For athletes and entrepreneurs · Grounded in science

The edge
nobody sees.

Recover faster and perform when it counts. Private 1:1 work, grounded in science, with a small number of athletes and founders. Confidential by default.

Both free. The check takes 3 minutes, the call 20.

Sound familiar?

You’ve done the work. Race day doesn’t show it.

Early mornings, long weekends, 10 to 15 hours of training on top of a full working week. The numbers in training look great. Then, when it counts, your legs go flat, your stomach turns, or your head won’t switch off the night before. And on Monday, the meetings are waiting.

Doing everything rightand still not getting ahead

Somewhere between training and race day, your performance gets lost. That’s your blind spot, and it’s where we come in.

For cyclists

Your legs on the last climb.

Watts, intervals, kilometres: you track all of it. What decides the last climb never shows up on your head unit: how fast you recover between hard days, how you sleep before the big ride, whether your stomach holds up in hour five. For cyclists heading into a gran fondo, a multi-day event or a big training block, who want their legs when the road tilts up. Pros have people for this. You have your head unit.

For athletes

For entrepreneurs

From the start line to the boardroom.

Your body can't tell race day from a board meeting. It pays for both from the same account. Clear decisions under pressure, switching off in the evening, energy for the whole week: it all comes from the same system. For founders and CEOs who train hard and carry a lot. Racing and running a company? Then both paths are yours.

How we work

Everything starts on the inside.

Training, coach, equipment, nutrition plan: almost everyone invests in the outside. What happens inside you decides whether any of it shows up: how you recover, how you sleep, how you handle pressure. How it all fits together is your blind spot. That's where we start, and it's what your plan is built on. Every step rests on peer-reviewed research, and we'll show you the studies whenever you ask.

The Regulated Athlete · 1:1

Every pro has a team. Who's on yours?

Nobody would start a race without a team. In business, most people try exactly that.

A coach for your training. A physio for your body. Maybe a nutritionist. Each one sees their part, and nobody sees how the parts affect each other. That's the blind spot. We work with you on it for up to twelve months, grounded in sport science, until your system carries everything you've built.

New · Your wearable, if you like

Your trends, on your own device.

Already wear a WHOOP, an Oura ring, a Garmin or another wearable? If you like, you can follow on your own device how your sleep, HRV and resting heart rate develop while we work together. And if you want to, you can note how you feel in a few seconds a day.

Sleepduration and regularity, as your device shows them
HRVyour values over the weeks
Resting heart ratehow it changes over time

The trend says more than any single night. The numbers serve you, never the other way round.

We look at trends together and make no medical diagnoses. No wearable? Everything works without one too.

What it takes

<1 %

of your week. That's all it takes.

You already put 10 to 15 hours a week into training and 50 or more into your company. Working with us takes less than 1 % of your time: under 15 minutes a day. Sessions, check-ins and quick tools that fit into your day, without extra training hours.

We know time is the most valuable currency you have. It's ours too. That's why we only work on the biggest levers. If you want something to change, less than 1 % of your time is a fair deal. The rest of your week is where you feel it, in training, at work and at home.

We're convinced it's the best return on time in your week.

What people tell us

“My workload was just as heavy as before. But I carried it in a completely different way.”

Age-group triathlete and CEO, 44

“I had optimised everything, and along the way I forgot how to relax. I finally understood how deep recovery can go when it comes from the inside. An absolute game changer for me.”

Cyclist, 39, highly ambitious

“My ambition often got in my own way. Now I know exactly what I can influence, and I'm far more successful, even though I need less time than before.”

Manager and triathlete, 46

Who we are

Two champions who hit the wall.

When you work with us, you work with both of us. Jonas, former rowing world champion with a master's in strategy. Ines, European Universities rowing champion and sports scientist. We both lost what we had built, right at the top. And we both found our way back. For you, that means two people who spot early what most people only notice once their body slams on the brakes.

Who we are is why we win.

Where the boat meets the boardroom

Will it make the boat go faster?

For years, Jonas asked himself that question before every decision: the extra session, the late night, the next meal. Today we ask it about your life. Your boat is your season, your company, your family, and every lever we work on has to pass that one test.

An eight only flies when all eight pull together. That's an ecosystem, and we've been building them all our lives: Ines since 1997, Jonas since 2004. First in boats, then in teams and companies. Jonas wrote his master's thesis on ecosystems, Ines coached the U19 national rowing team and managed budgets worth millions. Today we bring both worlds together, for people who live in both.

Where does your community lose performance?

Talks, workshops and a live group analysis for everyone in the room. Everyone scans a QR code, gets their own signal, and the room sees where the group loses performance. For clubs, races, training camps and companies.

Discretion

Your edge stays yours.

We never name the people we work with, and nobody hears about it from us. No logos, no names, no posts about you. What you share with us stays between you, Jonas and Ines.
