Burn Boot Camp Signs Marshmello as Equity Partner

Burn Boot Camp has brought on music producer Marshmello as an equity partner, franchise owner, and executive partner for creative and music. The artist will also open and operate his own Burn location. The deal follows a January agreement that made Kevin Hart an equity partner and franchisee, which marks this as a strategy rather than a one-off.

Ownership instead of endorsement

Most celebrity fitness tie-ins are paid endorsements that end when the contract does. Burn is structuring these as equity and operating roles, so the partner's payout depends on the brand's long-term performance. That alignment hands the franchise a marketing asset it no longer has to rent, and it puts a recognizable name behind real financial risk.

What franchisees actually get

For Burn's more than 400 locations, the prize is traffic and retention. Marshmello's role centers on music and member experience, launching June 29 with weekly Marshmello Mondays playlists. Group fitness depends on community and repeat visits, so anything that makes the room feel distinct can cut churn, which is the largest cost lever in any membership model.

The signal for other brands

Burn is testing whether cultural equity can be built into a franchise system rather than bolted on. If celebrity owners drive measurable lifts in joins and retention, competitors will copy the structure fast. The risk is dilution. A move that works with two partners loses its edge when every brand signs a famous face, so the winners will tie the partnership to operations, not just posts.
