Episode notes
Built Solution From Personal Pain
- Angus built the first version to solve his own need for multi-year transaction data in Excel and had to extract data from PDF bank statements.
- He generalized the code, launched an MVP with a friend, bought Google ads, and immediately got uploads which validated demand.
Launch Fast With A Tiny MVP
- Make an MVP as quickly as possible and get it in front of real users instead of over-validating before launch.
- If you can build an MVP in one or two weeks, just launch and learn from actual usage.
From Console App To Live Product
- Angus prototyped locally in Kotlin as a console app then generalized it to support other banks and added a Next.js UI built by a friend.
- He hosted the frontend on Netlify and the backend on an AWS EC2 instance to deploy the product.
