We're a software development agency for founders at every stage. We design, build, launch and grow mobile apps, web apps and AI agents, as one team from idea to revenue, and we stay on after launch.

What we do.

Design and build

A week of discovery, then the product: native or cross-platform mobile apps, typed web apps, and AI agents that do real work inside them. Store listings and the production deploy are ours on launch day.

  • Discovery
  • Product design
  • iOS
  • Android
  • Web
  • AI agents

Launch and grow

Growth is planned in discovery with the product, not bolted on at launch. The agencies we bring in are ones we've launched with before, coordinated by your lead, measured against the numbers your next round needs.

  • Paid acquisition
  • Store optimisation
  • Lifecycle
  • Content
  • Launch PR

After launch

Most founders keep us on a monthly retainer: monitoring, fixes, OS and model updates, new features and a monthly roadmap call. Or take the code and the docs and run it yourself. It was always yours.

Questions founders ask.

We've raised and have milestones to hit before the next round. Can you work to that?
Yes, that's most of our work. Discovery starts from the milestones your next round needs and the plan works back from them. You get a written scope, timeline and budget in the first week, and progress is reported in the same numbers.
We haven't raised yet. Is that a problem?
No. Several of the founders above raised on what we built together. Discovery is fixed-price, and the prototype sprint is designed to put something real in front of users and investors by week three.
We have a CTO, or a team already. How do you fit?
We work inside your repository and your process. Sometimes we're the whole product team, sometimes the design and mobile arm next to your engineers. Discovery includes an audit of what exists; we build on what's sound and tell you plainly what isn't.
Do you take equity?
Our default is cash, so that our advice stays independent of your cap table. For the right early-stage product we'll consider a small equity component alongside a reduced rate. Ask on the first call.
How do the marketing partners work?
Growth is planned in discovery with the product, not bolted on at launch. The partners are agencies we've launched with before: paid acquisition, store optimisation, lifecycle and content. They work under your lead's coordination, you have one plan and one point of contact, and you can contract them directly if you'd rather.
How fast is fast?
Discovery takes a week. A prototype is in front of users by week three. A typical product launches in eight to twelve weeks, and the first growth sprint starts the week after. There's a working build in your hands every Friday.
What does it cost, and how do payments work?
Discovery is a fixed $4,500, credited to the build if you continue. The build is billed per two-week sprint at $16,000; growth and support from $5,000 a month. Discovery is paid to start. Each two-week sprint is invoiced before it begins, and you can stop after any of them.
Who owns the code, the designs and the data?
You do, from the first commit. The repository, the designs, the prompts, the evals and the data are yours. We work in your accounts, so nothing has to be handed over at the end.
Will the AI agent actually work, or is it a demo?
We build each agent around one concrete workflow, wire it to your real data and tools, and write an evaluation suite so we can measure that it does the job. Where the stakes are high, it asks a person before it acts.
How do we start?
Send a brief or book a 30-minute call. The person who'd lead the product reads it, and a written scope and estimate follows within a week.

Have an idea?
Let's take it all the way.
