The people behind Capillary.io

Medical experience. Technical expertise. A shared purpose.

Capillary.io grew from a collaboration between Borja Gracia Tello, an internist who performs capillaroscopy regularly, and Eduardo Ramos Ibáñez, a software engineer specialized in artificial intelligence. We build tools that connect image capture, quantitative analysis, expert review and research data.

Dr. Borja Gracia Tello, MD, PhD

Dr. Borja del Carmelo Gracia Tello is an internist and academic director of the Systemic Autoimmune Diseases Unit at Hospital Clínico Universitario Lozano Blesa in Zaragoza, and Professor of Medicine at the University of Zaragoza. After his specialist training in Internal Medicine, he completed a research fellowship with Professor David Isenberg at University College London.

His clinical and research work focuses on systemic autoimmune diseases, microvascular involvement and systemic sclerosis. He has coordinated and participated in national and international research projects, and is co-author of CAPI-Score and CAPI-DETECT for quantitative videocapillaroscopy. His regular capillaroscopy practice helped shape the original idea for Capillary.io.

Borja also chairs the Scientific Advisory Board of the Capillaroscopy.com educational initiative.

Eduardo Ramos Ibáñez

Eduardo Ramos Ibáñez is a software engineer specialized in machine learning and deep learning, with a degree in Computer Engineering from the University of Zaragoza. As co-founder and CTO of Capillary.io, he leads the technical strategy and development of its capillaroscopy software.

He works closely with Borja and other clinical experts to turn capillaroscopy expertise into quantitative algorithms and practical software tools. Eduardo is co-author of peer-reviewed publications on comprehensive videocapillaroscopy, the clinical validation of automated image analysis, and the development of CAPI-Score and CAPI-DETECT.

Eduardo also chairs the Technical Advisory Board of Capillaroscopy.com, contributing his expertise in software engineering and machine learning to the educational initiative.

From a practical question to a research platform

Our work began in October 2017 with a question from Borja’s daily practice: could software help make capillary counting, classification and measurement more consistent and less time-consuming? Eduardo began developing prototypes, while Borja reviewed and annotated images to connect the algorithms with capillaroscopy expertise.

Capillary.io was released publicly in 2020. Since then, the work has grown into image capture, automated measurements, study review, research reports, exports and collaboration, supported by peer-reviewed research and close contact with healthcare professionals.

Today, researchers can choose Cloud, Desktop Research or a complete Research System. We continue to combine medical and technical experience when developing software, testing capillaroscopes and preparing compatible packages.
