Nossa Data

Nossa Data is a London-headquartered software company that provides corporates with a platform for collecting, managing and disclosing environmental, social and governance (ESG) data. The product covers structured data collection workflows, governance protocols, audit trails, evidence controls and version history intended to support assurance and internal review, plus collaboration features such as mass-assigning of disclosures, custom user roles, approvals and status tracking across departments.

The platform supports and maps between major ESG and sustainability reporting frameworks, including ISSB (IFRS S1 and S2), CSRD/ESRS, CDP, EcoVadis, SASB, GRI, TCFD, MSCI ESG ratings and the Workforce Disclosure Initiative (WDI), with dynamic crosswalks so a company can generate aligned disclosures across multiple frameworks; custom internal frameworks can also be added to a customer account. Users can submit directly to standards such as CDP and EcoVadis and generate GRI or SASB indexes for annual reports. Additional capabilities include peer benchmarking, aggregated tracking of ESG rating agency scores, AI-based insights and recommendations, and integrations with ERP, HRIS and carbon accounting systems with import/export automation. Positioning emphasises UK and EU regulatory compliance.

Founding story

The company was started in March 2020, as the Covid-19 pandemic lockdowns began, by Julianne Flesher (CEO) and Irina Dumitrescu (CTO), who had repeatedly seen how burdensome ESG disclosure was for companies. The founders concluded that no existing tool adequately helped companies gather and report ESG information efficiently and set out to build one, assembling a team drawn from ESG, institutional investment, enterprise technology and start-ups.

Business model

Software-as-a-service sold to corporates, with demo requests as the entry point and an onboarding process; the platform is offered to public companies, private companies, investors and consultants, and pricing is not published on the site.

Software subscription sold to companies for ESG reporting and data management; specific pricing is not disclosed publicly.

Traction

The company states its software enabled all 170 WDI disclosing companies, including half of the FTSE 100 such as Unilever, Barclays, AstraZeneca and H&M, to submit their 2021 workforce data, generating thousands of pieces of product feedback. Publicly referenced clients include Vodafone, PensionBee, Imperial Brands and Accsys, whose ESG and reporting managers provide testimonials on the company website.
