DocuSign rebuilt eSignature with AI and is now targeting the full contract lifecycle.
DocuSign has fully reoriented around its Intelligent Agreement Management (IAM) platform, with a proprietary AI engine called Iris now powering both the signing experience and the contract review workflow. The January 2026 eSignature redesign was the most visible signal: AI automates document prep, assists signers in real time, and reduces manual steps at the moment of execution. The March 2026 AI-Assisted Review extension takes Iris further upstream into negotiation and redlining.
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.

The March 2026 AI-Assisted Review extension takes Iris further upstream into negotiation and redlining.
The product is moving systematically up the contract lifecycle — from post-signature management (where IAM started) backward through signing and now into pre-signature negotiation. Each step adds another layer of Iris AI to replace human review work. The logical terminus is a fully AI-mediated agreement workflow where Iris handles generation, review, negotiation, and execution with humans in an approval role only.
DocuSign's next likely move is deeper integration between Iris and enterprise data sources (CRM, ERP) so that agreement insights flow directly into existing business systems — or an agentic negotiation mode where Iris proposes and marks up contract terms autonomously.

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.
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.
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.
