Vancouver’s Fitplan, a personal training app that connects its members to world-class trainers for their workout plans and, is teaming up with a group of prominent investors: baseball great Alex Rodriguez, VC fund Corazon Capital, and fitness mogul Mark Mastrov.

The USD $4.5 million funding round was co-led by Corazon Capital, a VC fund that includes tech operators Phil Schwarz, former Chief Marketing Officer of Tinder, and Sam Yagan, co-founder of OKCupid and former CEO of Match Group.

Existing investors Lerer Hippeau, Bullpen Capital, Imaginary and Advancit Capital also participated in the round.

Said Schwarz, “Tinder aimed to improve people’s lives through relationships; we’re excited about the parallel potential in Fitplan to improve the lives of its members through fitness.”

Launched in 2016 by Cam Speck and Landon Hamilton, Fitplan’s training routines range in both length and intensity and are meant for all levels of experience, from beginner to fitness pro.

Workouts range from 20- to 30-minute routines, tailored for those crunched for time, to more intense 90-minute workouts, to extended multi-week plans.

The latest investment will be used to enhance product development and add more athletes to one of the fastest-growing fitness apps available.
