Our firm brings Silicon Valley access and experience to Los Angeles, an emerging biotech community that is fresh, unorthodox and exciting. From Silicon Beach to some of the most successful startups in biomedical history, the City of Angels is in the midst of becoming one of the world’s biotech hubs.
We are playing our part catalyzing the biopharma industry not just in the LA region but beyond. Technology can come from anywhere and we match our company building skills with interested entrepreneurs or academic centers.

From a leadership team that combines complementary skills in science and business with a track record of developing breakthrough products and high-value companies unlike anyone else in the life sciences venture community, we are forging new paths incubating and building life sciences companies that have the potential to bring transformative therapies and technologies to patients.
We want to work with people who have that same entrepreneurial spirit and passion to help patients in need; people who seek to push the boundaries of science and technology.
How we can help
We care about patients and impact on human health. We always keep the patient front of mind.
We are entrepreneur friendly. We work to bring new ideas to life through hands-on support and expertise.

We are fair. We understand the team is the first and best asset. We are partners. We want you to be part of the whole process. We want you to have skin in the game and know that we are on the same team. We cannot win unless you win.

We have access to a broad and deep talent pool, additional funding resources, government, academia, large biopharma as well as private companies.

Our partners have developed new medicines at large pharmaceutical companies and smaller venture-backed startups. Our capital comes from the same institutions that are leaders in life science research.
We know that good ideas can come from anywhere. Our culture is one of openness, deep curiosity, transparency and honesty.
It is a two-way street…

New technologies and therapeutic approaches. We have broad and deep scientific expertise to nurture startups in virtually any therapeutic area of medicine and in all drug modalities.
Entrepreneurs with breakthrough ideas who want partners in building companies and getting their technology to patients as soon as practicable. We are open to anything that is new and focuses on a serious unmet patient need.
