THE FOUNDER

Dr. Tara Youngblood

Sleep Scientist. Physicist. Serial Entrepreneur.

"I've spent 20 years studying one question: what does the human body actually need to recover during sleep? The answer isn't a gadget. It isn't an app. It's the surface you sleep on."
"I love sleep trackers, I wear one every night. But a speedometer doesn't make the car go faster. I built the engine."

THE JOURNEY

From Physics Lab to Sleep Revolution

2005-2015

The Research Years

Tara began her career as a physicist, studying thermodynamics and material science. Her personal battle with insomnia led her to apply her scientific training to sleep, specifically the relationship between temperature, pressure, and human recovery cycles.

2016

Chili Sleep Is Born

Tara co-founded Chili Sleep (later Sleepme), creating the first consumer sleep temperature regulation system. The company grew to over 500,000 customers and became a household name in the biohacking community. Dave Asprey, Ben Greenfield, and Dr. Andrew Huberman all became advocates.

2018-2022

The Realization

After years of helping people regulate their sleep temperature, Tara noticed a pattern: even with perfect temperature control, people on poor mattresses still had suboptimal sleep. The surface itself, the pressure it exerts on the body was the missing variable that nobody was addressing.

2023

Geli Is Born

Tara developed a patented gel bead technology that delivers 49% more pressure relief than any consumer mattress ever tested by XSensor. The technology was so effective that XSensor technicians had to recalibrate their equipment, the pressure readings were lower than anything they'd seen.

2025

The Essentia Partnership

Recognizing that the ultimate sleep surface would combine organic purity with pressure science, Tara partnered with Essentia the world's only certified organic performance mattress brand. The Geli Organic by Essentia represents the fusion of two decades of innovation.

2026

Foundation First

Today, Geli is leading a paradigm shift in sleep performance. The message is simple: every great sleep stack starts with a great mattress. Trackers, gadgets, and supplements are valuable additions but they're optimizing a broken system without the right foundation.

THE VISION

"I want every person who cares about their health to understand one thing: your sleep stack starts with your mattress."

Tara's mission isn't to replace your tracker or your supplements. It's to give them a foundation that actually works. When the surface is right, everything else in your sleep stack performs better.
