Customer Success Manager

Customer Success Manager | B2B Media & Marketing
London | Hybrid Working – 2 days a week | Permanent
45,000 Basic + 20% Bonus (54,000 OTE)
Are you a commercially minded relationship builder who loves understanding what makes businesses tick and helping clients achieve real results?
I'm recruiting for a fantastic Customer Success Manager opportunity with a growing, international B2B media and marketing business.
This is a role where you'll do far more than manage accounts. You'll become a trusted advisor to senior stakeholders, helping businesses maximise their marketing investment, deliver measurable ROI and build long-term commercial partnerships.
Working across a diverse portfolio spanning technology, finance and procurement to name a few , you'll gain exposure to a variety of businesses, commercial challenges and marketing strategies.
And importantly, you don't necessarily need to come from a traditional Customer Success background.
The Opportunity
You'll take ownership of an established portfolio of B2B clients, working closely with account management, sales, marketing, content and data teams to ensure campaigns deliver meaningful business outcomes.
From onboarding and campaign planning through to performance analysis, optimisation and renewal, you'll be at the heart of the client relationship.
This is a highly visible, commercially focused position where your ability to build relationships, understand business challenges and demonstrate value will directly influence client retention and growth.
What You'll Be Doing

• Owning client relationships: Managing a portfolio of approximately 60–70 accounts, including high-value strategic partnerships.
• Driving client success: Understanding clients' commercial objectives and ensuring marketing campaigns deliver against agreed KPIs.
• Maximising retention: Building lasting relationships, identifying risks early and proactively improving client engagement.
• Demonstrating ROI: Using campaign analytics, performance reporting and commercial insight to show clients the value of their investment.
• Becoming a trusted advisor: Engaging with senior sales and marketing decision-makers, providing recommendations and challenging thinking where appropriate.
• Working collaboratively: Partnering with internal sales, content, marketing and data teams to deliver an exceptional client experience.
• Improving the customer journey: Bringing fresh ideas to account management, client retention and customer success processes.
• Building relationships face-to-face: Attending relevant client meetings and industry events, alongside regular virtual engagement.

Who Would Be a Great Fit?
I'm particularly interested in speaking with people who combine strong relationship management skills, commercial awareness and genuine curiosity about how businesses operate.
You might already be working in Customer Success, or your background could be in:

• Account Management or Client Services
• B2B Media, Publishing or Marketing
• Commercial Sales or Sponsorship
• Marketing Operations or Campaign Management
• Client-facing Project Management

What's more important than your job title is your ability to understand complex client challenges, communicate confidently with senior stakeholders and take ownership of delivering outcomes.
You'll ideally bring an understanding of B2B marketing, confidence working with data and performance metrics, and the ability to manage multiple client priorities.
Above all, you'll be proactive, personable, commercially astute and comfortable rolling up your sleeves to get things done.
