What is Carta?

Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.

The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.

What is SolidInvoice?

SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.

SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.

Carta is pulling fund back-office paperwork in-app, then walking into the deal team's CRM.

◆ Current state

The recent run is dominated by one pattern: operations that used to happen over email and PDF are being moved inside Carta. Securities transfer instructions now send and track from the app, investors collect their own securities accounts through a self-service portal, wire account setup is AI-assisted, and spousal consent runs through fillable templates. The quarterly compensation benchmark refresh continues on schedule, and the newest release steps outside fund administration entirely with a CRM Chrome extension for deal teams.

◆ Where it's heading

Carta is widening from the system of record for the cap table into the system that runs the workflows around it — in-kind distributions, wires, KYC, and consents each moved from offline exchanges to tracked in-app state. The through-line is fewer handoffs to email and more self-service by the counterparty, with AI applied to the messiest input first. The CRM extension marks a second front: rather than deepening fund ops, it goes after where deal and investor-relations teams spend their day.

◆ Prediction

The distribution workflow now has account collection, transfer instructions, and status tracking in place, so the plausible next step is closing the loop into execution and confirmation without leaving Carta. On the CRM side, expect the browser capture to connect back to Carta's own entity and cap-table data, which is the only thing that would differentiate it from a general-purpose CRM.

S5.0

SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.

◆ Current state

SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.

◆ Where it's heading

After the large 3.0 release in June, work has moved to hardening: upgrade paths, packaging (Snap, static PHP builds) and correctness in payments and reporting. The mention of MCP payments shows AI-agent access is already wired into billing, though the entries don't detail it.

◆ Prediction

Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
