Frequently asked questions

What investment stage does Addendum Capital target?

Addendum Capital focuses on early-stage investments, providing initial rounds of institutional capital to companies. The firm's public description and regulatory filings consistently identify early-stage equity as its core mandate. This includes seed and Series A equivalent rounds within the Spanish and broader Southern European markets.

Is Addendum Capital structured as a family office or a traditional private equity firm?

Addendum Capital operates as a traditional private equity asset manager, not a single-family or multi-family office. Its corporate registration in Madrid and self-description as a private equity firm confirm a third-party capital management structure. No wealth-origin narrative — such as a founding family's operating business — has been tied to the firm in public disclosures.

Does Addendum Capital participate in fund commitments or only direct deals?

Addendum Capital's disclosed strategy centers on direct equity investments into early-stage companies. The firm has not indicated a fund-of-funds allocation or a practice of committing capital to external private equity or venture funds. This direct-deal posture is consistent with a lean, early-stage investment firm without a multi-strategy platform.

Where does Addendum Capital source its deal flow?

Addendum Capital sources opportunities primarily within Spain and Southern Europe, leveraging its Madrid headquarters. Specific origination channels — such as accelerator partnerships, university spin-out relationships, or proprietary advisor networks — have not been detailed in public record. The firm's local presence suggests a reliance on on-the-ground networks rather than pan-European auction processes.

What sectors does Addendum Capital explicitly avoid?

Addendum Capital has not published an explicit restricted-sector list or negative screening criteria. Given its early-stage equity focus, the firm is unlikely to meaningfully participate in infrastructure, real estate debt, or late-stage buyouts. Without a public investment policy statement, any sector exclusion should be considered unconfirmed.
