As in the description:

you should have context so you can join with little onboarding
if you have incredible credentials (incredible = raised more than 5mm as a founder, got a product to 500k ARR, main person responsible for an amazing product at a bigger company) apply and let's have a chat!

ps: we're backed by spark capital, felicis, and y combinator ($30m seed — biggest out of YC round) but we still work like a seed startup. you'll be one of the first people showing the world what Sauna can do.
