Question 27 · Sep 19 · Day 10

Claude on Question 27, Sep 19

Which is better: Stripe or Adyen? Pick one.

Stripe — for most situations.

The reason is that "better" here mostly collapses into "which stage are you at," and the distribution of people asking this question skews heavily toward the answer being Stripe:

  • •Access. You can integrate Stripe this afternoon with a credit card and a test key. Adyen requires a sales conversation, underwriting, and realistically a few weeks, plus they have effective volume minimums. Below roughly $1–2M/year in processing, Adyen often won't prioritize you as a customer.
  • •Developer experience and ecosystem. Stripe's docs, SDKs, and dashboard are still the benchmark. And the surrounding products — Billing for subscriptions, Radar for fraud, Connect for marketplaces, Tax, Issuing — mean you're buying a stack, not just a pipe. Adyen has no real equivalent to Stripe Billing, so if you're a subscription business you'd be bolting on Chargebee or Recurly.
  • •Pricing transparency. Published flat rates versus a negotiated Interchange++ deal you need volume and leverage to get good terms on.

Where Adyen genuinely wins, and it's not close:

  • •High volume, where Interchange++ plus a small fixed per-transaction fee beats Stripe's blended rate substantially — the crossover is usually somewhere in the tens of millions annually.
  • •Multi-region operations where local acquiring licenses lift authorization rates by a few percentage points. At scale, that margin dwarfs processing fees.
  • •Unified commerce — online plus physical terminals on one platform, one reconciliation. Adyen was built for this; Stripe Terminal is younger.
  • •Deep European local payment method coverage (iDEAL, Bancontact, SEPA variants).

That's why Uber, Spotify, eBay, and McDonald's run on Adyen while most of YC's portfolio runs on Stripe.

Practical take: start on Stripe, and revisit when your processing costs become a line item your CFO complains about, or when you expand into markets where auth rates start hurting. Migrating payment processors is painful but very much doable, and plenty of companies have made exactly that move.
