ESG Reporter

ESG Reporter is a SaaS platform that helps European SMEs collect, structure and report ESG data compliant with ESRS standards — so they can respond to sustainability data requests from their corporate clients. Includes a guided ESRS questionnaire, carbon footprint calculator (Scope 1 & 2), compliance dashboard, automated PDF report generator, and a supplier portal where large companies invite their vendors directly. Built with Next.js, Convex, Stripe and Claude API for contextual AI assistance.

Value Proposition

La única plataforma diseñada para la PYME proveedora, no para la gran empresa. Cuestionarios ESRS en lenguaje llano, calculadora de huella de carbono conectada a facturas de energía, y exportación directa en formato compatible con portales corporativos. Precio 10× menor que cualquier competidor enterprise. Además, sirve como pasarela para que las PYMEs accedan a contratos con grandes corporaciones que necesitan datos ESG de su cadena de suministro (Scope 3).

Target Customer

Primario: PYMEs europeas de 50–1.000 empleados que son proveedoras de grandes corporaciones obligadas por CSRD.
Secundario: Consultoras de sostenibilidad que gestionan múltiples clientes.
Canal de distribución: Las propias grandes empresas que piden los datos a sus proveedores (invitación vía email → portal del proveedor).
