AI context announcements from April to October 2026

This memo covers announcements made between April and October 2026 by vendors on this site and by the two big data platforms. It is a recap of dated events, published on 19 October 2026, with each item linked to the page where we read it. Where a date comes from a search-result summary rather than the page itself, the source line says so.

On 2 April 2026, Databricks announced that Business Semantics, including metric views, was generally available and open source in Apache Spark. Databricks describes Unity Catalog Semantics as an open semantic layer that centralizes business definitions for BI, apps and AI. For teams on Databricks, this moved metric definitions into the platform they already run.

On 10 June 2026, Jedify announced a $24M Series A led by Norwest, with Snowflake Ventures among the investors, bringing its total to just over $33 million. Jedify describes an autonomous context graph for agentic applications that captures metric definitions, entity relationships, lineage, permissions, business rules and terminology, from structured systems and from documents, Slack and meeting recordings. The Weather Company is the named customer.

Three patterns stand out. First, every category is converging on the same promise: context an agent can use. Catalogs add ontologies and MCP servers, context platforms generate metrics, semantic layers add chat and agent interfaces. Second, the data platforms are pulling catalog and semantic features inside: Snowflake through Horizon Context and its Select Star acquisition, Databricks through Unity Catalog Semantics. Third, funding is still going to standalone context vendors, Euno and Jedify among them, alongside the platforms' own features.

Two older events set the scene and are worth knowing. DataHub announced a $35M Series B led by Bessemer Venture Partners on 21 May 2025, for $65M raised in total, and completed its rebrand from Acryl Data. ServiceNow announced its agreement to acquire data.world on 7 May 2025, and Snowflake announced its agreement to acquire Select Star's team and technology on 24 November 2025. Atlan's Series C of $105M, led by GIC and Meritech Capital, dates from May 2024. Each of these shaped the vendor set we rank today: two catalogs are now inside larger platforms, and the context platforms that remain standalone are well funded.

Release dates matter more than usual. Several of the features that define agent readiness were in preview or early access when we read the vendors' pages: Horizon Context, and four of Alation's six new products. Ask every vendor which features in your shortlist are generally available today, and score only those.

We update the ranking when a vendor's public pages change a criterion. The scoring model explains how, and the platform-native page covers Snowflake and Databricks in more detail.
