Seph Fontane Pennock has successfully exited an eight‑figure venture, creating platforms that serve tens of millions and co‑founding software adopted by therapists and coaches worldwide. His latest project, Regenerated.com, emerged from a personal need rather than a market opportunity.
His journey into regenerative medicine began in an Amsterdam apartment he purchased and soon regretted. “I couldn’t sleep there,” he recalls. “I was constantly dehydrated, drinking water all the time, and I felt this persistent stress in my body that I couldn’t explain.” It took a long time before anyone gave him an answer. The apartment had toxic mold. Biotoxin exposure triggered a cascade: systemic inflammation, gut dysfunction, mitochondrial damage, autoimmune flare‑ups. His nervous system grew so sensitized that residential environments stopped feeling safe. For a period, hotel rooms were the only places his body would settle. He wasn’t choosing to travel. He had no other option.
“At one point I was frankly suicidal,” he says. “When you cannot sleep, cannot think clearly, cannot feel safe in your own home, and no doctor can explain the cause, it shatters you.”
Over the following years, Seph Fontane Pennock visited more than fifteen regenerative‑health clinics across several countries. His treatment list reads like a field guide to the edges of modern medicine: hyperbaric oxygen therapy, stem cells, exosomes, ketamine, stellate ganglion blocks, chelation, fecal microbiota transplants. A surgery in Germany went wrong, leading to a wound infection and three courses of antibiotics. “For a long time after that,” he says, “I just didn’t feel the same anymore.”
What he discovered at every stop was not only his own suffering but also a complete absence of any independent resource for patients trying to determine who to trust. Seph Fontane Pennock watched clinics with unverifiable credentials market themselves confidently. He saw IV bars offering serious treatments without any physician nearby. He found providers on federal exclusion lists, flagged by the government, still open and taking patients. “The average person searching for a stem cell clinic or an HBOT provider has no way to tell the difference between a credible practice and one that’s just good at marketing,” he says. “That gap between how these clinics present themselves and what’s actually behind the curtain is enormous. And there’s no one checking.”
So he began to investigate.

Regenerated.com launched in May 2026 with more than 8,000 vetted clinic listings across all fifty U.S. states, filtered from an initial pool of over 20,000. Each listing undergoes a five‑point assessment of credentials, evidence, transparency, outcomes, and integrity. Providers are verified against the federal National Provider Identifier registry and the Office of Inspector General exclusion list. Physician oversight is explicitly flagged. Medical spas and wellness centers are excluded.
Fontane Pennock’s track record lends credibility to the ambition. His prior platform, PositivePsychology.com, grew from a blog he launched when the internet lacked science‑based wellbeing content into a resource serving 19 million users, accredited by the American Psychological Association and sold to Eden Capital in New York in May 2023 for an eight‑figure sum. ‘Two small‑town boys from the Netherlands who started a blog in a Facebook group,’ he says of himself and co‑founder Hugo Alberts, ‘and now we’re selling a business to a PE firm in Manhattan.’ His co‑founded platform Quenza continues to serve therapists and coaches worldwide.
The directory serves as the foundation, not the ceiling. Two unannounced services are in development. Regenerated Protocols, slated for later this year, will provide patients direct access to prescribed peptide therapy, hormone optimization, and post‑procedure aftercare via licensed physicians. Regenerated Labs will enable patients to order diagnostic panels, have results reviewed by a provider, and receive a personalized protocol based on those results. The medical infrastructure is outsourced; Fontane Pennock’s platform owns the patient relationship and the overall experience. “The directory helps you find a clinic,” he says. “Protocols and Labs give you the tools to take control of your own health between visits.”
His target market includes roughly 50 million Americans living with autoimmune disease, plus millions more navigating conditions that conventional medicine often misses — such as mold illness, long COVID, hormonal dysfunction, and chronic fatigue. The regenerative‑medicine market is currently around $16 billion and growing at over 15 percent annually, yet patients have had almost nowhere independent to turn.
Every decision Seph Fontane Pennock makes about Regenerated.com passes through the same filter: Would this have helped the version of himself who was sick, confused, and searching across continents without a map?
He is ensuring that the next patient has it.
