Independent expertise. Integrated delivery.

Founded by practitioners who have worked in major capital projects from both the owner and contractor side, IPP exists to close the gap between project ambition and project reality.

Built by project practitioners, for project teams.

IPP was founded by senior project professionals who built their careers across the full delivery ecosystem — working with owners, EPCM teams, engineering providers, and contractors. Its establishment in Latin America responds to the need to fill the gap given by limited access to independent and technically capable advisory and controls capacity, in response to the complexity and pace of large capital investments.

The firm was built around a core belief: the most valuable project advice comes from people who have held personal accountability for delivery. That hands-on experience — combined with disciplined governance, transparent records, and clear performance visibility — helps teams make better decisions under pressure, with imperfect information and real consequences.

Today, IPP supports project owners, contractors, and engineering providers — from early-stage studies through execution, commissioning, and handover to Operations. We integrate seamlessly into client structures to strengthen cost, schedule, risk, and commercial outcomes, and to improve predictability and stakeholder confidence.
