About
A syndicate position, taken seriously.
In 2016, a four-person team in Menlo Park began deploying capital from Taiho Pharmaceutical’s first venture fund. The syndicates they joined were already crowded — seed and Series A rounds for early-stage oncology assets routinely included ARCH, GV, MPM, Pfizer Ventures.
What Taiho added was something the founders had not been asking for, and the lead VCs had not been able to offer: the credibility of a $400M Japanese specialty pharmaceutical company on the cap table. Ten years later, that has turned out to be harder to find than money.

Series A and B. Sometimes earlier.
Most rounds close on a term sheet. A few close on a thesis about who the founder wants on the cap table ten years from now. We are usually in the second category, and often the third or fourth name on the wire.

Taiho on the cap table, not just on the masthead.
Joint diligence with Taiho Pharmaceutical on clinical-stage investments. The result is a Series A or B board with American venture firms and a Japanese pharmaceutical company in the same room, before the round closes.
