The institutional anchor of the Altman network — the venture capital firm whose partners sat on both sides of Altman’s first company acquisition, funded the Y Combinator pipeline that built his career, and invested in the company that operated Project Covalence.
Bio
Sequoia Capital is an American venture capital firm founded in 1972 by Don Valentine in Menlo Park, California. Specializing in seed, early, and growth stage investments in technology companies, Sequoia has backed some of the most consequential companies in Silicon Valley history — including Apple (1978), Cisco, Oracle, Google, YouTube, Instagram, WhatsApp, Stripe, and Airbnb. Companies backed by Sequoia have generated over $3.3 trillion in combined market capitalization. [1][2][3]
Valentine, a veteran of Fairchild Semiconductor and National Semiconductor, named the firm after the long-lived sequoia tree rather than himself. He handed leadership to partners Doug Leone and Michael Moritz in 1996, and continued attending partner meetings for another decade until his death in October 2019 at age 87. [3][4]
The firm managed approximately $85 billion in assets under management as of 2022 before a major restructuring. In June 2023, Sequoia announced it would split into three independent entities by March 2024: Sequoia Capital (US and Europe), HongShan (China, led by Neil Shen), and Peak XV Partners (India and Southeast Asia). The split was driven by geopolitical tensions, portfolio conflicts, and the growing independence of regional teams. [5][6][7]
Sequoia’s current managing partner (officially titled “steward”) is Roelof Botha, a former PayPal CFO who joined the firm in 2003 and made early investments in YouTube, Instagram, and Square. Botha has navigated the firm through the FTX write-down ($214M to zero in November 2022) and the global restructuring. [8][9]
In this investigation, Sequoia’s significance is not as a single actor but as the institutional infrastructure through which network deals flow. Through partners Michael Moritz and Greg McAdoo, Sequoia held positions on both sides of Altman’s first company sale (Loopt → Green Dot), built the institutional bridge between Y Combinator and Silicon Valley’s capital markets, and invested in TrialSpark — the company that received Altman’s nonprofit grant and became Formation Bio.

The Sequoia-YC Pipeline
Sequoia’s relationship with Y Combinator is the institutional backbone of the Altman network. The firm didn’t just invest in YC companies — it invested in YC itself, placed partners on YC company boards, and built a deal-flow pipeline that generated returns for both institutions while concentrating governance in overlapping hands.
Timeline
| Date | Event | Significance |
|---|---|---|
| 1995 | Moritz invests in Yahoo. Graham founds Viaweb. | Careers intertwined — Yahoo acquires Viaweb 1998. Graham and Moritz in overlapping orbit for three decades. [11] |
| 2005 | Graham co-founds Y Combinator. Loopt in first batch (S05). | Altman enters the network. |
| 2006 | Sequoia Series A in Loopt ($5M with NEA). McAdoo joins Loopt board. | McAdoo’s first consumer mobile deal — notable departure from his hardware portfolio (Isilon, PowerFile, Achates). [11][12] |
| 2008 | Altman personally invests in Airbnb (YC W08) with Graham ($100K). | Personal investment established before institutional. |
| 2009 | McAdoo leads Sequoia’s $2M investment in YC itself. McAdoo meets Airbnb through Graham at YC Startup School. Sequoia invests $585K seed in Airbnb. | McAdoo is now simultaneously: Sequoia partner, YC liaison, Loopt board, Airbnb pipeline. Governance concentration. [11][12] |
| 2010 | Sequoia leads YC’s second fund. McAdoo leads $600K Airbnb seed. McAdoo joins Airbnb board. | One of venture capital history’s greatest returns — pennies per share. [12] |
| 2011 | Moritz joins Stripe board (YC-introduced by Graham). Altman becomes part-time YC partner. | Graham has now facilitated two Sequoia board placements: McAdoo → Airbnb, Moritz → Stripe. [11] |
| 2012 Mar | Loopt acquired by Green Dot for $43.4M. McAdoo on seller board. Moritz on buyer board. | Same partnership on both sides. VentureBeat: “marriage of convenience orchestrated by joint investor Sequoia.” [13][14] |
| 2013 Jan | McAdoo departs Sequoia. | Four-year gap before founding Bolt (2017). |
| 2013 Jun | Moritz joins Instacart board (YC-introduced). | Third YC-to-Sequoia board placement. |
| 2014 | Altman becomes YC president. | Institutional control over the pipeline McAdoo built. |
| 2017 Sep | Sequoia (Moritz) seed investment in TrialSpark (LabNook). Thrive Capital (Kushner) co-invests. | Sequoia enters the TrialSpark cap table — the company that will operate Project Covalence and become Formation Bio. [15] |

Investigative Findings
Finding 1: Both Sides of the Loopt-Green Dot Acquisition
The $43.4M acquisition of Loopt by Green Dot Corporation (March 2012) is the foundational self-dealing event in this investigation. Sequoia Capital held positions on BOTH sides:
Seller side: Greg McAdoo — Sequoia partner, Loopt board member since 2006 (representing Sequoia’s Series A investment).
