ESE was founded by Leon Spellson in 1998 with a clear goal: to help brands create marketing moments that mean something — and that last. Since then, ESE has built a reputation for delivering innovative brand experiences across sport, entertainment and lifestyle, forming trusted partnerships with some of the industry’s most respected organisations.
In 2019, Leon joined forces with Kelly, bringing together decades of client- and agency-side experience, a deep love for sport and entertainment, and a shared belief in building relationships that go beyond the brief. Their leadership has shaped ESE into the business it is today — strategic, collaborative, and grounded in care.
ESE Management launched in 2021 under the leadership of Alexandra Williamson, expanding the agency’s offer into elite athlete and broadcast talent representation and bringing new energy, focus and long-term thinking to the way we support talent.
Today, ESE continues to grow — not in scale, but in impact — staying intentionally focused so we can invest deeply in every relationship.
