Simon Data

Simon Data — now trading as Simon AI, and acquired by Monetate on 30 July 2026 — is a composable, AI-first customer data platform for marketing teams. It reads customer data directly from a cloud warehouse (Snowflake, BigQuery, Redshift, Azure) without ETL, resolves identity into unified profiles, and activates segments across email, SMS, push, paid media and 70-plus downstream tools including Braze, Iterable, Attentive, Klaviyo, Salesforce Marketing Cloud, Amazon Ads and The Trade Desk. Two callable APIs are published: the Simon Signal Event Ingestion API, which accepts fourteen documented behavioural and transactional event types at a single collect endpoint, and the premium Audience API, which returns one contact profile at a time for send-time personalisation. Outbound webhooks and a Real-Time Content client cover the reverse direction, calling customer endpoints at send time.

Simon Data publishes 2 APIs on the APIs.io network: Contacts API and Events API. Tagged areas include Customer Data Platform, CDP, Marketing Automation, Audience Segmentation, and Event Tracking.

The Simon Data catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.

Simon Data’s developer surface includes authentication, changelog, sandbox, code examples, documentation, API reference, getting-started guide, and 45 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/simon-data: open an issue to ask a question, or submit a pull request to add artifacts.
