The titanium ring that reads your body 24/7 — and plans, fuels and adapts your training
HELIOS tracks 80+ biomarkers around the clock — then the THRIVE app turns every night's recovery into tomorrow's plan: training, fuelling and readiness. 7–10 day battery. No straps. No more guesswork.
Your body's been telling you how to train for years. You just couldn't read it. HELIOS reads every signal 24/7 — and THRIVE turns it into one clear plan, so nothing gets missed and no ride is wasted.
How it Works
ONE RING. ONE APP.
Your entire cycling stack, on one finger.
Bike computer, power meter, smart watch, sleep tracker, nutrition app and coach, replaced by a ring you forget you're wearing.
DATA CONTINUITY
Every rider loses weeks without knowing it.
You go hard on a day your body wasn't ready for, or roll out under-fuelled for the long one, and the week quietly goes nowhere. THRIVE runs sleep, training and nutrition as one dataset, so those days stop happening and your goals get closer, faster.
RIDE FOR DECADES
Add years to your riding life.
Overtraining and under-recovery end cycling journeys quietly, and sometimes even lives. A recovery routine built off nutrition, sleep and your personal training plan is the answer to a long, strong life on the bike.

See the full picture of your riding
THRIVE watches the numbers that shape your season — recovery, load, sleep, fuelling — and shows how today's choices change tomorrow's ride.
Be informed so you catch a bad day before it costs you.
HRV, resting HR, skin temperature, sleep — your full picture, tracked continuously, so warning signs never go unnoticed.
Daily updated so you know exactly what your body can handle today, tailored for your training plan
Daily readiness reads strain, recovery and sleep — so you stop guessing and start training.
An elite bike computer for every ride. Nothing extra needed on the bars.
Full ride mode in the THRIVE app — live metrics, maps, turn-by-turn voice nav. The phone is the ride computer.
Sleep tracking and recovery insights with cycling in mind.
Ring-grade sleep staging — not a wrist guess — so you know exactly how well your body rebuilt overnight.
Track, plan and execute climbs, with power metrics.
Climbing Mode shows climb power and the profile ahead — so you pace the climb instead of surviving it.
Every effort (cycling, strength, mobility), tracked every second.
Heart rate, zones, distance, calories — captured automatically, 24/7. Everything in one place.
Fuelling that connect the cycling dots. Track and manage your nutrition every way possible.
Training, fuelling, recovery, sleep — one closed system. Because the numbers only make sense together.
Tell Marco what you ate. He logs it. Nutrition tracking has never been easier.
Say it, type it or scan it — Marco logs the meal to your diary, updates today's targets and keeps the fuelling plan honest.
A coach with capability and context of your training, recover and nutrition.
Marco reads your recovery, plan and fuelling before every call, shows the steps he took, then proposes — you approve. Grounded in your data, not made up.

Wake up knowing exactly what to do today
Most riders only find out they're cooked when the session falls apart — when the damage is already done.
HELIOS reads recovery, sleep and strain around the clock — and flags the morning your body isn't ready, before you waste a key session.

"THRIVE flagged a rough night and proposed an easier Tuesday. The week still built — and I was fresh for the weekend race."
— Tom R., masters racer
Your fitness is built between rides — sleep, recovery and load decide whether a block makes you faster or buries you.
THRIVE reconciles plan vs reality every day — it flags what changed and proposes the rebuild. You approve it in a tap.
Every day starts with one readiness number: exactly what kind of day your body's ready for.

"I stopped negotiating with my training plan. It flags, it proposes, I approve — and the season keeps building."

Wake up knowing exactly what to do today
Readiness reads how well your body rebuilt overnight — sleep staging, HRV, resting HR — and turns it into today's call.
Push day or easy day — the plan, the fuelling targets and the session all line up with how you actually recovered.
Fuel follows the training: hard days more, rest days less — off your real body.

Your Daily Readiness
Coaching That Plans Your Season — Not Just Scores It
Other wearables score yesterday's workout.
THRIVE is a full training system — plan, fuel, ride and recover in one place, built for cyclists.
A recovery score is a label.
Readiness with a plan behind it is a system.
THRIVE says: “Readiness 82 — you're fresh. Today's intervals hold, and your fuelling plan is loaded: 75 g of carbs an hour on the bike.”
Others say: “You're 82% recovered.”
We don't just score your morning. We turn it into today's plan — and you approve it.
One Subscription
One Plan Covers Everything — $8.99 a Month
THRIVE: $8.99/mo after a free first month — Marco, plans, fuelling, everything.
Others: a training app + a nutrition app + a recovery app — $30+/mo, stacked.
One ring, one app, one subscription. Cancel anytime — the plan, the fuelling and Marco are all inside it.
Built For Cyclists
Real Ride Intelligence — Not Just HRV
THRIVE: Climbing Mode, a live ride screen, EST power trend, structured training mode.
Others: great sleep scores. The ride itself was never their job.
THRIVE closes the loop — the ride feeds recovery, recovery reshapes the plan, the plan fuels the ride.
Know Your Body
A Plan — Not Just A Score
Others hand you scores built from HRV, sleep and heart rate.
THRIVE turns them into decisions — daily.
The ring reads your body 24/7; the app reconciles plan vs reality every morning — training, fuelling and recovery in one call.
Scores are interesting.
Decisions win races.

