CDISC -Technologies Pvt Ltd (Center for Development of Innovative & Sustainable Construction Technologies) is a Calicut-based deeptech construction startup transforming the built environment through sustainable, prefabricated, and modular solutions. Founded by civil engineer Er. Jeesh Venmarath, CDISC is the innovator behind the PEN Foundation (Pre-Engineered Nail Foundation) and Modular Net Zero Energy (MNZE) Homes—two groundbreaking systems designed for speed, sustainability, and climate resilience. The PEN Foundation is a patented, tree-root-inspired technology that avoids deep excavation, preserves groundwater, and offers rapid deployment, making it ideal for sloped, remote, or ecologically sensitive terrains. MNZE Homes, on the other hand, are prefabricated dwellings embedded with renewable energy, smart automation, and water management systems, offering energy independence and the potential to break even in 15 to 25 years
