I created the BankDeets form a while ago to collect bank details in any currency. I need the form for the Payspresso project, and I thought others might find it useful as well.
Initially I promoted it on Hacker News and Reddit without much success. I've also shared in on Twitter and found a few potential users that way. After publishing it to NPM, I got around a 1000 downloads, but it's hard to tell if those are real users or just bots.
I'm hoping that by open sourcing the form, I might get an opportunity to speak to people working on similar problems. Maybe even find some customers.
This is the first inbound interest I have gotten through this, which is fun. I hope there will be more in the future.
