About Pendulum
Pendulum® is leading a revolution that is occurring around the world to improve physical and mental health by first understanding, then restoring and enhancing the human microbiome.
Studies have shown that our microbiome (the bacterial communities in and on our bodies) is linked to everything from metabolism and diabetes, to longevity, weight loss, healthy immune systems, cancer prevention, feelings of well-being, inflammatory bowel disease, and even healthy skin. We have just scratched the surface on understanding the impact that our microbiome has on our lives. During early life we develop a diverse and balanced microbiome that plays a critical role in shaping our long-term health. Over our lives, a combination of diet, lifestyle, antibiotics, and aging can decrease the effectiveness of our microbiome.
Pendulum recognized the enormous impact they could have on people’s lives if they were able to address the imbalances in the microbiome. To accomplish this, Pendulum created proprietary probiotic pipelines and a unique discovery platform to identify key, novel bacterial strains and the prebiotics that feed them. The company has also built and developed the world’s first manufacturing technology to produce bacteria in an anaerobic (oxygen-free) environment at scale.
The medical probiotics that Pendulum has formulated have transformed the consumer probiotics market into a new category of therapeutic offerings that deliver the power and efficacy of a pharmaceutical with the safety and accessibility of a natural probiotic. Due to Pendulum’s explosive revenue and customer growth over the last two years, the company earned a spot on Forbes Magazine’s exclusive “The Next Billion Dollar Startups” list.
If you’re interested in improving the lives of people globally and you love working in a cross-functional, collaborative, inspiring environment, please continue reading.
