Sustainability management platform Novisto has announced the acquisition of Minimum, a London-based developer of carbon accounting software. The transaction is designed to incorporate Minimum’s specialised carbon tracking technology directly into Novisto’s existing enterprise suite, creating a unified system for environmental, social, and governance (ESG) data.
The move follows a shift in the regulatory landscape, with the implementation of mandates such as the EU’s Corporate Sustainability Reporting Directive (CSRD) and California’s SB 253. Industry analysts from Verdantix noted in June 2025 that the market is moving away from “point solutions” toward integrated suites that provide a centralised source of data for large enterprises.
Prior to the acquisition, the two companies maintained a partnership and shared several enterprise clients. The integration will allow users to manage automated carbon calculations, supplier engagement, and financial-grade reporting within a single interface. The expanded platform covers various global frameworks, including GRI, SASB, and TCFD, while offering tools for double materiality and climate risk modelling.
Eugene Brown, Senior Director of Sustainability at Synopsys, commented on the previous partnership: “Having partnered with both Novisto and Minimum for 2 years, we’ve experienced firsthand the distinct value each brings to our organization. The integration of their capabilities into a single platform will allow us to seamlessly automate our carbon accounting workloads, significantly reducing reporting friction and time spent on data collection.”
Company leadership indicated that the acquisition addresses a growing demand for rigorous, audit-ready sustainability data.
“Our mission has always been to bring financial-grade rigor to sustainability, giving the world’s largest organizations the confidence, structure, and accountability they’ve long relied on in finance,” said Charles Assaf, CEO and Co-Founder of Novisto. “By embedding Minimum’s specialized carbon technology, we are delivering a centralized system of record that allows enterprises to manage their climate impact and regulatory obligations.”
Chris Winchurch, CEO of Minimum, added: “Customers are looking for a unified way to manage their sustainability and carbon data without compromising on depth or rigor. We are thrilled to join forces with Novisto to deliver on this clear market need.”
