Summation Raises $35 Million to Launch AI Platform Transforming Enterprise Decision-Making

Summation, a Bellevue‑based enterprise AI startup, has announced that it has raised US$35 million in its latest funding round. The funding round was backed by leading venture firms Benchmark and Kleiner Perkins.

Summation aims to redefine how businesses make strategic decisions by offering real-time, verified insights across large and fragmented internal data systems. Its platform — built on a proprietary AI Calculation Engine — can analyze data across ERP, CRM, EPM, and warehouse systems, running thousands of analyses in parallel. This capability enables companies to automate complex workflows such as variance analysis and reporting, while surfacing actionable strategic opportunities that might otherwise be hidden.

According to the company, what once took weeks of manual data preparation can now be completed in minutes. By delivering audit-ready results tied directly back to source data, Summation hopes to give enterprise leaders the clarity and confidence needed to steer businesses through uncertain or fast-changing environments.

Founded in 2024 by former executives of Opendoor, including CEO Ian Wong, Summation says its platform is built for finance, operations, and executive teams that need to navigate complex strategic decisions. The company has already started working with major clients, and early deployments are reported to have helped uncover millions of dollars in growth and savings opportunities for customers — for example, one customer used the platform to accelerate reporting cycles and identify actionable business drivers that had previously gone unnoticed.

With this $35 million injection, Summation plans to accelerate product development, expand its engineering and research teams, and scale sales and marketing to broaden its customer base. The funding will support further refinements to its AI Calculation Engine, deepen its automation and analysis capabilities, and enable faster onboarding of new enterprise customers.

As companies across industries grapple with increasing data complexity and the need for fast, informed decisions, Summation’s timing could not be more relevant. By combining AI-scale computation with auditability and enterprise-grade robustness, the startup is positioning itself as a foundational layer for next-generation enterprise decision infrastructure. With its newly secured funding and ambitious roadmap, Summation appears set to be a key player in the growing wave of AI-native enterprise software solutions.
