What is Lago?
Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
What is Stigg?
Stigg ships natural language contract management, completing its build-out as an AI-native commercial operations layer.
Stigg has assembled a full commercial operations platform in the span of a few weeks. Contract Management moved from beta (August) to AI-skill-powered natural language management (September 14), the data export destinations expanded to connect Stigg's commercial data to existing BI stacks, and Eurozone pricing collapsed 21 per-country configurations into one. The entitlements platform's Go SDK also gained edge API support, reducing the latency of enforcement checks.

Lago
0.0FINANCE
Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
◆ Current state
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
◆ Where it's heading
Lago is positioning itself as the billing backbone for AI-native and credit-economy products — pricing units, prepaid wallet primitives, and an MCP server are not generic SaaS billing features. In parallel it's pulling forward enterprise governance: roles, security logs, e-invoicing, granular API endpoints. The combination reads as a deliberate move upmarket, with the AI-billing angle as the wedge for new logos and the governance work as the ceiling-raiser for existing ones.
◆ Prediction
Expect more agentic surface (additional AI agent personas beyond the Billing Assistant, or MCP server hardening with action-confirmation flows), and continued e-invoicing jurisdiction coverage following the France template — Italy, Belgium, or another Peppol-aligned market would be the natural next stop.
Stigg
7.5FINANCE
Stigg ships natural language contract management, completing its build-out as an AI-native commercial operations layer.
◆ Current state
Stigg has assembled a full commercial operations platform in the span of a few weeks. Contract Management moved from beta (August) to AI-skill-powered natural language management (September 14), the data export destinations expanded to connect Stigg's commercial data to existing BI stacks, and Eurozone pricing collapsed 21 per-country configurations into one. The entitlements platform's Go SDK also gained edge API support, reducing the latency of enforcement checks.
◆ Where it's heading
Stigg is systematically replacing ad hoc spreadsheet and CRM workarounds for RevOps teams managing sales-led deals. The arc is clear: start with self-serve pricing/entitlements, add contract management for custom enterprise terms, layer AI to make that management accessible without developer involvement, and export everything to data warehouses so it stays in sync with the rest of the business. The goal is to be the system of record for all commercial terms — self-serve and sales-led — rather than a developer dependency for pricing enforcement.
◆ Prediction
The stigg-contracts AI skill will likely expand to handle contract amendments and renewal queries, and a tighter Salesforce/HubSpot integration to close the loop from CRM opportunity to provisioned entitlements is the obvious next move — right now a deal still requires a human to bridge the two systems.
