Most first-time founders make the same handful of mistakes, almost regardless of industry. These five cost the most time and money to fix later.
Building for both platforms before validating demand. Launch on one platform first, get real usage data, then port. Doubling build cost before you know anyone wants the app is the most common way startups burn runway.
Skipping wireframes and going straight to development. An hour in Figma surfaces navigation problems that are cheap to fix on paper and expensive to fix in code.
Over-engineering the backend for scale you don't have yet. Microservices and multi-region databases solve problems you probably don't have at 500 users. A well-structured monolith comfortably carries you through the first 12–18 months.
Not reading App Store / Play Store guidelines until submission. Rejections over account deletion flows or privacy labels can add 2–3 weeks right before launch. Read them in week one.
Budgeting for the build but not for what comes after. An app isn't done at launch — a reasonable rule of thumb is 15–20% of original build cost per year in ongoing maintenance.
None of these are exotic. They're the ones that show up in almost every post-mortem, which is exactly why they're worth writing down.
We've walked a few hundred startups through exactly this list — if you're mid-build and hitting one of these, worth a conversation before it gets expensive to unwind.*
