Sword Health Case Study
Sword Health is a digital physical therapy platform on a mission to free 2 billion people from pain — without surgery, without painkillers, from the comfort of home. With $450M raised and a global expansion on the horizon, the growth trajectory was set. But acquisition costs were unsustainable.
GrowthHit rebuilt the enrollment funnel, restructured paid media, and launched a segmented email program to make sure every dollar spent on growth came back with room to spare.

Lessons from helping Sword Health grow
Here's what the data showed us:
Fear converts. Hope doesn't — at least not first.
Every instinct in health marketing says lead with the positive. The transformation. The pain-free hike. The grandkids you can pick up again. Sword Health tested it both ways, across six independent experiments. Fear-based messaging won every time. "Stop taking painkillers to numb your pain" beat "Do what you love pain free." "Surgery is Scary" was the all-time top ad. The person searching for a pain solution isn't dreaming yet — they're scared. Meet them there first. The aspiration comes after the trust is built.
Generic landing pages are a conversion tax on your ad spend.
Every click Sword Health bought went to a page that didn't fully acknowledge who it was talking to. A PepsiCo employee landing on a Sword Health page that barely mentioned PepsiCo had no immediate proof that this was their benefit. One landing page redesign — with company branding, employee-specific messaging, and relevant testimonials — produced a 1,846% lift in eligibility checks. That's not a marginal improvement. That's the difference between an ad program that works and one that burns budget.
Enrollment is a segmentation problem, not a messaging problem.
The instinct when enrollment rates are low is to rewrite the copy. The real fix is to ask: who are we sending this to, and is this the right message for them? GrowthHit segmented Sword Health's email program by worker type — frontline vs. corporate, blue collar vs. white collar — because these populations have fundamentally different healthcare relationships, schedules, and trust thresholds. Sending the right message to the right segment, not a better message to everyone, is what moves enrollment rates.
