Nesta has announced a further 16 awards totalling £1.07m from the £10m Innovation in Giving Fund, which aims to find and back innovative ideas for increasing volunteering and charitable giving.

The organisers of #riotcleanup, which used social networks to arrange clean-ups following last summer’s riots, is among the latest projects to benefit from the Fund, which is managed by Nesta on behalf of the Cabinet Office. 

Also, Guess2Give, the online fundraising sweepstake, has been awarded a £50,000 grant. Anything that can be measured can become a fundraising event using Guess2Give. For example, for the 2012 Virgin London Marathon, runners will ask their friends to guess how long it will take them. Each guess is £3 with up to £2.50 (including Gift Aid) going to charity, and 50p going to the prize fund. The person who guesses closest to their marathon time wins the prize fund

Founder and CEO Mark Chandler said: “We’ve set out to make fundraising more fun and engaging whilst boosting charity coffers. Fundraising is changing and the launch of Guess2Give marks a completely new way to raise money. We’re delighted that Nesta has recognised our innovation and passion”

15 funding awards were announced in February and a further 16 are announced today. The total amount awarded so far (for all 31 projects) is £2.45m.

Over 430 applications for funding were received and 62 were shortlisted to pitch their ideas to a selection panel between December 2011 and March 2012.
