What I'm looking for

I’m looking to lead GTM and growth marketing that’s tightly linked to RevOps—using ABM/PLG, CRO, and experimentation to build measurable pipeline engines, align sales and marketing, and accelerate growth in enterprise and mid-market B2B SaaS.

I’m a Strategic Growth Marketing Leader with 10+ years scaling B2B SaaS revenue engines through full-funnel growth marketing and data-backed experimentation. I build GTM strategy into measurable pipeline growth across enterprise and mid-market segments, with clear focus on outcomes like lowering CAC, improving LTV, and compressing sales cycles.

I lead and align demand generation, capture, and RevOps so marketing and sales move as one system. My approach blends ABM, PLG & SLG motions, rigorous funnel velocity optimization, and CAC/LTV/ROI optimization to drive sustainable growth.

In my work as a Founder & Principal Consultant, I source and rebuild revenue engines—often combining research-led positioning, sales-process redesign, demand generation, and ABM. I also built AI-enabled business systems (including HubSpot-related extensions and automated content operations) to monitor funnels, competitors, and key-person activity, then surface recommended actions.

I’ve also held roles including Fractional VP Marketing & Growth Advisor, Demand Generation & Revenue Operations Lead, and Director/Head of Marketing. Across these experiences, I’ve improved demo rates, reduced unqualified leads, increased inbound meeting rates, and delivered repeatable engines using paid/organic channels, CRO, and lifecycle marketing.
