Orchestration vs Embedded Payment Layer
Gr4vy and Shuttle both sit between software and payment processors. Both connect to multiple PSPs. But they're built for different users and solve different problems.
Gr4vy is a cloud-native payment orchestration platform. It provides a hosted vault, smart routing and a no-code flow builder, deployed as a dedicated cloud instance or multi-tenant SaaS. Most of its users are merchants (or their payment engineering teams) optimising their payment stack, and it also offers Gr4vy for Platforms, with white-label elements and a PSP chosen per sub-merchant.
Shuttle is an embedded payment layer for platforms. It gives software companies the ability to offer multi-PSP payment infrastructure to their merchants, with white-label onboarding, checkout, merchant portal, and multi-channel support built in.
Same category on a vendor shortlist. Different products in practice.

Where Gr4vy Wins
Cloud-Native Architecture
Gr4vy was built from scratch as a cloud-native platform, with no legacy code and no acquired components stitched together. The architecture supports dedicated cloud instances per customer, meaning your payment data and processing logic can run in an isolated environment rather than shared multi-tenant infrastructure. For merchants with strict data residency or isolation requirements, this is a genuine differentiator.
No-Code Flow Builder
Gr4vy's flow builder lets payment teams visually configure transaction routing, retry logic, and fraud checks without writing code. The drag-and-drop interface makes it accessible to payment operations teams who want to adjust routing rules without engineering involvement.
Modern Vault
Gr4vy Vault is a purpose-built, cloud-native PCI Level 1 vault. It's newer and architecturally cleaner than legacy vault solutions. For merchants who want a modern tokenisation layer decoupled from any single PSP, it's a credible option.
Anti-Fraud Orchestration
Gr4vy integrates fraud detection tools directly into payment flows: merchants can layer multiple fraud providers into routing logic. This keeps fraud decisioning and payment routing in the same workflow rather than bolting on separate fraud tools.
Where Shuttle Wins
Built for Platforms, Not Merchants
Gr4vy's core product is orchestration for a merchant optimising its own payment stack, and Gr4vy for Platforms extends it to sub-merchants. Shuttle is platform-facing by design: it serves software companies that embed payments for their merchants.
White-Label Merchant Tools
Shuttle provides pre-built, white-label:
Merchant onboarding: branded signup flows for your merchants
Checkout components: payment forms branded as your platform
Management portal: transaction views, refund processing, payment settings under your brand
Multi-Channel Coverage
Shuttle covers these payment channels through one integration:
Voice payments: PCI-compliant DTMF capture, agent-assisted payments, AI voice agent processing
Payment links: Branded links sent via SMS, email, or messaging
AI agent payments: Card capture through AI voice and chat agents
Chat payments: Secure payment within messaging interfaces
The clearest difference is the phone: Shuttle captures card details inside a live call, for a person or an AI agent.
Compliance Breadth
Both hold PCI DSS Level 1. Shuttle also holds ISO 27001 and SOC 2 certifications, important for platforms in regulated industries where these are procurement requirements. Check Gr4vy’s current certifications directly.
Enterprise Track Record
Shuttle has been operating in regulated payment environments with enterprise compliance certifications, a consideration for platforms evaluating production readiness and long-term vendor stability.
The Platform vs Merchant Question
The decision follows the same logic as every orchestration comparison: Are you a merchant or a platform?
If you're a merchant who wants a modern, cloud-native way to manage multiple PSPs, with dedicated infrastructure, smart routing, and a clean developer experience, Gr4vy is built for you.
If you're a platform that needs to embed payments for your merchants, with white-label tools and voice and multi-channel support on each merchant's own compatible gateway, Shuttle is built for you.
Gr4vy's cloud-native approach is genuinely modern, and its platforms product brings orchestration to sub-merchants. Shuttle's difference is the channel mix: card capture inside the call alongside links and checkout, on one integration.
When to Choose Gr4vy
You're a merchant (not a platform) who wants modern, cloud-native payment orchestration
You want a dedicated cloud instance for data isolation or residency requirements
You want a no-code flow builder for routing and fraud logic
You value modern architecture: purpose-built cloud-native vs legacy infrastructure
You want a modern vault without the baggage of older orchestration platforms
When to Choose Shuttle
You're a platform embedding payments for your merchants
Your merchants need PSP flexibility: different merchants using different gateways
You need white-label tools: onboarding, checkout, portal, all platform-branded
You need multi-channel payments: voice, links, chat, or AI agent support
You want one integration across every PSP
You're a CCaaS provider, insurance platform, or AI agent company needing embedded payment infrastructure
FAQ
Is Gr4vy a competitor to Shuttle? In part. Both connect to multiple PSPs, and Gr4vy for Platforms serves sub-merchants too. Gr4vy is primarily an orchestration layer that competes with Spreedly and Primer. Shuttle competes with platform payment solutions such as Stripe Connect and Adyen for Platforms, and adds card capture inside voice calls.
How does Gr4vy compare to Spreedly and Primer? Gr4vy positions itself as a modern, cloud-native orchestration platform, and its dedicated-instance deployment model is a differentiator. All three are orchestration tools at their core; Gr4vy also sells a platforms product.
Does Gr4vy's dedicated cloud instance matter for platforms? It's a strong feature for merchants with data residency needs. But for platforms, the question is different: you need multi-tenant infrastructure that serves many merchants, not a dedicated instance for one merchant. The deployment model that differentiates Gr4vy from Spreedly isn't relevant to the platform use case.
