Hangzhou Just Biotherapeutics is an integrated design company focused on technologies that will accelerate development of biotherapeutics and substantially reduce their manufacturing cost. Our core strengths are molecular design, process and product design and manufacturing plant design.

We believe scientific and technological innovation will catalyze expansion into new cost-sensitive markets, creating new therapeutic approaches with biologics like antibodies. Our initial product focus will leverage integrated design approach, where our technology can make the greatest impact.

Working with selected partners and collaborators, we will deliver lasting value by creating access to important biologics in a global marketplace.

Heal the World

Hangzhou Just Biotherapeutics (HJB) was founded in 2016 by an experienced team spanning the fields of protein, process and manufacturing sciences to help complete a mission that began in the early 1980’s. This mission has been to solve the scientific and technical hurdles blocking access to life changing protein therapeutics. Enormous progress has been made over the last 30 years in biotechnology, with the discovery and development of new and effective protein therapeutics across the spectrum of human disease. The cost of making these complex therapeutics has also decreased substantially, but unfortunately not enough, to make current and future protein therapeutics accessible to a growing global population. Completing the mission will require an intense focus on the development of innovative and integrated technologies, from the design of therapeutic molecules to the design of the plants used for manufacturing them. This is why HJB was founded.

We decided to name the company Just because the word suggests a sense of fairness and equality. A minority of our world is enjoying a literal medical revolution as the understanding of biology enables the discovery and development of life changing therapeutics. At HJB, our passion and mission is to help bring this medical revolution to the entire world.

In supporting and believing in our mission, thank you to our current investors.
