Built by someone who's done this before.

Mike has spent more than 10 years in Amazon advertising. He created PPC Entourage, the Amazon advertising software company acquired by Carbon6 in 2021, and managed more than $50 million in ad spend along the way.

When ChatGPT Ads launched, he saw the same pattern he'd watched on Amazon a decade earlier: a new ad channel, plenty of excitement, and no clear way to tell which spend actually turns into customers. He built Big Hint to answer that question for agencies and brands: which ads bring leads and booked calls, what each one costs, and what to change next.
