Listowise — rewrites your eBay listings for Cassini.
Paste a listing, get a tuned version in 20 seconds. Title, item specifics, description — every change shows the signal it targets. 800+ real listings already sold through.
Software for the people actually running the store.
INVENTOWISE builds software for e-commerce sellers. Founded by an active eBay operator, every tool is tested on real inventory — our own store, Fiorivyfinds — before it ships to yours.
The best e-commerce software is built by people who still pack their own orders.
Every feature starts as a problem on our packing table. If we wouldn't use it, we don't ship it.
We show what worked and what didn't. Auto-revert when a tune drops rank. No vanity dashboards.
Small team, clear scope, no rush. One product, built right, before anything else. Honest timelines over roadmap theater.
One tool. Built on the packing table.
An operator-founded studio and the shop it runs on.

Founder of INVENTOWISE. Started it during breast cancer treatment, between infusions, building the tools to keep my eBay shop running on the days I couldn't lift a packing box. Every feature I ship, I use on my own shop first.
Fiorivyfinds
The shop that funds the studio. Victorian mourning lockets, mid-century silver, signed costume from the 50s. Hand-photographed on the kitchen counter, packed in tissue, shipped the same day. The proving ground for every Listowise feature.
We answer every email
from a packing table.
Operator with a hard problem? Want into Listowise early access? One address for all of it.
