The marketplace is available in 5 different countries with more than 5.000 actively bidding workshops.

Even before I was hired as the first employee, I helped the two founders (Stefan Avivson, Jonas Bruhn) with the pitch to our first investor (Janusz M. Sowadski).

The pitch was successful and I started building a team when the investment came in. After this, a number of investors joined, along with prominent members on our board (Morten Lund).

We built an intelligent e-mail parsing system for the shipping industry. The system could identify vessel and cargo position information, structure it and make it available via a intuitive interface.

Among the features were: Spam-detection, extrapolation of missing information, ability to handle typos, merging of duplicate information (even when info was missing), and it did all of this while also being able to handle almost any type of information structure in the emails.

Besides website, parsers, huge globally available databases etc., we also built a Microsoft Outlook Server plugin, which could label and extract information from incoming emails in near-realtime, on the customers own mailserver.
