Gravity

Real-time contextual advertising platform for AI

Overview

Gravity provides an AI-native advertising network that monetizes LLM conversations by delivering contextual ads within AI responses with zero added latency. It offers Node.js and Python SDKs and a REST API so developers of AI tools can integrate advertising revenue streams into their platforms. The system analyzes conversations in real time to detect purchase intent and runs a live auction to surface native, sponsored suggestions relevant to the context. Advertisers manage campaigns via a self-serve platform and use measurement tools to track performance, with Gravity’s goal of subsidizing free or lower-cost AI access through ad revenue.

  • Gravity claims 14.3 million users gained free AI access through monetization.

What critics are saying

  • OpenAI launched ChatGPT Ads on 2026-09-16, compressing Gravity's platform advantage.

Gravity raised $38M. we flagged it at 36 followers, 92 days early.

Gravity raised $38M. Frontrun flagged it at 36 followers, 92 days early. tl;dr: Gravity raised $38M, with Lightspeed and Committed Capital co-leading the Series A and Caffeinated Capital leading the seed. frontrun flagged the company on may 6 2026, at 36 followers, 92 days before the announcement. the more interesting receipt: Lightspeed followed Gravity on july 30, seven days before announcing they co-led the round. who led Gravity's $38M? Gravity is building an ad network for AI: brands placing advertisements inside AI conversations, so consumer AI products can be free to use. the company says it has grown revenue for consumer AI applications by up to 14,722% and given 14.3 million people free access to AI products. the Series A was co-led by Lightspeed and Committed Capital. the seed was led by Caffeinated Capital with Basis Set, Haystack, Logos Fund, Grant Gordon and others. angels include Parker Harris, Alex Atallah, Scott Belsky, Guillermo Rauch, Ian Crosby, Nick Marwell and Sholto Douglas. flagged may 6 2026, announced august 6 2026. 92 days. Gravity entered the graph on may 6 off a single tracked follow, when the account had 36 followers. not 36 hundred. thirty six. it is still small today. at the time of the announcement the account sat at 355 followers, which means the entire round happened while the company was under 400 followers on X. this is the part that is hard to internalize until you watch it happen: a company can raise $38M from Lightspeed while its X account is smaller than your group chat. five tracked accounts followed Gravity between the flag and the news: | date | who followed | | may 6 2026 | CJ (the flag) | | june 15 2026 | Faraz Fatemi | | july 25 2026 | Nader Dabit | | july 26 2026 | JG | | july 30 2026 | Lightspeed Venture Partners | read that last row again. Lightspeed followed Gravity on july 30. on august 6 they announced they co-led the company's Series A. a fund following a company is not a press release, and it is not confidential either. it is a public action that happens while the deal is being worked, and it is visible to anyone who is watching the right accounts on the right day. seven days is not a long lead. it is long enough to make a call. this is the same shape as Sapiom and Osmo yesterday: tracked accounts accumulate on a company for months, and the announcement lands last. what makes Gravity a cleaner receipt is the follower count. at 36 followers there is no crowd to hide in, no trending page, no press. one tracked follow was the entire signal, and it was enough. the useful question is not "how did we know Gravity would raise." nobody knows that. the question is whether a company that the smart money is quietly following at 36 followers deserves ten minutes of your attention before it has a headline. Frontrun think the answer is obviously yes, and the follow graph is the cheapest way to find those companies at that size. this raise clears its receipt ledger's minimum lead with room to spare, so it joins the permanent record with its flag date. Gravity already raised. the useful list is the one where the round has not happened yet. frontrun watches the follow graphs of 2,000+ tracked venture investors on X and flags the companies they converge on, with a date, the morning it happens. see the signal this article is built on frontrun tracks the follow graphs of 2,000+ venture investors and flags companies months before rounds are announced. companies and founders surfaced on frontrun. curated, every week.
