BudgetingKid / Our own MVP

A family budgeting MVP kept free for everyone

We built BudgetingKid to manage pocket money in our own family, explored a commercial launch and chose to keep the product public and free. It is a working example of taking an everyday problem through implementation and a business decision.

A personal starting point

Built for our own family and available for yours

We built BudgetingKid for our own use: a practical way to manage a child's pocket money and discuss spending and saving together. The project grew into a working application that anyone can now use for free.

The product gives parents and children a shared starting point for conversations about allowances, expenses and saving.

From allowance to a shared view

We built the allowance-tracking application in Ruby on Rails and a separate Next.js landing page. Parents can create a child's account, set a weekly allowance, track expenses and share access with family members.

Both the application and the landing page have public source repositories, so the implementation can be explored alongside the live product.

Product learning

A working MVP and a deliberate business decision

Startup school for social projects

WideFix founder Andrei Kaleshka took BudgetingKid through a startup school for social projects and graduated from the program with this project. He found the experience very valuable for thinking through the product and the practical work of bringing it to a wider audience.

Why we chose a noncommercial future

We explored a public commercial launch, then concluded that selling and marketing the product would be too expensive for us. With no marketing budget, we decided to keep BudgetingKid public, free and noncommercial.

The application is available to everyone now. We are keeping it public rather than investing in a broader commercial rollout.

Experience we bring to your MVP

Building our own product meant making decisions about scope, implementation, operating costs and distribution together. That experience helps us discuss what your first version needs and how the work fits your budget. Our ongoing Rails maintenance work also informs how we structure applications for later changes.
