Welcome to 2026, where the line between shitposting and securities filings gets blurrier by the day. Engram Lab, a company building memory and personalization layers for AI models, posted what it described as an “Initial Public Offering” announcement on X on June 23. The NYSE responded with support. The only problem: there’s no S-1 filing, no actual listing, and the company remains very much private. ## A $600 million joke with a straight face Engram Lab just raised $98 million in funding at a $600 million valuation. The round was led by General Catalyst, Kleiner Perkins, and Sequoia Capital. Andrej Karpathy, the former Tesla AI director and OpenAI researcher, also participated. Engram Lab was founded in 2025 by a team that includes CEO Dan Biderman and Stanford professor Scott Linderman. The founding team brings backgrounds in neuroscience and AI, which tracks given the company’s core focus: making AI models better at remembering things and managing context without burning through massive amounts of compute. The company currently employs around 13 people. That means Engram Lab’s valuation works out to roughly $46 million per employee. ## What Engram Lab actually does Engram Lab builds memory and personalization layers that sit on top of existing AI models. Every time you start a new conversation with an AI chatbot, it’s essentially meeting you for the first time. Engram Lab wants to fix that by giving an AI a notebook it can actually reference, rather than forcing it to re-read everything from scratch each time. This reduces computational costs and improves the quality of responses, especially in enterprise settings where context matters. ## Why the NYSE played along, and what it signals Stock exchanges have been actively courting tech and AI companies for future listings. The competition between NYSE and Nasdaq for high-profile IPOs is intense, and both exchanges have expanded their social media presence to build relationships with founders early. A playful congratulatory response costs the NYSE nothing and builds goodwill with a company that, given its trajectory and investor backing, could plausibly go public in the future. The participation of General Catalyst, Kleiner Perkins, Sequoia, and Karpathy represents a concentration of investors that rarely converges on a single early-stage company. The fact that Engram Lab remains private means retail investors can’t directly participate yet. Whether Engram Lab eventually files a real S-1 is anyone’s guess. But at $600 million and growing, the gap between satirical IPO and actual IPO may be narrower than the joke implies. **Disclosure:** This article was edited by Editorial Team.
