Every package includes: your app designed for free before you pay anything · NDA signed before we start · you own 100% of the code · weekly progress meetings with a live preview link · 60 days of free bug fixes after delivery, then just $29/hour · pay up front or split into weekly payments.
For founders who want to test an idea — or business owners who need one simple tool — without building a full platform.
- Free custom design before you build
- One core feature, built to actually work — a calculator, booking form, quote generator, quiz, or any single-purpose tool
- Up to 3 custom-designed screens
- No accounts or logins to manage — anyone opens it and uses it instantly
- Works on every device through a link you can share anywhere, put in your bio, or run ads to
- You own 100% of the code — no lock-in
Best for: testing demand before a bigger build, or adding a lead-generating tool to an existing business.
For founders ready for an app people sign into, come back to, and pay for. Everything in Kickstart, plus:
- User accounts & secure login — your app remembers every user and their data
- Your core feature backed by a real database
- Unlimited API integrations — payments, text messages, calendars, or any tool you already use
- Take payments online — start earning from day one
- Runs on every device — iPhone, Android, and web
- Published to the App Store & Google Play for you
- Custom store screenshots + App Store Optimization (ASO) so people actually download it
- Onboarding flow designed to turn downloads into signups
Best for: your first real product — the app you've been telling people about.
For founders whose idea is the AI — smart recommendations, chat, generation, matching. We build the intelligence and the way it makes money. Everything in Launch, plus:
- Custom AI features built right into your app — chat, recommendations, image generation, smart search & matching, or whatever fits your idea
- AI accuracy checks — a second AI verifies results before your users ever see them
- Subscription billing with free & premium tiers — designed so free users get hooked and upgrade
- Conversion-optimized onboarding and paywall, modeled on what works in our own profitable apps
- A clear running-cost breakdown — know exactly what each user costs you before you launch
- More screens for a richer app
Best for: AI-powered products with recurring revenue — the apps we get most excited to build.
For founders building the next two-sided marketplace: think Uber, DoorDash, or a job board — apps where different kinds of users interact in real time. Everything in Automate, plus:
- Multiple user types — customers, providers, drivers, businesses — each with their own custom interface
- Your own admin dashboard to see and manage everything happening in your app
- Real-time features — live maps, order tracking, status updates, and in-app messaging between users
- Marketplace & vendor integrations — pull in products, process multi-vendor orders, track fulfillment
- Team accounts & roles — let your users invite their whole company
- Unlimited screens and unlimited API integrations
Best for: two-sided marketplaces and platforms — the apps that build unstoppable network effects.
Timelines cover the build itself. Kickstart is web-only, so it goes live the moment we're done — for Launch and up, App Store & Google Play review adds 1–3 weeks after the build, and we handle that process for you.
Hey, I'm Tristyn 👋
I started TristynTech because I got tired of watching good founders get burned — ghosted by freelancers, quoted $40k by an agency, and left with a half-built app that never shipped.
I've been in your seat. I spent 10 years as a software engineer at Austin startups, building products of my own along the way — including one I sold. I know exactly what it's like to have an idea you believe in and just need someone who can actually build it — fast, and without the runaround.
In that time I've shipped products that raised over $20M in funding, watched MVPs we built land deals with Fortune 500 companies, and helped founders go from a napkin sketch to a funded startup.
So when you work with us, you're not handing your idea to a stranger you'll never hear from again. You get a team that has actually shipped — real products, real users, real funding raised — that moves fast, tells you the truth, and treats your app like it's our own until it's live and working.
We've built our own products. We've had our own exit. Now I'd love to help you build yours.
A quick look at how we work — straight from the founder.
Questions, answered
What's the free design, and how does it work?
First we hop on a quick planning call so we understand exactly what you're building. Then, usually the next day, we design your app idea for free — real screens, your concept, made by us. You'll have the designs in hand to keep. If you love them, we build it. If not, you owe nothing. It's the easiest way to see exactly what you'd be getting, completely risk-free.
What's included for $2,997?
The $2,997 Kickstart is a single-purpose tool: one core feature — a calculator, booking form, quote generator, quiz, that kind of thing — across up to 3 custom-designed screens. No accounts or logins to manage; it lives on the web at a link you can share anywhere or run ads to, and it works on every device. You own 100% of the code. If you need logins, payments, or the app stores, that's Launch at $5,997 — we'll figure out the right fit on your free call.
Is 2 weeks actually realistic?
Yes — for a focused first version with a clear plan. We nail down what we're building on the call, then move fast as a dedicated team. We've done it repeatedly — Kenton at ClearSky was demoing his app to enterprise clients within 2 weeks of starting. If your app is bigger, we'll tell you upfront and give you an honest timeline.
What if my app needs more than 5 screens?
No problem — we'll figure that out on the call. For bigger apps we'll point you to the right option, or we can build your core app first and add to it from there. We'd rather plan it honestly than over-promise.
What kinds of apps do you build?
Just about anything — websites and web apps, mobile apps for iPhone and Android, AI tools, booking and scheduling apps, customer portals, internal tools that replace spreadsheets and manual work, and more. If it lives on a screen, we can build it. We've made everything from a family caregiver app to a property tax advisor to software that landed a Fortune 500 deal in its first month.
Who actually builds my app?
Senior engineers on our team, based across the US and the Philippines. Tristyn, the founder, spent 10+ years building at Austin startups — including products that raised over $20M and one successful exit. You work directly with the team, not a junior contractor you've never met.
Do I own everything when it's done?
Yes, completely. When we hand off your app, all of it is yours — no lock-in and no ongoing dependency on us unless you want it.
Am I stuck with you forever?
No. We build custom apps with real, raw code — JavaScript, React, Firebase, and other standard tools — so any other engineering team can pick up right where we left off. You're never locked in.
I'm not technical — is that a problem?
Not at all. You don't need to know anything technical. You bring the idea and the vision for your business; we handle all the building, and we explain everything in plain English along the way.
What happens after it's built?
It's yours to run. If you'd like us to keep improving it, add features, or stay on as your ongoing development team, plenty of clients do — but it's entirely up to you. There's no required support contract.
What about ongoing maintenance?
We fix any bugs free for 60 days after your app is delivered. After that, any new work or ongoing maintenance is just $29/hour — no retainer, no minimums. You only pay for what you actually need.
Are there any other costs?
The flat rate covers design and building your app. The only extras are things like hosting and a web address, paid directly to those providers (usually $10–50/month). We'll tell you exactly what to set up and walk you through it.
How does payment work?
It's paid up front to get started. If you'd rather spread it out, we can split it into weekly payments instead — whatever works better for you. Either way, nothing is due until after your free call, once you've decided to move forward.
What if I'm not happy with it?
We keep refining until it's right. You'll see the designs before we write any code, and you'll have a live preview link throughout so you can give feedback as we go. Our goal is an app you're genuinely proud of — if something's off, we fix it.
I just have a rough idea — is that enough to start?
Absolutely. That's exactly what the free call is for. Come with whatever you have — a sketch, a few sentences, or an app you want to do better than — and we'll help you turn it into a clear build package. No pitch deck required.
