The AI-native marketing firm for B2B SaaS
CortexCMO combines senior CMO-level strategy — forged across LinkedIn, Twilio, Realtor.com, and six high-growth SaaS companies — with a proprietary AI execution layer. The result is enterprise-grade marketing at a price point designed for the stage you're actually at.
We kept seeing the same problem — and built the firm to solve it
Time at LinkedIn, Twilio, and Realtor.com showed us what best-in-class B2B marketing looks like at scale — the rigor, the systems, the standard of execution. Then we moved into the startup ecosystem, and the gap was impossible to ignore. Founders with genuinely great products, stalled between $500K and $5M ARR, unable to access the caliber of marketing leadership their growth stage actually demanded.
A full-time CMO costs $200K+. Traditional agencies don't understand SaaS metrics. Freelancers can execute but can't set strategy. There was a real gap — and nobody was filling it with the combination of senior judgment and modern execution it deserved.
CortexCMO was built for that gap. We pair fractional CMO leadership — forged at enterprise companies and early-stage SaaS alike — with a purpose-built AI agent stack, delivering senior-level strategy and high-volume execution at a price point that makes sense for the stage it serves.
"The best marketing isn't the loudest — it's the most precise. Know your buyer better than your competitors do, build content that genuinely serves them, and measure only what connects to revenue. Everything else is theater."
