Profile bio
About Mathilde Halle
I am an attorney admitted to the NY and Paris (France) bars with 15 years of experience in tech transactions and privacy in an international context. After working for international law firms for 10 years, I joined a the SaaS start-up world as in-house counsel, becoming a trusted resource supporting the growth of the business on a daily basis. I currently lead and manage OneStream's commercial transactions team for North America, which exposes me to the most significant deals, complex contractual negotiations, intricate privacy and AI questions, and strategic projects with the company's senior leadership. From a substantive perspective, my practice focuses on contracts, technology/SaaS, licensing, privacy/security, AI, and telecom legal issues (transactional and regulatory) in the U.S. and EMEA. I support business and operational teams in successfully structuring and implementing their projects, closing deals and reaching their goals. I thrive working in an entrepreneurial environment with driven and kind colleagues and generally love challenges of all sorts, including and out of my comfort zone. Since I started my career, I have been involved in significant pro bono projects in Africa. I have advised several NGOs on human rights issues, and I have experience providing legal drafting and negotiation training at local law schools. Finally, I regularly publish articles and blog posts on cutting-edge legal topics, in English and in French, updating clients, contacts, and the wider legal community on changes relevant to their operations. I also have been collaborating on a successful podcast on innovation and the law for INTA, Brand&New, for four years, which leads me to investigate cutting-edge topics at the crossroads of law, business, and technology. Also, because it seems that I cannot stop taking exams, I recently passed the CIPP/E, CIPP/US, and CIPP/Canada privacy certifications with the IAPP and intends on taking the AIGP in the coming months. Last, I am fluent in English, French, and Spanish.I am always eager to meet enthusiastic people and get involved in innovative projects, whether or not related to my current practice. Please feel free to contact me. My email is halle.mathilde@gmail.com. Thanks for checking out my profile!
