Paying for roughly 60 APIs every month. And with Supabase, after $25 it's $599/month?!

Most have garbage terms lifetime deals, 70% commissions, heavy discounts. The math doesn't work unless you're already at scale, and by then you're locked into bad contracts. Wondering how many founders realize their unit economics are actually just paying off vendor debt.

Most agencies I talk to lead with creative.

But the ones actually landing bigger contracts show clients what their market is saying about them first then the creative makes sense. I've been thinking about how MentionFox could be the intelligence layer agencies pitch before the deck.
