Hi, I'm Kat.

- The code is 100% yours
- 14 days of free help after launch
- Nothing to pay until we agree the plan
The problem
You've had the idea for months.
Sketches on a napkin. A spreadsheet doing the job an app should be doing. A folder of DMs asking when it'll launch. You don't need a co-founder. You just need someone to actually build the thing.
Hire a freelancer who ghosts
A great first call. A solid quote. Then silence at 60% done — and your deposit gone with them.
Get quoted $30K by an agency
Just to build the first version of an idea you haven't even tested yet. The kind that might change after your first hundred users anyway.
Code it yourself between school runs
Three tutorials, four crashes, still no app. Your evenings are worth more than that.
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
Within 48 hours, you get a fixed price and a simple one-page 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. Day 21, you're live.
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 small tool for mums
A focused little app your community will open daily.
Cycle tracker, sleep log, mum planner, postpartum companion — your idea.
What you actually get
A real product — not a prototype.
Live on launch day
Real, finished, and ready for paying customers from day one — on your own website, or live on the App Store.
Designed to look the part
Clean, modern, beautifully designed. Looks like you spent ten times what you actually did.
Built like the apps you actually use
Made with the same kind of technology behind Instagram, Notion, and the apps you open every day. Solid, fast, and ready to grow with you.
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.

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 brilliant woman, a real audience, a clear idea — and no way to turn it into a real product without spending six figures and six months.
Mums 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.
A few things I've shipped
What people say
Don't just take my word for it.
“I sat on this idea for two years, scared of the $30K quotes. Kat shipped it in three weeks and I made the build cost back in a month.”
Sara M.
Founder, paid newsletter (12K subs)
“She just gets it. No 47-page Notion doc, no kickoff theatre. We talked, she built, I have a real product. I think of her as my CTO.”
Annabel K.
Ex-MBB consultant turned coach
“First developer I've worked with who actually finished — and explained the code so clearly I could hire someone else later if I needed to.”
Priya R.
Wellness creator, mum of two (45K IG)
