Summation

Summation is an enterprise AI analyst platform that automates recurring business work — financial reviews, forecasts, models, and executive-ready decks — by connecting to a company's data sources (ERPs, data warehouses, and spreadsheets) and producing verified, source-traced reports in the format teams already use. Its AI agent "Addison" runs playbooks across finance, operations, and sales, tracing every number back to its source so outputs are audit-ready and SOC 2 Type II compliant. Founded by Ian Wong (CEO) and Ramachandran "RC" Ramarathinam (CTO), formerly of Opendoor, Summation is backed by Battery Ventures. The company operates a customer application, product documentation, and a public Trust Center, but does not currently publish a public developer API surface.

Summation is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Analytics, and Finance.

Summation’s developer surface includes pricing, engineering blog, documentation, signup flow, and 14 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/summation: open an issue to ask a question, or submit a pull request to add artifacts.
