Saro Passaro

Saro Passaro is an Italian mathematician (IMO 2018 silver, 2019 bronze) and machine-learning researcher. He studied Mathematics at the University of Cambridge and is a co-founder of Boltz, an MIT Jameel Clinic spinout public benefit corporation applying open-source AI to biomolecular modeling and drug discovery. Boltz launched with a $28M seed round and a Pfizer partnership in January 2026. His research spans equivariant graph neural networks and the Boltz model family (Boltz-1, Boltz-2, BoltzGen). His public/aggregator career record also lists research roles at MIT, Meta (AI Resident), a stealth AI startup, and a 2021 quantitative-researcher stint at G-Research.

• Boltz launched with a USD 28M seed round and a Pfizer partnership, announced 8 Jan 2026 from the MIT Jameel Clinic spinout; Saro named as one of three founders.Jan 8, 2026
• Quant employment verification: UNRESOLVED. The only candidate quantitative-finance role is 'Quantative Researcher at G-Research' (Jun-Sep 2021 per the provided lead), which appears in two aggregator/index sources (RocketReach and the LinkedIn enrichment index) with no independent primary-source confirmation found in this run (no G-Research page, press item, or the subject's own published statement naming the role). Employer classification: G-Research IS a quantitative research/technology firm, so the employer passes; the specific role and dates remain index-only and unconfirmed. Identity is corroborated (IMO Italy 2018/2019, Cambridge Mathematics, Boltz co-founder all align), so the ambiguity is about the role evidence, not the person. Retaining uncertainty explicitly.
• Co-founder of Boltz (boltz.bio), a public benefit corporation for AI biomolecular modeling; Boltz's models (Boltz-1, Boltz-2, BoltzGen) are open-source. Co-founders named: Gabriele Corso, Jeremy Wohlwend.Jan 8, 2026
• Journalist-facing aggregator RocketReach lists dated roles: Co-Founder @ Boltz 2025-now; AI Research Scientist @ MIT 2024-2025; AI Researcher @ Stealth AI Startup 2023-2024; AI Resident @ Meta 2022-2023; Quantitative Researcher @ G-Research 2021. Aggregator-sourced, NOT primary-source confirmation.
• LinkedIn-derived career history (index-only, not primary-source confirmed) lists the same roles in reverse order plus Machine Learning Researcher at University of Cambridge with InVivo AI.
• Boltz employer classification: Boltz is an AI drug-discovery / biomolecular-modeling company (public benefit corporation). It is NOT a quantitative-finance, trading, market-making, hedge-fund or systematic-trading firm.Jan 8, 2026
• G-Research employer classification (for the one quant-finance candidate role): G-Research is a UK quantitative research and technology business; its own site and vacancies describe quant research/technology roles. Classification as quantitative finance employer is supported, though the specific role remains index-only.Jan 1, 2026
