Local density comes first
Gumtree proved it: you do not win by going broad. You win by going narrow. One community, one city, one problem — until the loop works without your intervention. Then you expand.
Profile
Co-founder of Gumtree and Slando. London-based operator who believes the best marketplace investing comes from having built one yourself.

Michael Pennington does not seek the spotlight. He and his co-founder Simon Crookall built Gumtree from scratch in 2000, funded it themselves, handed out flyers at Tube stations and grew it into the UK's largest classifieds site before selling to eBay in 2005. A month later they launched Slando for Russia and Eastern Europe, eventually selling stakes to Naspers. That hands-on experience — the messy early days, the hard decisions about monetisation, the reality of making trust work at scale — is what founders get with Empee Capital, not theory from a distance.
He invests because he believes founders building marketplaces, fintech and digital networks deserve a partner who has lived through the same problems they are facing right now. Not a celebrity. Not a distant advisor. An operator who has been in the trenches and still thinks the most interesting work happens before the story looks clean.
Not just dates. The decisions and constraints that shaped how Michael thinks about marketplace formation.
What matters for founders is not a trophy list. It is the operating conviction that comes from having built, scaled and adapted marketplaces from zero.
Gumtree proved it: you do not win by going broad. You win by going narrow. One community, one city, one problem — until the loop works without your intervention. Then you expand.
Identity, moderation, payments, guarantees, support — these are not afterthoughts. They are the product. If users do not feel safe enough to transact, nothing else matters.
Slando showed that marketplace playbooks do not copy-paste. Every new market has its own trust problem, its own distribution channels, its own regulatory landscape. You rebuild local density from scratch.
