The challenge
StemCell HOST is a clinic dedicated to stem cell treatments for children with autism. Their patients come from all over the world — families traveling from the United States, Canada, Europe, and Latin America seeking an alternative for their children.
Before Hillflare, they tried Google Ads. Google rejected them — the platform's policies restrict advertising of stem cell treatments. They worked with another marketing agency that couldn't offer solutions.
With no results, not knowing what to do, and with high-value treatments (each therapy costs thousands of dollars), StemCell HOST started working with Hillflare in December 2019.
What Hillflare did
Compliant Facebook Ads
We designed campaigns that comply with Facebook's policies for medical treatments. Focus on real family stories, not medical promises. Educational content that builds trust without violating guidelines.
Video Success Stories
Active production and promotion of testimonials from families worldwide. Videos of parents sharing their children's progress after treatment. The most effective content across all campaigns.
Intent-Based Retargeting
Segmented retargeting audiences: those who watched complete videos, those who visited the pricing page, those who filled out forms without submitting. Each audience receives different messaging.
International Expansion — Spain
After stabilizing results in Mexico and the US, we expanded campaigns to the Spanish market. Creative adaptation, landing pages in European Spanish, and targeting by major cities.
Closed-Therapy Optimization
We don't optimize for leads — we optimize for therapies actually completed. If a campaign generates 50 leads but 0 therapies, it gets cut. If another generates 10 leads and 3 therapies, it gets scaled.
High-Ticket Lead Nurturing
Specialized follow-up sequences for families considering the trip. Information about logistics, accommodation, medical process. No-show reduction for high-value treatments.

Sometimes you have good results and think that's the ceiling of your business, until you work with people with the level of expertise that Hillflare has.
