Adyen appoints interim CFO, chief product officer

• Key insights: Adyen said that Senior Vice President of Group Finance Hwa Tsao would become the company's interim chief financial officer following the departure of CFO Ethan Tandowsky at the end of August. Separately, Gayathri Rajan will assume the role of chief product officer
• What's at stake: Tandowsky said he was departing the fintech in May for an opportunity outside of the payments industry. Tsao, who joined Adyen in 2025, is likely serving as a stop-gap while the company does a more comprehensive search for a full-time finance chief, according to Keefe Bruyette & Woods. 
• Forward look: Tsao will become interim CFO on Sept. 1; Rajan's promotion is effective immediately. 

Adyen has temporarily found a replacement for Chief Financial Officer Ethan Tandowsky, who is slated to depart the fintech at the end of August for an opportunity outside of the payments industry. 

Senior Vice President of Group Finance Hwa Tsao will become the company's interim CFO when Tandowsky takes his leave. Separately, Gayathri Rajan will assume the role of chief product officer, effective immediately. Both Tsao and Rajan will report to Adyen's co-CEOs.

The Dutch fintech also said it closed its two pending acquisitions of Berlin-based loyalty and incentive platform Talon.One and business billing tech firm Orb. Those purchases were notable because they marked the fintech's first two acquisitions in the company's 20-year history and helped Adyen expand into new revenue streams. 

"Aligning our executive leadership with this multi-product reality is a natural step forward," Adyen co-CEO Ingo Uytdehaage said in a statement. "Gayathri's appointment to CPO recognizes her instrumental role in driving our product strategy and ambitions over the past three years, a momentum further amplified by the additions of Talon.One and Orb." 

Rajan has more than 25 years experience in fintech product and technology, and previously was Adyen's global head of product, where she oversaw the company's core product design, management and partnership initiatives. Prior to joining Adyen, Rajan held roles at Google, DriveWealth and Vanguard. 

Tsao, who joined Adyen in November 2025 following stints at ServiceNow, HP and Citi, is serving as a stop-gap while the company does a more comprehensive search for a full-time finance chief, according to Keefe Bruyette & Woods.

"We believe the decision to make Mr. Tsao an interim pick is likely a strategy that allows the company enough time to run a comprehensive search in order to find the right CFO candidate," according to KBW. "We would not read too much into this news outside of the point above." 

Adyen has been working to expand its reach. The company has been putting its banking license to work with a new treasury product that combines payments, liquidity management and payouts, and has also expanded its embedded payments partnership with Uber to airport kiosks.
