Who we are

Semsoft is a French technology company founded in 2009 by François Paulus. Originally a spin-off from Orange Labs, it resulted from a decade of research in data fusion and artificial intelligence. In 2018, after several years of transforming Big Data into actionable insights across various business sectors, Semsoft focused on combating criminal activities at sea.
 
Lestr is the software solution developed by Semsoft to address illicit activities concealed under the guise of international trade, using maritime freight transport as a cover. Initially an HSBC project aimed at ensuring compliance with international sanctions and AML/CFT regulations while enhancing operational efficiency through the automation of time-consuming manual controls, Lestr is now utilised by financial institutions, commodity traders, and government authorities responsible for maritime security.
 
Based in Rennes, Brittany, a region historically linked to maritime trade. Semsoft chose the name "Lestr," which means “vessel” in the Breton language.

WHAT WE DO

We work daily to transform suspicious situations or confirmed cases of fraud and trafficking into risk indicators and effective controls to prevent and detect such activities.
 
To achieve this, we analyse all reported criminal and fraudulent practices to identify key elements that shed light on these issues. Additionally, we leverage our expertise in data fusion to collect and cross-check a wide array of data sources, enabling us to examine all facets of an international trade transaction.
 
Our value proposition is to serve as your one-stop solution for monitoring international trade operations and detecting illicit or suspicious activities. This customisable platform can be tailored to your specific data sources and risk management approach.
Lestr relies on a recognised technology of data fusion to revolutionise the way to prevent, detect and manage risks inherent to international trade.

Our vision

International trade is vital to the functioning of our societies. Unfortunately, it also has a dark side. The inability to physically track every container and accurately monitor each vessel makes international trade susceptible to illicit activities, including embargo circumvention, sanction violations, trade-based money laundering, and drug trafficking.

In this context, our objective is to collect, cross-check, and analyse data to examine all aspects of international trade transactions, detecting illicit or suspicious activities to safeguard international trade from illegal and harmful practices.

Our ambition is to become a leading player in the fight against crime disguised as international trade.

Clients & Partners

"The value added by the solution is in time saved. Since the time needed to perform controls is divided by five - reduced to 10 minutes, this is on top of the increased transparency for the customer."
