About Colossus SSP

Colossus SSP is driven by a mission to ensure that the programmatic market is equitable to all publishers, advertisers, and communities.

Founded in 2012, we quickly attracted an impressive roster of brands, publishers, and DSPs. In just seven years we’ve grown from a strappy startup to one of just nine Black-owned businesses to go public. We’re also the only minority-owned SSP that is also publicly traded. As a profitable, publicly-traded company, we are well-positioned to capitalize on the rapidly evolving digital advertising market. Our accelerated organic growth and established operational playbook pave the way for continued success going forward.

We believe the market will succeed best when every publisher regardless of size, has the opportunity to get a fair share of the advertiser’s budget. All too often publishers are excluded from the programmatic market due to inventory minimums, even though they have valuable audiences that many brands are keen to reach. Like all of DDH’s brands, Colossus SSP is committed to the success of our publishers and buyers. We work with publishers to provide them both the tools and knowledge they need to thrive in the market. And we take the time to understand the buyer’s goals and KPIs so that we can curate bespoke marketplaces for their campaigns.

As a top-performing diverse-owned supplier, we play a crucial role in helping brands, agencies, and consultancy partners achieve their social diversity, equity, and inclusion (DEI) objectives while staying within their budget. We take pride in being the ninth black-owned company to go public in the United States.
