About the Startups 100

Now in its 18th year, the Startups 100 is the definitive list of the most promising new UK businesses. There's no fee for entry or for inclusion in our index. The Startups team of new business experts judge all our top 100 entrants in collaboration with specialist industry consultants.

Founders: Alex Chesterman and Simon Kain

Zoopla.co.uk is aiming to become the UK’s most comprehensive source of residential property market information. With the aim of helping buyers, sellers, owners and estate agents gain an advantage in the property market, Alex and Simon set up Zoopla.co.uk following the success of their other venture, LOVEFiLM.com.

The service offers greater transparency to customers, offering free instant value estimates on every UK home and enabling buyers to express interest in any residential property online. The acquisitions of Thinkproperty.com from the Guardian Media Group and the Propertyfinder group in the summer were key turning points for the company last year.
