I have a product idea. How do I evaluate whether it's actually worth building a brand around?
Screen every idea on three things before you source a single unit: can you acquire customers at a cost the product can support, does the buyer 'get it' fast enough to convert, and is there a believable path to repeat purchase or line extension. Then pressure-test the unit economics with real landed cost, shipping, packaging, returns, and ad spend, a fat sticker markup means nothing if fees eat it. If it survives that screen, validate demand with a small test before you commit inventory.

This is the checklist we'd hand anyone before they order their first batch: it splits evaluation into market-based criteria (size, competition, seasonality) and product-based criteria (margin, shipping, weight, scalability). It forces you to model real landed economics rather than getting seduced by a big-looking sticker markup.
The cleanest starting map for someone with no product yet, 17 concrete ways to surface ideas (solve your own pain, mine trends, find underserved niches, study competitor gaps) instead of staring at a blank page. It reframes 'what should I sell' as a research problem you can work, which is exactly the mindset a first-time D2C founder needs.
A short, no-hype reference on building a coherent product line, research trends, fulfil a unique need, target a demographic, that also explains why a unified line strengthens branding and simplifies marketing. Useful as a sanity check that your picks actually hang together as a brand, not a random shelf.
