Should Your MVP Be Mobile-First? The Framework I Use

Most founders default to web. Sometimes that's wrong. Here's how to make the platform decision before you commit resources.
One of the most expensive mistakes I see early-stage teams make is building on the wrong platform. Not wrong technology, wrong surface. Web vs mobile is a fundamental architectural decision that affects cost, timeline, and user acquisition.
The decision framework
Ask three questions: Where does your user complete the core workflow? Where does your user discover similar products today? What retention mechanism does your product need? If the answers point to mobile (location-based, habit-forming, notification-driven), go mobile-first. If they point to desktop (data-heavy, workflow tools, B2B), go web.
What this means for founders
There's no universal right answer. But there is a right answer for your specific product. Make this decision with your engineer in week one, not week six.
