Real Growth Matters is a growth marketing agency San Diego-headquartered brands hire when their addressable market is the entire English-speaking world. We operate national and global programs for San Diego-headquartered biotech, consumer-DTC, and venture-backed HQs. We are not the local-market specialist who wins San Diego consumer media — we are the agency for the founder whose customers live in 200 cities and whose team needs senior strategic media partnership. By **David Schaefer** · [LinkedIn](https://www.linkedin.com/in/daschaefer/) · Updated May 2026 ## What this page is, and what it is not This page targets the search "growth marketing agency San Diego" for brands headquartered in San Diego that are scaling nationally and globally. It is not for brands that want a local San Diego-market specialist. The agency that wins San Diego consumer media is a different agency than the one that helps a San Diego-headquartered brand scale to every major US metro. Most "growth marketing agency San Diego" search results target the wrong buyer. They describe how to win San Diego consumer attention. Useful work, but not our work. Our buyer is the founder or CMO whose product ships nationwide and whose paid-media plan runs across every major metro. The constraint is national scale, not San Diego mindshare. ## Who hires RGM in San Diego Three buyer profiles. The pattern is consistent across San Diego-headquartered biotech, consumer-DTC, and venture-backed HQs. 1. **Venture-backed brands in Series B through Series D.** Product-market fit is real. The cohort retention curves are real. The growth constraint has moved from "do we have a product" to "can we systematize acquisition." 2. **PE-portfolio companies in growth mode.** Holding period 3 to 7 years. Quarterly board reviews on CAC payback and contribution margin. The investment thesis depends on scaling the customer-acquisition engine. 3. **Founder-led brands past repeatable growth.** The founder has built the first 1,000 customers personally. They need a senior marketing partner who can institutionalize what worked without breaking it. ## How San Diego headquarters matters to the engagement Geography matters because senior strategic work happens in rooms. We meet on-site quarterly with San Diego clients. The media strategy itself is national — but the working relationship is in person where it matters. What San Diego HQ does NOT change is the media strategy. The paid-media plan looks the same whether the client is headquartered in San Diego, NYC, Austin, or Miami. National Google Search. National Meta Advantage+. The Trade Desk for programmatic. CTV through the major platforms. San Diego HQ is a relationship convenience, not a strategic input.
