About Us
mello is a Y Combinator (S21) backed start-up that integrates wellbeing into every employees’ workflow in order to unlock their full potential. We are paving the path for the future of work. Our vision is to help every remote team on the planet to work healthier, more sustainably, and learn how to stay mello instead of burning out.
As second time founders, we burnt out building our last company during the pandemic. We wanted a simple, easy-to-use solution that integrates right into our workflow to increase our wellbeing but couldn’t find anything on the market so we decided to build the solution we would’ve liked to use ourselves (aka, eating your own dog food).
At mello, we’re building the new standard that remote and hybrid companies use to track, measure and act on burnout to inspire happier, healthier, more motivated teams. mello suggests smart actions for both employees, managers as well as HR to take to increase wellbeing, productivity and retention.
