are good and I use AI tools every day myself. Where most people get stuck is the last stretch, which is logins, real data, a backend that holds together and a design that doesn't look like every other AI template. My week goes to those parts plus the judgment calls about what to cut, so your time goes to testing the idea instead of fighting the tool.

What happens after the week?

You own everything, and then the choice is yours. You can stop with your answer, book another week to revise or extend it, hand the prototype and handoff note to your own developers, or have me introduce you to developers I trust to build the production version. If you want a long-term technical partner who builds and looks after the software your business runs on, that's what the Founding Tech Partner arrangement is for.

Can anything real get built in one week?

Yes, because the first job is scoping and not coding. We cut the idea down to the one flow that proves it, and the week ends with that flow working rather than a bigger build that's half done. If your idea needs more, you'll see exactly what's left and can decide whether a second week is worth $1,000.

What if the week doesn't go the way we planned?

I bill after the demo, so if you're not happy with what you see, tell me and you don't pay for the week. If you want to keep going instead, the next week is another $1,000, and we can scope it together at the demo.

Why won't you deploy it to production?

Because production is a different job, with security, hosting, monitoring and support that someone needs to own for years, and I'd rather do one week of prototyping well than sell you a launch I won't be there to maintain. You still get a hosted demo link to share, and the code and the handoff note are written so the developers who own the production version can pick it up quickly.

Can I prototype an idea in finance or healthcare?

Yes, because a prototype isn't a production system, so ideas in finance, healthcare and other regulated fields are fine for a sprint, and the handoff note gives whoever builds the real version a clear starting point.

I'm not technical. Is that a problem?

Not at all, and you don't need to be. You bring the idea and what you know about your customers or your team, I handle the technical side, and the walkthrough and handoff note explain it in plain English.

Do I own the code?

Yes. It lives in your own GitHub account, and every line of it belongs to you, whether you build the next version with me, your own team or someone else entirely.

What if my idea is too big for one week?

Most good ideas are, which is why kickoff is about finding the smallest version that answers your biggest question. If the full idea needs three or four weeks, we'll build it one working piece at a time, and you can stop after any of them.

Find out if it works before you find out what it costs.

Book one week, and at the end of it you'll have a working version of your idea at a link you can share, the code in your own GitHub and a clear sense of whether it deserves the bigger investment.
