About Guillermo

I am a digital growth specialist with over 7 years of experience helping CEOs and founding teams scale B2B companies, particularly in SaaS, PropTech, and digital product environments. Throughout my career, both as an in-house lead and in freelance projects, I have driven strategies that have generated over €500,000 ARR in digital acquisition, with CPLs and CPAs below €0.11, and sustained revenue growth exceeding 20% year-on-year.

I design marketing strategies/campaigns with a direct impact on EBITDA, managing cross-functional teams and activating key levers such as SEO, SEM, funnel optimization, and international expansion.
