Novisto acquires Minimum to expand carbon management and sustainability reporting platform

Montreal-based Novisto acquired London-based Minimum, a carbon management software provider, to integrate Minimum’s granular carbon intelligence into Novisto’s sustainability reporting platform. Founded in 2020, Minimum specializes in simplifying the collection, calculation, and reporting of corporate carbon footprints through its Carbon Atlas tool, which maps environmental inventories across large organizations. Novisto, which raised $27 million in 2025 to enhance its platform, aims to deliver a unified system of record for sustainability data, addressing regulatory demands like the EU’s CSRD, UK’s SRS, and California’s SB 253. The acquisition leverages Minimum’s flexible data ingestion capabilities, enabling Novisto to transform fragmented sustainability data into audit-ready carbon inventories with full traceability. Chris Winchurch, CEO of Minimum, emphasized the need for deep carbon data integration within broader ESG platforms, while Novisto’s CEO Charles Assaf framed the deal as a step toward providing enterprise-grade sustainability management akin to financial reporting standards.
