Jonathan Chauvette — Helping health and longevity companies grow

Background

Operator first. Advisor second.

I've spent most of my adult life building businesses, not advising them from the sidelines.

I've built teams, carried risk, made payroll, negotiated hard deals, and worked through the years where nothing goes to plan.

That's the perspective I bring: an owner's mindset. I've sat in the chair founders sit in, with my own money on the line.

Health and longevity has been a personal focus for the past ten years. Putting twenty years of building behind the founders working in it is what comes next.

2005 — 2019
Built an industrial group

Co-founded a machinery group alongside my father and grew it to roughly 125 employees and $15M in revenue. Sales, marketing, business development.
2020 — 2025
Founded, scaled and sold Starlight

A North American equipment distributor I founded in 2020, started with an exit in mind, and sold to new owners in December 2025.
Today
Health and longevity

Working alongside a small number of health and longevity companies as an advisor and growth partner, while building Beyond 100.

Who I work with

Founder-led companies with a strong product and a growth challenge.

I work primarily with founder-led health and longevity companies: small, growing teams with traction, funding or an established business, where senior entrepreneurial and commercial experience can support the next stage of growth.

Scale revenue

You have traction and want to grow faster. We find the biggest commercial opportunities and focus the team on the levers that actually move revenue.

Profitability and cash flow

Revenue is there, but too little of it reaches the bottom line. We work through pricing, margins, product mix and the cash cycle to find what's quietly eating your profit.

Product-market fit

Your product works, but is it in front of the right customers? We review the fit, the positioning and the channels, and where complementary offers could open new demand.

Rethink the bigger picture

Where the business goes next, what to build, what to stop, whether to raise capital or one day sell. We step back, challenge the assumptions, and decide what actually matters.

Working together

Three ways to work together.

We work at the level of involvement the business actually needs. I take on a small number of companies at a time, and there are no hours to count.

Growth Diagnostic

A focused engagement to understand what's holding the business back and where the highest-value opportunities are.

Time with your customers, not just your team
Every recommendation with a number attached
Three decisions to make, not twenty pages to read

If you get to the end and don't think it was worth the fee, you don't pay it. Fixed fee, agreed before we start.

Strategic Advisor

Ongoing access to an entrepreneur who knows your business, challenges your thinking, and helps you decide what to do next.

Recurring strategy sessions
Access between the meetings
A second read on the calls that matter

A monthly rhythm. Cancel anytime, no long contract.

Growth Partner

Deeper involvement, inside the business alongside you and your team, where I help you execute, not just decide.

Commercial strategy, from plan to execution
Key negotiations, partnerships and hires
In the room where decisions happen

One company at a time. Retainer, with equity when the fit is strong.

Not sure which one fits? Most conversations start without knowing.

The Growth Diagnostic

What actually happens.

No black box. Here's how it goes, from the first conversation to the plan in your hands. If you already know you want an advisor, we can start there instead.

01 / TALK

A free first conversation

We talk about the business, where you want to take it, and what's in the way. No cost, no commitment. If I'm not the right person, I'll say so.

02 / GATHER

Getting the full picture

Financials, sales numbers, and a short questionnaire on your strategy, your market and your biggest roadblocks.

03 / DIG IN

We dig in

Analysis, follow-up questions, conversations with your team, and time on the ground when it helps. This is where the real answers show up.

04 / DELIVER

You get the plan

Findings, priorities and a roadmap, walked through together. From there it's your call: run with it, or keep me on month to month.

Beyond 100

Documenting the journey.

I'm exploring what it actually takes to live a longer, healthier, more active life: through conversations with specialists and researchers, and by experimenting on myself and publishing what I find.

My goal is to ski at 95 and live well beyond 100.

The conversations

A first run of interviews with specialists, researchers and athletes in health and longevity. Paused while I sold my company. New conversations start this fall.
