Carstensen founded Fluxcode together with his former colleague, Rene Petton. The two met when they were working as software developers at the IT department of a medium-sized German tobacco products manufacturer.
“In general, we always tried to develop all production-relevant software for our former employer ourselves, particularly because a medium-sized enterprise can’t be handled according to the book and because history has shown that there are various special cases for which standard solutions would have become difficult,” Carstensen explains.
At that time, in 2016, the only T&T solution available for tobacco products was Codentify, a system developed by Philip Morris International and licensed to BAT, Imperial Tobacco Group and Japan Tobacco International. Today the product is marketed by Inexto. “There were no other providers,” says Carstensen. “Since the Codentify solution would also have been very cost intensive, we decided to develop the required software ourselves. With a project scope like TPD2, this was of course a complex endeavor. After we had completed our software solution and it became known within the tobacco industry that we had a functioning alternative to Codentify, we were approached by several smaller and mid-sized companies who acquired the solution we had then, which was called Red Carpet.”
As T&T gained importance, Carstensen and Petton decided to take their software to a broader, more professional level, and in 2020, they established Fluxcode. The Red Carpet software was resigned to history. In its place, Carstensen and his team developed a completely new solution in such a way that it can also be used to track products in other sectors. The company is already negotiating with manufacturers of drinks and tires.
Fluxcode developed the Fluxcode Suite, which is independent from the tobacco industry and divided into five core modules—one for ordering and downloading of the UI, one to create a globally unique identifier with included additional customer information, one to provide the correct UI to the production line printers, one to connect to the aggregation system and one for sending previously elaborately processed data to a repository. Modules can be purchased individually, depending on the requirements of the customer. Security against piracy is provided by encryption of the most important Fluxcode Suite codes, which users can only access by deploying a license key to unlock them.
Fluxcode also provides storage for the considerable amount of data generated, says Carstensen. “Many of our competitors rely on cloud hosting of the database. This means that the track-and- trace data of a manufacturer are being stored on the server of a service provider, to which the manufacturer himself potentially has no access. He will be able to retrieve a part of the data through various sighting processes but won’t have administrative sovereignty over the data. We don’t think that this is very practicable, as from our point of view, the data belong to the customer.”
Therefore, Fluxcode offers data storage on the manufacturer’s server. “This goes down well with our customers,” says Carstensen. “We have optimized the amount of data so that a small enterprise can produce several years with our software, and its data storage will remain in the low double-digit gigabyte zone.”
The company supplies only the software part of the track-and-trace system, but it has long-term partners from the respective hardware areas, including aggregation systems, printer manufacturers or external repositories. “At the request of the customer, there is also the option that one party acts as the general contractor,” says Carstensen. “This way, the customer has only one contact person and one contracting party without having to negotiate with each provider individually.”
