42,000 tickets for one New York event. 15,000 gym affiliates. $0 spent on influencers. HYROX CGO Douglas Gremmen joins Kyriakos, CEO of Terra API , at the Connected Health Summit in Stanford to talk through what actually drove that — and what didn't work.
The US was their first market outside Germany and their hardest. Three years of losses. A single Lance Armstrong weekend changed the momentum — not because they paid him, but because he just turned up. The gym affiliate program started as inbounds with no structure; it's now the foundation of a bet to reach 100 million people. The CrossFit comparison gets a real answer, not a PR one.
But the most interesting parts are the early decisions: rejecting the $2 race t-shirt, the photo package that created the organic flywheel, and a simple principle — invest in the event experience and don't run paid marketing.
