If you’ve been looking to join a fast-growing startup with a bold vision of a world where doing good is built into everything we do, then you’ve found the right place! Backed by General Catalyst, we’re one of Europe’s fastest-growing SaaS companies – building the technology that enables global enterprises to give, volunteer, and fund with confidence.

Our Mission

Our mission at Goodstack is to revolutionize how the world does good. As a Series A social impact startup, we power global change through technology. We enable companies to seamlessly integrate positive impact into what they do through a unified platform while supporting nonprofits in gaining access to cutting-edge technology and finding new funding streams.

Global brands, including Google, OpenAI, TikTok, LinkedIn, HSBC, Atlassian and Twilio - as well as thousands of nonprofits, including the Red Cross, Cancer Research, and Oxfam - use Goodstack to make a difference. In 2025 alone, we have facilitated $5 billion in donations to good causes. But this is just the beginning. We’re building the world’s leading platform that powers donations to nonprofits globally.

To keep our momentum and deliver consistently high value to our partners, we need incredible people to help us on our journey – we need you!

As a Customer Success Manager, your mission will be to:

• Own the customer relationship post-launch: Become the primary point of contact once live and run a structured operating cadence.
• Drive adoption and outcomes: Ensure usage, engagement, and program performance are moving in the right direction.
• Run day-to-day service with high standards: Manage requests, unblock friction, coordinate internal teams, and keep the customer confident.
• Lead renewals end to end: Own the renewal process, timeline, stakeholder alignment, negotiation, and close.
• Deliver upsell growth: Expand the existing product footprint (volume, usage, geographies, terms) tied to value delivered.
• Spot and qualify cross-sell opportunities: Identify whitespace for new products, validate need, and bring in the AE to execute the sale.
• Build executive trust: Maintain strong sponsor relationships and ensure senior stakeholders stay aligned to value.
• Control noise and complexity: Ensure customers experience one coordinated Goodstack team and clear ownership.
• Operate commercially and predictably: Keep account plans, renewal forecasts, and expansion signals documented and up to date.
• Be a strong internal advocate: Translate customer needs into structured feedback for Product and Solutions without creating chaos.

After 12-18 months, success will look like:

• Your book of business is healthy, stable, and adopting — with clear value metrics and stakeholder alignment.
• Renewal cycles are run early and cleanly, with high retention and minimal escalations.
• You consistently grow existing customers through upsell (usage, volume, geography, terms) based on value delivered.
• You surface high-quality cross-sell opportunities that convert because they’re well qualified and well timed.
• Customers describe Goodstack as organized, responsive, and commercial — with a "one team" experience.
• You are trusted internally as someone who runs accounts with discipline and judgment.
• You’ve built a repeatable success rhythm that others can learn from and replicate.

This role is a perfect match for you if you have:

• Commercial and customer led: You care about retention and growth, and you know how to do both without damaging trust.
• Highly organized: You run tight cadence, clean documentation, and predictable outcomes across multiple accounts.
• Confident in renewals: You can handle negotiation, procurement, and stakeholder alignment without hesitation.
• Outcome driven: You focus on measurable adoption and value, not activity for activity’s sake.
• Calm under pressure: You manage escalations and conflicting stakeholder priorities with composure.
• Clear communicator: You simplify complexity and keep customers aligned without overloading them.
• Proactive: You anticipate issues before they become problems and act early.
• Collaborative: You know when to pull in Implementation, Solutions, or the AE — and when not to.
• High standards: You deliver a premium experience consistently, even at pace.
• Mobile: Willing to travel across North America and to London several times a year.

Ideal experience:

• 5–10+ years in enterprise Customer Success, Account Management, or post-sales roles in SaaS.
• Proven ownership of renewals and commercial negotiations in enterprise environments.
• Strong track record driving adoption and value realization across complex stakeholder groups.
• Experience supporting high-touch enterprise programs with technical or operational complexity.
• Comfortable working cross-functionally with Product, Solutions, Implementation, and Sales.
• Strong use of structured customer success frameworks (success plans, health scoring, QBRs).
• Evidence of progression and increasing responsibility in fast-growing environments.
• Based in Central or Western North America, with flexibility to travel regularly.

Bonus if you have knowledge or love of:

• Corporate giving, CSR, philanthropy, or nonprofit ecosystems.
• Working with HR/People, CSR, or Corporate Affairs teams.
• Multi-product SaaS platforms with workflow-heavy implementations.
• Operating in Slack-based customer environments.
• Translating customer insight into structured product feedback.
