Build vs. Buy is the wrong question.
Ask this instead:
Every founder asks: Should we build or buy? Better question: Should we care?
Auth? Buy. (Clerk, Supabase) Payments? Buy. (Stripe) Email? Buy. (Resend) Analytics? Buy. (PostHog)
Founders love to argue about vendor lock-in. Saving money at scale.
Newsflash: You don't have scale. You don't have money. You have zero users and a burn rate.
Founders waste months building features that:
→ Already exist
→ Are not differentiating
→ Will never be better than existing solutions
→ Distract from actual product
Your competitive advantage is NOT your auth system. It is your unique value proposition.
Build that. Buy everything else.
