Howery then rejoined Thiel in 2004 at Clarium Capital Management, where he served as vice president of private equity, as well as a member of the research and trading teams.

[citation needed] In March 2012, the World Economic Forum named Howery a Young Global Leader,[8] a community of “socially-minded men and women selected under the age of 40, who operate as a force for good to overcome barriers that elsewhere stand in the way of progress.

[10] In 2005, Howery and Thiel, along with fellow PayPal alumnus, Nosek, started Founders Fund, a San Francisco-based venture capital firm with over $3 billion under management, where he served as co-founder and partner.

[16][17] In his confirmation hearing, Howery stated his priorities as ambassador would include pursuing expanded economic and trade relationships, advancing mutual security commitments, and promoting science, technology and entrepreneurship opportunities.

[24] President Trump later praised Howery's leadership on increasing defense, security, and economic cooperation between the United States and Sweden, saying "he served our [n]ation brilliantly," as an ambassador.

[25] Howery strongly advocated for clean 5G technology,[26] promoting the official U.S Department of State position that encourages the use of equipment made by Swedish manufacturer Ericsson and asserts that Huawei-made products are a security risk to democracies.

Howery met with senior Swedish officials on 5G security in September, 2020,[27] and Sweden subsequently announced a ban on equipment from telecommunication companies Huawei and ZTE in its 5G network.

[34] He led efforts by U.S. Embassy Stockholm to assist Swedish manufacturer Getinge with supply chain issues, helping it to expand production of ventilators for the benefit of COVID-19 patients in the United States and around the world.

"[50] President-elect Donald Trump announced Howery as his choice to be Ambassador Extraordinary and Plenipotentiary of the United States of America to the Kingdom of Denmark on December 22, 2024.
