Every field

What we track, and where it came from

One row per field. The source link goes to the upstream project; the date is when that value was last observed, not when this page was built.

Every tracked field for Letta, with its source, its date, and where it stands.

History

How these numbers moved

Built from the observation log rather than from a current-state row. A mutable cell could not produce this at any price, and no backup would reconstruct it.

Hiring

Open roles mentioning this

Matched from the job board by name. A mention is not a requirement — most listings name several tools, and which of them a role actually needs is recorded nowhere.

No open roles mention Letta. That is a fact about the roles we track, not about how widely it is used — the board covers agent-engineering roles at the companies we follow, and most tools never appear in one.

Compare Letta

Side by side, every tracked field, each figure still carrying the source that reported it and when.


Every figure on this site resolves to the source that reported it, the moment it was observed, and how it was measured. A value that fails validation is withheld rather than shown — withheld means we refused to publish it, not that it is zero.
