The bullets are metric-driven. The "View AI Context" expansions are the unvarnished story — what was broken, what he actually did, what almost went sideways.

Manager, Client Success — ChannelAdvisor (2017–2019)

  • Led a 12-person team accountable for 75 enterprise and mid-market customers, $12M ARR, and hundreds of millions in GMV across Amazon, eBay, Walmart, Target, and 25+ marketplaces.
  • Created training and operating standards adopted across a 125-person services org spanning NC, CO, and Shanghai.
  • Built a consulting service tier for smaller customers — $50K in new revenue, $100K retained in net revenue.

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."

Success Team Lead, China Marketplaces — ChannelAdvisor (2014–2017)

  • Helped launch ChannelAdvisor's Shanghai office (40 employees, $4M year-one target). Trained client-facing teams on product, services, and integration workflows.
  • Hired and trained the first Client Strategy Manager in region.
  • Co-designed a brand-new China services model — approved by senior leadership and rolled out across the region.
View AI Context ↓

What he walked into. ChannelAdvisor had recently opened Shanghai. The new GM had founded the office, hired teams, and started the business — but there were significant gaps in product knowledge, service knowledge, and localization. Sean had asked the Director of Services to volunteer if the opportunity ever came up.

What he did. Months later he was asked to spend three months on the ground in Shanghai. He didn't speak Mandarin, and being away that long was a significant personal commitment, but he saw it as a once-in-a-lifetime opportunity. He worked side-by-side with the China GM, hired and trained the first Client Success manager in China, ran client visits across China to learn what was working and what wasn't, trained Client Success, Sales, Account Management, and implementation teams in the Shanghai office, and worked on-site with the largest customer in region to prevent them from churning — ultimately saving the business.

A year later he returned for another two months to train a new Director of Services and co-design a brand-new China services model. Upon his return to the US, the new model was approved and implemented. He returned a few more times in subsequent years to support hiring and work with Chinese customers directly.

In his words: "This was by far the most rewarding experience of my career."

$589K "side project" sales partnership — ChannelAdvisor (2017–2018)

  • Closed $589K in new bookings in six months as a side project — entirely outside core responsibilities.
  • Trained members of his own team to support sales the same way, then built the company's permanent sales enablement function for services.
View AI Context ↓

What he walked into. Leadership at ChannelAdvisor was frequently asked if someone from services could join sales calls to help pitch the offering. The sales team didn't always understand the depth of what Managed Services delivered and had trouble selling it. Sean saw the gap and started joining calls to support the AEs.

What he did. The calls went well — so well that he was asked to join more and more of them, eventually being invited only to the most strategic deals with the largest brands. He traveled with the strategic sales team to help close deals and present to prospects. At one point he was actually "hand-slapped" by his own management for spending too much time on consultative sales outside his core scope — though leadership was simultaneously happy about the deals he was helping close.

He then trained members of his own team to support sales in this capacity as well, scaled the effort, and ultimately drove a sales enablement initiative within the company so the AEs themselves could be trained on the services. The whole effort started informally and ended as a structured enablement program — all of it built by Sean.

Managed Marketplace Services consulting tier — ChannelAdvisor (2018)

  • Built a new consulting tier within Managed Marketplace Services that generated $86K in new revenue and $206K in additional bookings within six months.
  • Personally pitched on sales calls and trained AEs to sell the new offering.
View AI Context ↓

What he walked into. Sean had repeatedly noticed that the Managed Services team was doing consultative work that fell outside scope. As customers added sales channels and programs, the work grew correspondingly more complex. The nature of enterprise customers also demanded more advisory work. Sean began studying what other SaaS and consultative firms charged for that same depth — and realized the gap was significant.

What he did. He pitched the opportunity to leadership with a full rollout plan and resource requirements. He presented the business case clearly: a new revenue stream and a service larger customers were already asking for. Leadership approved. He selected the right team members to execute, consulted with subject-matter experts, and personally joined sales calls to pitch the consulting offering. He trained sales executives on how to sell it — earning their buy-in by giving them another product they could close on.

Result. $86K in new consulting revenue and $206K in additional bookings within six months, specifically with Amazon marketplace sellers.

