Stagwell Hires Nicole Souza as North America Growth Chief
Vice President JD Vance and Treasury Secretary Scott Bessent held a private call with several leading tech executives to question the security posture and safe deployment of large language models ahead of Anthropic’s limited rollout of its new Mythos model. Participants included Anthropic’s Dario Amodei, Google’s Sundar Pichai, OpenAI’s Sam Altman, Microsoft’s Satya Nadella, CrowdStrike’s George Kurtz and Palo Alto Networks’ Nikesh Arora. Officials discussed how to respond if models scale in ways that favor attackers. Anthropic told U.S. officials it had briefed them on Mythos Preview’s offensive and defensive cyber capabilities and limited the model’s launch to trusted partners (including Apple, Google, Microsoft, Nvidia, Palo Alto Networks and CrowdStrike). Separately, Bessent and Federal Reserve Chair Jerome Powell convened major bank chiefs to assess potential systemic risks. Anthropic remains blocked from Department of Defense contracts while related legal challenges continue.

Stagwell Media Launches as Global Media Agency
Stagwell, the challenger agency network, has launched a new global media agency, Stagwell Media, which will be built on the foundation of its existing performance marketing agency Assembly. The new agency will be led by Liz Rutgersson, who recently joined as Assembly's CEO. Rutgersson emphasized that Stagwell Media is not an umbrella brand and that other Stagwell agencies like Crispin and Gale will continue to operate independently. The launch comes as competitors like WPP have consolidated their media offerings into umbrella brands. Rutgersson stated the new agency aims to fill a gap between traditional, complex agency models and fragmented specialist providers, with a strong focus on agentic AI and speaking to machines, not just human audiences. The announcement was made during Advertising Week New York.
