Sequoia partner Stephanie Zhan launches early-stage AI fund, with Sequoia and Jeff Dean among the LPs
Sequoia partner Stephanie Zhan posted on X on October 22, 2026, saying that she is launching a new early-stage AI fund focused on making bold bets with founders from the company-formation stage, far ahead of consensus. The fund’s limited partners will include Sequoia, Jeff Dean, Sachin Katti, Philip Wong (her Stanford professor and TSMC chief scientist adviser), among others.
Zhan said that she will continue to serve as a Sequoia partner and will continue to serve on its board on behalf of Sequoia. She has been with Sequoia for 11 years and is the youngest investor the firm has ever hired. She said that in the current AI era, research and products often advance in parallel, breakthroughs can quickly open markets or accelerate businesses, some companies at the early stage require substantial capital and computing power, while others reach meaningful scale with very small teams. She cited early collaborations with companies such as Skild AI, Reflection AI, and Ricursive AI, and emphasized believing in founders’ technical insights with extreme conviction from the very beginning.

Zhan’s new fund is positioned for early bets at the company-formation stage, explicitly emphasizing being “far ahead of consensus.” She retains her Sequoia partner role and continues to serve on the related board, making the new fund parallel to, rather than completely separate from, the existing platform. The list of limited partners includes Sequoia itself, Jeff Dean, and Philip Wong, who is associated with TSMC, indicating both capital and industry-network sources.
In the article, she reviews her 11 years since joining Sequoia and points out that in the current AI era, the pace of research and product development is accelerating, while capital and compute needs are diverging. The cited cases of Skild AI, Reflection AI, and Ricursive AI all involve the process from technical insight to commercialization and partner introduction, used to illustrate her concrete way of getting involved early.
Zhan presents “believing in founders’ technical insights from the very beginning” as her core approach, and says that sustained support is needed in areas such as compute, capital, hiring, and customer acquisition. The fund has not disclosed its name, size, or specific investment terms, and the relevant information is based on her own statements.
