About Undercut

Undercut is built and run by a solo founder, in the open, in 2026. It exists because of a pattern in every conversation with eBay sellers: the tools that automate pricing are bloated, expensive, and — worst of all — sellers fear they'll race prices to the bottom while they sleep.

So Undercut is built backwards from that fear. The per-item hard floor is the centerpiece, not a buried setting: the repricer beats your lowest competitor automatically, 24/7, but it will never cross the minimum you set — cost + fees + the margin you decide. Win the sale. Keep the margin. Sleep.

Today Undercut is live: one-click eBay connection, automatic listing import, floor-first repricing with AI-tuned aggressiveness on higher plans, and a log of every price change it makes. It's early — which is exactly why joining now is good: every signup today is a founding user with direct email access to the founder and founding pricing locked in.
