My Bottom Line: Suranga Chandratillake, Blinkx

Technology entrepreneur Suranga Chandratillake is the founder of video and audio search engine Blinkx.

He says there is a huge difference between the nature of the innovation that takes place in Silicon Valley and the rest of the world.

While cities like London and Cambridge may also have plenty of clever people, and access to start-up capital, Suranga says the key difference is mentality.

Suranga says that in Silicon Valley there is a default position to take risks, to try something new and not to take the standard route through the corporate world.

Importantly, there is no negative connotation attached to failure in Silicon Valley, either - and this in turn will not effect your future job prospects of investment opportunities as it might in other parts of the world.

Suranga appeared on The Bottom Line which is broadcast on BBC Radio 4 and BBC World Service. Listen again via the download or watch it on the BBC News Channel.
