"Yes I have become the member of AAP, have got the confirmation today," Balakrishnan told PTI with his move to dabble in politics coming three weeks after his sudden exit from India's second largest software services exporter.
"They (AAP) have revolutionised politics in this country, I'm fascinated with it," Balakrishnan said.
Announcing Balakrishnan's exit on December 20 as member of the Board and from services of the Company, Infosys had said the resignation is effective December 31, 2013.
Balakrishnan, who joined Infosys in 1991 and later became its chief financial officer, was said to be a top contender to the post of Chief Executive Officer.
In response to a question whether he was looking for a full time political career along with business commitments, he said, "In future, I think so...; I think I will be able to manage both."
Balakrishnan, soon after his exit from Infosys, had said he was waiting for SEBI's approval for his private equity fund, which he has formed along with former Infosys executive Mohandas Pai and former Wipro executive Girish Paranjpe.
To a question on contesting the Lok Sabha elections, he said, "It's too early to say anything about it."
Balakrishnan was also the BPO head at Infosys as well as the chairman of Infosys Lodestone, a global management consultancy firm.
