Increase vs Stigg: at a glance
What is Increase?
A banking-as-a-service API that now sells compliance and blockchain rails, not just payments
Increase ships a quarterly newsletter rather than a running changelog, so each entry bundles a quarter of API work. The last three quarters have moved past core payment rails into the surrounding infrastructure: managed compliance, entity onboarding sessions, 3D Secure, push provisioning and IP-restricted API keys. SDK coverage has widened to C#, PHP and Ruby, and the documentation was reworked to be readable by LLMs.
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.

Increase

A banking-as-a-service API that now sells compliance and blockchain rails, not just payments
◆ Current state
Increase ships a quarterly newsletter rather than a running changelog, so each entry bundles a quarter of API work. The last three quarters have moved past core payment rails into the surrounding infrastructure: managed compliance, entity onboarding sessions, 3D Secure, push provisioning and IP-restricted API keys. SDK coverage has widened to C#, PHP and Ruby, and the documentation was reworked to be readable by LLMs.
◆ Where it's heading
The arc runs from moving money to operating a bank program end to end. Early quarters added rails (FedNow, Push-to-Card, check transfers); recent ones add the compliance, onboarding and dispute machinery a customer would otherwise build or buy separately. Q2 2026 adds blockchain transfers alongside managed compliance, and flags cross-border payments and lending APIs as next.
◆ Prediction
Expect the cross-border payments and lending APIs named in the Q2 2026 letter to ship as the next quarter's headline, extending the same pattern of absorbing adjacent financial products into the core API.
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.
