Hard to vet when you are not technical
A low quote can hide the real risk: unclear scope, missed handoff, fragile code, or a build that stalls right when it starts to matter.

Hi, I'm Kat.
Engineer, founder, and creator. From the first conversation to your product handover, you work with me.
- Fixed price · No surprise bills
- The code is 100% yours
- 14 days of free help after launch
- Nothing to pay until we agree the plan
The real problem
Your idea is clear. The build path is the confusing part.
Most founders do not need more motivation. They need a calm, honest answer to one question: what is the smallest real app that proves this business can work?
Agency
Too much process for a first version
Strategy calls, project managers, and big discovery phases can be useful later. For version one, ask which parts of that process your product actually needs.
DIY or AI tools
Great for prototypes, risky for launch
AI builders and tutorials can help you explore the idea. They are less forgiving when real users, payments, privacy, mobile behavior, and ownership enter the room.
Build with Kat is the middle path: one senior builder, one fixed scope, one launchable product, and the code handed to you at the end.
How it works
Three steps. No surprises.
- 01
Tell me your idea
Book a free 15-minute call. No pitch deck, no tech jargon. Just tell me what you want to build and who it's for.
- 02
I scope and price it
After scoping, you get a fixed quote and a simple written plan. If it's too big for three weeks, I'll say so — and we'll split it into a launch and a v2.
- 03
I build and ship
Three weeks of focused work. You get a private link to watch it come together, and updates every few days so nothing feels like a mystery. We agree the start date together; App Store review can take additional time.
What you can build
Whatever you'd sell to your audience tomorrow.
A paid community
A members-only chat, weekly live sessions, resources just for them.
For creators tired of giving it all away on Substack and Instagram.
A course or cohort
Lessons, payments, progress tracking — all on your own website.
For coaches, ex-bankers, and teachers running a 4-week programme.
A small SaaS
One painful problem, solved well, billed monthly. You own the product and the recurring revenue.
For ex-operators who keep saying “I wish this existed” and want to ship it.
A tool for everyday life
A focused little app your community will open daily.
Habit tracker, family planner, fitness log, or a tool for your community — your idea.
What you actually get
A real product — not a prototype.
Ready for your first users
A working core journey, tested before handover. Web deployment or iOS submission support is included in the agreed scope; App Store review is separate.
Designed to look the part
A clear interface built around your audience and brand. Review the key screens before development begins.
Built like the apps you actually use
Common frameworks, documented setup, and a codebase another developer can continue working on after handover.
Yours to keep, forever
The code, the design files, the keys to everything — all yours from day one. No subscriptions to me. No vendor holding it hostage.
Your project, clearly scoped
A clear plan.
A quote for your build.
Every app needs a different first version. Tell me who it is for and what it needs to do. I’ll help shape the scope and send a fixed quote before you commit.
Your quote depends on the platform, core workflows, integrations, and design needs. We agree the deliverables, timeline, payment milestones, and any ongoing service costs in writing.

Web app
For tools, client portals, booking products, and memberships people can use in a browser.
iPhone app
For a product that belongs on a phone, with TestFlight testing and App Store submission support.
Web + iPhone
For a product that needs both. We agree what each platform needs before committing to the build.
- A written scope and fixed project quote
- Source code and accounts handed over
- 14 days of post-launch bug fixes
Why I built this
More ideas deserve to ship — by a founder who's shipped her own.
I'm a founder, developer, and creator. I started out in consulting and investment banking, jumped into tech, then left to build my own companies — and I've spent the years since growing them. Along the way, the same kind of message kept landing in my inbox: a founder, a real audience, a clear idea — and no way to turn it into a real product without spending six figures and six months.
Parents working between school runs. Ex-consultants with a course already written in their head. Creators sitting on a community they could be charging for. None of them needed a co-founder. They needed someone to actually build the thing — properly, on time, on a price they could plan around — and hand them the keys.
Built with: Next.js · Expo · Tailwind · Supabase · Stripe · Vercel.
Why founders trust the process
Know what you are getting.
A written plan, regular progress updates, and a clear handover give you visibility from the first call to launch.
You see the scope before you pay
The first call is not a sales performance. It is a fit check: what can ship, what should wait, and whether a 3-week build is the right route.
You own the working product
The repository, hosting setup, payment account, domain, and App Store account live with you wherever possible, so another developer can help later.
You are not buying a mystery box
You get direct communication with the person building the app, regular screen-level updates, and a handoff that explains what was built.
