I didn’t expect this to work, but I made $800 just by referring 2 people

Side hustles

Just wanted to share something that worked for me in case it helps someone else.

I’ve been using LeakSense (they sell water leak detection devices for properties), and I noticed they have a referral program. I didn’t think much of it at first, but I shared it with two people I know who manage properties.

One of them ended up buying 50 devices, the other bought 30. The referral commission is $10 per device, so that came out to $800 total for me.

There’s no upfront cost, no recruiting or MLM stuff - it’s a straight referral link. If someone buys through your link, you get paid per device.

The only catch: LeakSense operates in California, so the people you refer need to be based there (property managers, landlords, HOAs, etc.).

If you want to check it out, the referral program is here:

I’m not saying this is some magic passive income or that everyone will make money, but if you already know people in California real estate or property management, it might be worth a look.

Happy to answer questions or explain how it worked for me.
