Speed isn't the moat. Speed compounded over 12 months is. Most teams ship fast for 3 weeks and call it culture.

Remote didn't kill culture. Bad managers using slack as a surveillance tool did. Tools amplify whatever was already there.

Love the pricing page. The 'free until you make $1k' line is the best onboarding copy I've read this year. Stealing the framing.
