Editorial Perspective
Mosaic Ventures is a London-based Seed/Series A fund ($1–10M cheques) co-founded by ex-Yahoo\! CSO Toby Coppel and ex-Accel partner Simon Levene. They back European founders reimagining the world with AI. PropTech and Real Estate are listed investment areas alongside construction. Their portfolio skews toward platform companies with strong technical moats—AI, ML, cybersecurity. Best fit for PropTech/ConTech founders where the core innovation is an AI or data platform that happens to serve real estate, rather than a point solution. They want companies that can become category-defining European tech platforms. Small portfolio (74 companies, 5 unicorns) means high conviction and deep partner engagement.

Investment Team.
Tomas M. Krogh
Fractional Chief Commercial Officer
I specialize in taking founder-led commercial engines apart until only the parts that work are left standing. Before advising, I operated-scaling a business from zero to the FT1000 list three years running and facilitating 10 billion DKK in property transactions. I don't write polite advisory decks; I give you the exact commercial reality check you need before an investment committee does it for you.
