'What if we could give every child's brain the deep sleep it was designed to have?'
40% increase in deep sleep duration through acoustic stimulation

HelianWell began in 2021 when our founders - a pediatric neuroscience researcher and a hardware engineer who had just become parents - found themselves in the same situation as millions of families: staring at the ceiling at 3am, wondering why their baby couldn't stay asleep.
They tried everything. White noise machines, sleep training programs, expensive consultants. Some things helped temporarily. Nothing addressed the core issue: their child's brain wasn't spending enough time in deep sleep - the phase where real neural development happens.
So they went back to the research. Not parenting blogs. Not influencer advice. The actual peer-reviewed neuroscience. And what they found changed everything.
In 2019, researchers at the University of Zurich published a landmark study demonstrating that precisely calibrated low-frequency sound stimulation could increase time spent in deep sleep by up to 40%. The mechanism - auditory neural entrainment - works because the brain naturally synchronizes its electrical oscillations with external rhythmic patterns.
A follow-up study from Northwestern University confirmed these findings: targeted acoustic stimulation during sleep enhanced slow-wave activity by 25-40%, with measurable improvements in next-day cognitive performance. Participants who benefited most were those with the lowest baseline deep sleep - exactly the population that needed help the most.
Research from the University of Tübingen added another dimension: enhanced slow-wave sleep through acoustic stimulation directly increased growth hormone secretion - the hormone responsible for physical growth, neural myelination, and immune system development in children.
The science was clear. What was missing was a device that could bring it into a family's home.

Born et al., Nature Neuroscience, 2018Every child deserves the deep, restorative sleep their brain was designed to have. Not just 'sleeping through the night' for exhausted parents - real, deep, delta-wave sleep. The kind that builds neural pathways, releases growth hormones, consolidates memory, and gives every child the cognitive foundation they will draw from for life.
We built HelianWell because the science is clear and the technology exists. The only thing missing was a bridge between the research lab and your nursery.
