Axial - Berkeley #1
Analysis of exciting Berkeley life sciences inventors and their inventions
Inventors have always had the opportunity to create unique business models. Going to school in Berkeley and living a few blocks from campus, there is a storehouse of talented inventors in Berkeley. The ultimate goal is to form companies that otherwise wouldn’t have gotten started for a variety of reasons, access to capital, perspective, and belief with the purpose to create unique business models and make inventions more accessible. The core thesis is to use inventions to create unique business models for founder-driven life sciences companies; ultimately, it’s easier to do business with a founder. It would be great for important and large businesses to be walking distance within Berkeley.
In short, Berkeley is an incredible source of scientific creativity and business potential. Being relatively ignored but connected to a center of capital, Berkeley has the opportunity to create the world’s next important companies.
