Sales - 2025
Septeo, a leading software publisher in France and Europe, announces the acquisition of Bylaw, a pioneering company and leader in artificial intelligence solutions for regulated professions. Bylaw was advised by Largillière Finance, which completed the transaction within a tight three-and-a-half-month timeline.
A strategic alliance in the fast-growing AI solutions market
Founded in 2019 by Adrien Aboudaram and Tuan Ardouin, Bylaw has developed a next-generation artificial intelligence solution that automates the processing of legal and financial documents. Integrated into business software, it enables documents to be analyzed in just seconds to extract, classify, and leverage information—a task that would normally require dozens of employees. Today, the Bylaw solution is used by 50% of France’s court-appointed administrators and by the largest notarial practices. With a team of 20 employees, 80% of whom are dedicated to R&D, Bylaw aims to become the benchmark in AI for regulated professions.”
Complementary expertise for a shared ambition
With this partnership, Septeo pursues a clear objective: to strengthen its position as a leading provider of software solutions for regulated professions by integrating cutting-edge artificial intelligence technologies at the core of its business tools. This strategic decision responds to the growing market demand for more efficient and intuitive solutions while anticipating future changes, allowing clients to stay ahead and supporting their digital transformation. For Bylaw, this alliance represents a unique opportunity to accelerate growth through Septeo’s client base and commercial reach, while maintaining significant autonomy over the development of its AI solutions. Joining Septeo’s cross-functional “Digital Services and Security” division, Bylaw is already contributing its AI capabilities to enhance the Notarial Act Drafting Software (iNot and Kivia). Its solutions will subsequently be deployed across other business software within the group for regulated professions (accountants, HR, hospitality, etc.), starting with legal professions.
For Adrien Aboudaram, Founder of Bylaw :
“We are very pleased to join the Septeo group. This partnership allows us to accelerate our deployment and focus on our core business: developing cutting-edge artificial intelligence solutions. By partnering with a key player in business software, we will be able to deploy our automation technologies at scale, directly within the business software already used by professionals, thereby multiplying their added value and the use of Artificial Intelligence within regulated professions. We would also like to thank the teams at Largillière Finance, who played a decisive role in the success of this transaction, delivering a smooth execution in an exceptionally short timeframe.”
For Hugues Galambrun, Founder and President of Septeo :
“Integrating Bylaw into our solutions is not just a technological choice, it is a strategic decision that reflects our commitment to deeply support our clients’ transformation. In a world where artificial intelligence is reshaping practices and accelerating changes across our industries, we aim to be a key driver of this shift, empowering regulated professions to focus on added value and consulting. With Bylaw, we are entering a new phase: simplifying everyday life, enhancing collective efficiency, and contributing to the digital and societal revolution we are currently experiencing.”
For Nathanaël Blanc, Associate Director at Largillière Finance :
“We are proud to have supported Adrien Aboudaram and Tuan Ardouin in this strategic transaction. The integration of Bylaw perfectly illustrates the convergence between business software publishers and specialized AI players. Within a demanding timeline, we were able to maximize our clients’ interests and provide them with an exceptional development outlook.”
With more than 40 employees, a strong international presence and nearly 30 operations in 2024, Largillière Finance confirms its leader position in small and midcap in France.
