Sequoia Capital managing partner, Moritz’s protégé, and the Sequoia partner who invested in TrialSpark from the seed round, joined the Formation Bio board, wrote the institutional endorsement of Altman’s YC presidency, and sits on the boards of Airbnb, DoorDash, and Citadel Securities.
Bio
Alfred Lin is a Taiwanese-American venture capitalist who has served as managing partner of Sequoia Capital since 2025, co-leading global investment operations alongside Pat Grady. He joined Sequoia in 2010 after a career defined by a single lifelong friendship: with Tony Hsieh, co-founder of LinkExchange and CEO of Zappos, whom he met at Harvard. [1][2][3]
Lin’s career path traces through every company he and Hsieh built together. At Harvard, Lin famously bought whole pizzas from Hsieh’s student pizza business and resold them by the slice to his roommates — a story Hsieh told for years as evidence of Lin’s instinct for margin. After Harvard (BA Applied Mathematics) and Stanford (MS Statistics, dropped out of PhD program), Lin joined Hsieh at LinkExchange as CFO. Sequoia invested; the company sold to Microsoft for $265M in 1998, returning Sequoia 17x in 17 months. [2][3][4]
Lin and Hsieh then co-founded Venture Frogs, an incubator and seed fund that invested in Ask Jeeves, OpenTable, Tellme Networks, and Zappos. Lin served as VP of Finance at Tellme (acquired by Microsoft) from 2001 to 2005, then joined Zappos as COO, CFO, and Chairman. Under his operational leadership, Zappos was acquired by Amazon in 2009 for $1.2 billion. [2][3][5]
Throughout this trajectory, one person was constant: Michael Moritz. In Lin’s own words on sequoiacap.com: “Michael Moritz had been our Sequoia partner at LinkExchange and we chose to work with him again at Zappos. He was a mentor to me and the rest of the management team.” [6] Moritz mentored Lin from the late 1990s through Lin’s arrival at Sequoia as a partner in 2010 — a relationship spanning over a decade before Lin began making investments on Sequoia’s behalf.
Tony Hsieh died in a house fire on November 18, 2020 — during the Project Covalence operational window. He was 46. Lin described the loss publicly while navigating one of his most successful professional periods: Airbnb and DoorDash both IPO’d in December 2020, both with Lin on their boards. [7]

Network Function: The Moritz Protégé as Institutional Bridge
Lin’s network function in the Altman investigation is specific and documented: he is the Sequoia partner who bridges Moritz’s institutional authority to the operational deal-making layer.
The Blog Post — February 21, 2014
On the same day Paul Graham published “Sam Altman for President” announcing Altman as YC’s new president, Lin published a Sequoia Capital blog post congratulating Altman on the appointment. The post reveals: [8]
“We were fortunate to have gotten to know Sam when he founded Loopt, where we became an early business partner and investor. He was still underage when we proposed going out for celebratory drinks after signing the term sheet.“
This establishes: (a) Sequoia’s relationship with Altman dates to his teenage years, (b) Lin was personally involved in the Loopt deal (or at minimum writes as if the institutional “we” includes him), and (c) the Sequoia institutional endorsement of Altman’s presidency was coordinated to publish the same day as Graham’s announcement.
The post also names the YC-Sequoia portfolio overlap: “Drew and Arash at Dropbox, Patrick and John at Stripe, and Brian, Joe, and Nate at Airbnb” — the same people Altman would place on his Board of Overseers four months later (June 2014). Sequoia’s portfolio and Altman’s governance circle were substantially the same people. [8]
The TrialSpark Seed — September 28, 2017
Lin was the named Sequoia partner on TrialSpark’s seed round, alongside Thrive Capital (Josh Kushner). [9] This is the earliest institutional money into the company that would:
- Operate Project Covalence (2020)
- Receive Altman’s $1M nonprofit grant (FY2020)
- Rebrand to Formation Bio (2023)
- Launch Muse with OpenAI and Sanofi (2024)
- License gusacitinib to Sanofi for €545M (2025)
Moritz’s protégé placed the seed bet. Moritz himself is named as a personal investor in subsequent reporting. The mentor-protégé relationship means the TrialSpark investment wasn’t just Lin’s call — it carried Moritz’s institutional weight.
The Formation Bio Board — 2024
Lin joined the Formation Bio board at the Series D round (July 2024, $372M, led by a16z). [9] Seven years from seed to board seat. He now sits alongside:
- Scott Kupor (Managing Partner, a16z) — board member
- Michael Moritz (Senior Advisor, Sequoia Heritage) — his own mentor
- Kareem Zaki (Partner, Thrive Capital/Kushner) — board observer
The entire governance structure of Formation Bio is Sequoia + a16z + Thrive (Kushner) + Altman’s personal stake. Lin is the Sequoia representative who has been present from seed to board.
Investigative Findings
Finding 1: The Moritz Mentorship Chain
The Lin-Moritz relationship is not just biographical color — it’s a structural feature of how the network operates. Moritz mentored Lin from 1996 (LinkExchange) through 2010 (Zappos/Sequoia). When Lin joined Sequoia as a partner, he brought Moritz’s institutional perspective and relationship network into the next generation of deal-making. [6]
When Lin placed the TrialSpark seed (2017), wrote the Altman endorsement (2014), and joined the Formation Bio board (2024), these were not independent decisions by an independent partner. They were decisions by Moritz’s protégé, carrying the weight of a mentorship relationship that spans nearly three decades. The mentor doesn’t need to be in the room if his protégé is making the calls.
