Banking platform pushes into A/R and AI-startup banking, becoming a full SMB finance OS.
Rho is expanding from a corporate banking and card platform into a consolidated finance operating system for SMBs. Recent shipments add invoicing, mobile reimbursements, mobile deposits, and tighter accounting integrations alongside the existing card and bill-pay surface. The Rho AI Stack — bundling Claude, AWS, Lovable, and ElevenLabs credits with banking — also positions Rho explicitly toward AI-native startups.
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.

The Rho AI Stack — bundling Claude, AWS, Lovable, and ElevenLabs credits with banking — also positions Rho explicitly toward AI-native startups.
The product is moving along the same arc as Brex, Mercury, and Ramp: collapse spend, bank, bill-pay, and now invoicing into one ledger. Recent releases are filling the white space between banking and accounting, with deeper Puzzle and QuickBooks plumbing rather than headline new modules. The AI Stack pivot suggests a deliberate vertical: capture AI-native startups whose largest non-payroll spend is infrastructure credits.
Expect invoicing to leave beta with payment acceptance rails, and the AI Stack to expand to more vendors as Rho leans into the AI-startup wedge. Bill-pay and reimbursements UX work signals continued mobile-first push.

Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
