our call
Start with Gr4vy — highest vibe code, weakest moat.
Alma
Alma is a regulated financial institution (ACPR licensed) that advances capital to merchants upfront while taking on consumer credit risk, fraud, and debt recovery. Building a checkout widget that splits payments via Stripe is trivial, but operating the underlying balance sheet, risk models, and legal debt collection cannot be replaced with code.
you can rebuild
- Checkout UI widget displaying 3x/4x or deferred payment breakdown options
- Automated customer notification emails and SMS payment schedules
- Merchant administration interface to view payment status and manually issue refunds
- Plugin integrations for Shopify, WooCommerce, PrestaShop, and Magento
- Scheduled charging engine utilizing off-session card tokens via payment gateways
what you lose
- 100% non-recourse merchant payouts upfront regardless of whether the buyer defaults
- Regulated EU payment institution and consumer credit licensing (ACPR compliance)
- Proprietary cross-merchant credit risk scoring algorithms and fraud mitigation
- Automated debt recovery operations and integration with European collection agencies
- Pre-approved consumer network with saved payment profiles across Alma merchants
real moats
- Regulated financial institution status and compliance framework across EU jurisdictions
- Capital reserves and balance sheet required to finance merchant payouts upfront
- Proprietary credit scoring models trained on millions of European consumer transactions

Gr4vy
Building a basic routing engine is straightforward, but replicating a secure, PCI-DSS Level 1 compliant token vault and dozens of gateway integrations requires continuous compliance audits and security overhead. Replacing Gr4vy with custom code introduces massive regulatory liability and integration maintenance burden.
you can rebuild
- Basic conditional payment routing rules engine
- Merchant admin dashboard for transaction monitoring
- Simple failover retry logic between two primary gateways
- Normalized unified checkout API schema
- Transaction metadata logging and analytics
what you lose
- PCI-DSS Level 1 compliant card data tokenization vault
- Out-of-the-box integrations with 50+ payment gateways and APMs
- Automatic 3D Secure 2 (3DS) / SCA step-up authentication handling
- Infrastructure isolation per merchant account
- Continuous API maintenance and compliance updates from payment providers
real moats
- PCI-DSS Level 1 certification and security liability absorption
- Broad pre-built integration catalog with PSPs, buy-now-pay-later (BNPL) providers, and fraud engines
- Universal token vaulting capable of cross-PSP token migration
