About
Summation is an enterprise AI platform founded in 2024 by Ian Wong and Ramachandran Ramarathinam, formerly of Opendoor, to solve the problem of unreliable data slowing executive decision-making. The platform combines an AI Calculation Engine, Verified Tasks, and a Deep Dive agent orchestration capability that deploys AI agents to explore thousands of questions in parallel. Summation integrates with existing ERP, CRM, EPM, and data warehouse systems, delivering audit-ready results in real time and going live in weeks rather than months. The company targets enterprise finance and operations teams who need decision-ready insights without manual analysis overhead, and is SOC 2 Type II certified.
