Core Data Persistence: Complete Guide for App Founders in 2026

Stage-Appropriate Choices

Pre-PMF: validate cheap. Post-traction: ship production with fixed-price agency.

• Idea stage: interviews + landing page
• Pre-seed: prototype + agency MVP
• Seed+: hire in-house for v2 features

Scope Discipline

MoSCoW prioritization prevents the #1 MVP failure: shipping too much too late.

• Must: one job-to-be-done
• Should: onboarding polish
• Could: referrals, AI
• Won't (v1): enterprise features

Partner Selection

Fixed-price, milestone-based agencies reduce founder anxiety vs hourly unknowns.

• Entry packages from $3,460
• TestFlight before final payment
• References in your vertical

Launch Checklist

Store assets, privacy policy, analytics, support channel—before paid ads.

• Crash reporting live
• Key funnel events instrumented
• Review prompt timing planned
