How do I know people actually want this before I spend on tooling or bulk development?
The short answer
Sell it before you build it: take orders on a landing page, run a small ad budget against a mockup, or presell on Instagram with a real delivery date, and treat anything under ~2-3% conversion as a signal to rework the concept, not the ad. Tooling costs (injection moulds, custom packaging dies) are the least reversible spend in the whole business, every other decision can be undone faster and cheaper than a mould.

Founder-by-founder origin stories that repeatedly land on the same lesson: the first product was rough, shipped anyway, and got better in public.
Why we picked it
Written by an Indian private-label manufacturer, so the product-development steps are grounded in what an Indian factory can actually deliver, not a US playbook.
Why we picked it
Free, structured courses on product development and manufacturing logistics, a good weekend crash course before your first factory call.
