What Stagebox does
Stagebox is a UK-headquartered performing-arts training and talent-management business serving children and young performers aged 8-18. Founded in Leeds in 2014 by Emily and LJ Keston — both active children's casting professionals and general managers at Keston & Keston — the company has grown from a local programme to a multi-city operation with physical training academies in Leeds, London (White City), Manchester, Birmingham and Dublin, complemented by global online delivery for its Acting and Singing offerings.
The company's core product is a three-tier membership portfolio. The flagship Musical Theatre Membership runs at £98+VAT per month and delivers four intensive training weeks per year during school holidays plus showcase filming, with ~35 students per regional centre and a documented 1% audition acceptance rate. The Acting Membership provides weekly screen-acting and dialect training in 30-week blocks, and the Singing Membership is a private vocal-coaching add-on delivered in partnership with Vocal Balance. Entry to all programmes is via audition, and an annual £50+VAT Administration Fee is charged to secure a member's place. Layered on top of training is Stagebox Management, an in-house talent-representation service that places members with major UK and US agencies (Gersh, Hamilton Hodell, Intertalent, Conway Van Gelder Grant, Paradigm) and production studios (Warner Bros, Netflix, Universal, HBO, BBC, Disney); placements cited include Wicked, Adolescence, Matilda, Oliver, Paddington The Musical and Supergirl. The Company Project Live is an annual in-person showcase event, with a 10-year anniversary staged at Leeds Playhouse.
Stagebox operates as a private limited company (Stagebox UK Limited, Company No. 09421415) registered in England and Wales, with no external investment or parent company disclosed. Revenue is generated from recurring monthly membership subscriptions, annual admin fees, Stagebox Management commissions, and an online store. Headcount is reported at 11-50 employees. Distribution is direct-to-consumer via website, discovery calls, and social channels, with the audition process as the conversion gate and 22 million cumulative content views cited as a brand-equity indicator.
