Carbonfact serves 150+ customers including Columbia Sportswear, New Balance, and Carhartt, generating over $3 million in annual recurring revenue as demand for fashion sustainability software has grown sharply since 2023. Carbonfact's automated LCA platform solves the fundamental measurement challenge in fashion sustainability: a single garment's carbon footprint requires tracing emissions across fiber cultivation (cotton, wool, or synthetic manufacturing), yarn spinning, fabric weaving and dyeing, garment assembly (typically in multiple countries), and transportation — a supply chain emission calculation that involves 8-20 suppliers across different countries, each with different energy grid carbon intensities and process efficiency levels. Carbonfact's database of emissions factors (covering 10,000+ textile materials, processes, and transportation modes calibrated to specific country and facility type) enables automated LCA from a Bill of Materials (BOM) input — fashion teams enter product composition (60% cotton, 40% recycled polyester, dyed in Bangladesh, assembled in Vietnam) and receive a product carbon footprint within minutes rather than months of consultant-led manual LCA. The EU CSRD (Corporate Sustainability Reporting Directive) compliance module generates the required audit-trail documentation for Carbonfact's enterprise customers' annual sustainability reports. In 2025, Carbonfact competes in the fashion sustainability software, carbon accounting, and product LCA market with Higg Co (apparel industry sustainability standards, $22M raised), Sourcemap (supply chain transparency, $12M raised), and Planet FWD (food and apparel LCA, $10M raised) for fashion brand ESG software adoption. The EU CSRD regulation (mandatory sustainability reporting for 50,000+ large companies beginning 2024) has been the primary market driver — fashion brands facing mandatory Scope 3 emissions disclosure have moved from voluntary sustainability reporting to procurement-driven software requirements. Carbonfact's fashion industry specialization (versus general-purpose carbon accounting tools like Watershed or Persefoni) enables the material-level emissions database depth that general tools lack. Alven's Paris-based fashion and luxury tech investment focus reflects the French fashion industry's concentrated ESG reporting requirements. The 2025 strategy focuses on growing the EU enterprise fashion brand contracts for CSRD compliance, building the automated supplier engagement portal (collecting facility-level energy and process data from Tier 1 and Tier 2 suppliers), and expanding the product eco-score consumer-facing certification program. ## Frequently Asked Questions ### What is Carbonfact?
