The ReBalance scheme is targeted at UK-based, core female identified bands, musicians or solo artists.
The three successful acts - Luna, Lady Sanity and Martha Hill - will benefit from access to recording time in Old Chapel studios and a slot at a Festival Republic or Live Nation event.
Birmingham rapper Lady Sanity has already been confirmed for Wireless Festival this year.
Since launching in 2017 as part of an effort to address gender imbalance, there have been hundreds of nominations and 13 finalists.
Following their participation in the scheme, Æ Mak have been booked to play Reading & Leeds Festivals, as well as signing to Primary Talent.
