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 Shift4?
Shift4 is on a steady venue POS release cycle with Payment Links added to Customer Hub.
Shift4 is a payment platform primarily serving hospitality, stadiums, and venue operators. Its recent cadence is stable and predictable: quarterly venue POS releases (Q3-R2), weekly Customer Hub updates, and periodic operational announcements (third-party service changes, SSO button additions). Payment Links landing in Customer Hub (week 35) is the most user-visible feature addition — enabling venues to collect payments without a full POS integration.

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.
Shift4
5.0FINANCE
Shift4 is on a steady venue POS release cycle with Payment Links added to Customer Hub.
◆ Current state
Shift4 is a payment platform primarily serving hospitality, stadiums, and venue operators. Its recent cadence is stable and predictable: quarterly venue POS releases (Q3-R2), weekly Customer Hub updates, and periodic operational announcements (third-party service changes, SSO button additions). Payment Links landing in Customer Hub (week 35) is the most user-visible feature addition — enabling venues to collect payments without a full POS integration.
◆ Where it's heading
Shift4's product development is infrastructure-oriented — POS firmware cycles, cloud printing dependencies, OKTA-based SSO for internal access. There are no signals of a major new product surface in this window. The cadence suggests a well-maintained platform serving its existing verticals rather than a company in active expansion mode.
◆ Prediction
Expect continued venue POS improvements and gradual expansion of Customer Hub's self-service payment capabilities — Payment Links suggest a move toward enabling venues to handle ad-hoc revenue collection without POS hardware dependency.
