A New Generation of Longevity Clinics in Southeast Europe

The world is shifting from reactive sick care to proactive health care, and we believe that shift is only just beginning.

Public awareness is rising. Health data is more accessible than ever. And the science of aging is no longer confined to labs or luxury retreats.

But while the category is booming in the US, much of Southeast Europe still lacks access to comprehensive longevity care. Most existing providers focus only on diagnostics or offer generic wellness services that aren’t built to retain patients or drive long-term results.

Blue Longevity Clinic is changing that.

Founded by serial healthcare entrepreneur Ilian Grigorov, the company is launching a new generation of longevity clinics in Southeast Europe, with locations in Athens, Istanbul, and Sofia opening this September. Inspired by the longevity principles observed in Blue Zones, the model combines advanced diagnostics, a digital app for behavior change, and regenerative therapies, all under one roof.

The Right Team at the Right Time

The most important part of any early-stage company is the team. Especially in a space as complex as healthcare, execution matters a lot, and Blue Longevity Clinic’s team knows how to deliver.

Ilian Grigorov is a longtime friend of our Health partner Valeri, a long-standing member of Eleven’s network, and one of the most accomplished healthcare entrepreneurs in the region. He founded CityClinic and scaled it into a leading healthcare provider, ultimately selling the business to Acibadem in 2016. Following that, he launched Blocks Health, a state-of-the-art rehabilitation facility with branches in Bulgaria and Greece. Now he’s back with a bigger vision, building the company he believes the region needs most.

Ilian’s joined by another serial entrepreneur Blagoy Palev who was Ilian’s co-founder in Blocks Health as well. The two have worked side by side for years, successfully scaling and exiting their previous venture. Another key member of the team is Dr. George Vissarakis, a rehabilitation expert with two decades of clinical leadership across Greece and the UK. 

Blue Longevity is one of the first companies locally to combine medical credibility, product depth, and entrepreneurial experience into a scalable model.

A Rising Wave and a Local Gap

We’ve had a front-row seat to the global shift from reactive sick care to proactive health care. Influencers like Peter Attia, Andrew Huberman, and David Sinclair have helped push longevity into the mainstream. In the US, there are already 800+ longevity clinics and counting.

That wave is coming to Southeast Europe next. The region’s growing middle class, rising medical tourism, and high healthcare spend create the perfect conditions for longevity clinics in Southeast Europe. But until now, most options have been exclusive, analog, and disconnected.

Blue Longevity is the opposite: integrated, tech-enabled, and built with retention in mind. From diagnostics to digital guidance to on-site therapies, it delivers a full journey, not just a one-off test.

What Makes It Different

Diagnostics Meet Behaviour Change

Blue Longevity Clinic is not a wellness spa with a blood test menu. It’s a comprehensive platform for personalized longevity medicine.

Here’s how it works:

  1. Functional diagnostics – including an elite blood panel, VO2 max test, genetic risk screening, gut microbiome analysis, DNA aging clocks, ECGs, physical assessments, and more. Patients walk away with a 360° health overview covering metabolic, cardiovascular, genetic, mental, and musculoskeletal systems. This data is analyzed by AI and reviewed by doctors to generate a detailed, actionable longevity report.
  2. Personalized longevity protocols – driven by an AI-powered engine that flags key biomarkers and translates diagnostics into tailored recommendations. Medical specialists oversee this process to ensure real-world relevance and safety.
  3. Digital support – the Blue Longevity App helps clients track their progress, build better habits, and stick to their plans. Built on the Fogg Behavior Model, a scientific method that helps people form habits by starting small, it integrates with wearables and medical devices, offering hyperpersonalized coaching that helps improve protocol adherence.
  4. On-site therapies – including Hyperbaric Oxygen Therapy, Cryotherapy, Infusion Therapy, IHHT (Interval Hypoxia-Hyperoxia), and Red Light Therapy. These interventions support and amplify lifestyle changes with a focus on key categories for improving a person’s biological age: 
    • Glucose Metabolism
    • Mitochondrial Function
    • Cardiovascular Health
    • Inflammation and Immune System Balance

The end goal is more than prevention. It’s transformation. A system that helps patients not only identify risk early but make meaningful changes that last.

Who It’s For

Built for Real People, Not Just Biohackers

Not everyone wants to live to 120. But most people want to feel better, longer.

Blue Longevity Clinic is built for anyone who feels like they could do more for their long-term health but doesn’t want to do it alone. Whether you’re feeling burned out, recovering from a health scare, or just tired of vague blood test results with no follow-up, Blue Longevity gives you a starting point and a structured way forward.

The Road Ahead

Blue Longevity Clinic is opening its first three locations in Athens, Istanbul, and Sofia this September. The €2M round, led by Eleven Ventures with participation from Sofia Angels Ventures and several angel investors, will fuel:

  • Final build-outs of clinical locations
  • Key hires in both clinical and non-clinical roles
  • Finalizing the equipment for therapy modules
  • Testing out go-to-market experiments

With the right capital, timing, and team in place, we believe Blue Longevity Clinic has the potential to become a category-defining company, not just in Bulgaria, Greece, or Turkey,  but across emerging markets where preventive health is overdue for reinvention.
