Writing
All posts ↗Recent posts focus on biotech startups and founders: observations from a trip through China's biotech ecosystem, advice on fundraising for founder-led biotech companies, and reasons industry scientists should consider starting startups.
The author recounts a two-week trip meeting Chinese biotech founders and investors, finding costs less discounted than expected, company-building less mature than top US firms, and potential for US-China collaboration.
Drawing on raising roughly $100 million, the author explains the current biotech funding landscape, emerging investor categories favoring founder-led companies, and how to tell a compelling, accessible fundraising story.
The author argues industry scientists are well positioned to found startups, citing exposure to real problems, operating experience, co-founder access, and favorable timing during a market downturn.
