Influencer Marketing Measurement: Why $50K Returned $500 (and What She Built After)

Liv Soibelman, head of e-commerce at Blueprint by Bryan Johnson, shares hard-won lessons on influencer marketing measurement after scaling programs from scrappy spreadsheets to 700 creators. She opens with a brutal example: a brand she worked at spent $50,000 on a single YouTube video with a makeup creator and tracked only $500 in return via UTM links. That kind of wasted spend is exactly what pushed her to build tighter systems.

At her current company, where there are no outside investors and cash flow directly controls inventory, she treats return on ad spend as non-negotiable. Her first move was integrating Triple Whale, which connects with Superfiliate and pulls in UTM data to show incremental revenue lift by creator. Beyond revenue, she tracks only one other variable: the cost of gifted product, making sure freebies never outpace returns.

Watch to see how she structures a lean, profitable creator program without a finance team or a big budget.
