We secure the digital transactions of European citizens
Letxbe is building the reference sovereign AI agent for the back-office of European financial institutions.
Vision
To be the reference sovereign AI agent for the back-office of banking and insurance services in the European Union.
Mission
Accelerate and simplify digital transactions without compromising data security and privacy.
Our story
Letxbe was founded in July 2022 from the meeting between Pierre Magrangeas (École Centrale Paris, 10 years of AI entrepreneurship) and Fabio Coppini (PhD in Mathematics, 10 years of R&D).
Their collaboration was born from shared consulting missions, where they identified a pressing need: financial institutions were drowning under complex document flows, processed manually, with growing non-compliance risks.
With complementary skills — entrepreneurship and applied AI on one side, mathematical research and algorithms on the other — they founded Letxbe to create a sovereign AI agent, capable of understanding and processing regulated transactions with expert precision and machine speed.
