3esi Gives Back in Spam Cup Charity Challenge For the fourth consecutive year, 3esi has been proud to take part in the YYC Tech Gives initiative, in support of the Calgary Food Bank. YYC Tech Gives consists of Calgary’s leading technology companies coming together to raise money for local charities. This year’s fundraising efforts saw the participation of 3esi team members in a competition against other local tech companies to stuff hampers with food donations. The team put up a great fight and had a lot of fun supporting this year’s charity event.
