01 · Market formation
From science to markets
The strongest opportunities emerge where breakthrough science meets strategic demand, regulatory change and a credible pathway to adoption.
Frontier technology investing
Investing where breakthrough science meets institutional readiness.
Founder & Managing General Partner of R3i, I invest in and build frontier-technology companies with proprietary science, defensible intellectual property and credible pathways to institutional adoption — across AI, deep tech, health, climate and critical minerals, operating across Europe, Asia-Pacific, Australia and North America.
The investment thesis
Frontier technology becomes durable when capital, governance and execution align.
02 · Institutional readiness
Governability creates value
Defensible intellectual property, trusted data, regulatory readiness, procurement discipline and operating resilience determine whether technical advantage can withstand institutional scrutiny.
03 · Strategic capital
Capital with intelligence
Frontier companies need more than financing. They need clarity on what to prove, which risks to retire, where to partner and when to move.
04 · Structural defensibility
Beyond the application layer
As AI becomes increasingly accessible, we underwrite what remains scarce: proprietary science, patents and protected intellectual property, validated evidence, regulated workflows, manufacturing capability and strategic distribution.

In their words
What founders and co-investors say.
“Leesa works exceptionally hard to support founders and connect the right people. I have worked with several tier-one venture-capital partners, and Leesa's impact is above anyone I have had the pleasure of working with. She is a model of what a founder should want in an investor.”
“The energy, knowledge and connections Leesa brought to our deep-tech company were invaluable. She combines commercial judgement, a deep understanding of the global investment landscape and an exceptional willingness to help, while fostering ambition, cooperation and confidence across the team.”
