TactioHealth -- Montreal, Quebec, Canada
Tactio is a health and fitness app company with a large portfolio. The company also sells third-party connected devices on its online store. Tactio apps track weight loss, blood pressure, activity, and diabetes. The company has never before built original hardware, though, so it's likely that it's in the competition with the intention of joining forces with another team.

Splendo -- Wassenaar, The Netherlands
The Splendo Foundation is a Dutch company founded just this year. The company seems to be seeking a partner in the competition. "Splendo ... hopes that the Qualcomm Tricorder X PRIZE will encourage participating teams to share knowledge and ideas to ensure the perfect Tricorder actually comes within hand's reach," they write on their website. "The result of the commitment in each team, but also that of the joint teams, will therefore be higher than the sum of its parts."
Team Gen Z -- Bellevue, Washington
Although Tricorder lists the team leader as Catherine Wong, Viirre tells us this team is actually led by Jack Andraka, the 16-year-old who famously invented a cheap and accurate sensor for detecting pancreatic cancer last year, winning the 2012 Intel Science Fair. Andraka's team is (or at least was as of March, according to the Daily Mail) made up of all teenagers, working remotely from around the world.
