It started with Squares, to Blocks and now it's Spirals
I see they are hiring a lot of people and not just for Spiral, but they recently posted job requirement for new hardware wallet they are making.
Jack Dorsey is very serious about Bitcoin and I have to say that I like him more now, than before when he was head of Twatter.
I think he even created special fund to help Bitcoin developers get deserved donations/paychecks.
Interesting thing about Spiral:
Spiral Grants
Get paid in bitcoin to work on bitcoin. Our grant process financially supports developers and designers in over a dozen countries and counting.
