Ruben Lozano

11 years. 7 countries. One obsession: making B2B marketing actually work.

I’m a Fractional Growth Marketing Specialist working with B2B SaaS startups, SMBs, and enterprise companies across fintech, healthtech, edtech, e-commerce, real estate, and HR tech. My work spans paid advertising, product and web analytics, experimentation, CRO, outbound, GTM engineering, and AI-powered marketing — the full stack, end-to-end.

Most marketers consult. I build. I get hands-on with campaigns, tracking setups, experiments, and growth systems — and I don’t leave until the work is done and the numbers move.

I also mentor at GrowthMentor, ADPList, and BridgeForBillions, which means I stay sharp on what’s working across the industry — not just in one company.

If you need a senior growth partner who delivers, not just advises — let’s talk.
