Raj and I just dropped the 2026 Semper Maior report. 20 years of M&A lessons a massive deep dive into deal data since 2019. Lot's of hard-earned lessons in here. Read it on your way to JPM before your strategic meetings. Good luck out there! #JPM2026

At Trace, we think every person should have access to proper treatment for their disease, including those with #ALS. On #LouGehrigDay, we join @NPLB_org in their mission to make medicines affordable for every patient in America. @ercgrn joins fellow biotech leaders to share more.
ALS is relentless. So are the patients and research teams fighting it. For the 30,000 Americans living with amyotrophic lateral sclerosis, every day matters. New treatments are on the horizon! 🎥 nopatientleftbehind.org/our-… #ALS #ALSAwareness #FixInsurance #Biotech #Innovation #HealthPolicy

RA Capital Management's @t_lorriman on @tbpn talks biotech entrepreneurialism in the US and China.
12 May 2025
We asked @t_lorriman about biotech startups. "The entrepreneurial process for biotech is too institutionalized." "Ideas (mostly) come out of academic and venture funds. Because biotech is so high-risk and capital intensive, there's more of an institutional process to start a company than in tech." "China has a fundamentally different cost base and pace of iteration. There's a lot of work we need to consider for our biotech ecosystem to adapt."

Massachusetts leads the world in biotech—yet its own leaders often criticize the industry that powers the state's economy and develops the new medicines we all depend on. Why? Over 1,000 companies, 100,000 jobs, and a mission to save lives. 📺 Watch: The Massachusetts Paradox
