Launch48 event sees the start of new sites.
The Launch48 event, held at Birmingham Science Park Aston (BSPA), brought together web development, design, marketing and management professionals from the region.
Between them they created two new web businesses - Twitballot, an application that allows users to quickly set up a voting system on Twitter and HereToNetwork, a site which helps people network better when they go to events.
Launch48 was hosted and sponsored by Entrepreneurs for the Future (E4F) at BSPA, a programme to help the next generation of technology entrepreneurs in the West Midlands deliver commercial success.
Simon Jenner, manager of E4F, said: "Achieving what seems like an impossible challenge - creating not one but two fully formed applications within just 48 hours - demonstrates the wealth of digital talent we have here in the West Midlands.
"High tech, high growth businesses in IT, digital media, clean/green tech, medical technology and bio technology are essential for the region's future prosperity, so initiatives like Launch48 which encourage experts in these areas to meet and collaborate are fantastic.
Experienced mentors from established companies such as Paypal, Dennis Publishing, Majestic 12 and Talis were on hand to ensure projects were supported with robust business plans.
Mentor Mark Hales, a Birmingham venture capitalist who invests in SMEs, said: "It's hugely exciting to see a new generation of bright young entrepreneurs in the West Midlands working together to create new ideas."
