Building, backing, and scaling the next generation of deep technology companies.
We back founders in biotech, AI/ML, and robotics — supported by operators who have built cell-therapy platforms, shipped advanced hardware, and governed enterprise risk for two decades.
AI / ML
Applied intelligence in scientific discovery, healthcare, and industry — models that touch the physical world, not just the browser.
Robotics & Automation
Advanced materials, sensing, and machines that make labs, factories, and care delivery more capable.
Biotech & Healthcare
Cell and gene therapy, regenerative medicine, and the platforms that industrialize them — where our operating history runs deepest.
Founders who possess...
Technical advantage
Proprietary methods or insight competitors can't easily replicate.
Defensible IP
Patents, trade secrets, or regulatory moats that hold up over time.
Scientific insight
An understanding of the underlying science, not just the application.
Exceptional execution
A track record of shipping, not just researching.
Global ambition
Building for a market beyond the first customer.
Small checks, serious diligence, zero friction.
First checks
We invest early, alongside the syndicates and funds you already want on your cap table.
Operator diligence
Technical review by people who have run process development, materials labs, and enterprise controls.
No board seats
Quiet, supportive capital. We help when asked and stay out of the way when not.
Built to last
A multi-generational family firm — we measure outcomes in decades, not fund cycles.