“Finally broke through my plateau!”
HELIOS Smart Ring
I was stuck at the same FTP for 8 months. HELIOS showed me I was overtraining and needed more recovery. Within 6 weeks of following the AI coach, I gained 15 watts and finally dropped the guys who used to drop me.
Marcus, 34 years old Boulder, USA
“Like having a pro coach on my finger”
HELIOS Smart Ring
Between work and family, I only get 6 hours a week to train. HELIOS tells me exactly what workout to do each day based on my recovery. No more wasted rides. Every session counts now.
Sarah, 38 years old Sydney, AUS
“The data changed everything”
HELIOS Smart Ring
I used to second-guess every training decision. HELIOS gives me confidence that I'm doing the right thing every single day. My trends caught overtraining before it became an injury. Game-changer.
Jake, 31 years old Austin, USA
“No more chest strap chafe”
HELIOS Smart Ring
Sensitive skin made every long ride miserable with a strap. HELIOS reads within a couple bpm of my old strap on intervals, and I forget it is even there. Wish I had switched a year ago.
Priya, 29 years old Bangalore, IND
“Got me through a 600 km brevet”
HELIOS Smart Ring
Marco kept me from blowing up at the wrong moment three different times across 28 hours of riding. The fueling reminders alone earned back the subscription. I rode sharper than ever.
Henrik, 41 years old Copenhagen, DK
“8% better power-to-weight in 90 days”
HELIOS Smart Ring
I followed the plan Marco built for the full 90 days and set PRs on three different climbs. The plan adapted every week based on what the ring saw. No marketing claim — just my own data.

Putting it simply
After a hard block your nervous system stays in fight-or-flight longer, so HRV dips while your body prioritises repair. It’s normal — and it’s the cue to ease off. Two easy days and it rebounds above baseline.

HEART-RATE MONITORING
Push with confidence. Know your heart, every mile.
HELIOS reads your heart rate continuously — and Marco flags the moment it runs too high or too low, so you know when to push and when to back off.
Live · Zone 4 · Threshold
148bpm
EA-based nutrition
Fuel the work, not the guesswork.
Marco turns every session into a precise fuelling plan — exact carbs, fluid and timing, before, on the bike and after. No apps to wrangle, no maths.
01 · Today's prescription
Eat for the ride ahead
Exact carbs before, on the bike and after — plus the protein to rebuild. Built around today's session, not a generic number.
02 · Daily fuel target
Hit the number that matters
Your kcal and carb targets adapt to every ride and rest day — so you never under-fuel a big day or overeat an easy one. Low energy availability flagged early.
03 · A plan that adapts
Moves with your week
Rest days run on your baseline; training days add the session's burn, fuelled 1:1. Change the plan and every target updates with it.

01The night
While you sleep, HELIOS keeps working.
Every 30 seconds, the ring logs your sleep stages, heart rate and temperature — building the most accurate recovery picture you’ve ever had.
02The read
It reads the signals your body sends overnight.
The five markers sports scientists trust to measure true recovery — captured while you do nothing but rest.
03The verdict
You wake up knowing how hard to ride.
Marco turns the whole night into one number — your readiness — and a clear plan for the day ahead.
04Body clock
And it learns your natural rhythm.
Over weeks, HELIOS maps your circadian rhythm and chronotype — so it knows the hours you’ll ride strongest, and when your body wants to wind down.

A NOTE FROM THE FOUNDERS
Why we built HELIOS
W
e started THRIVE because we were tired of riding with a watch, a chest strap, a cycling computer, a recovery app, a sleep tracker and a coach we never had time to call back. Three of us are cyclists. One of us is a sports physiologist. All of us were drowning in data that lived on six different screens.
HELIOS started with a question: what if the sensor disappeared, and the coaching showed up where you actually live — on your phone, in your morning, on your ride? Eighteen months later, this is what we shipped. A 2.4-gram titanium ring that catches every signal a chest strap catches. A platform that turns those signals into one number you can act on. And a team of coaches and sports scientists sitting behind the AI so it never feels like talking to a robot.
We can't promise HELIOS will turn you into a Cat 1 racer. We can promise it will give you back the brain cycles you spent juggling devices, and replace them with a clearer answer to one question: how do I ride better tomorrow than I did today. That's all we set out to do.
This is launch pricing for the HELIOS ring. You're not just buying a ring — you're joining the first group of riders shaping what we build next.