Buyer side: Michael Moritz — Sequoia partner, Green Dot board member since 2003 (nine years before the acquisition).
Financial interest: Sequoia received approximately 23.8% of the merger consideration. [13]
No documented recusal. Neither McAdoo nor Moritz has been documented as recusing from the deal review or approval process. The same partnership — with partners on both sides — approved a transaction that rescued a failing investment (Loopt had reportedly declined from “hundreds of thousands” of DAUs to approximately 500 by 2012) at a price ($43.4M for a company with 500 daily users) that protected Sequoia’s LP metrics. [13][14]
Wikipedia’s own characterization: “a deal that was most likely orchestrated as a marriage of convenience by joint investor Sequoia Capital.” [14]
Green Dot never used a single line of Loopt code. The company paid $43.4M for approximately 30 mobile developers, rebranded as “Green Dot Silicon Valley.” [14]
Finding 2: The McAdoo Category Shift
McAdoo’s pre-2006 Sequoia portfolio was hardware and enterprise infrastructure: Isilon Systems (storage), PowerFile (storage), Achates Power (energy), Sentient Networks (his prior CEO role). After 2006, his portfolio shifted to consumer internet and YC-pipeline companies: Loopt, Airbnb, Clustrix, Dropbox. [12]
The category shift coincides precisely with his assignment as Sequoia’s YC relationship partner. This is either: (a) a natural portfolio evolution, (b) a deliberate Sequoia strategy to assign McAdoo to the YC pipeline regardless of his sector expertise, or (c) the YC relationship providing deal flow that pulled him into unfamiliar territory.
By 2009, McAdoo had led three YC-connected deals at Sequoia (Loopt, Clustrix, Dropbox) before formally investing in YC itself. The institutional bridge was built deal-by-deal before it was formalized. [11]
Finding 3: The Structural Separation of Moritz and McAdoo
The conflict triangle in the Loopt-Green Dot deal was distributed across two Sequoia partners rather than concentrated in one:
If Moritz had directly led the YC investment: Moritz invests in YC → Moritz on Green Dot board → YC company acquired by Green Dot = one person at every node. Visible. Challengeable.
By routing through McAdoo: McAdoo invests in YC (organic — already had Loopt board seat) → Moritz on Green Dot board (separate historical position, pre-dates YC relationship by years) → McAdoo on Loopt board → Loopt acquired by Green Dot = related-party conflict distributed across two partners. Less visible.
Whether this separation was deliberate or emergent cannot be established from available evidence. What can be established: the effect is the same regardless of intent — the conflict was structurally obscured by running through two different partners rather than one. [11][13]
Finding 4: Sequoia as TrialSpark Investor
Sequoia invested in TrialSpark’s seed round (September 2017) alongside Thrive Capital (Josh Kushner). [15] The resTORbio/Project Covalence press release (July 28, 2020) explicitly names “Michael Moritz” as an investor alongside “John Doerr, Thrive Capital, and Sequoia Capital.” [16]
This means: when Altman’s nonprofit (OpenResearch) granted $1M to TrialSpark for Project Covalence (FY2020), the money went to a company in which Sequoia — the same firm whose partner sat on Green Dot’s board during the Loopt face-saving deal — already had equity. The nonprofit-to-commercial pipeline documented in the Project Covalence profile runs through Sequoia’s portfolio from the beginning. [16]
Finding 5: The Green Dot Governance Failure
Harvest Capital Group, an activist investor, filed SEC proxy materials (DFAN14A) that explicitly described Moritz as an “entrenched venture capital holdover director with no industry operating experience” who treated Green Dot as a “personal fiefdom.” Harvest documented that Moritz attended less than 75% of board meetings in 3 of 4 years. During his 13-year tenure, Sequoia distributed approximately $280M of Green Dot stock. [17]
In May 2016, with the proxy fight vote being counted, Moritz and fellow director Timothy Greenleaf resigned from the Green Dot board — hours before they were to stand for re-election. After 13 years, Moritz bailed the night before the vote rather than face shareholders. No explanation was given. [17]
The Green Dot governance failure period (2013-2016) maps precisely to Altman’s board tenure. Green Dot had no notable board governance disruption before 2013 or after 2016.
Finding 6: The FTX Write-Down
In November 2022, Sequoia wrote down its $214M investment in FTX to zero after Sam Bankman-Fried’s crypto exchange imploded. [9] Sequoia had previously published a laudatory profile of SBF in which a partner was quoted asking “Am I talking to the world’s first trillionaire?” SBF was answering partner questions during an investor pitch while playing a video game. [18]
The FTX write-down is not directly connected to the Altman network. It is documented here because it demonstrates Sequoia’s due diligence failures on high-profile investments during the same period the firm was investing in TrialSpark/Formation Bio and participating in the network’s deal flow. The firm that couldn’t detect FTX’s fraud also invested in the company that operated Project Covalence.
