Most hardware startups don't fail because the product is bad.
They fail because the founder never stopped to ask the right questions.
Who actually has this problem — and will pay to solve it? Do the unit economics work at any realistic volume? Who makes it, where, and what happens when that relationship breaks? What certifications do you need before you can legally sell a single unit?
These aren't nice-to-have questions. They're the ones that determine whether your company survives the first two years.
The Hardware Startup Canvas exists to force those questions early — before you've burned through your runway finding out the hard way.
