We just got back from the 2026 Meta Performance Marketing Summit, and the biggest takeaway wasn't a single feature or tool. It was the realization that the brands growing the fastest right now are operating in two completely different worlds at the same time.

Luke Austin breaks down everything we saw, heard, and learned at this year's summit. From Meta's push to make conversion lift studies the backbone of a broader measurement discipline, to the explosive growth of TikTok shops and the creator-led strategies that are reshaping how brands think about growth entirely.

In this episode:

• What Meta revealed about their measurement roadmap at the summit

• How the best brands are building a layered measurement practice with MMM, geo-holdouts, and always-on conversion lift studies

• Why TikTok shops has already leapfrogged Walmart.com as a sales channel

• Meta's upcoming Instagram competitor to TikTok shops

• The shift from media spend-first to creator investment-first growth

• Why the brands crushing it right now are mastering both measurement discipline and creator chaos
