About Us

GRObio has a distinguished scientific and business team – world-renowned pioneers with decades-long careers dedicated to genome engineering, computational biology, and therapeutic development

  • Our science emerged from some of the most distinguished labs in the world. Our founders developed our platform technologies in the labs of George Church at Harvard Medical School and Andrew Ellington at University of Texas, Austin, pioneers of synthetic biology.
  • We are supported by top-tier investors that have a proven track record of success in developing biotechnology platforms, commercializing novel therapies, and driving exponential growth in value. Our business team has closed over $2B in transactions.
  • We have highly engaged, world-class advisors for specific disease indications that have led commercialization of blockbuster drugs, and have held top-level positions in academia and industry. Our Commercialization Advisory Board has decades of experience in drug discovery, clinical development and partnership transactions.
  • Our core values are courage, learning, openness, and humility, and we believe we’re building something revolutionary with near limitless possibilities to improve health outcomes for patients. Check out our career openings.

Our Approach

We aim to identify and solve holy grail problems in medicine. We search for unmet clinical needs that our platform can uniquely address. From autoimmune conditions to metabolic diseases, we’re only scratching the surface of possibilities to improve the lives of patients.

We’re striving to fulfill the promise of protein-based therapies by reprogramming biology. Our GRO platform creates novel proteins with an expanded alphabet of non-standard amino acids (NSAAs), providing therapeutic modalities that were previously impossible. Our production process is scalable, stable, and sustainable.

GRObio’s mission is to leverage the unprecedented capabilities of NSAAs in our GRO platform to overcome longstanding limitations in protein therapeutics and bring better health outcomes to patients. Our Biofoundry pairs computational protein design with sophisticated robotics, bringing sea-change acceleration to the development of NSAA therapeutics.

We’re applying our groundbreaking science to advance partnered and collaborative programs, as well as our own pipeline of unique NSAA therapeutics with the promise of unprecedented potency, stability, and immunotolerance.
