Global Reporting and Analytics Lead, Client Partner in London

Company Description

Who We Are in the UK? Spark Foundry, the Acceleration Agency. We help brands to identify, learn and respond to opportunities faster than the competition. Every client has an area of their business they need to accelerate, from short-term goals to long-term transformation. We’ve proven our approach during the most difficult year on record. Now we’re using it to provide a launchpad for their future. Come be an accelerator with us.

How we accelerate:

• Planning: an approach that works in practice rather than theory, arming planners with the ability to create cutting edge campaigns.
• Intelligence: a suite of tools that give definitive answers to big questions, and uncovers actionable insights about real people.
• Trading: a model built on flexibility and trusted relationships, underpinned with bold guarantees.
• Relationships: a culture of asking challenging questions to better understand the brief – we are not a ‘yes’ agency.
• People: a strong history of recruiting talent from diverse backgrounds and accelerating their careers.

Our Commitment: We are diverse through our experience, people and the clients we look after - and we celebrate that diversity. Our people hold us accountable to our beliefs and via regular surveys and our grass roots D&I team, The Collective, and internal next generation board, Firestarters, we hold regular events and work continually towards generating ideas, initiatives and educating our people to ensure we are a diverse and inclusive agency.

As part of our dedication to create an inclusive and diverse workforce, Spark Foundry is committed to equal access to opportunity for people without regard to race, age, sex, disability, neurodiversity, sexual orientation, gender identity or religion.
