Growth Portfolio Director

Growth Portfolio Client Partner

Location: London (hybrid), with regular UK client travel
Team: Client Partner Team (across Kantar Domains)
Contract: Permanent
Comp: Includes an annual individual revenue target (upsell & cross‑sell)

Primary Objective

The Portfolio Growth Partner is the growth catalyst for a portfolio of high potential clients. This role sets bold, client centric growth strategies, hustles relentlessly for new opportunities, and proactively hunts for new buying points across and beyond insight functions. By deeply understanding each client’s sector, business performance, and strategic priorities, the Portfolio Growth Partner identifies untapped opportunities and threats and turns them into meaningful commercial impact.

Core Responsibilities

1. Strategic Growth Leadership

• Develop and execute bold commercial growth strategies for a portfolio of high potential accounts.
• Use deep knowledge of the client’s business, category trends, and competitive context to anticipate opportunities and threats.
• Act as a strategic sparring partner for senior client stakeholders, shaping big‑bet initiatives that transform client performance and strengthen Kantar’s strategic influence.
• Use Growth Compass insights to inform ways to support the client and identify next volume of cross-sell action.

2. Portfolio Driven Client & Commercial Acceleration‑Driven Client & Commercial Acceleration

• Own the full commercial agenda for each client relationship, including revenue delivery, pipeline development, cross‑sell strategy, and deal execution.
• Proactively hunt for untapped buying points both within and beyond insight teams—marketing, strategy, innovation, digital, analytics, finance, and more.
• Diversify and deepen relationships using the 3E model:
  • Elevate relationships to increasingly senior decision‑makers.
  • Expand relationships across new stakeholders and functions.
  • Embed insights with end users to strengthen day‑to‑day value.
• Assess white‑space opportunities and introduce innovative Kantar capabilities to address them, ensuring clients benefit from our newest solutions and approaches.
• Use the Deal Compass to strengthen bid strategies, drive win rates, and close growth opportunities faster.
• Demonstrate hustle behaviours, showing urgency, persistence, resourcefulness, and a bias for action to create commercial momentum.

3. Innovating for a Changing Client Context

• Collaborate with Kantar SMEs to activate opportunities across all client solution areas
• Identify compelling breakthrough capabilities to take to clients, strengthening long‑term growth.
• Create a culture of energy, curiosity, commercial sharpness, and partnership.

4. Market & Capability Expertise

• Maintain a strong working knowledge of the full Kantar portfolio and emerging market trends.
• Bring the best of Kantar to clients by connecting them to the right experts, capabilities, and solutions.
• Ensure external signals (competitive moves, category evolution, macro shifts) are integrated into client growth planning.

What This Role Is Not

To sharpen clarity and expectations, the Portfolio Growth Partner is not:

• A delivery or project‑management role responsible for day‑to‑day execution, nor insight delivery
• A reactive order‑taker waiting for briefs, or a co-ordination role. The emphasis is on external activation, influence, and commercial acceleration. It requires proactive commercial creation, not stewardship alone.

Essential Knowledge & Experience

• Proven experience managing multiple accounts with strong growth potential.
• Demonstrated commercial acumen and ability to deliver ambitious revenue targets.
• Strong track record of building senior, multi‑stakeholder client relationships.
• Experience identifying and activating cross‑sell opportunities in complex client environments.
• Ability to apply sector knowledge and insight to shape client strategy.

• Experience in relationship building and stakeholder diversification.
• Ability to synthesise complex client and market signals into clear strategic direction.

Success Measures (KPIs)

• Portfolio revenue growth (delivery beyond annual plans).
• Strength and breadth of senior client relationships.
• Expansion into new stakeholders and functions.
• Quality, scale, and velocity of pipeline.
• Conversation volume and commercial momentum.
• Programme retention and cross‑sell penetration.

Kantar Success Factors (behaviours)

• Leads with Impact. Owns Commercial Success, Solves Problems Decisively, Connects to Win, Builds Great Teams, Drives Lasting Change, Amplifies Professional Expertise.