Finding 7: The 2023 Global Split and China Exposure
Sequoia’s June 2023 announcement that it would split into three independent entities (completed March 2024) was driven by US-China geopolitical tensions, portfolio conflicts, and regulatory pressure. [5][6][7]
Sequoia China (now HongShan), led by Neil Shen, had invested in major Chinese tech companies including ByteDance, Pinduoduo, and Meituan. The split means Sequoia’s US/Europe operations are now formally separated from its China exposure — but partners’ personal investments across regions were historically permitted, and the institutional relationships built over 18 years of shared operations don’t dissolve with a corporate restructuring.
This intersects with the broader investigation through the YC China / Benchmark China / MiraclePlus thread documented in prior sessions. Sequoia’s China operations, YC China (2018-2019), and Benchmark’s Manus AI investment (via Cayman wrapper) all represent Silicon Valley firms navigating US-China capital restrictions through structural separation.
Finding 8: The Crankstart Foundation and SF Standard
Moritz’s Crankstart Foundation funds the San Francisco Standard, a news outlet that covers San Francisco technology companies — including companies Moritz invests in through Sequoia. Moritz serves as chairman of the SF Standard. [19]
This is documented in the circular dealing analysis as Method I (Media Capture / Feedback Loop Suppression): Moritz funds the media outlet that covers Moritz’s portfolio companies. Whether the SF Standard has ever connected two threads in its reporting on Sequoia portfolio companies is an analytically notable absence if confirmed.
The Sequoia Portfolio Overlap Matrix
Companies where Sequoia and Altman held simultaneous or sequential positions:
| Company | Sequoia Position | Altman Position | Overlap Type |
|---|---|---|---|
| Loopt | Series A investor. McAdoo on board. | CEO and co-founder. | Investor-CEO. McAdoo on seller board during Green Dot acquisition. |
| Green Dot | Moritz on board 2003-2016. ~$280M stock distributed. | EVP 2012-2013. Board member 2013-2016. | Co-board members. Same board during Harvest proxy fight. |
| Y Combinator | $2M institutional investment (2009, McAdoo-led). | Part-time partner 2011. President 2014-2019. | Institutional investor in entity Altman ran. |
| Stripe | Moritz on board (2011-present). | Personal investor ($633M stake, trial exhibit). Altman scouted Stripe for Sequoia. | Altman’s scouting created Moritz’s board seat. |
| Airbnb | McAdoo led seed ($600K). McAdoo on board. | Personal investor (pre-Sequoia). Pointed Thiel to Airbnb. | Personal investment preceded institutional. |
| Instacart | Moritz on board (2013). | Personal investor (Series B/C 2014). | Both invested; McAdoo had departed. |
| TrialSpark/Formation Bio | Seed investor (2017, Moritz named). Series D participant (2024). | OpenResearch $1M grant (FY2020). Series C co-lead ($156M). Personal $19M stake. | Nonprofit grant → company Sequoia already invested in. |
| Boom Supersonic | McAdoo on board (2017). Moritz personal investor. | YC Continuity Fund Series A. Altman on board same day as McAdoo. | Simultaneous board appointments. Dec 2024 down round: both participate. |
Nodes / Open Questions
- Did McAdoo or Moritz formally recuse from any aspect of the Loopt-Green Dot deal? No recusal has been documented in any public filing, press report, or proxy material. Both were in formal governance positions on opposite sides of the same transaction through the same partnership.
- What did YC receive from the Loopt sale? YC invested in Loopt as part of its S05 batch. The amount YC received from the $43.4M acquisition has never been publicly disclosed.
- What was Sequoia’s total return on the Loopt investment? They received ~23.8% of merger consideration. On a $5M Series A (with NEA), the $43.4M exit was modest but face-saving. What were the total invested dollars across all rounds?
- When exactly did Sequoia invest in TrialSpark? The seed round is dated September 2017. Was this before or after Altman’s relationship with TrialSpark/Liu began? Did Sequoia’s investment precede or follow Altman’s involvement?
- Sequoia Heritage — does it hold positions in any Altman portfolio companies? Sequoia Heritage manages partners’ personal wealth. If Heritage holds positions in Altman-network companies beyond what the main funds hold, that’s an additional layer of financial interest.
- The GraffitiGeo acquisition (2009): Loopt acquired YC-backed GraffitiGeo with McAdoo on its board. What were the terms? Was this another network-facilitated transaction?
- What is the full scope of Moritz’s personal investment portfolio vs. Sequoia’s institutional portfolio? The Boom Supersonic investment was personal (not Sequoia institutional). The Getir investment was family office before Sequoia institutional. How many times does the personal-before-institutional layering pattern repeat?
- Did the SF Standard ever report critically on any Sequoia portfolio company? The absence of connective or critical reporting from a Moritz-funded outlet covering Moritz-adjacent companies would itself be a finding.
- What is Sequoia’s current position in Formation Bio? They participated in both seed (2017) and Series D (2024). What is the total dollar exposure? What governance rights do they hold?
- The FTX due diligence failure: Sequoia published a laudatory SBF profile, invested $214M, and wrote it to zero. What was the due diligence process for TrialSpark/Formation Bio? Was it more or less rigorous than FTX?
