Summation

We envision a future where enterprise complexity and data chaos no longer hinder leadership decisions but instead illuminate the path to clarity and confident action. At Summation, we are pioneering an AI-native decision infrastructure that transforms thousands of fragmented data points into real-time, actionable insights, empowering executives to navigate complexity with unparalleled precision.

Driven by our proprietary AI Calculation Engine, we are redefining the boundaries of what decision-making means in the enterprise world. Our platform converges innovation in AI and deep integration with existing systems to create a seamless fabric of verified knowledge, enabling leaders to evaluate hypotheses at scale and with audit-ready confidence.

Summation is committed to building an intelligent foundation for tomorrow’s enterprises—where clarity, speed, and trust in decisions shape the strategic future, unlocking new growth horizons informed by data-driven certainty.

When we first looked at Summation, what caught our attention wasn't just another AI platform – it was their laser focus on solving one of the most challenging problems in enterprise leadership: making better decisions with incomplete information. Founded by Opendoor veterans Ian Wong and RC Ramarathinam, this Bellevue-based startup is tackling executive decision-making with a fresh perspective.

Why This Matters Now

In today's fast-moving business environment, we're seeing executives drowning in data yet starving for insights. What Summation brings to the table is genuinely different – their Decision-Grade AI Platform can analyze thousands of scenarios simultaneously, something that would take traditional teams weeks or months to process. It's like giving leaders a supercharged analysis team that never sleeps.

The Tech That Impressed Us

The real magic happens in their AI Calculation Engine. Instead of just presenting data, it actively hunts for hidden performance drivers and opportunities. We were particularly impressed by how it integrates with existing enterprise systems – there's no ripping and replacing required.

Their commitment to verification is noteworthy too. Every insight is audit-ready, which is crucial for enterprise adoption. This isn't just AI throwing out suggestions; it's providing defendable, traceable recommendations.

Who Should Pay Attention

With $35 million in funding from Benchmark and Kleiner Perkins, Summation isn't just another startup with big dreams. They're clearly built for enterprise-scale challenges, and their SOC 2 TYPE II compliance shows they're serious about security.

While this platform isn't for everyone (it's clearly aimed at large enterprise leadership teams), we think it's worth watching for any organization dealing with complex, high-stakes decisions. The ability to run thousands of analyses in real-time could be a game-changer for companies struggling with strategic clarity.
