Prantoz Foundation is a non-registered Community-Based Organization (CBO) that was first started unofficially in 2004 as a self-help group named "Vivid Rainbow" for the marginalized SOGIESC population in Khulna division.

Currently, it has a youth wing named "Prantoz Jubo Songho" which is a sister concern of the Prantoz Foundation. It has an Advisory Board and an Executive Board to run the organization properly. The Bengali/Bangla word "PRANTOZ" means "born from the edge", “born from the margin or periphery”, “originated from the margin” or "originated from the edge". The word "PRANTO" means "edge" or “periphery”. The Bengali word “PRANTO” is also called "Margin" in English. The most marginalized or poorest people who are neglected and oppressed by society, state, family, religion, law, etc. are called "Marginalized People" (People who are socio-economically and politically excluded and disadvantaged; people who are from the Margin or the Edge of the Society). Bengali term “PRANTIK JONOGOSHTTHI” means “marginalized people". The people who are pushed to the very end of society by the majority of the people in the society while being tortured and neglected or discriminated against; the people leaning against that wall are the "Marginalized People". The grassroots are called Marginalized people too.
