Adyen Buys Time With Interim CFO as Product Chief Lands

Adyen has opted for an interim finance chief rather than a permanent CFO replacement, naming Hwa Tsao to take over on Sept. 1 as Ethan Tandowsky exits at the end of August.

The Dutch fintech said Tsao, currently Senior Vice President of Group Finance, will become interim chief financial officer, while Gayathri Rajan has been appointed chief product officer effective immediately, according to American Banker.

Adyen names Hwa Tsao interim CFO as Ethan Tandowsky exits

The expected clean succession did not arrive. Instead, Adyen interim CFO duties will go to an internal finance executive while the company works through the handoff from Tandowsky.

Tandowsky is scheduled to leave Adyen at the end of August. That puts the near-term focus on continuity as Tsao steps into the finance role on an interim basis.

Tsao is currently Senior Vice President of Group Finance at Adyen, with prior roles at ServiceNow, HP and Citigroup. That background gives Adyen a finance operator already inside the company, which matters when investors are watching continuity in reporting, margin discipline and capital allocation.

The interim label is the signal. Adyen has named a finance leader for the next stage of the transition, but it has not presented the appointment as a permanent CFO selection.

That is a restrained read, but it still frames the issue clearly: Adyen has bought time, not closed the CFO question.

The before-and-after is narrow but important:

• Before: Tandowsky remains CFO until the end of August.
• After: Tsao becomes Adyen interim CFO on Sept. 1.
• Open item: Adyen has not named a permanent CFO in the supplied announcement.

That keeps investor attention on the transition itself. The first test is whether Adyen can keep the finance function steady while the company decides what the permanent leadership structure should look like.

Gayathri Rajan takes over Adyen product leadership immediately

Adyen’s second move is not a finance succession issue, but it lands at the same time and makes this a broader leadership reset. Gayathri Rajan becomes chief product officer immediately.

Rajan previously served as Adyen’s global head of product, overseeing core product design, management and partnership initiatives. She has more than 25 years of experience in fintech product and technology, with prior roles at Google, DriveWealth and Vanguard.

The product role matters because Adyen is not presenting itself as a single-purpose payments processor. Its merchant-facing business depends on product depth, reliability and the ability to connect payments infrastructure with adjacent financial technology tools.

That makes the CPO appointment more than a title change. Rajan is stepping into a formal executive product seat at a time when large merchants expect payments providers to support more use cases, more markets and more complex operational needs.

For XOOMAR readers tracking payments infrastructure, the useful read-through is operational. Product leadership at Adyen now sits closer to merchant tooling, checkout infrastructure, embedded payments and the reliability demands that come with serving large global clients.

That fits a broader set of pressures we’ve covered across payments, including banks pushing harder on AI fraud detection after payments vanish and industry focus on certainty in real-time payments. Adyen’s announcement is company-specific, but the execution burden is familiar: payments firms can’t sell platform breadth if the product organization can’t keep the pieces coherent.

Adyen investors will track the permanent CFO search and product roadmap

The finance question now splits into two tracks. First, how smooth is the handoff from Tandowsky to Tsao by Sept. 1? Second, how long does Adyen take to name a permanent CFO?

Listed fintech companies get little slack on finance leadership changes. Investors want consistent reporting, clear cost control and a credible capital allocation story, especially when a company is expanding its product base and competing for large enterprise merchants.

The timing adds pressure because Adyen is not only managing a CFO transition. It is also lifting Rajan into a formal CPO seat, which makes product execution part of the same leadership story.

XOOMAR analysis: the most important gap in the announcement is not Tsao’s qualifications. It is the absence of a permanent CFO timeline. The interim appointment may give Adyen flexibility, but investors will still look for evidence that the finance function remains steady through the transition.

Rajan’s first test is different. The CPO role will likely be judged by how well Adyen turns its product capabilities into a sharper, more coherent suite for merchants. In payments, breadth only helps if clients can adopt products without creating more operational complexity.

There is also a management signal here. By naming Rajan immediately while making Tsao’s CFO role effective later, Adyen is moving faster on product structure than on permanent finance succession.

The next triggers are straightforward: any update on the CFO search, commentary around the Sept. 1 transition, and investor-facing detail on the product roadmap. If Adyen can show finance continuity and product focus at the same time, the interim CFO label becomes less disruptive. If the permanent search drags on without explanation, that label will draw more scrutiny.

The Bottom Line

• Adyen is prioritizing continuity by promoting an internal finance executive to interim CFO.
• The interim appointment leaves the permanent CFO question unresolved for investors.
• Gayathri Rajan’s immediate appointment as chief product officer signals a parallel focus on product leadership.
