Built by people who had
too much to lose.
First Person was born from a personal reckoning — and a refusal to accept what we were told was inevitable. What started as a search for answers became a mission to engineer cognitive performance from the ground up.
A family history that made this personal.
Brothers Chris and Joe Claussen watched their grandfather — a sharp, entrepreneurial mind — slowly disappear to Alzheimer's disease. Then their father followed the same path.
When genetic testing confirmed they both carried ApoE4, the strongest known risk factor gene for Alzheimer's, the question stopped being abstract. It became urgent. Personal. Theirs to answer.
They spent years immersed in the science of cognitive health and brain performance — not looking for comfort, but for interventions they could act on, starting today.
Together with entrepreneur and co-founder Cory Rosenberg, they set out to build a company around that conviction — one designed to make cognitive performance accessible, effortless, and part of everyday life.
"Cognitive performance, like physical fitness, is built by the decisions you make every day. It is both a lifestyle choice and a lifelong pursuit."Chris & Joe Claussen — Co-Founders, First Person
Cognitive performance is the target.
Everything else serves that.
Brain health is the foundation — but it has never been the finish line. First Person is built around one question: what can we engineer to help people think, focus, and perform at a higher level, right now and over time?
Immediate performance
Every product delivers a perceptible cognitive lift — sharper focus, faster mental activation, more intentional energy — from the first use.
Long-term protection
The same ingredients that sharpen performance today build the neurological resilience that matters a decade from now. We engineer for both simultaneously.
No compromise on experience
A product that works on paper but fails in daily life is not a solution. If it does not fit the ritual, it does not get made.
This is just the beginning.
First Person began with targeted cognitive supplements and has since expanded into proprietary ingredient innovation and functional coffee. These are the first chapters. The science we have developed — and what it makes possible — goes much further than what you see today.
Cognitive Supplements
Our supplements target specific neurotransmitters — dopamine, serotonin, GABA, acetylcholine — to support focus, motivation, mood, and mental clarity. This is where First Person started, and it remains the scientific core of everything we do.
