About
A growth practice built on AI agents.
Free Saint is a solo-led, agent-powered growth agency for health and wellness brands. One senior operator. A stack of ChatGPT agents. Zero six-figure specialists between you and your growth number.
Founder
Chako Arai.
Speaker · Investor · Longevity strategist · AI agent architect
Chako Arai is a growth marketer, real estate investor, and entrepreneur on a mission to help women over 35 divide their age by two. She is the founder of Free Saint, creator of the Free Saint Longevity Ecosystem, and author of the book Divide By Two.
She has spent a decade+ inside the health and wellness category — telehealth, supplements, Shopify DTC, med spa, fertility, mental health, and clean beauty — leading growth for brands that treat regulated wellness as their moat.
At Free Saint she architects ChatGPT agent stacks that replace what used to require a full team — a paid buyer, an SEO lead, a CRO analyst, a copywriter, a Shopify dev, a lifecycle manager — and supervises the whole system personally. The result: a practice that ships faster than any traditional agency, proves every result in a dashboard, and costs a fraction of what a specialist-heavy retainer runs.
The Book · Divide By Two
A cinematic longevity system for women over 35.
Divide By Two is Chako Arai's science-backed protocol for reversing biological age through gut health and central nervous system health — the two systems that quietly govern hormones, energy, skin, sleep, mood, and metabolism.
A 15-chapter roadmap covering the 12 biological failures that accelerate aging and the exact strategies that reverse them. Backed by science. Powered by data. Driven by a mission to help one million women over 35 become biologically younger, more vibrant, and fully alive again.
- Heal the gut–brain axis
- Regulate the central nervous system
- Balance hormones & boost energy
- Rebuild skin, hair & metabolism
- Optimize sleep, fasting & mitochondria
- Measure & lower your biological age
Aging isn't inevitable. It's programmable.
Principles
How we work.
Data or it didn't happen
Every strategy is instrumented before it ships. Dashboards, not decks. Attribution, not vibes.
Agents over specialists
Orchestrated ChatGPT agents run the tactical work of a full growth team — at a fraction of the salary load.
Wellness first, always
We only work with brands in health, wellness, telehealth, aesthetics, mental health, and clean beauty.
One senior operator, accountable
No junior staffing pyramid. Chako runs every engagement personally, supervising the agent stack end to end.
