Bloomberg profiles software mogul Tim Gill, who has mobilized other corporate leaders and gay philanthropists to promote same-sex marriage and antidiscrimination efforts.
Mr. Gill, who founded and later sold publishing-software company Quark, became an activist during a 1992 Colorado referendum campaign to roll back antidiscrimination statutes in the state's biggest cities. He subsequently established the Gay & Lesbian Fund for Colorado, which has given $100 million to cultural institutions and other causes.
He also started OutGiving, which holds an annual donor meeting to raise money and coordinate targets for state and local gay-rights campaigns. At its next gathering, on April 30, OutGiving will launch a new organization, Freedom for All Americans, to pursue antidiscrimination laws in states that do not provide bias protection to LGBT residents.
