  • Identifying and Developing Client Opportunities: You'll proactively identify where expanded consultancy can add value — growing relationships organically through relevance and trust.
  • Enabling a High-Performing Consultancy Team: You'll lead and mentor a team, fostering a consultative culture built on intellectual rigour, client empathy, and continuous learning.

What we want from you:

  • Analytics Consultancy Expertise: A proven track record of advising senior stakeholders and delivering recommendations that influence real strategic decisions.
  • Deep Analytical Fluency: The ability to engage meaningfully with sophisticated analytical methodologies.
  • Trusted Relationship Building: Demonstrated success in developing genuine, long-term advisory relationships.
  • Strategic & Commercial Acumen: Experience identifying growth opportunities through consultative insight.
  • Industry Knowledge & Intellectual Curiosity: Deep grounding in marketing effectiveness and analytics.
  • Values Alignment: A natural alignment with core values: Be Curious, Be Positive, Act with Consideration, and Make it Better.

  • Depth and quality of strategic advisory relationships with senior client stakeholders.
  • Demonstrable value and strategic influence delivered to clients.
  • Exceptional client satisfaction.

  • Gain Theory's Data, Analytics and Operations community, plus New Business and Strategy teams.
