What you learn spending other people's money
Reyter's founder, Gabriel Facenda, is a physics engineer who ended up in an unusual seat: running paid acquisition for Silicon Valley startups. For three years the job was to take venture money and turn it into customers, on a scoreboard that updated every single day.
That environment teaches you something specific. Not "creative best practices" — arithmetic. What a customer is actually worth. Which keyword is quietly draining the budget. Why a campaign that looks great in the dashboard is losing money in the bank account.
Three things moved the number, every time: measuring the right event, fixing the page before the ad, and cutting the loser in week two instead of week ten. Everything else was noise.