Rider stories
From the community
“Finally broke through my plateau!”
HELIOS Smart Ring
I was stuck at the same FTP for 8 months. HELIOS showed me I was overtraining and needed more recovery. Within 6 weeks of following the AI coach, I gained 15 watts and finally dropped the guys who used to drop me.
Marcus, 34 years oldBoulder, USA
“Like having a pro coach on my finger”
HELIOS Smart Ring
Between work and family, I only get 6 hours a week to train. HELIOS tells me exactly what workout to do each day based on my recovery. No more wasted rides. Every session counts now.
Sarah, 38 years oldSydney, AUS
“The data changed everything”
HELIOS Smart Ring
I used to second-guess every training decision. HELIOS gives me confidence that I’m doing the right thing every single day. My trends caught overtraining before it became an injury. Game-changer.
Jake, 31 years oldAustin, USA
“No more chest strap chafe”
HELIOS Smart Ring
Sensitive skin made every long ride miserable with a strap. HELIOS reads within a couple bpm of my old Polar on intervals, and I forget it is even there. Wish I had switched a year ago.
Priya, 29 years oldBangalore, IND
“Got me through a 600 km brevet”
HELIOS Smart Ring
Marco kept me from blowing up at the wrong moment three different times across 28 hours of riding. The fueling reminders alone earned back the subscription. I rode sharper than ever.
Henrik, 41 years oldCopenhagen, DK
“8% better power-to-weight in 90 days”
HELIOS Smart Ring
I followed the plan Marco built for the full 90 days and set PRs on three different climbs. The plan adapted every week based on what the ring saw. No marketing claim — just my own data.

Putting it simply
After a hard block your nervous system stays in fight-or-flight longer, so HRV dips while your body prioritises repair. It’s normal — and it’s the cue to ease off. Two easy days and it rebounds above baseline.

Training Calendar
Push with confidence. Know your heart, every mile.
HELIOS reads your heart rate continuously — and Marco flags the moment it runs too high or too low.
Live · Zone 4 · Threshold
148bpm
EA-based nutrition
Fuel the work, not the guesswork.
Marco turns every session into a precise fuelling plan — exact carbs, fluid and timing, before, on the bike and after. No apps to wrangle, no maths.
01 · Today's prescription
Eat for the ride ahead
Exact carbs before, on the bike and after — plus the protein to rebuild. Built around today's session, not a generic number.
02 · Daily fuel target
Hit the number that matters
Your kcal and carb targets adapt to every ride and rest day — so you never under-fuel a big day or overeat an easy one. Low energy availability flagged early.
03 · A plan that adapts
Moves with your week
Rest days run on your baseline; training days add the session's burn, fuelled 1:1. Change the plan and every target updates with it.
Validated accuracy. In a 3–4 g shell.

Replaced my chest strap and my readiness app
HR tracking is within 2bpm of my old chest strap in every ride — including a 4hr threshold day. Best thing I’ve bought for cycling this year.

Feels like a coach who actually sleeps
Cancelled two other subscriptions. Sleep tracking is more useful than my old ring because Marco actually says something with it.

Brilliant, but pairing took two attempts
Hardware is excellent. Knocking a star because pairing took two attempts. App could also use a way to silence Marco for a day.

It called my overreach a week before I felt it
Marco flagged three days of suppressed HRV and recommended two days easy. I ignored him, did the threshold workout, blew up. Now I listen.

Hardware great, subscription stings a bit
The product itself is 5 stars. Knocking it down because the monthly locks the features I bought it for. Should be clearer upfront.

Finally — no more chest strap chafe
Sensitive skin made a chest strap hell on long rides. This replaces it and reads within 1–3bpm of my old strap on intervals.

A note from the founders
Why we built HELIOS
We started THRIVE because we were tired of riding with a watch, a chest strap, a cycling computer, a recovery app, a sleep tracker and a coach we never had time to call back.
HELIOS started with one question: what if the sensor disappeared, and the coaching showed up where you actually live — on your phone, in your morning, on your ride?
We can't promise HELIOS will turn you into a Cat 1 racer. We can promise it will give you back the brain cycles you spent juggling devices.

A NOTE FROM THE FOUNDERS
Why we built HELIOS
W
e started THRIVE because we were tired of riding with a watch, a chest strap, a cycling computer, a recovery app, a sleep tracker and a coach we never had time to call back. Three of us are cyclists. One of us is a sports physiologist. All of us were drowning in data that lived on six different screens.
HELIOS started with a question: what if the sensor disappeared, and the coaching showed up where you actually live — on your phone, in your morning, on your ride? Eighteen months later, this is what we shipped. A 2.4-gram titanium ring that catches every signal a chest strap catches. A platform that turns those signals into one number you can act on. And a team of coaches and sports scientists sitting behind the AI so it never feels like talking to a robot.
We can't promise HELIOS will turn you into a Cat 1 racer. We can promise it will give you back the brain cycles you spent juggling devices, and replace them with a clearer answer to one question: how do I ride better tomorrow than I did today. That's all we set out to do.
This is launch pricing for the HELIOS ring. You're not just buying a ring — you're joining the first group of riders shaping what we build next.
