A life sciences-specialist investment firm that invested in both 23andMe (genetic data source) AND TrialSpark (clinical trial platform) — both sides of the 23andMe-TrialSpark clinical trial recruitment partnership — while its founder ran SPACs that mirror the Altman network’s AltC structure.
Bio
Casdin Capital is a New York-based investment firm founded in 2011 by Eli Casdin, specializing in life sciences, healthcare, biotechnology, genomics, and synthetic biology. The firm manages a portfolio of 154+ companies and has been active in both private venture rounds and public market positions for over a decade. Casdin’s investment thesis centers on “the incredible knowledge base unlocked by the accelerating capability to read and manipulate molecular information.” [1][2][3]
Eli Casdin earned his B.S. from Columbia University and MBA from Columbia Business School. Before founding Casdin Capital, he served as Vice President at Alliance Bernstein’s thematic investment arm, where he authored the 2011 black book “The Dawn of Molecular Medicine” — detailing the wave of innovations in molecular medicine and investment opportunities from testing to targeted medicine, diagnostics to industrial agriculture. Earlier experience includes Bear Stearns and Cooper Hill Partners (a healthcare-focused investment firm). [3][4][5]
Casdin serves on the boards of Exact Sciences (Nasdaq: EXAS), GeneDx, the New York Genome Center, and Columbia University School of General Studies Board of Visitors. He has previously served on boards at Invitae, Relay Therapeutics, Magenta Therapeutics, SomaLogic, and 2seventy bio. [3][4][5]
Notable investments include 23andMe, Adaptive Biotechnologies, Recursion Pharmaceuticals, Ginkgo Bioworks, and TrialSpark. [1][2]

TrialSpark Investment
Casdin Capital participated in TrialSpark’s $156 million Series C (September 30, 2021) — the round co-led by Sam Altman and Lachy Groom. [6]
Casdin is NOT listed in the Series D investor roster. The firm appears to have been a one-round participant.
The 23andMe-TrialSpark Dual Position
This is the analytically significant finding for this profile. Casdin Capital invested in both:
- 23andMe — the consumer genomics company with a database of millions of genetically profiled, consented research participants [1]
- TrialSpark — the clinical trial platform that partnered with 23andMe for genetic-data-driven patient recruitment (announced September 26, 2019) [6][7]
Casdin had financial interest on BOTH sides of the 23andMe-TrialSpark clinical trial recruitment partnership. When 23andMe’s genetic data was used to identify patients for TrialSpark’s trial sites, Casdin benefited from both the data source (23andMe) and the data consumer (TrialSpark). This is the same dual-exposure pattern documented for Doerr (TrialSpark + potentially OpenAI), Lin (TrialSpark + potentially OpenAI), and Zaki/Thrive (TrialSpark + OpenAI).
The SPAC Pattern
Eli Casdin was CEO and co-founder of CM Life Sciences (CMLS) — a special purpose acquisition company (SPAC) that took Sema4 public. [8] The SPAC model — creating a blank check company to take a private company public — mirrors the AltC Acquisition Corp pattern (Altman’s SPAC that took Oklo public).
| SPAC | Founder | Target | Outcome |
|---|---|---|---|
| AltC Acquisition Corp | Sam Altman / Michael Klein | Oklo (nuclear) | Merged May 2024. Altman chairman → stepdown Apr 2025. |
| CM Life Sciences | Eli Casdin / Keith Meister | Sema4 (genomic data) | Merged. Sema4 became public genomic/clinical data platform. |
Both SPACs operate in the same structural space: using blank check vehicles to take private healthcare/science companies public while the SPAC founders maintain governance influence.
Network Connections
| Connection | Nature | Significance |
|---|---|---|
| 23andMe | Casdin portfolio company | Data SOURCE for TrialSpark recruitment partnership |
| TrialSpark | Series C investor (Sep 2021) | Data CONSUMER of 23andMe partnership. Casdin on both sides. |
| Sema4 / CM Life Sciences | Casdin CEO of SPAC | Genomic data platform. Same SPAC model as Altman’s AltC. |
| Exact Sciences | Casdin board member | Diagnostic testing company. Broader healthcare governance. |
| New York Genome Center | Casdin board member | Genomics research institution. Academic network. |
| GeneDx | Casdin board member | Genetic testing company. Further genomics exposure. |
| Ginkgo Bioworks | Casdin portfolio company | Synthetic biology. AI + biology intersection. |
| Recursion Pharmaceuticals | Casdin portfolio company | AI-driven drug discovery — same space as Formation Bio’s Muse platform with OpenAI. |
Investigative Findings
Finding 1: Both Sides of the Genetic Recruitment Pipeline
Casdin’s positions in both 23andMe and TrialSpark mean the firm had financial interest on both sides of the data flow: 23andMe’s genetic database → TrialSpark’s clinical trial sites. [1][6][7] When the partnership was announced (September 2019), both companies were in Casdin’s portfolio. When TrialSpark received Altman’s $1M OpenResearch grant (FY2020) and operated Project Covalence, Casdin was invested in the company that controlled the genetic recruitment pipeline feeding into it.
Finding 2: The SPAC Parallel
Casdin’s SPAC (CM Life Sciences / Sema4) and Altman’s SPAC (AltC / Oklo) represent the same governance pattern: private company → SPAC wrapper → public market → founder/SPAC CEO retains governance influence. [8] Both operators come from the same network ecosystem and both target science/technology companies that benefit from public market access while maintaining concentrated insider control.
Finding 3: The Molecular Medicine Thesis
Casdin’s 2011 black book “The Dawn of Molecular Medicine” articulated the investment thesis that genomic and molecular data would transform healthcare — from diagnostics to therapeutics. [3][4] TrialSpark/Formation Bio’s evolution from clinical trial platform to AI-native pharma company represents the execution of this thesis. Casdin invested in the company that is building what his 2011 book predicted: technology-driven drug development powered by molecular data and AI.
Finding 4: Recursion Parallel
Casdin’s portfolio includes Recursion Pharmaceuticals, an AI-driven drug discovery company. [1] Formation Bio is ALSO an AI-driven drug development company (through the Muse platform with OpenAI). Casdin has positions in two companies pursuing AI-accelerated pharmaceutical development — one through drug discovery (Recursion) and one through clinical trial acceleration (Formation Bio). Whether these portfolio companies compete, complement, or share any operational infrastructure is an open question.
Nodes / Open Questions
- When did Casdin invest in 23andMe relative to the TrialSpark investment? If the 23andMe position preceded the TrialSpark Series C, Casdin may have had inside knowledge of the 23andMe-TrialSpark partnership’s outcomes before investing in TrialSpark.
- Did Casdin exit TrialSpark at the Series D? Not listed in the June 2024 round. Did it sell, hold, or roll into the renamed Formation Bio position?
- Sema4 and Formation Bio — any overlap? Sema4 is a genomic and clinical data platform. Formation Bio uses AI for drug development. Both collect and analyze health data. Are there shared data partners, clinical trial sites, or institutional connections?
- Casdin’s “Dawn of Molecular Medicine” thesis and Formation Bio’s trajectory: Did Casdin’s investment thesis specifically anticipate the clinical-trial-platform-to-drug-company evolution? If so, was the Series C investment a thesis-driven conviction bet or a network-allocation?
- Keith Meister (CM Life Sciences co-founder): Meister is an activist investor with a track record of “creating value and effecting change at companies.” What is his relationship, if any, to the Altman network?
