Overview

Project overview

The founders had validated demand for a compliance tracking tool for small businesses through interviews and a waiting list.

They needed a working, billable product quickly, built properly enough to grow.

The challenge

Big idea, fixed budget

Three constraints shaped the project:

01

A long wish list

The initial feature list would have taken a year to build.

02

Fixed funding

The budget had to cover launch and early improvements.

03

Billing from day one

The product needed subscriptions and invoices at launch.

Goals

What success looked like

  • Launch a paid productwithin three months.
  • Keep scope to one core journeyplus billing and admin.
  • Convert waiting-list usersto paying customers.
