Hoy lanzamos Rest en español. Como fundador argentino, este lanzamiento tiene un significado muy especial para mí.

English below ↓

Se estima que entre 150 y 200 millones de adultos en América Latina tienen síntomas de insomnio. En Estados Unidos, cerca de 9 millones de adultos hispanos tienen dificultades para dormirse o mantenerse dormidos la mayoría de los días.

Para millones de personas, recibir ayuda en español es una condición básica para poder mejorar su sueño.

Por eso adaptamos el programa de Rest al español, trabajando con especialistas en sueño hispanohablantes.

El costo tampoco debería ser una barrera. Todo nuestro contenido educativo es gratuito, junto con el diario de sueño, el cálculo de una ventana de sueño personalizada y herramientas de relajación.

La versión Premium suma un coach de IA que va aprendiendo sobre vos y te acompaña con educación personalizada y coaching diario. En nuestro estudio publicado, quienes completaron ocho semanas con el coach de IA de Rest redujeron, en promedio, a la mitad el tiempo que tardaban en dormirse y el que pasaban despiertos durante la noche.

Elegimos esta semana para lanzar Rest en español porque este sábado es el Día Mundial de la Salud Mental. Una revisión de 65 estudios encontró que mejorar el sueño también mejoraba la salud mental, reduciendo los síntomas de depresión y ansiedad. Más personas merecen acceder a ese apoyo.

Today, we’re launching Rest in Spanish. As an Argentine founder, this one feels especially meaningful.

An estimated 150–200 million adults across Latin America experience insomnia symptoms. In the US, roughly 9 million Hispanic adults struggle to fall or stay asleep most days.

For millions of people, getting support in Spanish is essential to improving their sleep.

That’s why we adapted Rest’s sleep program into Spanish, working with Spanish-speaking sleep experts.

Cost shouldn’t stand in the way either. All our educational content is free, alongside a sleep diary, a personalized sleep window and relaxation tools.

Premium adds an AI coach that learns about you and guides you through personalized education and daily coaching. In our published real-world study, users who completed eight weeks with Rest’s AI coach cut their time to fall asleep and time awake at night roughly in half, on average.

We chose this week to launch Rest in Spanish because World Mental Health Day is this Saturday. A review of 65 randomized trials found that improving sleep also improved mental health, reducing symptoms of depression and anxiety. More people deserve access to that support.

Know someone who could use this? Please pass it along!

@demibrener Congrats!!!

[Martin Siniawski @msinia]

Today we're publishing real-world results from Rest, the world's first AI sleep program.

After eight weeks with Rest, users on average cut the time it takes to fall asleep and the time spent awake at night roughly in half (52% and 49%, real-world cohort of 318 users).

Rest matches what behavioral sleep programs led by human coaches and clinicians achieve, at a fraction of the cost, with no waitlist, and available 24/7.

This will be a game changer for the 70 million Americans with insomnia symptoms and no good alternatives.

With all the understandable concern about AI, this is one example of it being used for good.

Very proud of our team, including the incredible sleep experts who helped us build Rest. This is a big milestone for all of us.

Thank you @langfuse for this write-up on how we build Rest, our voice AI sleep coach.

Langfuse has been part of our stack since we found it through the YC network, and the team has been a pleasure to work with: responsive, high standards, always shipping.

Proud of our team. Full story below.

Late night podcast usage made the Rest team realize that 70M Americans suffer from symptoms of insomnia.

That's why they built Rest. A sleep coach built on the principles of CBT-I. Learn how they use Langfuse to cut the coach's memory issues in half.

Last night Rest showed up where insomnia actually lives: TikTok Shop at 3am.

This Sleep Awareness Week, we didn't want to talk about sleep during the day. We wanted to find people at the exact moment insomnia has them in its grip — scrolling, making bad decisions ("late night mistakes"), doing anything but sleeping.

Streamers went live teasing sleep "hacks" — cooling pillows, melatonin gummies, panda-eye concealers. All of it a setup to offer something actually backed by science that works: Rest.

In one night, we partnered with creators reaching a combined audience of over 500,000 people. People who were wide awake when they wanted to be sleeping. We met them in their worst moment and offered them a real way out — an AI-powered sleep program built on real clinical science, not another band-aid.

