Company name: Thirtyone Fundraising

Description: "Greenpeace can do amazing things to protect the environment, but only if we have huge numbers of people supporting what we do. So the people at Thirtyone are an incredibly important extension of the Greenpeace team, making a direct difference to our campaigns by inspiring thousands of people every year to commit to Greenpeace’s mission. They’re great to work with and great representatives for our work – every successful call is a step closer to saving our planet so the callers really are making a positive impact every day."
