Consulting and Strategy has been the core mission of Hessings & Harcourt since it has been created in 1849. Today, more and more people who want raise funds in order to launch their startups and to develop up their activities. However, they do not have the resources and contacts to do so.

Since 2018, Hessings & Harcourt spotted the issue and decided to create a tailor-made offer for these people who are looking to make a fundraising, an acquisition targeting or a company handover.
