Ely Tsern

Co-Founder & Chief Innovation Officer Bryte

Last Reviewed: September 19, 2026

Executive Summary

Ely Tsern is a co-founder of Bryte and its Chief Innovation Officer, responsible for the technology inside the Bryte Balance — a smart bed built around ninety near-silent medical-grade air coils that sense a sleeper’s pressure points and inflate or deflate in real time to remove them before they cause a wake-up. He came to the bedding industry from an unlikely direction. He holds a Stanford doctorate in electrical engineering, earned in 1996 for work on error-resilient video compression, and spent much of the following two decades at the memory-technology company Rambus, where he is named as an inventor on a substantial body of patents. He moved into sleep after the death of his eight-year-old son from leukaemia led him to look for work with a more direct human effect. Bryte, which he co-founded in 2016 with John Tompane and Jonathan Farringdon, shipped its first bed in 2019 and is now on its third generation of hardware, sold direct and through luxury hotel partners.

Career Highlights

• Co-founded Bryte in 2016 with John Tompane and Jonathan Farringdon, and is listed as both an executive officer and a director on the company’s Regulation D filings in 2021 and again in 2024.
• Named Chief Innovation Officer of Bryte, one of three executives on the company’s current leadership team alongside chief executive Luke Kelly and chief technology officer Mark Handel.
• Earned a Stanford electrical-engineering PhD in June 1996 under Teresa H. Meng, for a dissertation on error-resilient video compression for portable applications using pyramid vector quantization.
• Worked at Rambus, the memory interface and IP licensing company, where his supervisor’s Stanford page recorded him as Engineering Director and where he is named as inventor on patents including memory refresh logic that accommodates low-retention storage rows.
• Brought Bryte’s first product to market in 2019 and has since taken it through three generations, adding BryteWaves, a feature that synchronises gentle head-to-toe motion in the mattress with curated audio.
• Solved the noise problem before shipping: he has said the near-silent air pumps driving the Balancer coils were a prerequisite for entering a market where competing air systems used audible machinery.

Professional Journey

Tsern’s first career was in silicon. He finished a Stanford PhD in electrical engineering in June 1996, working under Teresa Meng on compressing video robustly enough to survive the error rates of portable wireless links, and went from there to Rambus in Los Altos, the company whose memory interface technology sat between processors and DRAM across much of the consumer electronics industry. He rose through engineering leadership there, and his name appears on a long sequence of Rambus patents covering memory controller and DRAM techniques. Aggregator records place him as a vice president in its memory products group and its chief technologist for memory and interfaces until 2016; the company itself has not published a confirmation of those titles.

The turn came from outside work entirely. His son was diagnosed with leukaemia and, after years of treatment, died at the age of eight. Tsern has described the effect plainly: a career spent on computers and large servers stopped feeling sufficient, and he began looking for something that would make a difference to people. He was not going to cure cancer, he has said, but when a friend approached him about bringing technology and sleep together he took it seriously, met sleep researchers at Stanford and UC Berkeley, and was introduced to Matthew Walker, who ran the Center for Human Sleep Studies at Berkeley.

The insight that founded Bryte in 2016 was that sleep is dynamic while a mattress is static. Working with Walker, the team set out to build a platform rather than a better foam. The result was a bed containing ninety air coils — Balancers — and sensors that track pressure across the body, with a small computer in the foot of the bed managing the experience, cloud-connected and driven by an app that lets each sleeper set firmness and contour independently on their own side. The first product launched in 2019. Bryte raised on the strength of it: a Form D filed in January 2021 records an offering of roughly $24.5 million, of which about $17.5 million had been sold.

Tsern held operating roles through that period — aggregator records give him the chief operating officer’s seat from 2016 and the chief executive’s from 2020 to 2022 — before settling into the innovation remit he holds now, with Luke Kelly as chief executive. The corporate vehicle changed along the way: a second company, Bryte Labs, Inc., was incorporated in 2024 and filed its own Form D that August, with Tsern, Kelly and Brian Walsh named as its related persons, and it is Bryte Labs that the current terms of sale identify as the operator of the business. The product itself is doing well in the market it entered: Bryte’s beds took a run of 2026 awards including USA Today’s best smart mattress, and the company continues to sell direct and through hotel partners.
