Invicta Phoenix Series was a mixed-martial arts event featuring the first in a new series of tournaments produced by Invicta FC for each weight division. The Phoenix Series features a one-night tournament format in which the quarter-final and semi-final bouts are one-round contests, and the tournament final is a three-round bout. Tournament participants are matched up by random draw. Reserve bouts for the tournament are one-round contests, and are classified as exhibitions. Bonuses are awarded for each finish, and the fighter with the fastest finish in the quarterfinals may choose their opponent for the next round from among the other semi-finalists.

Invicta FC 19: Maia vs. Modafferi was a mixed martial arts event that was headlined by Jennifer Maia defending her flyweight championship against Roxanne Modafferi. The event's co-main event featured atomweight champion Ayaka Hamasaki defending her title against top contender Jinh Yu Frey.

Invicta FC 22: Evinger vs. Kunitskaya II was a mixed martial arts event headlined by Tonya Evinger defending her bantamweight championship in a rematch against Yana Kunitskaya. The rematch comes after a controversial finish to their first fight, which headlined Invicta FC 20 and was overturned to a no contest. In the co-main event, Invicta atomweight champion Ayaka Hamasaki will move up to strawweight for a fight against former strawweight champion Lívia Renata Souza. A fight between Jinh Yu Frey and Janaisa Morandin was scheduled but canceled two days before the event when Morandin failed to make weight.

Invicta FC 24: Dudieva vs. Borella was a mixed martial arts event originally scheduled to be headlined by Megan Anderson; defending her featherweight championship against Helena Kolesnyk. However, Megan was signed by the UFC. As a result, Invicta bantamweight champion Tonya Evinger would move up to featherweight to replace Anderson in the fight against Kolesnyk. However, Anderson would end up pulling out of her UFC fight which then led to Evinger stepping in for that fight, removing her from this event. Due to the change, Helena Kolesnyk received a new opponent in Pam Sorenson while the previous co-main event of Milana Dudieva vs. Mara Romero Borella was moved up to become the new main event. A bout between Yana Kunitskaya and Raquel Pa'aluhi was removed with plans to reschedule due to Kunitskaya suffering an injury. The fight between Mallory Martin and Tiffany Masters was cancelled the day before the event due to medical issues.
