What he walked into. Given his performance at ChannelAdvisor, Sean was assigned the "A-team" — the largest clients, the most reputable brands, the highest ARR and GMV. The expectation was retention and expansion at scale.
What he did. Sean drove adoption, retention, and expansion across 75 accounts. He designed account planning routines, escalation processes, customer health visibility, and engagement models. He partnered with strategic sales on deal strategy and customer positioning (the $589K side-project story lives inside this role). He coached the team relentlessly.
In his words: "This role really strengthened my ability to properly lead people in sometimes difficult situations and big wins. I found my passion for working with great people and leading them. I loved the coaching aspect of this role and found that I am very gifted at it. They challenged me every day but I loved it. These were truly transformative years for me, and I look back still on learnings that I have come to realize years later after leaving the company. This was my favorite and most rewarding role of my career."
