About us

What We Do – Our Vision

Consocium – standing for “Consulting” and the Latin word socius = “Companion” – is the professional network of freelance management consultants. Our mission is to make Consulting 4.0 reality: Based on the principles of swarm intelligence, we sell and deliver projects in teams of the best experts.

Established in January 2016 by two alumni of leading strategy consulting firms, Consocium started based on feedback from various clients who appreciated our work but considered it too expensive. We would have been glad to deliver many of these projects as freelancers for a fraction of the rates and to the same quality standards. So the idea emerged to establish a network of only the best freelance consultants in order to make high-quality consulting affordable for our clients.

For our members, we are more than just another placement agent. With us, freelance consultants become part of a strong network, opening up opportunities to jointly develop topics, pitch projects and work together in teams – without abandoning their entrepreneurial freedom.
