See every featureLaunching a new product with zero sales history? DontGuess finds similar products in your existing Shopify catalog, combines them with your pre-launch signals like waitlist size and conversion rate, and generates a size-by-color buy plan you can defend. Every recommendation shows the comps used, the math behind it, and how constraints like MOQ and pack multiples were applied.

It tells you what will sell next, by SKU, channel and location, and what to buy to meet it.
