Partner - Data Science & Marketing Effectiveness, London

Associate Partner/Partner, MMM & Marketing Effectiveness London, UK

01About Ekimetrics

Ekimetrics transforms how organisations make critical business decisions. We combine our Eki.Decisions platform with embedded experts in marketing, commercial effectiveness and data science, connecting decisions across business domains to drive real, scalable and lasting impact. Our dual purpose is Competitiveness and Sustainability, because lasting leadership is built on both.

With a full in-house team and offices in Paris, London, New York, Hong Kong and Shanghai, we are committed to responsibility and frugality in AI, and to staying loyal to our values and DNA.

02The opportunity

Marketing budgets are under the microscope, CFOs want proof, and AI is rewriting how performance is measured. Ekimetrics sits at the centre of that shift. Since 2006, we have helped some of the world’s leading brands turn Marketing Mix Modelling (MMM) and AI-powered measurement into confident investment decisions.

As an Associate Partner, MMM & Marketing Effectiveness, you will be a senior leader of our London office. You will own a portfolio of strategic clients, shape how we grow our MMM and marketing effectiveness business in the UK and build the next generation of Ekimetrics talent. You will work alongside the London General Manager and be trusted with increasing autonomy and strategic ownership.

• Lead pitches and RFPs to win new logos and keep a strong pipeline.
• Be the face of Ekimetrics in the market: speak at conferences and client forums, and lead thought leadership on the future of measurement, including AI and GenAI.

Build the team and the UK office

• Lead by example, managing and coaching a team through regular 1:1s, performance reviews and talent assessments.
• Play a key role in recruiting, developing and retaining top talent in London, and in succession planning for the office.
• Contribute to our upskilling strategy with the Eki Academy team, and help shape the strategy of Ekimetrics globally and in the UK.
