Michael T. Puntillo, a veteran of the fourth-generation family real estate firm PX4 Development, has announced a significant pivot in his career. Leaving behind his role at the Manhasset-based firm, Puntillo is entering the burgeoning “proptech” space with the launch of DPI Enterprise (Digital Properties International). The new venture aims to bridge the gap between traditional real estate operations and modern artificial intelligence, offering customized automation solutions designed to integrate seamlessly into existing industry workflows.
## Bridging the Gap Between Real Estate and AI
For years, the real estate sector has struggled with fragmented data and labor-intensive, repetitive manual processes. While many tech startups offer “off-the-shelf” solutions that force firms to overhaul their entire operating infrastructure, DPI Enterprise is taking a different approach. Puntillo’s strategy focuses on building AI systems that work in tandem with the software, data practices, and internal approval processes that real estate firms have already spent years refining.
By deploying custom automation, DPI Enterprise targets a broad array of industry players, ranging from large-scale construction firms and multifamily owners to public housing authorities and affordable housing nonprofits. The goal is to strip away the time-consuming administrative tasks—such as manual data entry, routine documentation, and basic document parsing—that occupy valuable staff time. By automating these “back-office” functions, the firm hopes to empower teams to prioritize high-level strategic decision-making that requires human insight rather than brute-force data processing.
## Introducing Janus: A New Standard for Underwriting
The flagship offering from DPI Enterprise is an AI-powered underwriting agent named Janus. Underwriting is often considered the most critical, yet bottleneck-prone, part of the real estate investment cycle. Janus is designed to function as an intelligent layer that learns from a firm’s historical deal data to assist investment teams in evaluating incoming opportunities.
Unlike standardized AI tools that rely on generic market benchmarks, Janus learns the specific investment “DNA” of the firm that employs it. By training on proprietary datasets and past underwriting successes, the system can assist in identifying risks and opportunities in new projects more efficiently. According to Puntillo, this product exemplifies the core mission of his new company: providing precision-engineered tools rather than broad, one-size-fits-all software.
## Lessons Learned at PX4 Development
Puntillo’s decision to launch DPI Enterprise is rooted in the operational challenges he observed while navigating the complex development landscape at PX4. During his tenure, he was integral to several high-profile projects, including the 13-acre mixed-use Aurora development in Central Islip and the repositioning of 120 Jericho Turnpike for the New York Institute of Technology.
Reflecting on his departure, Puntillo noted that his time at the family firm provided the foundational mindset necessary for his transition into the tech space. “PX4 taught me what it means to develop for the long term rather than the next quarter,” he stated. He credits his father, Michael F. Puntillo, and the broader PX4 team with fostering the professional relationships and industry experience that shaped his current vision.
As DPI Enterprise begins its rollout, it enters a competitive marketplace where AI adoption is becoming a necessity for firms aiming to maintain margins in a high-interest-rate environment. By focusing on bespoke automation that respects the existing workflows of seasoned real estate professionals, Puntillo is positioning his startup to move beyond the “AI hype cycle” and provide practical, measurable value to firms struggling with operational drag. Whether DPI Enterprise can successfully modernize the traditionally slow-moving real estate industry will depend on its ability to prove that its “Janus” agent can indeed handle the nuance of complex underwriting at scale.
