Key Results
100+ creator partnerships built from zero — Natalie Jill, Olympic medalists, CrossFit athletes
Influencer engine became the brand’s primary acquisition channel
Repeatable creator pipeline spanning fitness, wellness, and outdoor lifestyle verticals
01, The Challenge
What the brand needed.
Launch and scale social for an outdoor fitness product with no existing influencer relationships, no creator pipeline, and a product category most people had never heard of. Build awareness from scratch in a market dominated by Peloton, Mirror, and gym culture.
02, The Approach
What Fifty & Five did.
Built a full influencer engine from the ground up. Identified, pitched, and closed 100+ creator partnerships across fitness, wellness, and outdoor lifestyle verticals. Landed Natalie Jill, Olympic medalists, and CrossFit athletes as organic ambassadors. Created a content system that turned every creator partnership into reusable social assets—workout clips, testimonials, unboxings—that fed the organic feed for months after each deal closed.

03, The Outcome
What actually happened.
Scaled from zero influencer relationships to 100+ active creator partnerships. Built a repeatable creator pipeline that became the brand’s primary acquisition channel. Proved that influencer marketing works for niche fitness products when you match the creator to the community, not just the follower count.
“Professional, organized, creative, smart, and consistently positive energy, which really matters when working with an agency. Thankful to have found this team.”
The hardest part of this category is explanation. A product nobody has seen before has to be understood before it can be wanted, and a static image does not do that job. Meanwhile the fitness conversation was owned by connected indoor equipment and gym culture, both of which had enormous budgets and an audience that already knew what it was buying.
There was also nothing to start from. No creator relationships, no pipeline, no roster of athletes who had ever touched the product, and no reference campaigns in the category to borrow structure from. Building an influencer program under those conditions is a sales job before it is a marketing job, and it fails outright if the outreach is generic.
Outdoor fitness content depends on weather and location, which makes production schedules unpredictable
A considered purchase means creator content has to teach, not simply endorse
Follower count is the wrong filter when the buyer is a specific kind of athlete
How the creator engine was built and run
The engine ran on matching, not on reach. Every partnership started by identifying creators whose community would plausibly ride the thing, then pitching them on the product rather than on a fee schedule. That is slower per deal, and it is the reason the roster ended up including Natalie Jill, Olympic medalists, and CrossFit athletes as organic ambassadors instead of paid placements that read as ads.
Identify creators by community fit across fitness, wellness, and outdoor lifestyle, then pitch and close
Brief each creator on what to demonstrate, so the footage explains the product
Harvest every deal for reusable assets: workout clips, testimonials, unboxings
Feed those assets back into the organic calendar for months after the partnership ends
That last step is what turned a hundred separate deals into a system. Content from closed partnerships kept working long after the deal itself was done, which is why the program became the primary acquisition channel rather than a line item that had to be refilled every quarter. Fifty & Five still builds creator programs this way for niche products, because matching a creator to a community beats buying follower count whenever a buyer has to understand something before purchasing it.

More than one hundred active creator partnerships, all built from a starting point of zero existing influencer relationships.

Most agency relationships start with a pitch deck. Ours starts with a conversation. No proposals until we know it’s a fit.
