Launching 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. Edit any cell, then export a clean CSV ready for your PO. Built for brands that launch new styles regularly.
