# QUIXOTIC

> QUIXOTIC is a modular, cloud-native SaaS platform that automates billing, DSO integrations, switching, contracting, and energy community management for energy retailers (comercializadoras), utilities, and ESCOs across Europe. AI-first architecture. 25+ clients. Over 1 million supply points (CUPS) managed in Spain. TRL 8.

QUIXOTIC is the operational backbone for energy retailers who need to automate regulated processes end-to-end — from distributor file exchange (XMLs, ATRs, switching workflows) through invoicing and regulatory reporting. The platform is the only solution capable of billing energy on a calendar month basis with automatic correction and compensation. All modules share a single multi-commodity, multi-brand, multi-license data model. Founded in 2021 by the team behind Calibre 360, a technology consultancy specialized in energy retail. Winner of the Premio Innovación Energética 2023 (La Razón). Featured in Expansión (October 2024). Finalist in Energy Tech Challengers 2026, Climate Software X track (Energy Tech Summit, Bilbao).
