Hector Serrano runs one of the most innovative and successful paid growth programs in Silicon Valley. As Head of Content at Wispr Flow, a leading AI voice-to-text tool, he built a roster of 50 creators who drive 500 to 600 paid user-generated content (UGC) ads every month. The creators are paid a cut of ad spend, and the best of them earn over $13,000 a month. It’s a playbook the best DTC brands have used for years, now adapted for SaaS. Hector joined Wispr Flow at 19, before the product had PMF, and over the past year, Wispr Flow has grown revenue 30x and raised at a $2 billion valuation.

We discuss:

1. Why paid UGC is one of the biggest untapped growth levers right now

2. The step-by-step playbook for building a successful paid-UGC program

3. Why the best marketers are “allergic to AI”

4. What makes a great modern marketing hire

5. Why YouTube is the most underrated growth lever in SaaS
