Doctena, a mobile appointment booking service based in Luxembourg, has raised $5 million (4.6 million euros) from undisclosed investors in a mix of equity and debt, according to TechCrunch. The company is positioning to be a ZocDoc for Europe.

Doctena helps patients book appointments with doctors in their region. Currently the service is live in cities across Belgium, Luxembourg, and the Netherlands. Patients can find a doctor by choosing a specialty, like allergist, cardiologist, dermatologist, or dentist, then specifying their location, and, finally, indicating their preferred language. 

Doctors on the platform speak more than 25 languages, including Albanian, Arabic, Chinese, English, Polish, and Russian. The company has also created a doctor-facing service that helps clinicians manage their patient schedule. 

Doctena will use the funds to expand its offering into other locations. Its first will be Switzerland.

Two other Europe-based appointment booking services made news earlier this year.

In October, French doctor booking startup DoctoLib raised $20 million (18 million euros) to expand its platform out to the rest of Europe. At the time DoctoLib's software-as-a-service offering served 5,000 doctors and 100 clinics across 80 specialties and served 2 million patients per month.

And in May, Warsaw, Poland-based DocPlanner, which offers a service that helps consumers find and book appointments with providers, raised $10 million. DocPlanner is available in 25 countries, including markets in Europe, South America, and Asia. It is available in 16 different languages. At the time of the funding, the service had more than 7 million monthly users and appointment booking available with more than 1.4 million doctors and dentists.

Last year, Paris-based KelDoc, another doctor appointment booking app, raised $1.4 million (1 million euros). Keldoc said it planned to use these funds to expand across major cities in Europe.
