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.

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 Cuts Staff After Major Reorg
The Trade Desk announced workforce reductions of less than 1% of its employees, with headcount around 3,900. A company spokesperson confirmed the layoffs to AdExchanger, and the firm will hold an all-hands meeting at 12:30 pm ET to discuss the news with remaining staff. The company has hired nearly 1,000 people this year, including dozens at the senior leadership level. Jud Spencer, lead engineer for more than 12 years, left The Trade Desk in November. The layoffs come roughly one year after a major reorganization described by CEO Jeff Green as the biggest in the company’s history, a restructuring aimed at aligning client-facing teams amid growing competition from Amazon and Google.
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.
