Multi-channel listing sync for luxury fashion resellers - Oly

Oly is the platform that turns secondhand and "not new" inventory into revenue. We connect retailers, brands and resale businesses (think vintage stores) to the right secondhand marketplaces, automatically syncing listings across 12+ platforms including Vestiaire Collective, Grailed, Vinted, eBay and more. Bootstrapped to over six figure annual recurring revenue by solo founder.

Hey ProductHunt! 👋 I'm Paula, the founder of Oly.

Six years ago I started working in fashion trying to solve the problem of excess inventory. I built my first startup around upcycling — helping brands give unsold items a second life. But I quickly realized upcycling was hard to scale, and meanwhile the resale market was exploding.

So I pivoted. A fashion brand hired me to sell their "not new" inventory across resale platforms and I spent weeks doing it manually — listing each item one by one across Vinted, Vestiaire, Grailed, each with completely different requirements. No tool existed for this. Every solution was built for new products and completely broke down on secondhand complexity.

So I built Oly.

This is my second company, and the one I was always meant to build. I bootstrapped the entire way — reinvesting every euro of profit back into the business, staying lean, staying focused. That discipline is what got us to six figures with two people and zero marketing spend.

Today Oly manages over 1 million product listings, has processed $2M GMV in Q1, and we're growing 25% month on month — with zero paid acquisition. Grailed, the leading men's resale marketplace in the US, approached us to power their seller integrations.

We're just getting started. Would love to hear from anyone building in resale, fashion or circular economy — and of course any feedback on the product!

Syncing listings across so many platforms sounds useful,
but I wonder how well it handles differences between each marketplace.
