Pre-seed and under $250K ARR, no-code or Firebase/Supabase is always the right answer — the $80K+ custom build delays PMF learning. Custom MVPs at $80K-$200K pay off after $500K ARR or when the product itself (not just the marketing) demands custom UX / performance — break-even vs a Bubble or Webflow MVP is typically month 14-20 because bugs, downtime, and scaling limits start costing deals. Above $1M ARR, custom is table-stakes for anything B2B (enterprise buyers need SSO + audit logs). Founders who delay custom builds past $1.5M ARR routinely hit compliance / performance walls that a full rebuild has to fix under pressure.
