“This isn't just one gene edit—this is multiple edits, working in concert. It’s a fundamentally different chassis.”

In this episode of The Biotech Startups Podcast, Aaron Edwards, co-founder of KiraGen Bio, shares how a Harvard Business School class project ignited the launch of a pioneering biotech taking on solid tumors with a bold, unconventional CAR T-cell therapy.

He unpacks the real-world challenges of building KiraGen—navigating fundraising, assembling a strong team, and leveraging mentorship, partnerships, and machine learning—while highlighting how focus, discipline, and authentic leadership can set a startup apart, even when it means breaking from industry norms.

Key topics covered:

  • The Origin of KiraGen: Born from an HBS pitch deck, KiraGen set out to tackle immune suppression in solid tumors.
  • Contrarian CAR T-Cell Design: Bold multi-edit strategy to outsmart tumor microenvironments and hit glioblastoma.
  • Focus and Discipline: Lean operations, every dollar counts, eyes on clinical milestones.
  • Creative Fundraising and Partnerships: Unconventional funding, academic alliances, and patient-driven capital.
  • Authenticity and Team Building: Realness, inclusivity, and mentorship at the core—paying it forward in biotech.
