Package

Your idea is live in 6 weeks. Or we don't charge.

Most software projects are late. Ours aren't. The MVP Sprint is a shaped engagement: we fix the scope before writing a line of code, commit to a date, and ship. Non-negotiably.

What you get

  • A working product in production - not a staging demo
  • Real users able to sign up, pay, and use the core feature on day one
  • Source code and infra fully in your name, fully owned by you
  • 30-day post-launch buffer for bug fixes at no extra cost
  • A clear handoff - runbook, docs, and a walkthrough session
  • Optional Retainer if you want us to keep building after launch

Right for you if ...

  • 01

    You have an idea and need to prove it to users or investors as quickly as possible

  • 02

    You want a fixed price and a firm ship date - no moving scope, no open-ended billing

  • 03

    You are pre-revenue and every week of build time is runway spent

  • 04

    You have been burned by vague estimates before and want a commitment in writing

What we build

Shaping the scope

Week one is discovery. We define the smallest version that proves your idea. Cuts are made by us, agreed by you - before any code is written.

Design + build

We design and build simultaneously. No 4-week design phase followed by a 4-week build. Faster feedback, less waste.

Auth, payments, data

The plumbing that makes a product real: accounts, subscriptions, dashboards, notifications. Scoped tightly but done properly.

Production deployment

Live. Not staging. Users can access it. Monitoring is set up. Errors are surfaced. Backups are running.

Handoff materials

A runbook, a short video walkthrough, env vars documented, deploy process documented. No black boxes.

The stack we reach for

How we work

01

Shape (Week 1)

Discovery call, then we define what gets built. Fixed scope document. Price confirmed. Nothing starts until you've signed off.

02

Build (Weeks 2-5)

Daily Slack updates. Real code in your repo. Weekly demo of working software - not mocks, not slides.

03

Test & polish (Week 5)

End-to-end tests, cross-browser checks, performance baseline, security review. The unsexy work that makes a product trustworthy.

04

Launch (Week 6)

Production deploy, domain, monitoring, a 30-day fix window. You decide when to flip the switch.

Right-fit packages

Fixed prices. No hidden fees.
