The Startups team set about finding what we considered to be the 100 best business start-ups - aka Startups 100. Nothing more, nothing less - and our methodology is unashamedly unscientific.

That certainly didn't mean any old business could make our list, though. Far from it!

The search began in earnest six months ago with the only solid criteria being that we'd define 'start-up' as trading post-2005 (we had to draw the line somewhere).

Other than that, anything went. Well, we say anything. What we meant was any new company that, first of all, excited us. Then we wanted to see:

  • Innovation, in concept or delivery
  • Ability to disrupt existing market places
  • Demonstratable growth potential.
  • Strong management, bright thinkers
  • Evidence of existing or future revenues

We put out feelers; we asked other entrepreneurs; we networked until business card consumption became unethical; we looked at awards schemes - starting with our own, of course - we searched areas such as social enterprise and disabled entrepreneurs' organisations and green business initiatives to ensure we'd covered every base represented in today's start-up community.

More than 500 businesses came under our consideration; 200+ made a rather long shortlist; 150 were comprehensively researched; 125 were interviewed.

And, of course, 100 made the cut. We hope you approve.
