Best AdTech Companies in Poland
The 57 best AdTech companies in Poland in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Cosmose.
Poland's AdTech scene gets ranked here by disclosed equity funding and recent funding momentum, giving you a clear read on which of the 57 tracked companies have actually put capital on the table. Total disclosed funding across the cohort sits at $27M, and Cosmose accounts for essentially all of it. That concentration tells you something real about where conviction has landed.
The global AdTech market was valued at roughly $783.5B in 2024 and is forecast to reach $1,496.2B by 2030, a 14.3% CAGR according to MarketsandMarkets. AI-driven targeting and omnichannel strategies are pulling that growth, and data privacy regulation is reshaping how Polish players build their stacks. So what does it mean that names like Rtb House and Adlook carry zero disclosed funding? It means bootstrapped or privately held, not inactive. I'd watch both. Xevin Investments and Movens Capital are the most visible backers in this cohort, and the hot themes right now, predictive analytics marketing and playable ads, suggest the next funding stories here won't look like the last ones.