Because this Sleep Awareness Week there's no shortage of awareness that sleep matters. What's missing is awareness that effective solutions actually exist.

If you or someone you know is struggling with sleep, this Sleep Awareness Week we're offering 50% off: https://t.co/JgKLBrYrTi

Live TV before coffee hits different ☕

Grateful to have joined Annie Miller, MSW, LCSW-C, LICSW and @MaureenUmehFox5 on FOX 5 DC this morning for Sleep Awareness Week.

For years the advice has been: "just put the phone down." But anyone who's stared at the ceiling at 2am knows it's not that simple. You don't scroll because you want to. You scroll because sleep won't come and you don't know what else to do.

That's exactly why we built Rest, to prevent those nights from happening in the first place and give people the capacity to show up for their lives.

Not a sleep sound. Not a gummy. A program that actually retrains your brain to sleep.

Incredibly proud of what the team has built, and even more excited about what's coming next. If you've ever lost a night to the scroll, this is for you.

Full analysis: https://t.co/VVJ8ZaIlhM

[Martin Siniawski @msinia]

We analyzed over 1,000 messages from a viral sleep thread. What we found changed how I think about online sleep advice.

A fitness coach offered $1,000 to anyone who could fix his 10-year insomnia. The post exploded—6,000+ replies, 1.7 million views. Even Matt Walker and Bryan Johnson jumped in.

I clicked through expecting maybe some good advice. What we found was... fascinating.

We decided to analyze it. Over 1,000 messages. Every recommendation categorized, counted, cross-referenced.

I thought we'd find consensus. Maybe a few standout solutions everyone agreed on.

Instead, we found chaos.

52 different interventions with enough traction to matter. Everyone absolutely certain their answer was THE solution.

The #1 recommendation? A supplement—but not the one you'd expect. Even within those mentions, people contradicted each other on which type, how much, and when to take it.

Then the sleep advice got weird:
- Skydiving
- Sleeping on boats
- Eating blocks of cheese before bed
- Shining lights in... unexpected places

All impossible to distinguish from the legitimate medical advice.

What's someone supposed to do with all this?

If you wanted to test things methodically—just 2 weeks per intervention—you'd need 2 years.

But sleep is complex. Many respondents didn't recommend just one thing—they shared specific combinations, sequences, and protocols.

Want to try combinations of 2 interventions? 51 years.

This isn't an outlier. It’s what happens when someone asks for sleep advice online.

When you're awake at 3am, desperate for answers, 1,000 conflicting suggestions aren't helpful—they're paralyzing.

Here's what shocked me most:

The treatment with an 80% success rate, recommended as first-line therapy by the American College of Physicians and American Academy of Sleep Medicine?

3 mentions.

Three.

We broke down all the data: which interventions people swear by, the exact contradictions, the outlandish recommendations, and why the treatment that actually works barely got mentioned.

P.S. Have you ever asked for sleep advice online? Was it helpful or did it just make things worse? I'd love to hear what happened.

[Martin Siniawski @msinia]

Amazing to see so many people sharing what worked for their sleep.

We dove into the data from 1,000+ responses to look for patterns.

Thought the community might find the breakdown interesting: https://t.co/HGCLQDs6eX

[Martin Siniawski @msinia]

Hey Nik — I feel you, that's incredibly frustrating. If you want to understand what's happening and the non-pharma approach that actually works (80% success rate), check out Dr. Ashley Mason's breakdown on Peter Attia's podcast: https://t.co/AhLsQNdCny

She's a UCSF sleep researcher focused on CBT-I (the first-line treatment for insomnia). We built Rest with her to make that protocol accessible and easy to follow with AI. If you want to get started now rather than DIY it, happy to give you access:

Hey Ty — totally get how brutal that can be. I run Rest (https://t.co/P6SRHUY3W8), an AI-based sleep protocol built with Dr. Ashley Mason (UCSF) — she was on Peter Attia’s podcast earlier this year.
It’s helped thousands reduce time awake at night, number of awakenings, and time to fall asleep. Happy to give you free access if you’d like to try it.
