Team

Our own capital, alongside every founder.

Esteep Investments is led by two operators turned investors. We deploy our own capital alongside every founder we back, and we hold without a fund clock.

Ryan O'Halloran

Ryan O'Halloran

Co-Founder

Ryan leads capital allocation, founder relationships, and portfolio construction at Esteep Investments. He works closely with the founders we back — the frontier companies the next decade depends on, across aerospace, defense, AI, energy, and critical infrastructure.

Ziad Haddad

Ziad Haddad

Co-Founder

Ziad brings more than two decades of operating experience to the partnership. His operator's eye for execution risk is central to our diligence process — separating companies with real engineering moats from those still discovering their problem.
