The investment group led by Barcelona defender Gerard Pique has purchased FC Andorra, who play in Spain's lower leagues.
Pique said in a statement that his investment group, Kosmos, have completed their takeover after club members approved the sale.
FC Andorra, founded in 1942, currently play in Spain's fifth tier against clubs in Catalonia, playing as high as the third tier in the 1980s and 1990s.
The acquisition of FC Andorra is the latest business move by Pique.
Kosmos were given approval by the International Tennis Federation to revamp the Davis Cup, transforming it into a season-ending tournament held in one venue as opposed to the current format which spreads ties out over months in different countries.
Pique has also launched business ventures in esports, video games, eyeglasses, isotonic drinks and organic hamburgers.
Mundo Deportivo reported that Pique could also retire from football in 2020 to focus on running for Barcelona's club presidency in 2021.
