Thanks for the tips. We’ve implemented some of these measures already and it has helped. We’ve had phone verification from day one for example. we try to balance the opportunity cost when possible.

For example, we lose a lot of potential clients due to them being turned off by the phone verification, though we rationalize that by saying that the support and operational costs are a lot lower this way as the driver can get in touch with the clients should there be any issues.

I think the next steps as you outlined are to build additional flows for fraudulent users and regularly verifying some heuristics on our data. We’ve haven’t gotten there yet due to it not being that pressing, but it’s clear we’ll need to do so as we keep gaining traction.

I’ll definitely keep your contact in hand when we visit this issue further!

I don’t know if you handle customer registration. If you do then a customer registering and then placing a big order ($20 or more) within minutes is a big red flag. We clamped down a big chunk of credit card fraud this way.
