One Nucleus
One Nucleus is arguably the premier network for the Biomedical and Life Sciences sectors in the area. They are not startup-focused, although they provide paid membership options from sole-traders up to large corporations. Membership is not cheap - but could be particularly useful if you’re in the scaleup phase in these sectors.
Founders Growth Community
The Founders Growth Community is a collaborative network for early-stage life sciences and biomedical startups.
