The Persefoni Platform enables organizations and institutional investors to measure their carbon footprint MoreLess

Persefoni is a startup that operates in the environmental, social, and governance (ESG) technology market, specifically focusing on carbon accounting. The company has developed a platform that allows businesses to manage their emissions data with the same level of accuracy, transparency, and control as their financial data. This is particularly important in today's business environment where companies are under increasing pressure to disclose their carbon footprints and demonstrate their commitment to sustainability.

Persefoni's platform turns existing business data into an accurate carbon footprint, using a calculation engine that aligns with the Greenhouse Gas Protocol (GHGP) and the Partnership for Carbon Accounting Financials (PCAF). This means it takes into account all types of emissions, from direct emissions produced by a company's own operations (scope 1) to indirect emissions from both purchased electricity (scope 2) and other sources in the company's value chain (scope 3).

The platform also features a Carbon Activity Ledger, which provides a detailed record of a company's emissions, helping to minimize climate disclosure risks and meet regulatory requirements. This ledger can be scaled to match a business's growth and changing needs.

Persefoni's business model involves partnering with consulting, technology, and standard-setting firms to provide comprehensive solutions for businesses on their journey to carbon neutrality. The platform can integrate with other ESG reporting and key performance indicator (KPI) tools, such as Novata, to maintain visibility across portfolio companies.

In terms of revenue, Persefoni likely operates on a subscription-based model, charging businesses for access to its platform and services.
