Byju’s major shareholders, including Prosus and Peak XV Partners, voted on Friday to oust its founder as chief executive officer, escalating a battle over the fate of the once high-flying online tutoring startup that is fighting to remain in business.

Byju’s rejected the resolutions, which also sought to remove Byju Raveendran from the board of the company he had founded in 2015, the company said in a statement on Friday.

“The resolutions passed during the recently concluded extraordinary general meeting – attended by a small cohort of select shareholders –are invalid and ineffective,” the statement added.

A spokesperson for Prosus declined to comment, while Peak did not immediately respond to a request for comment.

The vote sends another clear signal of displeasure with the once-celebrated entrepreneur, who boycotted the meeting. It is an unusual twist in a long-running dispute between a company once counted among India’s most valuable startups and a clutch of influential investors that helped bankroll its pre-COVID ascent.

The shareholders’ decision came after an unruly hours-long Zoom call for investors and management on Friday that several Byju’s employees tried to crash, according to two people who attended. Several times during the meeting, unknown participants tried to disrupt the proceedings with whistles and other loud noises, the people said, asking not to be identified discussing a private call.

Online education pioneer Byju’s and its creditors have been mired in a prolonged restructuring conflict after the firm missed an interest payment on a $1.2-billion loan. A unit of the company was put into bankruptcy in the US after the default.

Mr Raveendran, whose ascent from a tutor to the leader of the company once valued at $22 billion captivated a nation then enamoured of charismatic tech entrepreneurs, is taking increasingly desperate measures to keep the business afloat after expanding too rapidly during the pandemic. Byju’s was caught off-balance after demand for online tutoring dropped off as schools reopened.

Some board members have resigned and Mr Raveendran has pledged his home as well as those owned by his family members to raise money for employees’ salaries. It is also selling new stock at a discount of more than 90 per cent from its previous funding round to raise capital.
