Business, innovation and energy minister Paul Wheelhouse said: “If we can capitalise on the ingenuity of our young people, Scotland can, and will, remain a world leader in renewable energy for many years to come, and I look forward to hearing more about the winner at the final of Venturefest.”
Venturefest connects business owners, entrepreneurs, investors and innovators and provides a platform for companies to access the tools, advice and funding they need to take their businesses to the next level.
An “innovation showcase” will see some of Scotland’s most innovative companies present their products and services to an audience of investors and entrepreneurs.
Intellectual property firm Marks & Clerk, which is sponsoring the showcase element, said there was an increasing awareness among Scots firms that disruption can be an opportunity rather than a threat.
Patent attorney Graham McGlashan said: “We’ve seen more and more young Scottish businesses finding the confidence to be quick adopters and exploiting the power of disruptive technologies.”
