About

We build the measurement layer for health.

Fieldflux Biosystems started from a question medicine never formally answered: what does being 'healthy' actually mean? We wrote that definition down — as mathematics a computer can verify — and then built the instruments to read it.

One definition, many instruments — the science, the platform, and the products that read it.

What we believe

Principles we build on.

Definition first

Define it before you measure it

You cannot honestly measure health until you have said, precisely, what it is. The definition comes first; every instrument is downstream of it.

Proven, not inferred

Show the work

Our science is a deterministic analytic surrogate — a defined function of its inputs — not a trained model. Every result can be replayed from the raw record and traced to the mathematics behind it.

Measurement, not diagnosis

Stay in our lane, honestly

We form images, maps, and fields of the body's response. We do not output diagnoses or treatment instructions — by design. Our standards →

The team

Founder-led, and deliberately small.

Fieldflux is a founder-led company with a senior, cross-disciplinary team: formal methods; mathematical, observational, and theoretical physics; signal processing; mobile engineering; and clinical science, all under one roof.

Foundational work rewards depth over headcount. We keep the team small and the standards high, and we bring in partners — clinicians, researchers, and investors — where their judgment sharpens ours. Detailed team and advisor bios are shared with qualified partners as part of our investor materials →
