You describe it. We ship it

Bring the idea in whatever shape it’s in (a sketch, a voice note, a spreadsheet you’ve outgrown) and take back working software, built by the engineers you actually talk to.

  • No middlemen
  • Fixed price
  • You own the code
What we build

Four things, done well. Not forty done badly.

Full attention, honest judgement and direct communication, from the first line of code to the production handoff. Websites and online stores too, at a fixed price.

01

Custom software

Built to your shape, not theirs.

For the problems off-the-shelf tools can’t solve, designed around how your team actually works.


  • Internal tools that match your real workflow
  • Automation that retires the spreadsheets
  • Integrations with the tools you already use

Software that fits. Not workarounds.

02

Web applications

Fast, modern, accountable.

Production web apps on the stack that ships best. Performance is a feature, not an afterthought.


  • React, Next.js, Astro and TypeScript
  • Auth, roles and row-level security that hold
  • Stripe billing that reconciles

Apps that load fast and convert.

03

Calling & telecom

Your dialer, your carrier.

Click-to-call, outbound dialers, IVR, recording and transcripts, built on the carrier you already pay.


  • Twilio, Telnyx, SignalWire, Asterisk, SIP
  • WebRTC agents in the browser
  • Compliance limits enforced in code

Calls that connect, logs you can audit.

04

Mobile apps

Native where it matters.

Swift and Kotlin when the platform should feel like itself, Expo when one codebase is the better trade.


  • iOS and Android, incl. store submission
  • Push, offline cache, signed builds
  • Tested on real devices

An app that is actually on the store.

What we don’t build

Some doors stay closed, on purpose.

We don’t take on work for, or in support of, businesses in these areas. Better said here than halfway through a call.

  • Tobacco, vaping & shisha
  • Gambling, betting & lotteries
  • Adult content & escort services
  • Cannabis & recreational drugs
  • Pork & pork products
  • Interest-based lending
  • Forex, binary options & crypto speculation
  • MLM & pyramid schemes
  • Paid fortune telling & astrology
  • Defamation, doxxing & harassment
  • Bribery & kickback schemes
  • Weapons & ammunition trafficking
How we work

From wish to working software.

Four steps, no agency theatre. You say what you want, we tell you what it really takes, then we build it.

Late because of us? 10% off per full week, up to 30%. It’s written into the contract, not a slogan.
  1. 01

    Say what you want

    Day 1

    30 minutes. You describe the thing you wish existed; we ask the questions that turn it into a spec, and tell you honestly if we’re not the right fit.

  2. 02

    The honest version

    Day 2–4

    A one-page scope and architecture sketch with a fixed price and a fixed date. You see all of it before you sign anything.

  3. 03

    It gets built

    Week 1 onward

    Working software at the end of every week, not status updates. You steer something real from week one.

  4. 04

    You own it

    Launch week

    Clean deploy, documentation that doesn’t lie, and the keys. Stay for maintenance or walk away, no lock-in.

FAQ

Questions, answered.

How is the price decided?

Published prices are estimates. After a short scoping call we send a fixed price, it can land lower or higher depending on the details. Once signed, it doesn’t move unless you change the scope in writing.

How much does an online store cost?

It depends on the platform. A store on Shopify or WooCommerce costs far less than a fully custom build, we’ll recommend one and price it after we see your catalogue and needs.

What if you deliver late?

10% comes off the fee for every full week we’re late through our own fault, up to 30%. It’s written into the contract.

Do I own the code?

Yes. Once the final payment is made, the full source code, documentation and accounts are yours. Stay for maintenance or walk away, no lock-in.

Can you work with my existing codebase?

Yes. We join projects mid-flight, audit what’s there and improve it without a rewrite unless one is truly needed.

Do you work with agencies?

Yes, white-label. Partner pricing is available.

What don’t you build?

Desktop applications, and anything on the “What we don’t build” list above. If you’re unsure whether your project fits, just ask.
