Fractional CMO San Diego — senior marketing leadership for B2B operators here.

Treetop works with B2B mid-market companies in San Diego and across California. If you're a founder or CEO between $3M and $30M ARR considering a fractional CMO, here's the San Diego-specific context and how to think about the engagement.

Short answer

Treetop offers fractional CMO services in San Diego, CA. Engagements run $8K-$25K/month for B2B mid-market companies needing senior marketing leadership without a full-time hire. Remote-first with quarterly in-person on-site for San Diego clients when scope warrants.

Why San Diego's B2B market is its own thing

San Diego's B2B ecosystem is anchored by biotech (Illumina, Qualcomm, etc.), defense (massive Navy presence), and a growing B2B SaaS scene. Marketing rhythm skews toward longer enterprise cycles, conference-heavy outbound, and account-based motions. Lower burn than SF for similar-quality talent.

Practical implications for marketing leadership:

Biotech tools and defense GTM are distinct disciplines. Conference circuit matters.
Talent market for senior fractional operators is mid-large — meaning you have real options without paying SF/NY rates.
Most B2B buyers here want substance over hype. Marketing that survives in San Diego translates well to enterprise sales motion elsewhere.
Pipeline rhythm rewards consistency more than peaks — quarterly cadence beats one-off campaigns.
