A statement from Logitech G, a division of preipherals maker Logitech, claimed the two companies were the leaders for headsets, mice, keyboards and streaming webcam for PC and console gamers.
The acqusition means that Logitech G ANZ will now be the sponsor for the Mindfreak Esports Organisation.
Logitech G and Astro Gaming ANZ category manager Daniel Hall said: “We are really excited to see esports, gaming and streaming grow rapidly in ANZ.
"Welcoming Mindfreak as apart of the Logitech G ANZ team, allows us to explore how we can excite fans and how we can help develop esports in ANZ”.
Mindfreak said it was experiencing major growth by expanding into the PC genre by launching its first Overwatch team which previous competed under the name Sandbaggers.
Mindfreak Esports owner and chief executive Albert Nassif said: "With the success Overwatch has had internationally with the Overwatch League, the hype around the game continues to grow.
"Overwatch is no longer the new kid on the block in esports and has established a solid foundation and fanbase on which it will only continue to build and grow.
“As an organisation, Mindfreak has grown from strength to strength and with every new team we welcome to the family, we continue to support this.
"With our acquisition of the 'Sandbaggers' into the Overwatch roster we welcome a team that fought their way out of the Open Division, through Trials and into the Contenders.”
