State of the Market: Scale, Concentration, and Channel Shifts

The StartUs Insights Discovery Platform highlights 5591 startups from a broader base of 800K+ companies. The industry grew by 2.09% yearly. This development fits with what analysts estimate to happen around the world: the advertising market will be worth USD 995 billion by 2033.

While long-term conservative estimates look toward 2033 for a milestone, near-term forecasts are more bullish. Magna forecasts global advertising revenue to reach USD 990 billion as early as 2025.

The broader market reflects this growth momentum. Q1 2025 deal activity in AdTech and MarTech increased by 33% year-over-year (YoY). Total deal counts reached 116 in that quarter alone, driven by a consolidation wave where larger platforms acquired specialized startups.

In mature markets like the UK, agency headcount grew by 0.6% in 2024 to reach 26 787 employees in IPA member agencies. Simultaneously, staff turnover rates in major hubs dropped significantly from ~31% in 2023 to 24.1% in 2024.

The advertising business is growing at a rate of 2.09% each year. While our data reflects a surging startup ecosystem, global ad revenue is growing at a more mature pace. Digital formats are still driving the industry. In 2024, digital channels accounted for 72.7% of worldwide ad investment.

Further, Simpler Media Group reported a 27.8% YoY increase in the number of martech solutions. The number of tools jumped to 14 106. This was driven largely by a 77% surge in new AI-native applications.

At the same time, the broader martech market now features 15 384 solutions according to Scott Brinker and Frans Riemersma’s The State of Martech 2025 report.
