Client Services Manager

About Audience Store

At Audience Store, we’re not just another programmatic provider. We’re audience-obsessed, data-fuelled, and creatively charged. Since 2013, we’ve helped brands discover new customers and unlock incremental growth by combining rich behavioural insight with precision programmatic activation.

Our proprietary planning tool, Discover AI, digs deeper than demographics—surfacing the mindsets, motivations, and moments that move audiences across the open web. That’s how we deliver media strategies that don’t just perform—they transform.

We’re a close-knit team, with a collaborative culture, and a genuine passion for helping brands grow. If you’re ready to be part of something meaningful, we want to meet you.

About the Role

We’re looking for a driven, detail-loving and strategically minded Client Services Account Manager to join our growing team. This is an exciting opportunity for someone with solid client-facing experience and who’s passionate about digital media, programmatic advertising, and building high-impact client relationships.

You’ll work closely with senior leaders and delivery teams to manage day-to-day client relationships, plan and oversee programmatic campaigns, and uncover new growth opportunities. You’ll become the go-to for your clients—someone who gets their business, solves problems before they arise, and always adds value.

What You’ll Be Doing

Client Relationship Management

● Own day-to-day client communications, building trust and demonstrating strategic value at every touchpoint

● Lead kick-offs, mid-campaign check-ins, and post-campaign reviews with insight-led storytelling

● Act as the key link between client stakeholders and our internal teams (sales, tech, creative, trading)

● Be proactive, solution-focused, and always one step ahead of client needs

Media Strategy & Planning

● Translate briefs into programmatic strategies that align with client KPIs

● Use planning tools, first-party data and audience insights to craft impactful media plans

● Collaborate with traders and performance specialists to optimise campaigns in-flight

● Deliver clear, compelling PCAs and business reviews that drive renewals and growth

Commercial & Operational Excellence

● Protect and grow client revenue through upweights, renewals and cross-sell opportunities

● Ensure timely forecasting and accurate reporting of financials and performance

● Maintain excellent internal process hygiene (status docs, briefings, timelines, POs)

● Spot inefficiencies and suggest new tools, tactics or services to improve our client offering

Team & Culture Contribution

● Stay ahead of industry trends, competitor activity and client category news

● Champion new ideas—from creative asset suggestions to smarter ways of working

● Support the sales team at events and new business meetings when needed

● Share learnings and successes with the team, helping us all level up

What We’re Looking For

● 3+ years of experience in a client-facing role within digital media, agency, or ad tech business

● Strong understanding of Programmatic Advertising and audience planning

● Exceptional communication, presentation and stakeholder management skills

● A proactive attitude with a creative, solutions-first mindset

● Highly organised with an eagle eye for detail and deadlines

● Confidence using Excel, PowerPoint, Outlook; bonus if you’ve used Adobe, Notion, or AI tools like ChatGPT

● Someone who thrives in a small, dynamic team and wants to make a big impact

Why Join Us?

● Flexibility – Hybrid working: WFH Mon/Tues/Fri, collaborate in-person Wed/Thurs

● Autonomy & Growth – Real responsibility, real impact, and real room to grow

● Innovation at Heart – Use AI, creativity, and insight to push boundaries

● Thriving Culture – Collaborative, curious, kind—and proud of it

● Central Office – Right by Warren Street and Great Portland Street tube stations (with great coffee and even better people)
