What Siteworks does

Siteworks GmbH is a privately held German clinical research site network (Site-Network) that conducts Phase Ib through IV clinical trials across six sites in Germany — Hannover (headquarters), Karlsruhe, Bochum (two locations), Schleswig, and Goslar. The company positions itself as the operational intermediary between pharmaceutical sponsors and CROs on one side and practicing physicians, clinics, and patients on the other, framing its role as the "binding link" that enables physicians without research infrastructure to participate in clinical studies while delivering GCP-compliant trial execution to sponsors. Therapeutic areas covered include Internal Medicine, General Medicine, Cardiology, Pulmonology, Sleep Medicine, Allergology, Dermatology, Neurology, Psychiatry, Gynecology, Gastroenterology, and Vaccine/Covid-19 studies.

The core product is the multi-site network itself, supported by GCP-aligned quality management systems, a dedicated Study Portal (siteworks-studien.de) with a clinical trials registry and patient registration flow, and an organizational infrastructure that provides administrative, regulatory, staffing, and quality management support to affiliated physician practices. Technology stack is conventional: Google Analytics and Google Fonts integrations, GDPR/DSGVO-compliant data handling with an external data protection officer, and standard web infrastructure rather than proprietary software. The company markets through a trilingual corporate website, the study portal, and direct outreach channels segmented by stakeholder (feasibility@, kooperation@, jobs@, datenschutz@).

The revenue model is professional services: contract-based clinical trial execution for pharmaceutical sponsors and CROs, with pricing tied to study scope, duration, and complexity and not publicly disclosed. Customers are enterprise (pharmaceutical sponsors and CROs) while physicians/clinics and patients are network participants. The company is led by co-Managing Directors Carolin Linden and Christine Oltmann, registered as a GmbH in Hannover (HRB 226931, VAT-ID DE331366615), with 11–50 employees and no disclosed funding, parent company, or revenue figures.
