What is Carta?
Carta is rebuilding core valuations and equity flows around an agentic ERP.
Carta is shipping across three lanes at once: agentic rebuilds of core financial workflows, deeper compensation data via HRIS, and global compliance reach. The Portfolio Valuations rewrite under the new Agentic ERP signals an architectural reset rather than feature polish. Quarterly benchmark refreshes and fund-admin views (Data Explorer, Intercompany Balances) keep the existing surface area accreting in parallel.
What is Kill Bill?
Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.

Carta
6.3FINANCE
Carta is rebuilding core valuations and equity flows around an agentic ERP.
◆ Current state
Carta is shipping across three lanes at once: agentic rebuilds of core financial workflows, deeper compensation data via HRIS, and global compliance reach. The Portfolio Valuations rewrite under the new Agentic ERP signals an architectural reset rather than feature polish. Quarterly benchmark refreshes and fund-admin views (Data Explorer, Intercompany Balances) keep the existing surface area accreting in parallel.
◆ Where it's heading
The center of gravity is moving toward agent-driven workflows that fold valuations, equity docs, and reporting into one operating layer for finance teams. Compensation data is being pulled in from HRIS and refreshed on a quarterly cadence, suggesting Carta wants to be the system of record for both the cap table and the people behind it. International expansion — starting with Australia's ESS suite — points to a multi-jurisdiction compliance roadmap.
◆ Prediction
Expect more modules — financial reporting, fund admin, document workflows — to be re-shipped as agent-native within the next two quarters. A second jurisdiction (likely UK or Canada) is the obvious next compliance bundle.

Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
◆ Current state
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.
◆ Where it's heading
The recent arc is hardening the billing core — making invoice runs fail safely, speeding multi-tenant queries, and giving operators more control over configuration and retries. The 0.25.0 cut suggests accumulated work is being promoted to a new line, though the in-feed notes don't yet detail it.
◆ Prediction
Expect 0.25.x to continue the invoice-resilience and operability focus, with detailed release notes following the tag; the next feed entries are likely 0.25.x bug-fix points.
