"The most transformative companies are the ones that fundamentally change how people think about an important part of their lives," said Amy Errett, Founder and CEO of Madison Reed, and Pendulum board member. "Pendulum is doing exactly that for human health. The company's scientific rigor, groundbreaking work in the microbiome, and commitment to making cutting-edge innovation accessible to consumers are what drew me to the opportunity. I'm excited to join the Board and help Pendulum continue expanding its impact as awareness of the microbiome's role in health continues to grow."

"Amy's decision to join Pendulum reflects the growing importance of the microbiome as a foundational pillar of health," said Hugh Martin, Chairman and Chief Business Officer of Pendulum Therapeutics. "Her expertise in brand building, consumer engagement, and company growth will help accelerate our mission and expand awareness of the transformative potential of microbiome science."

Errett has long been dedicated to philanthropy and public service. She served on the board of GLIDE for more than 21 years and has also served on the boards of the University of Connecticut Foundation and Common Sense Media. She currently serves on the board of Wild Salmon Center.

Backed by more than a decade of rigorous R&D, Pendulum brings a level of credibility unmatched in the field. Its breakthroughs in microbiome science include Pendulum Glucose Control, the first and only probiotic clinically proven to reduce A1C in people with Type 2 diabetes, as published by BMJ (2020). The company also pioneered live Akkermansia muciniphila, a keystone strain that strengthens the gut lining and supports metabolic balance. Today, Pendulum is the #1 Gastroenterologist Recommended Brand of Akkermansia-based probiotics and continues to expand the potential of microbiome science across metabolic, digestive, and whole-body health. The company recently launched Gut Fuel, a first-of-its-kind doctor-formulated fiber mix-in powder designed to nourish the gut microbiome. It combines resistant starches, diverse plant fibers, and polyphenol antioxidants to feed beneficial gut bacteria. Its next-generation flavorless format integrates seamlessly into beverages, snacks, and culinary dishes alike, making it easy to nourish the microbiome without changing how or what people eat.

Pendulum is supported by leading investors including Mayo Clinic, Sequoia Capital, Meritech Capital, True Ventures, and Khosla Ventures.
