This platform facilitates encrypted communication, enabling medical teams to share patient data, discuss complex cases, and coordinate care efficiently within a compliant environment.

Siilo is a healthcare technology company that developed a secure messaging app for medical professionals to coordinate patient care, discuss cases, and share expertise compliantly.[1][3][4] Formerly independent and founded in 2015 in Amsterdam, Netherlands, it was acquired by Doctolib in March 2023 and rebranded as Doctolib Siilo, raising $15.67M total funding prior to acquisition.[1][4] The platform serves healthcare professionals and organizations across Europe, solving fragmented communication challenges in healthcare with encrypted chat, voice/video calling, and network tools; it grew to over 250,000 members as Europe's largest medical network, now integrated into Doctolib's 2,800-employee operation across 30+ cities.[1][4]
Post-acquisition, Doctolib Siilo enhances Doctolib's Benelux expansion, prioritizing data security and workflow efficiency for hospitals like St George's University NHS and East Lancashire Hospitals NHS Trust.[1][4]
Siilo was founded in 2016 by Arvind Rao and Joost Bruggeman in Amsterdam, Netherlands, to address coordination hurdles for healthcare professionals in patient care.[1][4] Rao and Bruggeman, drawing from industry insights, built it as a secure alternative to insecure messaging, starting with encrypted chats and evolving into a full collaboration platform with voice/video and organizational tools.[1][3][4] Early traction came from rapid adoption in Europe, securing €4.5M in funding led by EQT Ventures to target UK and Germany growth, reaching 250,000+ users and partnerships with major NHS hospitals.[1][4] The pivotal 2023 acquisition by Doctolib—founded in 2013 by Stanislas Niox-Chateau and others—merged strengths, rebranding to align with Doctolib's vision for connected healthcare.[1]

Siilo rides the digital health communication trend, accelerating post-COVID demand for secure, efficient tools amid clinician burnout and siloed care.[1][4] Timing aligns with Europe's GDPR-strict regs and telehealth boom, where fragmented messaging risks data breaches; market forces like hospital digitalization and cross-border care favor compliant platforms.[1][3] As part of Doctolib—the dominant European health tech player—Siilo influences the ecosystem by scaling networks, improving care coordination, and enabling knowledge exchange, potentially standardizing secure comms across borders.[1]
Doctolib Siilo will likely deepen Benelux integration, expanding AI-driven features for case triage and analytics to boost adoption beyond 250k users.[1] Trends like unified health platforms and regulatory pushes for interoperability will propel growth, evolving its role from niche messenger to core workflow hub in Doctolib's empire. This positions it to redefine connected care, building on its secure foundation for sustained ecosystem impact.