Senior Client Engagement Manager — Pitney Bowes Global E-Commerce (2021–2022)

  • Led executive stakeholder alignment to complete a high-stakes Amazon Global RFP — retained existing business and won new EU lanes worth $3M annually.
  • Identified business risk threatening a key client relationship, coordinated cross-functional resolution, and unlocked $4M in previously unattainable new business.
  • Combined portfolio across cross-border and domestic delivery: ~$200M in annual revenue.
View AI Context ↓

What he walked into. Sean had just taken over the Amazon Global account roughly a month before Amazon requested an RFP. Pitney Bowes already had a healthy chunk of the business, but this RFP required winning it back or losing it all. It was Sean's first official RFP and he was admittedly intimidated.

What he did. He learned the account inside and out, understood how every Pitney Bowes service was working for Amazon logistics into every country, and built cross-functional relationships with people in finance, legal, tech, engineering, and the warehouse facilities themselves. It was a significant cross-functional project-management effort. There were tight timelines, missteps from other departments, corrections, pivots, and significant internal messiness — all of which Sean had to navigate. His calm temperament and strategic mindset allowed him to hold the effort together.

Result. Won back the existing business and secured new EU lanes worth $3M annually.

What he's strong at. What he's not.

Most candidates list everything as a strength. Sean lists his gaps explicitly. The credibility comes from naming what he isn't.

Strong
On-stage expert. Reaches for it daily.
  • E-commerce strategy & marketplace operations (Amazon, eBay, Walmart, Target, 25+ marketplaces)
  • Customer Success leadership — NRR, retention, expansion, churn reduction at scale
  • Cross-functional execution under tight deadlines (legal, ops, finance, compliance)
  • Executive stakeholder management & QBR design
  • Services delivery, design, SLA management, escalation handling
  • Team leadership, coaching, hiring, performance management
  • Cross-cultural leadership (US / China, multi-year on-site)
  • Onboarding & implementation framework design
  • AI-enabled workflow automation (n8n, Make.com, Claude, agentic workflows)
  • Sales enablement & consultative selling (the SME who closes deals)
  • Six Sigma process design / new service-model creation
  • Cross-border commerce & fulfillment operations
  • Operator and strategist mindset
  • High EQ
  • Presentations & public speaking at industry events
Moderate
Holds his own. Would pair with a specialist.
  • Salesforce administration (heavy user, not a certified admin)
  • Solutions Engineering / Pre-Sales (informal experience — has done ChannelAdvisor platform integrations: data mapping, API guidance, structure design)
  • B2B SaaS product roadmap input (co-developed at Mamenta)
  • Pipeline development / outbound sales (built systems, not a quota-carrying AE)
  • Strategic partnerships
  • Data analytics (deep Excel, lighter on Tableau / Looker / SQL)
Gaps
Explicitly not claiming. Hire a specialist for these.
  • Software engineering / hand-written code — orchestrates, doesn't program
  • Frontend / UX / visual design
  • DevOps, cloud infrastructure, Kubernetes
  • ML model training / fine-tuning — uses LLMs, doesn't train them
  • Consumer product growth / B2C marketing at scale
  • Hardware / IoT
  • Government / regulated-industry sales

Is Sean a fit for your role?

"The hardest part of AI transformation in CS will not be the technology. It will be the behavior change."

For years, many CSMs — including many strong ones — succeeded through responsiveness, relationship management, follow-up discipline, internal coordination, and customer empathy. Those skills still matter. But they are no longer enough.

As AI absorbs the administrative layer of CS — meeting summaries, follow-up drafts, task creation, account research, health-score monitoring, basic outreach — the modern CSM has to move up the value chain. Diagnose customer risk. Interpret account signals. Connect product usage to business outcomes. Influence executive stakeholders. Identify expansion potential. Make better commercial decisions.

That shift requires coaching. Real coaching. Not just training on a new AI tool. The tools will arrive quickly. The workflows will change quickly. The dashboards will improve quickly. But getting CSMs to actually change how they think, prioritize, diagnose, and operate will take longer.

There will be a gap between teams that merely adopt AI tools and teams that use AI to elevate the CSM role. The CSMs who thrive will be the ones who use AI to become sharper account strategists, better customer operators, and stronger drivers of measurable business outcomes.
