Stigg

Stigg is a usage runtime platform for AI products that enforces credits, entitlements, and usage limits in real time — deciding what customers, users, and agents are allowed to do across AI requests at under 10 milliseconds p99 latency — used by Miro, Webflow, PagerDuty, and Upwork. Its core capabilities cover real-time entitlement enforcement, financial-grade credit infrastructure (wallets, ledgers, audit trails), high-throughput metering (1M+ events/second) with Bring-Your-Own-Cloud options, and feature-flag-style entitlement configuration outside the codebase for rapid changes. Deployment options range from Stigg's hosted Cloud API to full BYOC/BYODB for teams needing infrastructure control, with integrations across Stripe, Zuora, Chargebee, Snowflake, and BigQuery. SOC 2 and ISO 9001:2015 certified; pricing isn't published on the main page. Good fit for an AI product team that needs to enforce usage-based billing and per-agent spend limits in real time, rather than reconciling usage after the fact.
