The science
Understanding begins with better questions.
We believe understanding a baby deserves as much attention as helping them settle. Sleep is our starting point, and evidence is how we decide what we can responsibly claim.
01 · Understanding before intervention
Not every awakening is fussiness.
Newborns move through different sleep and waking states. Movement can happen during sleep, and an awake baby can be calm and alert rather than distressed.
Crying can also be a late hunger cue. Feeding, comfort, a normal sleep transition or something in the environment can all matter. A sound or movement tells us that something happened; it does not, by itself, explain why.
Korrah is being built toward bringing parents more context, rather than treating quietness as the only measure of success.

02 · Caregiving continues through the night
Caregiving doesn’t stop at bedtime.
Human studies of bedtime and nighttime parenting have found associations between emotionally available, responsive care and patterns in infant cortisol. These studies are observational: they do not prove that one specific nighttime behavior causes a particular developmental outcome.
They do support a principle we care about deeply: the caregiver remains part of the nighttime environment. Technology should support parents’ observations and decisions, not replace them.
Quietness alone cannot tell us why a baby settled, what they needed, or whether independent regulation occurred.

Notice the baby, not just the noise.
Waking, movement and crying are different observations. Context helps a caregiver decide what matters.
Keep human judgment central.
Parents bring knowledge no single sensor has: routines, feeds, comfort and what is normal for their child.
Technology should make care clearer.
The goal is not constant intervention. It is better information when a parent needs it.
03 · Sleep and development
There is more to sleep than duration.
Infant sleep changes rapidly across the first year. Developing sleep includes active or REM sleep and quiet or non-REM sleep, with patterns that mature over time.
Human infant EEG research has shown that sleep-related twitches become coordinated with sleep spindles as infants develop. In separate animal research, REM sleep was shown to participate in pruning and maintaining newly formed synaptic connections in the developing mouse motor cortex.
These studies motivate the questions we ask. They do not show that Korrah improves brain development, and they do not make total sleep time a complete measure of development.

04 · Context makes observations more useful
A signal is not an explanation.
What was measured: a change in room temperature, sound, movement or physiology is an observation.
What the parent knows: feeding, routine, comfort, illness concerns and what is normal for that child add context a sensor does not have on its own.
What an interpretation might suggest: patterns can help raise better questions, but a room-temperature reading, for example, does not establish why a baby woke.
This is the direction behind Insight and ELLA: keep measurements, caregiver input and interpretation distinct, and show uncertainty rather than turn a signal into a conclusion.

05 · The foundational intelligence layer
The most formative years are still the least continuously understood.
In adult health, continuous personal data is increasingly familiar. Early development is still often encountered in fragments: a visit, a caregiver observation, a short study window or a single night.
Our thesis is that the first years deserve a deeper longitudinal record. By bringing sleep, physiology, environment and caregiver context together over time, Korrah is being built to make patterns visible that no single signal can show.
We do not yet know every connection that will matter. That is part of the opportunity: some patterns may help families ask better questions, while others may become questions for researchers to investigate.
Today
Early life arrives in snapshots.
Appointments, caregiver memory, isolated measurements and short observation windows can each tell us something. They rarely tell the whole story over time.
What Korrah is building
Longitudinal developmental context.
Sleep, physiology, environment and caregiver context brought together across nights, weeks and, eventually, stages of development.
What may become possible
Better questions from connected patterns.
Patterns can support new hypotheses for families and research. They do not establish causation, diagnosis or developmental outcomes on their own.
Korrah is building the foundational intelligence layer for early human development. Not because we already know every answer, but because we believe the earliest years deserve the depth of longitudinal understanding increasingly expected elsewhere in health.
06 · Product-specific evidence
Research informs us. Testing must prove our products.
Published research can shape what we build and which questions we ask. It cannot substitute for testing Embrace, Insight or ELLA themselves.
We are building toward product-specific validation of sensing accuracy, sleep-state interpretation and how well ELLA separates observations from inference. Developmental claims require their own evidence before we make them.
Korrah is not intended to diagnose, treat or prevent any condition, including SIDS, or to replace safe-sleep practices, caregiver supervision or monitoring prescribed by a clinician.

Published research
What informs our work.
The studies above help explain why infant sleep, caregiver context and interpretation matter. They were not trials of Embrace, Insight or ELLA.
Product-specific validation
What our products must earn.
We will test sensing against appropriate reference methods, evaluate interpretation quality and uncertainty, and validate any sleep-stage or developmental claim before making it.
Coming 2027
What we are building.
Embrace, Insight and ELLA launch together. Readings and conversations shown on this site are illustrative until product-specific validation is complete.
We will publish methods, results and limitations as validation is completed. Researchers and clinicians can contact us about collaboration.
