At 23, Noah Shinn has already taken on Mark Zuckerberg. His invite-only AI assistant, Instinct, went viral among Silicon Valley insiders this summer and raised $250 million at a $2.5 billion valuation. The rapid rise of the startup has turned the college dropout into one of the hottest young founders in AI and placed his tiny company in direct competition with another company started by a dropout: Meta.
From Dorm Room to Venture Capital
Shinn dropped out of Northeastern University in 2023 after building a reputation as an AI wunderkind. He published high-level research papers on AI agents while still an undergraduate, a feat his professors described as rare and impressive. One professor noted that virtually zero students can write such papers on their own, and even fewer can do it without assistance. Another recalled him as a quiet student who preferred listening to speaking out, though he sent late-night emails full of detailed questions.
Shinn initially joined Sierra, a San Francisco-based customer support agent startup led by OpenAI chairman Bret Taylor. Taylor praised the young engineer, saying he was “an incredible engineer and entrepreneur” and grateful to have worked with him. After coauthoring several papers focused on improving agents’ ability to follow instructions and use tools, Shinn left Sierra in September 2025 to launch Instinct. The product soft-launched in the summer with a bare-bones website and no launch video, bucking the trend of flashy, polished startup reveals.

The core idea behind Instinct comes from a paper Shinn coauthored with MIT professor Ashwin Gopinath and four others in late 2022. The researchers developed a technique called Reflexion, which helps AI agents learn from their mistakes by remembering prior failures. That paper was presented at NeurIPS, one of the world’s most prestigious AI conferences. Arjun Guha, another of Shinn’s professors, said the basic technique is in a paper a second-year college student wrote before GPT-4. He described Shinn as having “immense drive and independence” and the ability to identify and execute on research questions on his own with little supervision.
Instinct’s growth captured a new phase of the AI race. After years of competing over which company could build the smartest chatbot, the battle shifted toward assistants that can actually get things done. These tools handle bookings, scheduling, and everyday errands with minimal prompting. Meta and other tech giants have enormous advantages in money, computing power, and distribution. Shinn’s ascent shows how quickly a small startup with the right product can still compete against Big Tech, even if the ultimate winner of this race is still unclear.
The New AI Assistant Race
Meta has become a significant rival for Instinct. Meta CEO Mark Zuckerberg promised to build a personal superintelligence last year. Internally, this project is known as Hatch. The company launched its AI agent, Muse, weeks after Instinct appeared. Zuckerberg stated that Meta had delayed Muse due to concerns about AI safety. That was also based on more practical concerns, such as ensuring Muse actually followed user instructions and didn’t, for example, buy products without users’ permission, a person familiar with the matter told Business Insider.
Meta holds a distinct advantage over Shinn’s small team. The tech giant possesses enormous computing power and vast amounts of cash. This financial strength helps maintain smooth operations for its products. The tech giant does have one key advantage: enormous amounts of computing power and cash that can keep its product running smoothly. Instinct, which is free and sometimes has significant lag due to high demand, depends on investor cash. Instinct is in talks to raise at a $10 billion valuation, according to a report from The Information.

Both Muse and Instinct are competing for dominance in the AI assistant market. The winner of this race remains unclear. Despite the odds, Shinn has already proven a major point. He showed that the next great AI assistant does not have to come from a big tech company. His startup has disrupted the field with a bare-bones website and no launch video. This direct competition with a billionaire’s project has captured the attention of the industry. Meta has taken notice of this success. Its AI chief, Alexa Wang, has mockingly dubbed Shinn’s startup “Insect” and posted that Muse is much faster — and “hotter.” Shinn responded with a smiley face.
Rival Investors Pull Out of Competing Startup
Noah Shinn reportedly persuaded his backers to stop funding a rival agent startup. Two of his biggest investors abruptly withdrew support from Town, a company backed by Andreessen Horowitz. The rival startup’s chief executive did not respond to requests for comment.
Reports indicate the investor pullout occurred after Shinn complained about the funding. Index Ventures and Conviction halted their investment in Town following the complaint. Instinct’s spokesperson declined to comment on the report regarding the investors.
