• A new wave of startups are trying to change the digital advertising industry.
• They're pitching new tech for cookieless ads, streaming TV, and influencer marketing.
• Here are 24 pitch decks that startups have used to attract investors.

After years of challenges securing funding, a new wave of advertising startups is raising millions.

These companies aim to solve the industry's big challenges, such as the death of third-party cookies, the shift from linear to streaming TV budgets, and helping advertisers run influencer marketing campaigns.

But unlike their predecessors, these new startups are significantly smaller and more focused than many of the early digital advertising companies that raised hundreds of millions of dollars, like MediaMath and Millennial Media.

Business Insider spoke with founders about how they convinced investors to buy into their companies.

For example, ID5 sells to brands and publishers an ID product that doesn't use third-party cookies. Companies like Vibe, Telly, and TVScientific aim to shake up how advertisers buy and measure TV ads. Other companies like FreshSound and Catch+Release are focused on helping marketers license media for use in their campaigns.
