About Isabel
Driving growth through strategic marketing leadership and execution.
Isabel García de Salazar is a Fractional CMO and B2B growth leader specialising in helping organisations scale through clear go-to-market strategies, strong marketing leadership, and commercially aligned execution. With over 25 years of international experience, she has built and led marketing functions across SaaS, technology and professional services organisations — consistently translating business objectives into measurable growth, stronger market positioning and increased revenue performance.
She operates at the intersection of strategy and execution, working closely with CEOs, investors and leadership teams to define how companies go to market, how they scale, and how marketing contributes directly to commercial success. Isabel is particularly effective in environments where organisations are growing, preparing for investment, or entering new markets — bringing clarity, structure and senior leadership without the need for a full-time CMO.
Clarity, structure and senior leadership — without the need for a full-time CMO. Particularly effective in growth-stage and investor-backed environments where speed, clarity and results are critical.
Her experience includes building marketing departments from the ground up, leading global teams, developing partner ecosystems, and aligning marketing with sales to drive demand, conversion and long-term customer value. At Grant & Graham, Isabel supports organisations looking to accelerate growth, strengthen their marketing function, and implement go-to-market strategies that deliver tangible business results.
The Fractional CMO Difference
Three things a fractional CMO delivers that a full-time hire cannot.
Hiring a full-time CMO takes 6–9 months and a six-figure salary. Most growth-stage and investor-backed companies need senior marketing leadership now — not in nine months. Isabel brings 25+ years of international B2B leadership at the speed and scale that growth actually requires.
Speed
Without the Recruitment Cycle
Senior marketing leadership in days, not months — with no recruiting cycle, no onboarding lag, no 90-day learning curve.
Strategy
+ Execution Both Levels of the Stack Operates at both ends — defining go-to-market strategy AND building the team and processes to actually deliver it.
