Olo begins with recordings made in biodiverse natural environments around the world. The sounds of forests, wetlands, water, birds and insects are woven together with original acoustic compositions to create a sense of depth, movement and presence.

You don't just listen to Olo.
You step inside it.

For the moments when you need a shift

When your mind won't stop after a hard call.
When you've been in back-to-back meetings all day.
When you need to come down before you go home.
When you can't sleep the night before a launch.
When you need a clear head for a big decision.
When you feel far away from yourself.
Or when you simply want a little more space.

Olo gives you somewhere to go without going anywhere.

Olo comes with you, and works offline. Use it at home, while travelling, in a hotel room, between meetings, before sleep — whenever you need a moment of your own.

Through the day

07:00 · morningBefore Slack begins.The first hour is for your own clarity and big ideas. Give your thinking room before the operational day takes over.

12:00 · middayBetween calls.Reset between what happened and everything still waiting for you.

15:00 · afternoonInstead of another coffee.The afternoon dip. Step out of the rush for five minutes, then meet the next thing as more yourself.

19:00 · winding downLeave the day where it happened.A small threshold between work and the life waiting on the other side.

22:00 · nightSomewhere softer to land.When the body is tired but the to-do list is still moving. Put on the Olo Eye Mask and let the dark do the rest.

The research

Measured in the body

In a peer-reviewed study co-authored by Olo's founders, ten minutes of a nature-based soundscape improved heart rate variability and slowed heart and breathing rate — signs of the body shifting toward rest.

Participants also reported feeling less anxious, and more comfortable, creative and connected.

You don't need to know how to meditate

There is nothing to get right.
Nothing to achieve.
Just listen.
Notice what happens.

“I attended a live Olo sound journey a little over a month ago. It took me through a trip I haven't experienced and I found so much clarity. Since the event, I have used the app at least once a day.”

Veronica Parado

“I've struggled all my life with meditation… Tonight, I experienced something different with Olo. This was the next level of guidance for my mind and emotions.”

Our story

Olo began with a question we had each been asking in different ways for decades: what helps human beings feel most alive?

Markus Pesonen and Catarina Brazão on the Lisbon waterfront at dusk, the 25 de Abril bridge behind them — Markus Pesonen and Catarina Brazão, Olo’s co-founders

Markus came to it through nature, music, sound, and the way environments shape experience. Catarina came to it through psychosomatic work, nervous-system regulation, and years of helping people recover their relationship with themselves.

We saw that people were trying to change while living inside environments that kept their bodies braced. So we built Olo to change the space first — through sound, darkness, design, human presence, and adaptive intelligence.

We're founders too. We built Olo while fundraising, shipping and travelling, and we use it for the same reasons you will.

The goal is simple: help people feel safe enough to feel again, trust what they know, and return to aliveness.

Frequently asked questions

How do I get my kit?

Your Founder Kit comes through TRMNL4 when you join a cohort or the community. Your 90 days start when you redeem them in the app.

What is Olo?

Olo is a sound experience for nervous-system regulation. Through spatial sound, total darkness, and sensory immersion, Olo helps your body shift state in minutes and build a rhythm of recovery you can return to.

Do I need to know how to meditate?

No. Olo is designed for people who find effort-based practices hard to sustain. You do not need to control your thoughts, follow a technique, or perform the session correctly.

What happens after the 90 days?

Your annual plan begins when the 90 complimentary days end. To stop before then, cancel in your App Store or Google Play subscriptions and you won’t be charged.

Is Olo on Android?

Yes. Olo is available on iPhone and Android.

What do I need?

Just your phone and headphones. Olo works offline too.

Is Olo a replacement for therapy or medical care?

No. Olo is a nervous-system support platform and should not be used as a substitute for professional medical or mental health care. People under clinical care should follow guidance from their provider.
