Two proven founders join the agentic tax compliance leader to accelerate AI innovation and solidify a data foundation for 100,000+ customers
ATLANTA, GA, November 11, 2026 – Sovos, the agentic tax compliance company, today announced the appointments of Yann Ravel-Sibillot as Chief AI Officer and Yoni Lavi as Chief Data Officer. Both executives are founders with deep technical and operating experience and will help shape how Sovos applies AI and data across its Agentic Tax Compliance Platform. As Sovos continues to redefine tax compliance as a catalyst for growth, its Agentic Tax Compliance Platform enables companies to manage tax obligations worldwide from one source.
The appointments follow Sovos’ acquisitions of Blue dot in September and Flowie in October of 2026. Together, the two companies bring Sovos production AI models, autonomous finance and procurement agents, and a data science team with nearly a decade of enterprise machine learning experience. Yann and Yoni will lead the effort to integrate that technology across the platform, including the Sovos Graph, which maps the connections between business processes, systems, data sources, and the compliance rules that govern every transaction.
“We have an aggressive roadmap of AI innovation that will reshape our industry and solve the problems our customers face every day. We are committed to delivering the highest value products to our customers and these new roles are another step in that journey,” said Gregg Spratto, President, Sovos. “Yann and Yoni are founders who have built and shipped products in the real world. Yann has a rare ability to turn emerging AI into solutions customers can trust, and Yoni has a track record of building scalable data architecture, along with a legal background that suits our regulated environment. I can’t think of a better pair of executives to lead these key functions.”
As Chief AI Officer, Yann leads Sovos’ AI strategy, applying AI across the platform with a focus on responsible, secure, and practical adoption. An engineer and founder, he co-founded Flowie and served as its CEO from incorporation where the company’s AI-native agents ran finance and procurement processes end-to-end, including accounts payable, procure-to-pay, contracts, invoicing, and collections, on top of virtually any ERP system. His career also includes roles at Midnight Trains, Sunday, Big Mamma and other technology companies.
“Compliance is a domain where AI has to be accurate, secure, and explainable, or it isn’t useful,” said Ravel-Sibillot. “I’m excited to build on what Sovos has already established and put AI to work so customers can stay compliant while building efficiencies of scale across their tax and finance departments.”
As Chief Data Officer, Yoni leads Sovos’ data and AI strategy, turning data into a durable advantage for customers. He has 20 years of experience delivering enterprise software and SaaS products and managing R&D groups in both start-ups and large enterprises. Most recently he was Co-CEO of Blue dot, the Tel Aviv-based AI VAT intelligence and recovery platform, where he led company strategy and the development of its software. Earlier in his career, he co-founded and led a startup that sold Quality Experience solutions to global telecom providers. He holds a law degree from Tel Aviv University, a background that complements his work in the regulated world of tax compliance.
“Sovos sits on one of the most valuable regulatory and transactional data sets in the world,” said Lavi. “My goal is to turn that data into a lasting advantage for customers, with the quality, governance, and architecture that regulated industries demand.”
