The Bisexual Resource Center was founded in 1985 by a group of bi activists after a regional conference. First named the East Coast Bisexual Network, it became a 501(c)3 in 1989 and was renamed in the mid-90s. The BRC is the oldest national bi+ organization in the U.S. that advocates for bisexual visibility and raises awareness about bisexuality throughout the LGBT and straight communities.

Bisexual.org is a project of The American Institute of Bisexuality (AIB) and the Bisexual Foundation. They are a 501(c)(3) public charity that supports and sponsors projects likely to promote understanding and visibility about bisexuality through education, research, training, and media outreach.

The American Institute of Bisexuality encourages, supports and assists research and education about bisexuality, through programs likely to make a material difference and enhance public knowledge, awareness and understanding about bisexuality.
