How a 19-year-old intern built the growth engine behind this $2B AI company | Hector Serrano

Growing a B2B SaaS product requires a foundation of organic product-market fit, which paid channels then amplify. Performance-based user-generated content (UGC) serves as a primary growth lever, where creators receive a percentage of ad spend or GMV rather than flat fees. This model incentivizes high-quality, authentic content and allows for rapid experimentation without the restrictive guidelines of traditional advertising. Hiring young, platform-native talent who prioritize consistency and community engagement provides a significant competitive advantage over traditional resume-based recruiting. Complementing this, founder-led content acts as a long-term brand-building strategy, humanizing the company and lowering customer acquisition costs by establishing trust. Ultimately, maintaining a human-centric approach to content production—avoiding AI-generated output—remains essential for cutting through digital noise and building sustainable, high-performing growth engines.
