San Diego is one of the most quietly advanced innovation markets in the United States. Biotech and life sciences, defense and aerospace, healthcare, SaaS, climate tech — this city produces deep expertise without shouting about it. And that’s exactly why this question is starting to surface here.

But credibility alone no longer guarantees visibility.

As AI-powered search takes over discovery, recommendations, and decision-making, many San Diego companies are realizing something uncomfortable: despite world-class expertise, they’re barely showing up in AI-generated answers. Meanwhile, louder or more aggressively marketed brands dominate ChatGPT, Google AI Overviews, and Perplexity.

That’s not an accident.
