From Our Team
The Mysa team is dedicated, diverse, and determined to lead locally and globally in developing smart home tech that helps our customers AND our planet.
Here’s what inspires our peeps to keep crushing it.
Moustafa (He/Him)
“*Cue car ad music* A vital mission, a performant team, a great culture — all homegrown in Newfoundland and Labrador. I believe that we’re working towards a goal that our planet’s future depends on. We have the tools to act quickly on our mission, and the people to make it a fun and memorable experience along the way. That’s what makes Mysa so special!

Seriously, though — I worked at a bunch of tech companies before I graduated in 2019, from tiny startups to a tech giant. I joined Mysa when we were just 20 employees, and I have enjoyed every minute of it. Seeing how far we’ve come and knowing where we’re headed? I can’t think of anything more rewarding! :)”
Katy (She/They)
“I started my career at a company with close ties to the oil & gas industry, then went back to school knowing that I wanted to work with an organization whose values better reflected my own. Mysa was the perfect fit, and I’m SO happy I made the move when I did! Joining a team where everyone is not only supportive and fun, but also excited about developing tech for a greener world, has left me feeling more satisfied and fulfilled than any of my previous roles.”
Sarah (She/Her)
“Making the switch to Mysa from a more corporate environment was a win in many ways for me! Going from strict schedules and tracked time off to a flexible remote work policy with unlimited vacation was very attractive to me, as I believe it is for many younger employees these days.

Mysa’s people-first culture keeps me motivated, invested in team success, and has had an incredibly positive impact on my personal life and relationships. I’m learning about sustainable resources and becoming more aware of the choices we can all make to create a greener future — it feels great to know that my work is making a real contribution to fighting climate change.”

in equivalent greenhouse gas emissions.
Mysa Smart Thermostats have saved over

That’s enough to power 10,000 homes for a full year.
Let’s keep it growing.
The future is electric
Josh Green CEO, Mysa Smart Thermostats
“Our team is passionate about keeping our customers comfortable at home while we work together to advance the global shift toward electrification.

We’re incredibly excited to keep creating smart tech that helps our family of customers make easy, future-focused home energy management choices.”
Climate change demands response
Real change for our planet’s future demands real action today.

We’re working with electrical utility providers on Demand Response pilot programs that empower Mysa customers to help balance our electrical grids through smarter energy use during peak demand times.
What does it mean? Our customers stay comfortable and save on their electricity bills while stabilizing our electrical grids and helping lower carbon emissions.

We’re working on expanding our DR programs and partnerships with utilities across North America to help our customers save energy (and the planet).
Savings. Sustainability. Smart.

It’s not just about where we’re doing right now — we’re always focused on what’s next.
