Key facts

Early Life: Video Games and Computing

Graduating from Duke University

Ehrsam graduated from Duke University in 2010 with honors and departmental distinctions in both economics and computer science. Coinbase’s corporate filings describe his degree as a B.S. in Computer Science and Economics and use his full name, Frederick Ernest Ehrsam III.⁠[2][3]

Foreign Exchange Trading at Goldman Sachs

Co-Founding Coinbase

Ehrsam co-founded Coinbase in 2012 and served as President from November 2012 to January 2017. The company announced his arrival in January 2013, a publication date distinct from the start of his tenure. He became a director in March 2013.⁠[3][4][1]

Downturns and Funding Pressure

In a retrospective published in 2021, Ehrsam wrote that Coinbase temporarily suspended customer purchases during a surge in demand in 2013 because it lacked working capital. Industry downturns over the following years also strained the team. He recalled raising funding early, maintaining focus and retaining cash, and rejecting a suggestion in 2015 to pivot toward private blockchains for banks. These details reflect his later account.⁠[5]

Co-Founding Paradigm

Ehrsam co-founded crypto investment firm Paradigm in 2018. Coinbase’s 2023 filing dates the start of his role as co-founder and Managing Partner to June 2018. Paradigm’s investment and research interests encompass crypto companies, protocols and related technologies.⁠[3][2]

Sharing Lessons on Cycles and Addressing Graduates

In March 2021, Ehrsam published Surviving Crypto Cycles, discussing how startup teams can respond to industry volatility through stress testing, cash reserves and maintaining their core direction. The essay presents his experience and views, rather than a guarantee of future market returns.⁠[5]

On May 2 that year, he addressed Duke’s economics graduates in a commencement video, encouraging curiosity. The university subsequently published an account of the address and a link to the video.⁠[2]

Reducing Day-to-Day Management at Paradigm

In October 2023, Ehrsam announced a transition from Managing Partner to General Partner at Paradigm, reducing management duties while continuing investment, research, portfolio support and crypto policy work. The Block’s account of his public post said he had supported biological research for several years and wanted to devote more time to it. Paradigm’s subsequently updated biography lists him as Co-Founder and Senior Advisor.⁠[6][4]

Nudge’s Technology and Funding

Ehrsam is also Nudge’s Co-Founder and CEO. In April 2025, Nudge publicly described its approach to noninvasive brain stimulation and imaging using focused ultrasound. Its initial device used a helmet-like structure compatible with an MRI environment; portable devices for home use remained a future goal.⁠[4][7]

On July 22, 2025, Nudge announced a $100 million Series A led by Thrive CapitalThrive CapitalThrive Capital is an investment firm led by chief executive Joshua Kushner that builds and invests in internet, software and technology-enabled companies, with investments including Cursor and Chai Discovery.

Appointment to PCAST

On March 25, 2026, the White House announced appointments to the President’s Council of Advisors on Science and Technology, including Fred Ehrsam. He also publicly stated on X that he would participate in the council.⁠[9][10]

Coverage of Venezuelan Energy Investment

On September 2, 2026, Venezuela’s foreign ministry confirmed that Primavera Infinita had signed a participation contract for the Budare-Elotes block. A subsequent El Pitazo investigation identified Ehrsam as a co-founder while noting that public information was insufficient to establish his ownership percentage. The government announcement confirmed the company and block but did not disclose his personal equity stake.⁠[11][12]

Stock Trading Plan Adopted

Ehrsam adopted a conditional Rule 10b5-1 plan covering up to 3,866,620 Class A shares converted from his trust’s Class B holdings. Its estimated window runs December 7, 2026–June 7, 2027, with possible earlier termination; it records planned sales, not executions.⁠[14]
