What RTsafe does
RTsafe is a privately held medical device company founded in 2014 and headquartered in Athens, Greece. According to its firmographic profile, the company developed, patented, and commercialized what it describes as the world's first FDA-cleared Personalized Care service in Radiation Oncology. Its offering targets the patient-specific quality assurance and dosimetry verification problem in radiotherapy — a clinically critical workflow at cancer treatment centers where personalized pre-treatment plan validation reduces misadministration risk. The company has 11–50 employees and operates within the image-guided radiation therapy market, which industry commentary projects will reach $2.48 billion by 2030 at a 4.4% CAGR, driven by AI integration, demand for non-invasive cancer therapies, and emerging-market accessibility.
The business model centers on selling or licensing patient-specific QA solutions to radiotherapy centers and cancer treatment providers, monetizing FDA-cleared clinical software/phantoms in a niche but high-safety-stakes segment of radiation oncology. Capital has been sourced primarily from Greek and European seed-stage backers: VentureFriends led two rounds (2017: $2.25M; 2019: $1.0M), with earlier support from The Hellenic Initiative ($250K, 2014), Envolve Entrepreneurship (incubator, 2014), MIT Enterprise Forum Greece ($10K, 2015), and undisclosed seed investors ($400K, 2016; $35K, 2015). Founder Evangelos Pappas serves as CEO; co-founder Nikos Stergiopoulos and Chief MR Technology Officer Thomas Maris round out the executive team, with the CTO role signaling MR-guided radiotherapy as a focus area.
The current operating state is materially uncertain. The firm's public website (rt-safe.com) currently displays only a "loading/verification" page with no accessible content. The last disclosed financing is March 2019, and the available sources contain no customer logos, pricing, partnership announcements, product roadmap updates, or revenue data. Whether the company remains commercially active, has pivoted, or is effectively dormant cannot be confirmed from the input data — a fact that materially constrains any forward-looking inference about the business.
