Summary

PM interview at Meta with a strategy question about payments. Just the one question from what I can tell, but it was a meaty one that required actually thinking through build vs. partner tradeoffs in a real product context.

Q1

Imagine Meta Pay doesn't exist. Would you recommend Meta build a payment solution in-house or partner with an external provider? Walk through your reasoning.

I went straight to the build side because Meta has the scale and the data, but I realized midway through I hadn't actually argued against it.

Suggested Approach

Start by clarifying the strategic objective—why Meta would need a payment solution—and then evaluate build vs. partner against criteria like speed, control, cost, and strategic fit. Recommend a hybrid approach: partner for immediate needs while building core capabilities in-house over time, and justify with trade-offs and risks.

Pro tip: Acknowledge that Meta's core competency is not payments, but owning the payment layer could unlock valuable data and reduce dependency; however, regulatory and fraud complexities often make partnering the pragmatic first step.

1. Clarify the goal

Define what problem the payment solution solves: is it for ads, commerce, peer-to-peer transfers, or a new revenue stream? The answer shapes the build vs. partner decision.

2. Evaluate strategic fit

Assess whether payments are core to Meta's long-term strategy. If payments enable unique experiences or data advantages, building may be worth it; otherwise, partnering is likely better.

3. Compare build vs. partner

Analyze trade-offs: build offers control, customization, and long-term cost savings but requires significant investment, time, and regulatory expertise; partner offers speed, compliance, and scalability but reduces control and margins.

4. Consider a hybrid approach

Propose a phased strategy: partner initially to launch quickly and learn, while investing in building core components (e.g., fraud detection, user experience) to eventually bring more in-house.

5. Recommend and mitigate risks

Make a clear recommendation based on the analysis, and outline key risks (e.g., regulatory, dependency, cost) with mitigation plans.

Key Points to Mention

  • Meta's core competencies: social graph, scale, and data—not payments infrastructure.
  • Regulatory and compliance complexity (e.g., money transmitter licenses, KYC/AML) favors partnering initially.
  • Strategic value of owning payment data and user experience for commerce and ads.
  • Cost and time to build vs. partner: build is capital-intensive and slow; partner is faster but may have higher per-transaction fees.
  • Precedents: Meta's past attempts (e.g., Libra/Diem, WhatsApp Pay) show challenges in payments.
  • Hybrid model: partner for back-end processing while building front-end experience and value-added services.
