Editorial Perspective
L Marks is London's leading corporate innovation platform—they design and run accelerator programmes that connect startups with major corporates. In PropTech/ConTech, they operate RElab with Goldacre (PropTech scale-ups) and have run programmes with British Land, Landsec, and other major landlords. The value isn't the cheque (small grants/investments) but the corporate pilot pipeline—L Marks programmes give startups direct access to decision-makers at the UK's largest property companies. Best fit for PropTech founders who need their first enterprise customer or pilot, not their first cheque. The corporate partnerships validate product-market-fit and often lead to commercial contracts worth far more than the investment.

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.
