The endocrine layer of sleep

Clarity,
delivered nightly.

We're building Lyra, a small oral wearable to unlock the endocrine layer of sleep. Because everybody deserves a good night's sleep.

01 / Sleep health, for everybody

Your sleep deserves
a closer look.

Sleep is shaped by more than how long we spend in bed. Hormones follow patterns across the night, adding another dimension to how we understand rest.

We're developing sensors that use target-specific aptamers to measure hormones in saliva. Our goal is to help researchers and clinicians study the endocrine layer of sleep, with repeated measurements that fit into the night.

MelatoninCortisol
Relative trends, scaled independently
Illustrative melatonin and cortisol patterns during a night In this example, melatonin rises to a broad overnight peak and starts falling toward morning. Cortisol pulses throughout the night at roughly 90-minute intervals, with lower overall levels early and a rise toward morning. Actual pulse timing varies. Each hormone is scaled independently. These are stylized trends, not measured concentrations or Cicada results.

One moment gives you two values. Repeated measurements reveal how the patterns change.

For better nights, everywhere

Let's ask better
questions about sleep.

Work in sleep health, circadian science, or hormone research? We'd like to understand the questions you're asking and the measurements you need.
