Kevel (formerly Adzerk) is an ad infrastructure company founded in 2010 by James Avery to provide API-first ad serving technology that allows digital platforms to build custom, first-party advertising networks rather than relying on third-party ad tech stacks like Google Ad Manager. The company was built on the thesis that publishers, marketplaces, and retail media operators needed programmatic-grade ad serving capabilities they could control, customize, and brand as their own — without the data leakage, opacity, and vendor lock-in associated with dominant ad tech platforms. Kevel's API architecture makes it uniquely suited for companies that need to embed advertising logic directly into their own product infrastructure.\n\nKevel's primary products include its core Ad Server APIs, which process 3 billion+ ad requests per day, and its Retail Media Cloud platform, which enables e-commerce companies and marketplaces to build sponsored product and display advertising businesses on top of their own shopper data. Customers include Edmunds for automotive listings ads, Klarna for commerce media, and Delivery Hero for restaurant and grocery sponsored placements — all examples of companies that needed ad serving infrastructure customized to non-standard inventory formats and audience contexts. The Retail Media Cloud positions Kevel at the center of the fastest-growing segment in digital advertising.\n\nKevel raised a $23 million Series C in March 2024, bringing total funding to approximately $42 million, to accelerate its retail media platform and expand its enterprise sales motion. The company has benefited significantly from the retail media wave — as Amazon's advertising business demonstrated the economics of first-party commerce data monetization, every major retailer and marketplace has sought to build comparable capabilities. Kevel's white-label approach allows these companies to move faster than building proprietary ad tech from scratch while maintaining full data ownership and control.
2024 Revenue: $23B (+42.8% YoY) | Users: 1.6B (+6.1%) | Ad Revenue: $23.6B in 2024, projected $33.1B in 2025 (+40.5%) | TikTok Shop: $1B+ monthly US sales | 77% revenue from advertising
TikTok is a short-form video social media platform developed by ByteDance, a Chinese technology company founded in 2012 and headquartered in Beijing, with TikTok's international operations based in Los Angeles and Singapore. Launched internationally in 2018 following the merger of ByteDance's Douyin platform with Musical.ly, TikTok was built around a fundamental insight: the dominant discovery mechanism for online video should be algorithmic interest graphs rather than social graphs. Its For You Page recommendation engine — trained on engagement signals including watch time, replays, shares, and comments — delivers a personalized infinite scroll of content that keeps users engaged far longer than follower-based feed architectures.\n\nTikTok's platform encompasses short-form video creation and consumption, live streaming, TikTok LIVE gifting and commerce, TikTok Shop (an integrated e-commerce marketplace launched in the US in 2023), and a creator monetization ecosystem. TikTok Shop surpassed $1 billion in monthly US sales, establishing TikTok as a meaningful e-commerce channel alongside traditional platforms. The platform's advertising business includes in-feed ads, branded hashtag challenges, TopView placements, and performance advertising tools for direct response marketers. TikTok for Business serves advertisers seeking to reach predominantly Gen Z and millennial audiences through native video formats.\n\nTikTok reported $23 billion in global revenue for 2024, up 42.8% year over year, with advertising revenue of $23.6 billion. The platform has 1.6 billion users globally and has become one of the most powerful cultural and commercial forces in digital media despite sustained regulatory scrutiny in the United States, where legislation requiring ByteDance to divest its US operations has created ongoing legal and operational uncertainty. TikTok's algorithmic discovery advantage, commerce integration, and creator ecosystem make it the defining social media platform of the current era.
