We accept payments via both Stripe and PayPal, and I have to say, trying to find a baremetrics-esque solution for us has been insanely frustrating. We're still calculating LTV, churn, etc. by hand since surprisingly none of these services actually support both, and by looking at the metrics from only one payment source we're missing out on the bigger picture.

So glad to see someone finally made one for PayPal, but without support for other payment systems, I don't see it being able to compete with what's out there. This would only be useful for a company accepting payments from JUST PayPal, which as others have pointed out is probably a rare case these days.

ChartMogul claims to be working on PayPal support, so hopefully that will come through. In the meantime, I still think there's a huge hole in this market for supporting PayPal + other services.
