Matthew on "Why I Joined Matter"

I’m thrilled to be joining Matter, and here’s why:

The mission: I come from a family of educators, and learning and personal growth have always been a primary driver in my life. Matter’s ambitious aim, helping people to become a better version of themselves, really struck a chord with me. Frank, actionable feedback is essential to self-improvement, and Matter can have a huge impact on people’s lives by providing just that.

The people: In my first conversation with Brett I was struck by his ambitious vision, and enthusiasm for the mission — and his kindness and thoughtful style of communication were shared by all of the other people in the company that I met. The tech industry is filled with incredibly smart people, but kindness, candor, and devotion to self-improvement are qualities that make Matter’s people and culture unique.

The opportunity: Literally everyone in the world can benefit from good feedback. Removing the friction and uneasiness from giving and receiving that critical feedback is a massive opportunity. I’m excited for the chance to help build a company that could improve the lives of so many people.

Matthew’s expertise in building and scaling engineering teams will be essential for Matter success and our growing community of professionals. We’re incredibly thrilled to have Matthew abroad. Welcome Matthew!

Matter is for professionals who want to become the best version of themselves. We believe everyone deserves the opportunity to achieve mastery, learn, grow, and be respected by their peers. People perform better when they receive monthly peer feedback (proven by science too!). Matter makes feedback easier, pleasant, and more productive. Level up your career with Matter.
