Monte Carlo Capital is a Monaco-based venture capital firm that invests in early-stage deeptech, AI, and space technology startups, pairing fund capital with co-investment vehicles to back founders from seed through growth.
Monte Carlo Capital invests in early-stage companies across deep tech, AI, space technology, fintech, commerce, and software, with a particular focus on frontier science being turned into industry-defining businesses.
The firm invests primarily in the United States and Europe, drawing on a global network that also extends into Asia.
The firm typically invests at the pre-seed through Series A stages, with fund check sizes of $350,000 to $500,000 and companion co-investment vehicles (SPVs) that can write checks of $500,000 to $1.5 million, with total exposure to a single company reaching as much as $7 million across multiple rounds.
Monte Carlo Capital positions itself as a value-added co-investor, working alongside firms such as a16z, Atomico, General Catalyst, Insight Partners, Khosla Ventures, and Sequoia.
Monte Carlo Capital has secured a $15 million first close for its second fund, Monte Carlo Capital Fund II, against a $30 million target.
The firm's debut fund, Monte Carlo Capital Fund I, closed at approximately $13 million in 2025, and the majority of its limited partners have recommitted to Fund II.
Fund II had already made five investments at the time of its first close.
