The trio leading the venture all left Tinkoff in the second quarter, soon after Russia's invasion of Ukraine triggered Western sanctions against Russia and after an announcement that Tinkoff's London-listed owner TCS Group Holding was planning to expand in Asia.

Among the men leading the fintech start-up is George Chesakov, who was a co-founder of Tinkoff and had announced a week before the Ukraine invasion that TCS would team up with Swiss payment specialist BPC in the Philippines as part of a $200 million expansion into Asia.

The other two men leading the rival venture are Pavel Fedorov, joint Tinkoff CEO in 2021-22, and Raffy Montemayor, a Filipino who will head the new business in the Philippines.
