The Trade Desk CFO Departs; Interim CFO Appointed
The Trade Desk announced that CFO Alexander Kayyal has departed after six months, marking the second abrupt finance‑chief change within a year. The company appointed veteran Tahnil Davis — previously Chief Accounting Officer and a near‑decade employee — as interim Chief Financial Officer while it searches for a permanent replacement. An SEC filing confirms the ongoing search, and the company said Kayyal will remain on the board until the next annual shareholder meeting. Investors reacted negatively, with shares falling about 7% in morning trading. The Trade Desk reaffirmed its fourth‑quarter revenue guidance of $840 million. The leadership instability raises investor confidence risks for the DSP as it navigates competitive and market pressures in the adtech sector.
Leadership turnover at a major DSP can undermine investor confidence, affect stock performance and strategic execution; The Trade Desk is a significant adtech vendor, so CFO instability has meaningful but not industry‑shifting implications.

Inside The Trade Desk Executive Exodus
The Trade Desk has experienced significant executive turnover over the past year, including multiple CFO changes and the departure of several senior executives and board members. At least four board members — including Lise Buyer, Gokul Rajaram and Kathryn Falberg — have left since March. Departing executives have cited frustration with the company’s rising take rate and internal leadership decisions under CEO Jeff Green. Chief Strategy Officer Samantha Jacobson is reported to be leaving for a role at OpenAI. Jarod Schneider, who led technical account management, also left after 14 years. Former Trade Desk executives are landing across the industry at organizations including OpenAI, eMarketer, Index Exchange, DeepIntent and StackAdapt.
The Trade Desk Names Nate Olmstead CFO
The Trade Desk announced Nate Olmstead will become its chief financial officer, joining the company on July 9 and reporting to CEO Jeff Green. Olmstead is the company’s fourth finance chief in roughly a year, taking the role after a period of executive departures, board turnover and investor scrutiny. He previously served as CFO of Penguin Solutions, was CFO at Logitech, and held senior finance roles at Hewlett-Packard and Hewlett Packard Enterprise. The appointment follows the termination of former CFO Alex Kayyal earlier this year and comes as The Trade Desk faces competitive pressure from Amazon and Google, agency partner concerns and a stock that has fallen about 70% over the past year.
The Trade Desk Faces Turmoil as Engineering Leader Exits
The Trade Desk announced that Jud Spencer, one of its longest-tenured engineering leaders, left the company with his last day on November 21. Spencer contributed to engineering leadership, supply-side inventory sourcing, and media quality assessments, and participated in industry standards work including the OpenRTB Transaction ID and collaborations with Prebid and IAB Tech Lab. His departure comes amid a broader executive overhaul at The Trade Desk, which has seen multiple C-level changes this year, including CRO Jed Dederick stepping down and being replaced by Anders Mortensen; CFO Laura Schenkein stepping down and being replaced by Alex Kayyal; and COO Vivek Kundra joining the company in March. The move follows ongoing tensions between The Trade Desk and Prebid.org regarding universal Transaction IDs, and the launch of OpenAds, a fork of Prebid mandating Transaction IDs. The company notes are cautious about commenting on Spencer’s departure.
