About Sean Macmannis

I’m Sean MacMannis. I’ve quit, rebuilt, and designed a new life--on my terms.Now, my passion is helping high performers like you build a layoff-proof life & work on YOUR terms. ⛰️How I got here:After years leading growth in tech—Pinterest, Adify, Gitcoin—I took a hard turn: I wanted a career that actually fit my life. Today, through my work at my company Positive Sum, I help high performers escape the treadmill and build lives they truly own, not just the ones they work for. In my newsletter, ⛰️Trail & Error, I dig deep—exploring ambition, resilience, and the courage it takes to live your values. If you’re ready to create a career that doesn’t just look good but feels right, let’s connect. My DMs are always open and I love pointing people who feel STUCK get back on track. Let's do this!
