Headless pricing and packaging layer for plans, entitlements, credits, versioned changes, and embeddable paywalls.
Stigg is a headless pricing and packaging platform: it externalizes the plan catalog, entitlements, and pricing logic that most SaaS companies hard-code across their app, billing tool, and CRM into one API-driven layer. Product and engineering teams define plans, features, limits, and credit grants in Stigg, enforce them in-app through its SDKs, and render pricing tables and paywalls from the same source of truth. It sits between the product and the billing system in the define-what-you-sell and entitlement layers, letting pricing change without redeploying code.

Stigg's insight is that pricing agility is an architecture problem — the reason repackaging takes quarters is that plan logic is smeared across codebases. By making the catalog, entitlements, and their versioning a dedicated service with real-time enforcement and grandfathering built in, Stigg turns pricing changes into configuration. Few tools treat plan versioning and legacy-plan management as first-class the way it does.
No — it sits in front of one. Stigg owns what a customer is entitled to and what the packaging looks like, then syncs the commercial outcome to a billing engine that handles invoicing and payment. The division of labor is packaging and enforcement in Stigg, money movement in billing.
Pricing changes that take engineering quarters. If launching a new tier means touching feature checks scattered through the codebase, updating the billing catalog, and hand-migrating existing customers, plan logic has become architecture debt — centralizing it is the fix.
Through plan versioning: new versions can apply to new signups while existing customers stay grandfathered on the terms they bought, and migrations happen deliberately rather than as a side effect. That makes iterative pricing changes safe instead of breaking.
