You've scaled your revenue. Your operations haven't kept up.

Most fast-growing DTC brands reach a point where spreadsheets stop working. 16 tabs, copy-pasted supplier data, version chaos. One missed reorder, one stockout before a peak, and suddenly revenue leaks, cash gets stuck, and the team is firefighting instead of growing. Rewize is the inventory forecasting and planning layer your stack is missing. It connects your channels, learns your demand patterns, and tells you exactly what to buy, when, and from whom, for all your SKUs.

Your current situation

  • No single view: data lives in spreadsheets and silos.
  • Reorders and safety stock are guesswork.
  • Mistakes happen more often and get more costly.

With Rewize

  • One demand view from channels and sales history.
  • What to buy, when, and from whom, without guesswork.
  • A planning layer on your stack, no rip-and-replace.

What our customers say

Built by operators who lived the problem.

Rewize was built by founders who ran fast-growing eCommerce brands. We'd spend nights buried in spreadsheets, guessing reorder quantities, and fretting over stockouts. We nearly went bankrupt due to overstocking on 3 separate occasions. We built Rewize to remove that friction, not to create another tool.

We were buying on gut feel and paying for it in stockouts and dead stock. I never want to plan a season that way again.

Thijs Roelofs

Co-founder & CEO
