About
Kas Bordier
I'm an entrepreneur working on a simple idea most people overlook.
Your health is shaped long before willpower gets involved.
The spaces we live in quietly train our nervous system every day. Light, air, sound, materials and temperature act as constant signals. Most of them go unnoticed. All of them matter.
When these signals are misaligned, people feel tired, wired, restless or foggy and assume the problem is them. It usually isn't.
My work focuses on making these invisible influences visible, measurable and deliberately designed so homes support human vitality instead of quietly draining it.
I don't believe better health starts with more discipline.
I believe it starts with better environments. That's what I build.

MAVI Longevity
Co-founder of MAVI, the longevity layer to real estate. MAVI designs homes where longevity isn't something you do, it's something that happens to you. Through air that doesn't inflame, light that doesn't confuse, materials that don't poison, and rhythms that don't fight you. We call it interior biology.

Environment as the first health layer
Most approaches to health focus on behavior: what you eat, how you exercise, when you sleep. These matter, but they're downstream of something more fundamental: your environment.
The environment you live in shapes your biology before willpower ever enters the equation. A bedroom with the wrong light spectrum will disrupt your circadian rhythm regardless of your sleep hygiene. Poor air quality will impair your cognition no matter how focused you try to be.
You can't out-supplement a building working against you. That's why I focus on the invisible layer first.
Background
A path shaped by curiosity
I didn't arrive here through theory or career planning.
I arrived because health wasn't there when I needed it.
That experience made me pay attention to what most people overlook. Light. Air. Sound. Materials. Temperature. The quiet forces that shape how we feel, think and function at home.
Over time, this became my work. Applying these principles to real homes and real buildings with developers and private clients.
MAVI grew out of that process. Through MAVI and MAVI & Friends, I work with designers, practitioners and scientists focused on one thing: environments that support human vitality.
I live this work. If it doesn't work in real life, it doesn't belong here.
Principles
Guiding values
Biology over trends
Design decisions are guided by how the human body actually works, not by what's fashionable.
Precision and softness
Rigorous thinking doesn't mean cold spaces. The goal is homes that feel warm and alive.
Compounding benefits
Small environmental improvements create cascading effects on health over time.
Lived systems
Homes should evolve with the people inside them. Design is never finished.
The best time to plant a tree was twenty years ago
The second best time is now. Your future self will thank your present self for starting this conversation. Most people wait until something breaks before they fix it. The clever ones fix the environment first.
I'm genuinely curious about what you're building, where you live, and what matters to you. No pitch, no pressure. Just a conversation about possibility.