Finding 2: Same-Day Institutional Endorsement
The February 21, 2014 blog post was coordinated with Paul Graham’s announcement. [8] Sequoia’s institutional endorsement — written by Moritz’s protégé — published the same day as the YC founder’s announcement. This is not coincidental timing; it’s coordinated narrative management. Two institutions (YC and Sequoia) with interlocking financial interests (Sequoia invested in YC in 2009) announce the leadership transition simultaneously, presenting it as universally endorsed.
Finding 3: The Airbnb Board Timing
Lin joined Airbnb’s board in 2012 — the same year as the Loopt-Green Dot acquisition. [7] Brian Chesky specifically asked Sequoia for Lin to sit on Airbnb’s board. This means: in 2012, McAdoo was leaving the Airbnb board orbit (departed Sequoia January 2013), and Lin was entering it. The Sequoia-Airbnb governance relationship transferred from one partner to another seamlessly.
Finding 4: FTX Investment
Lin’s Sequoia investments include FTX, which was written down to $0 in November 2022. [10] Golden.com lists “FTX” among Lin’s partner investments through Sequoia. The $214M FTX write-down occurred while Lin was already on the TrialSpark/Formation Bio trajectory (seed investor since 2017). The same partner whose due diligence missed FTX’s fraud was the Sequoia representative on the company that operated Project Covalence.
Finding 5: The Harvard-Hsieh-Moritz-Altman Chain
Lin met Hsieh at Harvard. Hsieh and Lin built LinkExchange. Moritz was their Sequoia partner. Moritz mentored Lin. Lin joined Sequoia. Lin endorsed Altman’s YC presidency. Lin seeded TrialSpark. Lin joined Formation Bio’s board. The chain from a Harvard pizza scheme to a $1.8B AI-native pharma company runs through one continuous mentorship relationship — Moritz → Lin — with Altman as the recurring beneficiary of Lin’s institutional endorsements and investment decisions. [2][3][6][8][9]
Finding 6: The “Underage” Detail
Lin’s 2014 blog post reveals that Altman was legally underage (under 21, US drinking age) when Sequoia signed the Loopt term sheet — meaning the investment was made when Altman was 19 or 20. [8] Sequoia’s institutional relationship with Altman originates from a period when he was too young to legally drink alcohol. This contextualizes the power dynamic: a teenager negotiating with one of Silicon Valley’s most powerful firms, a relationship that has since grown into a network controlling billions in assets. The mentee became the network’s most visible node; the mentors retained institutional control.
Board Positions and Investment Overlaps
| Company | Lin’s Role | Altman Connection | Overlap Type |
|---|---|---|---|
| TrialSpark / Formation Bio | Seed investor (2017). Board member (2024). | $1M nonprofit grant (FY2020). $156M Series C co-lead. $19M stake (trial exhibit). | Seed → nonprofit grant → personal investment → board. Full lifecycle. |
| Airbnb | Board member (2012-present). | Personal investor (pre-Sequoia). Reddit content licensing parallels. | Lin replaced McAdoo’s orbit on Airbnb governance. |
| DoorDash | Board member. | YC S13 batch (during Altman’s YC partner period). | YC pipeline → Sequoia board. |
| Sequoia investment (Lin as partner investor per Golden). | 7.6% owner. Helped install Huffman. OpenAI content licensing deal. | Both Sequoia and Altman invested; Altman had governance. | |
| Citadel Securities | Board member. | — | Financial infrastructure. No direct Altman overlap found. |
Nodes / Open Questions
- What was Lin’s role in the TrialSpark seed decision? Was it his independent sourcing, or was it directed/influenced by Moritz? The mentor-protégé relationship means the decision chain is opaque from outside.
- Did Lin have any involvement in or awareness of Project Covalence? As the seed investor, he would have had information rights. Did he receive updates on the OpenResearch grant, the resTORbio collaboration, the nursing home trial outcomes?
- What is Lin’s relationship to the OpenAI investment? Grokipedia lists OpenAI among his investment leads alongside Airbnb and DoorDash. If Sequoia invested in OpenAI (or OpenAI’s for-profit arm) through Lin, he would have financial interest in BOTH OpenAI and Formation Bio — the two companies that launched Muse together.
- The Hsieh death timing (November 18, 2020): Lin’s lifelong friend and business partner died during the exact window of Project Covalence’s activity, the OpenResearch grants, and the Libertas Bio incorporation. This is documented as context, not connection. But the personal disruption may have affected Lin’s oversight of Sequoia portfolio companies during this period.
- Citadel Securities board seat: Lin sits on the board of Citadel Securities (Ken Griffin). What is the relationship between Citadel’s financial infrastructure and any Sequoia/Altman portfolio companies? Market-making, trading, liquidity provision?
- The April 2016 “merger” joke: Altman’s YC blog post joking about a Sequoia-YC merger specifically names “Alfred Lin from Sequoia.” This is a primary-source document showing Lin’s name was in Altman’s mouth when discussing the YC-Sequoia relationship — publicly, on the record, in Altman’s own voice.
- Lin’s 2025 elevation to managing partner: He now co-leads Sequoia’s global operations. How does this affect the Formation Bio board relationship? A managing partner has more institutional weight than a regular partner — his Formation Bio governance role now carries Sequoia’s full institutional authority.
