Founding members Ryan Brady, Darrin Brooks, Lindsay Doucette, and Marty Posch established Giving Sum in 2008 based on a common desire to do more for the community. Ryan, Darrin, Lindsay and Marty realized their impact would be significantly greater if they pooled their resources and worked together to address community needs.  This equation of the power of many working as one became the formula for Giving Sum.

Giving Sum was also established based on a strong desire to engage people beyond cash contributions. Giving Sum exists to help educate and open doors for emerging leaders to take a larger role in philanthropy and civic engagement in the Greater Indianapolis area. Whether that is getting involved on a board of directors, starting a new community initiative, or simply giving volunteer time, Giving Sum strives to engage and open those doors for you.
