The rest of the 100 (in alphabetical order): William McKeon, president and chief executive, Texas Medical Centre, TMC Venture Fund

Just a few months after being promoted to president and chief executive of Texas Medical Centre – an organisation whose members include a large number of local universities and research bodies – William McKeon oversaw the launch of the $25m TMC Venture Fund.

The fund, formed in November 2017, has been created to identify and support technology investment opportunities in the healthcare sector in and around Houston.

Before joining TMC as chief operating officer in 2013, McKeon ran medical technology businesses in both the UK and China after amassing considerable experience at US-based organisations including conglomerate DuPont and Stanford University Medical Centre.

Among the initial wave of companies backed by the fund are clinical-trial platform Medable and surgical tool developer Briteseed.

Earlier this year, cardiac device firm CorInnova and Intelligent Implants, a developer of implantable bone growth monitors, each received $250,000 seed investments from the fund after participating in TMC’s JLabs incubator, a partnership with healthcare group Johnson & Johnson.
