What Chrono@Work B.V. does

Chrono@Work B.V. is a Dutch private limited company headquartered in Groningen, Netherlands, operating as a science-driven research, training, and consultancy firm specializing in chronobiology and sleep. Founded in 2016 as a partner company of the University of Groningen, the firm provides scientific knowledge, research project execution, consultancy, and training services across five core service lines: Research, Training, Consultancy, Knowledge dissemination, and Biomarker Analysis. Its core technology stack is grounded in clinical chronobiology methodologies, including ambulatory polysomnography (PSG), wrist-actigraphy, salivary dim-light melatonin onset (DLMO) analysis, melanopic photometric measurements, and light therapy protocols — enabling assessment of circadian phase, sleep-wake patterns, and the relationship between light exposure and sleep architecture under field conditions.

The firm serves four primary B2B segments — public authorities and government bodies, healthcare institutions and professionals, enterprises (particularly those with shift-work or 24/7 operations), and scientific/research institutions — alongside a nascent consumer segment. Named clients include Philips, Jeroen Bosch Hospital, GGZ Drenthe, Ambulancezorg Nederland, Honeywell, Medilux, and the Dutch Brain Foundation. Revenue is generated through bespoke professional services engagements: research projects, training workshops, and expert advisory on shift work optimization, workplace lighting, and chronotherapy. In May 2024, the firm launched Sleep in Sync, a consumer-facing coaching and melatonin analysis service marking its first subscription-style offering, and is developing the Good Night App under a European-funded PCH Ecosystem collaboration with University Medical Center Groningen.

The firm has a small team of 6 employees, is led by CEO Marijke Gordijn (Vice President of the Society for Light Treatment and Biological Rhythms), and has produced 22+ peer-reviewed scientific publications. Funding has come exclusively from regional and European public grants (SNN €25,000 in 2018, EFRO VIA grant in 2020, UMCG PCH Ecosystem funding in 2021), with no disclosed venture capital or institutional investment. The company maintains active media presence with 22+ TV/radio appearances and 67+ news items, positioning its CEO as a public authority on sleep and chronobiology in the Dutch market.
