Reddit Inc.

One of the top social advertising platforms in the US, uniquely positioned around interest-based community targeting and authentic user engagement

Reddit Inc. is a social media and online community platform that hosts thousands of topic-specific communities called subreddits, where users share content, vote on posts, and engage in discussions. Founded in 2005, Reddit has grown into one of the most visited websites in the world, with hundreds of millions of monthly active users spanning virtually every interest category imaginable. Its unique community-driven structure creates highly contextual, interest-based audience segments that are particularly valuable for targeted advertising. In the AdTech ecosystem, Reddit operates a self-serve and managed advertising platform that allows brands to reach users through various ad formats including Promoted Posts, Video Ads, Conversation Ads, and Takeovers. Reddit's advertising proposition centers on the authenticity and depth of engagement within its communities — users on Reddit are often in a research or discovery mindset, making them receptive to relevant brand messaging. The platform has invested heavily in its advertising infrastructure, including improved targeting capabilities, brand safety tools, and measurement solutions. Reddit went public on the New York Stock Exchange in March 2024, marking a significant milestone in its evolution from a niche forum site to a mainstream advertising platform. The company has also expanded its revenue streams through data licensing agreements — most notably a landmark deal with Google — allowing AI companies to train large language models on Reddit's vast repository of human-generated content. This positions Reddit uniquely at the intersection of social media, community intelligence, and AI data infrastructure.
