Flybridge

Quantum exposure limited to one legacy position: Aliro, the Harvard NarangLab spin-out whose 2019 seed Flybridge co-led. Flybridge did not appear in Aliro's most recent rounds (Oct 2023 led by Leaders Fund; Feb 2026 led by Gutbrain Ventures), and its current $100M Flybridge 2025 fund is exclusively AI-focused.

Active Boston, United StatesFounded 2002

Investment thesis

Founded in Boston in 2002 by Jeff Bussgang, Chip Hazard and David Aronoff (Aronoff departed in 2019); now a pre-seed and seed firm with offices in Boston and New York and over $1 billion under management.

Fully AI-focused since January 2024 ('AI as sole focus'); current vehicle is Flybridge 2025, a $100 million seventh seed fund backing AI infrastructure, agentic business applications and native AI applications.

Quantum exposure is a single legacy position: Aliro (Aliro Technologies, Inc.), a 2019 spin-out of Prineha Narang's NarangLab at Harvard, whose $2.7M seed Flybridge co-led with Crosslink Capital and Samsung NEXT.

Strength is the East Coast academic pipeline (Harvard, MIT, Cornell, Columbia) and pre-seed sourcing through its Next Wave network funds, including Next Wave NYC.

Anti-thesis

The patterns that trigger a fast no with this fund.

  1. Flybridge declared AI its 'sole focus' in January 2024; a quantum founder is pitching outside the firm's stated thesis
  2. Its only quantum deal is the 2019 Aliro seed; the firm did not visibly participate in Aliro's October 2023 round (led by Toronto's Leaders Fund) or its February 2026 round (led by Gutbrain Ventures), and Aliro's own site now credits 'Cisco and Accenture' as its lead backers, not Flybridge
  3. David Aronoff, the partner who championed Aliro, left Flybridge at the end of 2019; nobody on the current investment team covers quantum or deep tech hardware
  4. Check size tops out around $3M at seed, thin for capital-intensive quantum hardware; the Opportunities Fund only follows into existing portfolio
  5. Boston quantum founders have specialist alternatives (Quantonation, The Engine, 2048 Ventures et al.) with real reserve capacity for the category
