He lives in Jersey City Heights with his wife, a good amount of handmade furniture, and a somewhat fussy coffee setup. He was born in Pittsburgh.
On a good day, he looks something like this.

He likes tech, music, podcasts, and biking the Empire Trail. He used to put his dog Paulie into a public dog house.
Marc enjoys writing with stationery, drawing stationary objects, and reading non-fiction books.
He frequently identifies typos on the website Daring Fireball. (He frequently gets prompt remedies, too.)
He used to have his own clothing company. It was called bminus.
If all that sounds vaguely impressive, remember that he's just like anybody else.

"If someone were stalking me, I'd want it to be someone like [Marc]!"
Peter Wagener. CTO. Received via email (out of context). 2026.
"I worked with Marc at CardFlight and always appreciated how easy he was to partner with. He has a great balance of creativity and practicality, and he consistently found ways to move projects forward in a way that actually worked for the business and the team.
"Marc is also an excellent communicator. He had a real knack for putting complex ideas into clear, straightforward updates for a group like Finance, which made decision-making faster and smoother for everyone. On top of that, he was always willing to roll up his sleeves and help out—even with projects that were a little undefined or outside of his “official” scope. You could always count on him to step in, bring structure, and get things done.
"He's the kind of teammate who makes work both more effective and more enjoyable. Any team would be lucky to have him."
Neha Patel. Finance VP. LinkedIn recommendation. 2025.
"Marc's tinkerer mindset was demonstrated through the curiosity and seeking for solutions in every approach to the PayFac business. He got an early start to scoping a persistent marketing identifier and helping us identify the type of professional assistance we will need for acquisition."
Janet Frasier. Marketing VP. Performance review excerpt. 2022.
