Iñigo Rengifo Melia

Iñigo Rengifo Melia is the co-founder and CEO of Concentro and Folio, two companies transforming how clean energy projects are financed and managed.

An electromechanical engineer by training with a strong background in energy, Inigo began his career as the first employee at a startup studio, where he was part of the founding team of two early-stage companies. He then joined McKinsey as a management consultant, specializing in energy including a nearly 10-month engagement helping one of Spain's largest utilities build and launch a distributed generation platform.

Concentro is a hands-on tax credit transferability platform focused primarily on distributed generation, managing the entire process from diligence to transaction management to legal documentation. The firm works with both sellers (IPPs, developers, sponsors) and buyers (corporations seeking vetted tax credits).

Folio, spun out from Concentro's internal tooling, is an AI-powered diligence and project finance platform that helps clean energy teams process documentation faster, maintain precision, and manage the full lifecycle from financing preparation through asset management.
