Strategic Account Manager

We’re Summize, an ambitious legal tech scale-up based in the US and UK, working with businesses all over the globe. Our mission is simple, to get entire businesses working faster and smarter with contracts. We’re a growing team making big things happen out of HQs in Manchester, UK, Boston and San Diego, US and we’re not stopping! Following our recent $50 Million Series B investment we’re looking for forward‑thinkers, innovators and problem solvers to join our dynamic team as we enter our next growth phase.

The Role

This is a commercially focused role for a driven account manager who knows how to grow revenue and build lasting relationships. As a Strategic Account Manager at Summize, you’ll own a portfolio of our most important customers driving expansion, negotiating renewals, and positioning Summize as an indispensable partner within their business.

You’ll bring a commercial mindset to everything you do, with a strong instinct for identifying growth opportunities and a genuine ability to build trust at senior levels. Customer success is at the heart of this role, but the primary measure of your impact will be revenue growth and retention across your accounts.

• Own and grow a portfolio of strategic accounts, with a clear focus on net revenue retention, expansion, and upsell.
• Lead commercial negotiations including renewals, upsell, and multi‑year agreements, in close partnership with the Sales team.
• Identify and develop expansion opportunities within existing accounts, understanding the wider business to uncover new use cases and stakeholders.
• Build and maintain strong executive‑level relationships, acting as a trusted advisor and strategic partner to your customers.
• Drive platform adoption and ROI to underpin commercial conversations and strengthen account health.
• Lead executive business reviews that demonstrate value, align on strategic goals, and create the conditions for growth.
• Proactively identify at‑risk accounts and develop targeted plans to protect and recover revenue.
• Serve as the primary point of contact between customer and internal teams, ensuring a seamless experience across all touch points.
• Track and report on key commercial and success metrics including NRR, GRR, expansion pipeline, and customer health.
• Share customer insight and market intelligence with Product, Marketing, and Leadership to inform strategy.

• Approximately 3–5 years of experience in a strategic account management, enterprise sales, or senior customer‑success role with a strong commercial focus.
• A proven track record of hitting and exceeding revenue targets — upsell, expansion, and renewal — within a B2B SaaS environment.
• Experience managing senior stakeholder relationships and navigating complex organisations.
• Commercially sharp — you understand how to build a business case, lead a negotiation, and close.
• Strong understanding of the full customer lifecycle, from onboarding and adoption through to renewal and expansion.
• Excellent communication and presentation skills, comfortable operating at C‑suite level.
• Solid understanding of complex business processes and how software drives operational value.
• Familiarity with Customer Success platforms (ideally Planhat) and CRM tools.
• Highly organised, data‑driven, and proactive in managing your portfolio.
