My daughter was 7yo and wanted to buy video games. Since I don't approve many spendings, I thought I could teach her the value of money with a small weekly allowance.
It worked, I stopped buying things she wanted and she started managing the money. Awesome!
As the founder I am, I created a nocode product do manage the allowance. My friends all wanted as well, so i made it a SaaS.
Here Bankinho is born.
