Our Approach

Conviction Capital.
Long-Term Partnership.

At Lumino Capital, we believe the most important innovations are rarely obvious. Our thesis-driven approach means we spend years developing deep conviction in a technology domain before we write a single cheque.

We are hands-on investors. From your first board meeting to your follow-on funding, we serve as strategic partners — opening doors to our network of corporate partners, technical advisors, and co-investors across Europe and North America.

Our initial ticket at the seed stage typically ranges between $2M and $5M, with significant reserves for follow-on investment in our highest-conviction companies.

How We Work

Lumino Capital was founded on the belief that exceptional returns are not manufactured through volume � they are earned through patience, precision, and proximity to exceptional founders. We conduct months of diligence before committing, and when we do commit, our partnership extends far beyond the capital itself. Our team engages directly with product development, go-to-market strategy, and executive recruitment to ensure that every portfolio company has the operational backbone to scale sustainably.

"We seek companies where the product itself is the unfair advantage � where the technology is so deeply embedded in the workflow of its users that displacement becomes an act of self-harm for those who rely on it."

� Managing Partner, Lumino Capital

We maintain a deliberately small portfolio � never more than twelve active investments at any given time � because meaningful partnership demands meaningful attention. Each investment receives direct access to our network of European and transatlantic institutional buyers, a hand-curated roster of operating advisors, and regular strategic counsel from our full partnership team. Our LPs include family offices, sovereign-aligned endowments, and a select group of technology executives whose experience and networks amplify every introduction we make on behalf of our founders.
