Twenty years on the business side of live entertainment
Capacity is a consulting and software company for the live entertainment industry. We work with promoters, venues, and artist teams—people who have a clear vision and need expert-level execution.
Founder
John Harper
John Harper has spent two decades in live entertainment—as a promoter, an operator, and eventually as COO of EMC Presents, Michael Cohl's partnership with Eventim. He's worked on tours for David Gilmour, Genesis, The Rolling Stones, and The Pink Floyd Exhibition, among others. Before EMC, he held leadership roles at S2BN Entertainment, overseeing touring Broadway productions and large-scale concert events.
He founded Capacity because the industry he loves still runs on instinct and improvisation. There's room for better tools, clearer thinking, and partners who've already learned the hard lessons.

Years of Experience
Mission
We exist to make live entertainment operations more manageable—through consulting that draws on real experience, and software built for how this industry actually works.
Values
Attention
The details that seem small rarely are. We notice them.
Usefulness
We'd rather build something that works than something that impresses.
Candor
Clear communication, even when the news isn't good.
Taste
Knowing when something is right—and having the patience to get there.
Team
Capacity is a small firm by design. John works with a trusted network of specialists—people he's collaborated with for years across marketing, ticketing, production, legal, and sponsorship. We build each team around the project—bringing in exactly the expertise it needs, nothing more.
