o4g.org
Nonprofit names appear on grant applications, partner lists, conference programmes and report covers, always surrounded by other organisations’ branding. A short name holds its own in that crowd; a long one gets abbreviated by someone else.
O4G reads as opportunity for girls, organising for good, or outcomes for growth. Girls’ education and empowerment is one of the largest funded causes in global philanthropy with dedicated programmes at every major foundation, and every funder in that sector would read the name correctly without explanation.
Organising for good suits a broader civic or community organisation and carries the right activist register.
Fixed supply, established convention, correct extension.
The name is available. Offers welcome.
