Hello everyone,

welcome again to this new article about how I built and sold a micro-saas project in 45 days (I’m not joking).

First of all, who am I?

In my full-time job, I’m an Analyst for a Gambling Company right now. I love numbers, and everything related to this field.

I have a bachelor’s degree in Economics and Management, and another one in International Finance.

I love startups, I love the No-code movement, and everything around the tech world.

So how did I build and sell a SAAS in 45 days? Is that possible? Absolutely yes.

It all started with…

It all started 2 years ago on Twitter.

A new challenge was launched: The Build & Sell Challenge (https://twitter.com/BuildSell30).

Few lines about this challenge:

  • You needed to build and sell something in 30 days
  • You needed to validate your idea in 1–2 weeks
  • The challenge was open to everyone
  • A sequence of activities suggested by the organization

It was an interesting challenge (first edition). So we decided to join it and challenge ourselves.
