Founded in 2026 and headquartered in New York, Shackleton AI is the agentic operating system for development and construction. The platform unifies development, preconstruction, project and field management, finance and communications in a single system spanning site selection through project turnover. AI agents operate across shared data to handle administrative tasks, coordinate projects and identify risk. Shackleton was founded by Michael Ragheb, Hassan Yasin and Olexandr Kaltsev, who previously scaled a tech-enabled general contractor to $35 million in annual revenue. Shackleton supports owners and builders in more than 15 states, with more than $1 billion in project value managed on the platform.
