  • My Amazon Side Hustle Brings In $409K A Year — At Age 17…

Description 👇

Bella Lin, 17, is the founder of GuineaLoft, a company that sells products for small pets, including guinea pig cages, bedding, food feeders and water bottles. In 2024, GuineaLoft has brought in an average of $71,000 per month in revenue so far.

She only launched this in 2022, wasn’t happy with the products available for her pet guinea pigs and started building her own.

Given that it’s physical products her profit margin is probably 10-20%, but that’s still $7-14K per month only two years in 🤑

Maybe there’s an opportunity to do something like this for other pets.

Cats and dogs would be tough, but pet birds and lizards are just as popular as guinea pigs and the market is likely much less competitive.
