41 agent-memory launches in seven months of 2026 — nearly half claim both temporal and relational memory

Asked:

“Find publicly announced agent-memory products launched in 2026. Extract product, company, memory approach, storage model if stated, whether it supports temporal or relational memory, launch date, and source. Return a table. Prefer primary announcements over roundup blog posts.”

This best-effort public-web inventory covers 41 publicly announced agent-memory products or substantial named memory-feature releases dated 6 March through 22 September 2026, current through 23 September 2026, drawn from 24 independent hosts with one source URL per row. It is not a claim that a fixed universe of launches exists.

Launch timeline, March–September 2026

temporal and relational — both explicitly stated temporal only stated relational only stated neither stated (or relational stated as no) ◦ hollow ring = maker-issued wire release or syndication. Hover a mark for details.

19 of 41 products explicitly claim both temporal and relational memory; the deepest example, blog.cloudflare.com, fuses five parallel retrieval channels over SQLite-backed Durable Objects plus a vector store.
Local file- and SQLite-first designs form a distinct open-source segment — 11 of 41 rows are open-source releases, such as the no-database Markdown-plus-JSONL system on github.com.
Hyperscalers entered mid-year: Microsoft's Foundry memory in April (devblogs.microsoft.com), then Huawei Cloud's PB-scale AMS and Tencent Cloud's Team Memory in July–August via wire releases on prnewswire.com-style channels.
12 of 41 rows rest on maker-issued wire releases or syndicated copies (marked with hollow rings), not independent reporting — for example Yugabyte's Meko on businesswire.com.

Method: best-effort public-web inventory of publicly announced agent-memory products and substantial named memory-feature releases dated 2026-03-06 to 2026-09-22, compiled 2026-09-23. 41 rows, one qualifying product per row, each backed by exactly one source URL across 24 independent hosts; no URL supports more than one row. “Yes” for temporal or relational memory means the source explicitly described the capability; “Not stated” means it was not explicit and is not a “No.” Blank storage means the announcement stated no storage model. Sources marked “wire” are maker-issued press releases or syndications, not independent reporting. Audit fields (total products, per-URL row counts, host counts) are summarized here and omitted from the table for space.
