Top 10 Startups: London’s most valuable mobile app companies

We’ve used Tech Nation’s Data Commons service to narrow down the most successful startups in London, and this week it’s the turn of mobile app-focused companies.

As a business model, apps are lucrative and popular, but highly competitive.

An app can be a hit one day and forgotten the next – so its up to creators and designers to keep the UX fresh and the service invaluable.

They cover the widest possible range of sectors – whether that’s banking, entertainment, shopping, or much more.

And a number of London’s very own have succeeded in becoming renowned and trusted the world over.

Let’s look at the top 10 most successful startups using apps this week:
