Extension Fund

Extension Fund operates a hybrid model: a Seed Pocket for early convertible-note deals and a separate venture-debt line for later-stage, venture-backed companies. The convertible note is designed to convert into equity at a future priced round; the venture-debt instrument offers term loans with more flexible covenants than traditional bank debt.

The firm is led by Ignacio and Jordi, according to its website. Ignacio’s background includes a decade at Goldman Sachs in debt products and founding Lapinta Ventures in 2017. Jordi has a six-year seed-stage investing record with more than 35 investments and six exits.

Extension Fund deploys from pre-seed through Series B. The Seed Pocket and convertible notes serve pre-seed and seed-stage companies; venture debt is reserved for more mature, venture-backed startups that have typically reached institutional equity rounds.

The firm’s stated sector priorities are fintech, insurtech, proptech, cleantech and e-commerce, though the current portfolio also includes positions in SaaS, gaming, cybersecurity and edtech. There is no explicit avoidance language, but the concentration is overwhelmingly digital and asset-light.

Extension Fund states it invests in ambitious founders across Spain. While portfolio companies such as Ukio and Service Club operate in additional European markets, the sourcing, underwriting and majority of portfolio-company headquarters remain in Spain.

Ignacio founded Lapinta Ventures, a London-based investment platform specializing in fintech and insurtech, in 2017. Extension Fund represents a continuation and broadening of that activity into a dedicated hybrid-debt fund structure, with Ignacio bringing the same sector expertise to the current vehicle.

The firm characterizes itself as 'more than a financial partner,' citing strategic support, network activation for business development, and financing-structuring help. It does not publicly disclose whether this translates into formal board representation, though the high-touch posture suggests close operational engagement with founders.
