About

Operators first, engineers second.

We run marketplace businesses hands-on — and build the software we wished existed. That mix is the whole agency.

The SellerUp agency

SellerUp is a software agency that builds custom AI automation, AI agents and bespoke internal software for marketplace sellers — primarily on Amazon and Allegro, and also on Kaufland, Castorama and other European platforms.

Two lines of work: engineering — AI agents, workflow automation, custom analytics and internal platforms — and hands-on marketplace services: launches, product analytics, consulting, and team training.

We don’t sell subscriptions. We build systems that become part of your team, and we teach your people to run them without us.

The tone we work in: numbers over adjectives, honest go/no-go answers, and no “boilerplate proposals”.
