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 maintains a steady multi-product release cadence across its hospitality POS and payments stack.
Shift4 operates a mature, multi-product payments and POS platform targeting hospitality venues—restaurants, stadiums, hotels. The release pattern across the last 10 entries is predictable: bi-weekly Venue POS drops (quick service, loyalty, menu manager, ordering web), weekly Customer Hub updates, and a separate Gift Card & Loyalty track. Multi-language release notes (English, French, Portuguese) confirm a broad international deployment base, particularly in European and Latin American venues.

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 maintains a steady multi-product release cadence across its hospitality POS and payments stack.
◆ Current state
Shift4 operates a mature, multi-product payments and POS platform targeting hospitality venues—restaurants, stadiums, hotels. The release pattern across the last 10 entries is predictable: bi-weekly Venue POS drops (quick service, loyalty, menu manager, ordering web), weekly Customer Hub updates, and a separate Gift Card & Loyalty track. Multi-language release notes (English, French, Portuguese) confirm a broad international deployment base, particularly in European and Latin American venues.
◆ Where it's heading
This is a platform in operational steady-state, not a growth phase. The velocity is maintenance-oriented: patch releases, localized documentation updates, and component-level stability improvements. No new product surface or architectural shifts are visible in the recent entries. The Customer Hub weekly cadence suggests some incremental feature work, but the entries don't surface what that work is—it's below the threshold of strategic signaling.
◆ Prediction
Shift4 will continue its quarterly Venue POS release cycle and weekly Customer Hub drops without obvious directional change. Any strategic moves—new verticals, platform integrations, pricing changes—would need to show up in a Customer Hub or Venue release with substantive feature content to read as directional.
