Blue Longevity Clinic, a longevity medicine service provider, has secured €2M in funding to expand its operations in Southeast Europe. 

The round was led by Bulgaria-based Eleven Ventures, with participation from Sofia Angels Ventures and several family offices.

“The transition from reactive sick care to proactive health care is no longer a trend; it’s a global shift,” says Valeri Petrov, Partner at Eleven Ventures. “We’ve been closely tracking this category and believe the SEE region has the potential to become a key hub for medical and longevity tourism.”

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

Capital utilisation

Blue Longevity Clinic will use the funds to support its expansion in Southeast Europe. The company plans to open clinics in Athens, Istanbul, and Sofia in September, supported by in-house digital technology and diagnostic protocols. 

The funding will be used for clinic build-outs, completion of the therapy protocol stack, medical team expansion, and further development of its app and AI diagnostics engine to scale and personalise client services.

Milen Ivanov, Managing Partner at Sofia Angels Ventures, says, “Longevity is becoming the new frontier of healthcare – no longer a privilege reserved for eccentric biohackers, reclusive yogis, or billionaires. The science is already advancing at scale, and this will become a trillion-euro industry that helps millions live longer, healthier lives.”

“We believe in BL’s team and their ability to execute on their next healthcare venture, especially given the ripe timing for this mission.”

Promoting holistic well-being and longevity

Interest in preventive health and longevity has increased in recent years, driven by figures such as Dr. Peter Attia, David Sinclair, and Peter Diamandis. However, Blue Longevity Clinic reports in a statment that access to advanced diagnostic tools and treatment protocols has mostly been limited to high-net-worth individuals through physician-led clinics.

In Southeast Europe, longevity medicine remains underdeveloped, as it requires care models beyond the scope of traditional hospitals. This is where Blue Longevity Clinic looks to make a difference.

Founded by healthcare entrepreneur Ilian Grigorov, Blue Longevity Clinic seeks to make longevity medicine available to the emerging upper-middle class in the region, where out-of-pocket health spending is among the highest in Europe.

The clinic uses a fully integrated model combining in-person diagnostics, therapy programmes, and a digital app that supports behaviour change through microhabits.

The approach is focused on extending healthspan by identifying early changes in key systems like metabolism, brain function, the gut microbiome, and genetic markers. Clients receive physician-led health plans, supported by therapies such as Hyperbaric Oxygen Therapy, Cryotherapy, and Red Light Therapy. AI tools help interpret biomarkers and generate ongoing reports to guide progress. 

The clinic’s model offers continuous, personalised care aimed at delaying age-related decline and promoting long-term health.

Founder and CEO, Ilian Grigorov, says, “We’re building a new kind of health centre – one that people don’t just visit once a year, but one that becomes part of their lifestyle. Longevity is not a single test or therapy – it’s a journey.”

“Our goal is to be the first truly integrated and accessible preventive health platform in the region and one of the global leaders in providing longevity medicine services.”

Besides Ilian Grigorov, the company’s founding team includes Blagoy Palev, a former banker and co-founder of Blocks Health, and Dr. George Vissarakis, an expert in rehabilitation medicine and former director at Filoktitis Centre, Greece.
