Changelog

PostSig changelog

Every tracked product and technology change at PostSig, dated and sourced. Each entry names the change, its impact and the live source it was graded from.

Product and technology changes only. Funding rounds, valuations, partnerships and awards are excluded, and an acquisition appears only where there is direct product impact. Every entry cites a live retrieved source. Changes to the index's own records are not changelog material; a corrected record carries its own dates.

Product / capability

PostSig expanded its post signature contract platform for finance, procurement, market data and operations teams with four connected capabilities: Spend and Invoices (amortised spend, budget to actual, cost allocation, multiple currencies and invoice reconciliation), Inventory and Entitlements (with a new Bloomberg Terminal Management Module), Products and Pricing (which flags continued billing for removed products) and Vendors. PostSig MCP exposes more than 30 tools to customer built applications and AI assistants. Data is hosted in the US or EU region the customer selects, and CJC is named as the first enterprise deployment.

Buyer relevance. Legal and procurement teams can tie what a contract says to what is actually being billed and used, which is where overpayment on market data and software usually hides. Regional hosting answers the residency question for EU customers.

Correct a record, or ask how something was graded

Every grade and every signal on this index is drawn from public sources and dated. If a record is wrong, out of date, or missing an artifact the index did not locate, send the source and it will be reviewed and the record redated. Vendors are welcome to submit documentation. Nothing on this index is for sale, including a listing, a placement, or a grade.

AI Legal Index

The AI Legal Index is an independent index that tracks changes to AI vendors in legal. It holds 303 vendors across 9 categories, each graded on the same 15 capability axes and recorded against 12 legal signals, from public sources. No vendor pays for inclusion, placement, or rating.

The AI Legal Index is an editorial reference. It is not a regulatory body, not a law firm, and nothing published here is legal advice or a recommendation to retain or avoid a vendor. Records are verified against published sources, bar guidance and public court records. Where a record reads not addressed, the material was not located in public sources on the date shown. See the Methodology page for evaluation standards and limitations.
