SCOTTSDALE, Ariz., Sept. 24, 2026 — Jetstream Venture Fund (Jetstream), an innovative interval fund dedicated to opening access to institutional-grade deal flow for a wider mainstream audience, today announced a strategic investment in Rejuvenation Technologies. The biotechnology company is pioneering targeted mRNA therapies designed to extend telomeres, aiming to restore cellular regenerative capacity and treat severe age-related diseases.
This addition solidifies Jetstream’s position at the forefront of longevity science, life extension, and advanced gene therapy. Rejuvenation Technologies joins recent Jetstream portfolio additions Rejuvenate Bio (a Harvard-spun gene therapy company backed by Merck Animal Health), and Wonderlab Bio, a pioneer in off-the-shelf cell therapies. Together, these investments create a cohesive, high-growth portfolio, granting everyday retail investors access to the future of human healthspan and cellular repair.
Born out of foundational research at Stanford University by CEO and co-inventor Dr. John Ramunas, Rejuvenation Technologies utilizes modified mRNA delivered via proprietary lipid nanoparticles to specific organs. Unlike permanent telomerase activation, this transient approach temporarily extends telomeres to reverse years of cellular aging in a single day.
Backed by top-tier institutional investors, including Khosla Ventures and Y Combinator, and supported by over $8 million in non-dilutive grants from the NIH and CIRM, the company is rapidly advancing preclinical pipelines targeting idiopathic pulmonary fibrosis and severe chronic liver disease.
“Rejuvenation Technologies represents the kind of highly technical, paradigm-shifting science Jetstream seeks to identify early,” said Chris Yoo, Fund Manager at Jetstream. “By adding their breakthrough mRNA platform alongside our existing stakes in Rejuvenate Bio and Wonderlab Bio, we are thrilled to offer our investors a seat at the table for disruptive technologies that could fundamentally alter how we treat chronic, age-related diseases.”
By securing early-stage access to companies addressing massive gaps in regenerative medicine, Jetstream continues to break down the barriers of venture capital to everyday investors.
