  • Jacob Kimmel - Pioneering a predictive biology revolution to reverse aging
    Jan 13 2026

    Dr. Jacob Kimmel is the President of NewLimit, a biotechnology company developing reprogramming medicines to treat age-related disease and extend human healthspan. Dr. Kimmel co-founded the company with Blake Byers and Bryan Armstrong, and has since raised over $300M from top venture capital funds like Kleiner Perkins, Dimension, Founders Fund, and Khosla Ventures. They expect to initiate their first clinical trial in a few years.


    Dr. Kimmel has garnered a reputation as one of the brightest minds in longevity and the intersection between artificial intelligence and molecular biology, and NewLimit is often cited as one of the most important companies building in longevity today.

  • Reprogramming the cell from aged to healthy with siRNA - Dr. Janine & Rob (Junevity)
    Dec 9 2025

    Dr. Janine Sengstack and Rob Cahill, founders of the startup Junevity, are on a mission to extend lifespan and healthspan by combining AI and large scale omics data with genetic medicines known as “siRNAs”. Their cellular reset platform promises to create medicines that can reset each of your organs back to a healthy and youthful state.This year, Junevity successfully restored "18-year-old metabolism" in animal models allowing mice on a high-fat diet to lose fat while retaining muscle. This candidate therapy may become the first known drug to rejuvenate metabolism. Since our recording, Junevity doubled their seed round funding up to $20M to advance this work into human clinical trials, which means we might see their first rejuvenating medicine in the clinic as soon as the second half of next year.
