He attended Concord-Carlisle High School in Concord and graduated in 2006. He then enrolled at Duke University, where he studied Computer Science and Economics and joined the Sigma Alpha Epsilon fraternity.
In May 2008, he conducted research on self-assembling DNA nanostructures at the university. He graduated in 2010 with a B.S., earning honours and departmental distinction in both fields.
Career
After graduating from Duke University in 2010, Frederick Ernest Ehrsam III, known as Fred Ehrsam, joined Goldman Sachs in New York as a foreign exchange trader.
He bought his first Bitcoin in 2011 and soon became convinced that ordinary people needed a simpler way to buy and store digital currency. He came across an early prototype of Coinbase on the Bitcoin subreddit built by Brian Armstrong, and the two connected by email before meeting in person in San Francisco in 2012.
Ehrsam left Goldman Sachs that year to co-found Coinbase with Armstrong, and he became the company’s first President, a role he held until 2017. He joined its board of directors in March 2013 and remains a director.
Under his early leadership, the platform grew into the largest cryptocurrency exchange in the United States. In 2013, Time named him to its “30 Under 30” list of world changers, and Forbes also placed him on its “30 Under 30” list at the age of 25.
His alma mater reportedly invested in the Coinbase Series C round in 2015 after he reached out to Duke University. Coinbase went public on Nasdaq through a direct listing in 2021, when he held roughly 8.9% of the company. In May 2022, he bought $75 million worth of Coinbase shares after the stock dropped on weak earnings.
In late 2017, Ehrsam moved away from day-to-day operations at Coinbase to focus on building blockchain-based applications. In 2018, he co-founded Paradigm, a crypto-focused investment firm, with Matt Huang, a former Sequoia Capital investor.
The two served as co-managing partners, and the firm raised a $2.5 billion fund in 2021, the largest crypto-focused venture fund at the time. Paradigm backed protocol and infrastructure projects including Uniswap, Tendermint, the core team behind Cosmos, and the tBTC network. Ehrsam also wrote widely on governance, NFTs, and crypto-native insurance for the firm’s research and essays.
On October 24, 2023, Ehrsam announced on X that he was stepping down as managing partner at Paradigm to pursue other interests, including biotechnology, while staying on as a general partner. In 2024, he incorporated Nudge, a neurotechnology startup building non-invasive brain-computer interfaces that use focused ultrasound to influence brain activity, and he serves as its CEO.
The company raised $100 million in Series A funding in 2025 and hired former Neuralink employees. He now serves as a senior advisor at Paradigm and sits on the President’s Council of Advisors on Science and Technology. Beyond crypto, he has been an early investor in OpenAI, Anthropic, Anduril, SpaceX, and other frontier technology companies.
