About Ruben
Who I am
Fractional Growth Marketing Specialist with 11 years of experience across B2B SaaS, SMB, and enterprise. I've worked in 7 countries across fintech, healthtech, edtech, real estate, HR tech, and more.
What I do
- Paid advertising (Google, Meta, LinkedIn, Bing)
- Web & product analytics (GA4, Mixpanel, Amplitude)
- Experimentation & A/B testing
- Conversion rate optimisation (CRO)
- Email marketing & outbound
- GTM engineering & tag management
- Data-driven marketing & reporting
- AI-powered marketing
How I work
I'm an executor. I know strategy and tactics, but what I enjoy most is the hands-on work — building campaigns, setting up tracking, running experiments, and shipping results. I bridge the gap between strategy and execution so nothing gets lost in translation.
Beyond client work
I mentor at GrowthMentor, ADPList, and BridgeForBillions. I share real marketing experiments and frameworks on rubenlozano.me.
