Software by merchants, for merchants.

The Marketplace Guys was founded in 2022 as a response to a very specific problem: we knew the challenges because we'd lived them ourselves. Listing suppressions in the middle of Prime Day, advertising budgets that explode overnight, resellers wrecking the Buy Box and prices. Out of that experience came an agency that doesn't want to consult but to execute operationally, a boutique. Deliberately not the biggest, but the one with the highest impact per client.

Working with brands like Fuchs, Alsitan, Happybrush, Ostmann, Blume Ideal, Vonmählen, AN-Commerce, Green Bean, Terapeak, anders, and Emma & Noah, we learned what D2C brands really need on marketplaces. In 2024, OTTO became our clients' second strategic marketplace. In 2026 we became an official OTTO Service Partner.

And that's exactly where the frustration started: the OTTO Partner Connect (OPC) is pure manual work for Sponsored Product Ads today. No bulk changes. No Excel-ready search-term report. No alerts on anomalies. Anyone running 30 OTTO campaigns for several brands clicks through hundreds of screens per optimization round. Much of what has been standard on Amazon for years is still missing in OPC today. The first third-party integrations on OTTO's Ads API target enterprise brands, not sellers and small agencies.

So we sat down and built internally what we needed, first only as an agency tool for our own OTTO accounts. Bulk bid changes, live connection to OTTO, automatic alerts on anomalies, search-term analysis in one click. After a year of internal use it was clear: we're not the only ones with this problem. That became Marginly as rentable software (SaaS), built by merchants who work with it every day themselves.
