I had no idea where to ask such a question and I tried to read their terms of use / privacy statements / about us page to find info about how this popular cost splitting app makes money to employ people.
They don’t even accept donations. Sounds very sketchy, but apparently they don’t really sell data or even offer this app to businesses. Does anyone know how they make profit?
This is from the Play Store listing of the app
Now I really feel stupid, didn’t check Play Store… thanks a bunch!
I’m curious what kind of data they are selling.
Like Joe always default on his payments? Or Nancy occasionally let Lucy pay the bill. 
Write them and ask
What kind of things people buy would be my guess. Then advertisers can add that to whatever profile they have on you so they can give you ads of products that fit that profile.
I’m never surprised by what data people sell.
I’m always surprised there’s someone buying.
You have made an assumption that they are making a profit. They could be in Startup phase where they are getting their product to market before finalising the monetization method in place.
The guess out of my ass is that they either plan to provide an information pipeline to financial institutions for customer modelling or be bought out by the current Dutch player called Tikkie.

Heh. Dutch 4channers on /int/ were mercilessly mocked as skinflints for this app.
This could also be it, but startup phase for 10 years? I mean that would be believable if it wasn’t for the size of the team.
When you pay people back through the app they take a small commission of the settlement. Other than that it’s probably also not a very expensive app to run due to its simple nature.
I started thinking about how much they’d actually make with this monetization scheme, but they employ 6 software developers and have a team of 4 in the upper management. The company has been running for 10 years with this single product.
Likely data harvesting and selling to advertisers.
Seems to be so according to another reply, thanks for the answer!
