Key people at Extension Fund.
Extension Fund is a pioneering hybrid venture debt and convertible notes fund based in Madrid and Barcelona, Spain, focused on supporting ambitious early-stage technology startups from pre-seed to Series B. Their mission is to empower bold entrepreneurs building global companies by providing flexible financing solutions that combine debt and equity conversion, tailored to the growth stage of each company. They specialize in sectors such as fintech, insurtech, proptech, cleantech, and e-commerce, leveraging deep operational expertise and a strong network to accelerate portfolio company growth and scale internationally[1][2][3].
Founded by experienced investors and entrepreneurs with backgrounds in investment banking and venture capital, Extension Fund was established to fill a financing gap in Spain’s startup ecosystem by offering venture debt and convertible notes as alternatives to traditional equity rounds. Key partners include Ignacio, a former Goldman Sachs Executive Director with a decade in debt products, and Jordi, a seasoned seed investor with multiple exits. Their approach evolved to blend short-term convertible notes for early-stage companies with venture debt for more mature startups, enabling startups to extend their runway and scale efficiently while preserving equity[2][5].
Extension Fund rides the growing trend of venture debt as a complementary financing tool in the European startup ecosystem, especially in Spain where venture debt options have been limited. The timing is critical as startups seek to extend capital efficiency amid fluctuating equity markets and economic uncertainty. By providing hybrid debt-equity instruments, Extension Fund helps startups optimize their capital structure, reduce dilution, and accelerate growth. Their presence strengthens the Spanish tech ecosystem by enabling more sustainable scaling paths and attracting international attention to local startups[1][3].
Looking ahead, Extension Fund is well-positioned to expand its footprint as venture debt gains traction across Europe. Trends such as increased startup capital needs, cautious equity markets, and the rise of hybrid financing models will likely drive demand for their offerings. Their influence may grow as they deepen sector expertise and broaden their network, potentially becoming a key enabler of Spain’s emergence as a global tech hub. Extension Fund’s hybrid model and founder-centric approach offer a compelling blueprint for venture debt firms aiming to balance growth support with capital efficiency[1][2][3].
