The speed at which Polar is executing on the financial infrastructure primitives the new world needs is very impressive.

I've joined Polar as an advisor!
I think it benefits everyone for devs to have more options to get paid to work on their passions, to support upstreams, and for users to have more confidence/transparency in the software they're supporting/purchasing.

I switched to Polar a few weeks back. Best decision ever.
One flat rate covers payment processing, global tax compliance, and reliable support. No monthly fees, no setup costs.
