Enterprise Customer Success Manager

Channext is a fast-growing channel SaaS scale-up based in Utrecht. Our platform is trusted by some of the largest technology companies in the world, including Acronis, HP, and Microsoft. We help vendors and their partners collaborate more effectively by automating marketing, streamlining content distribution, and improving performance insights. As we scale, we are seeking an Enterprise Customer Success Manager to own a portfolio of our key enterprise customer accounts and ensure Channext helps them achieve success. 🚀

As a Senior Customer Success Manager at Channext you’ll be a collaborative and strategic partner to our customers. Your focus will be on building strong relationships and owning enterprise customer outcomes end-to-end: driving program onboarding and adoption and proving measurable value impact through reporting, strategic insights and ROI. You’ll turn successful delivery and strong stakeholder engagement into predictable renewals and expansions.

• Build and own customer success plans: deeply understand your customers and their goals and translate these into clear success plans, drive value realisation and ensure customers consistently see measurable value.


• Lead program delivery and execution across teams: coordinate internal delivery (CS, agency/delivery, partner, product, data) to launch programs and campaigns on time, with tight expectation management.


• Deliver executive-level insights and QBRs: create monthly insight packs, regular strategic reviews and executive business reviews, that explain performance and high-impact next steps and actions.


• Identify recurring opportunities and challenges: leverage deep qualitative customer feedback and performance impact data to identify opps/challenges and collaborate with Product and Data teams to translate these into actionable platform and reporting improvements and product evolution.


• Own platform adoption, understanding and enablement: proactively build customer-facing enablement assets, run introduction/training sessions and guide customers on best-practices for tracking and reporting on insights.


• Drive proactive renewal readiness and upsells (with Head of CS): run stakeholder mapping, risk mitigation, and value proof 120/90/60/30 days ahead of renewal to make renewals and upsells predictable.

• 5+ years of experience in Enterprise Customer Success, Delivery/Implementation, or Post-Sales in a B2B SaaS environment, owning complex multi-stakeholder accounts.


• Strong delivery & program management skills: able to run structured plans, manage dependencies across teams, and consistently deliver on timelines and outcomes.


• Evidenced collaborative and communication ability: extremely effective at translating customer feedback and needs into clear and actionable input for product and data teams.


• Insight-driven communicator: highly analytical, comfortable with data and reporting, and able to turn performance into crisp executive recommendations and QBR storytelling.


• Structured and proactive: able to manage multiple customers and projects simultaneously.


• Proven track record driving renewals (and ideally expansions) through proactive value delivery, stakeholder management, and clear ROI narratives.

• You’ll own outcomes, not just relationships: full accountability for driving measurable ROI for enterprise customers—delivery, adoption, insights, and renewal readiness.


• Work with ambitious enterprise customers: complex, multi-geo programs where your structured delivery and executive communication genuinely move the needle.


• High impact, high visibility role: close partnership with the Head of Customer Success and commercial leadership, directly influencing retention and growth.


• Competitive salary & benefits: Competitive salary and benefits, 3% pension contribution, 25 vacation days with the option to buy 5 more, work from anywhere 4 weeks per year, annual learning and development budget, and regular team events such as our weekender, ski trip, boat trips and seasonal celebrations.
