A 23-Year-Old's AI Assistant Just Raised $250 Million — But Users Are Already Worried About Privacy
A startup called Instinct has raised $250 million in new funding, bringing its total to $350 million. Investors now value the company at $2.5 billion, according to the Wall Street Journal (WSJ).
The funding round was co-led by two well-known venture capital firms, Index Ventures and Benchmark, with another firm called Conviction Partners also joining as an investor (TechCrunch, WSJ).
Instinct is an AI assistant — a software program designed to help people with everyday digital tasks. The company behind it, Spear Street Technology, was founded in 2025 by Noah Shinn, who is 23 years old.
The product is still in private beta. That means only a small, invited group of people are currently testing it. It is not yet available to the general public.
What makes this funding round unusual is the speed. A company founded roughly a year ago, still in private testing, commanding a $2.5 billion valuation requires either extraordinary early traction or extraordinary investor confidence in the founder's vision. Both Index Ventures and Benchmark have strong track records of backing successful consumer technology companies, and their joint leadership of this round sends a signal that is hard to ignore, especially in a funding environment that has otherwise tightened considerably for early-stage AI companies.
There is already a counterweight to that enthusiasm. Instinct's AI assistant has raised privacy and security concerns among users (TechCrunch). The specifics of those concerns have not been detailed in the reporting available, but the fact that they are surfacing during private testing, before the general public can access the product, is worth noting. AI assistants that help people across their digital lives need deep access to personal data, messages, and work habits. That means there are simply more ways for something to go wrong compared with AI tools that do a single, narrow task. When privacy concerns appear before a product reaches wide release, they tend to grow louder rather than quieter as more people start using it.
The broader context is that the AI assistant category has become one of the most competitively and financially contested spaces in technology. Large companies like Google, Microsoft, and Apple have already built assistants into their operating systems, productivity apps, and search engines. For a startup like Instinct to justify a $2.5 billion valuation at this stage, it would need to offer something in capability, user experience, or data handling that those large companies cannot easily copy. Privacy concerns at this early stage work directly against the trust that any AI assistant needs to be widely adopted.
Conviction Partners' participation adds another piece of the picture. The firm has been an active early-stage AI investor, and its involvement alongside two firms of Benchmark's and Index's stature suggests the investor base sees something in Instinct's technology or business approach that the public reporting has not yet fully captured.
Shinn's age and founding timeline place Instinct in a lineage of young-founder AI companies that have attracted outsized capital. The track record for such companies is mixed. Some have turned early momentum into lasting businesses; others have stumbled on execution, governance, or the gap between the promise of a beta product and the reliability needed at full scale. Which path Instinct takes is not knowable from a funding round alone.
What is concretely knowable today: a 23-year-old founder has built an AI assistant that is still in private testing and has attracted $350 million in total funding from top-tier investors at a $2.5 billion valuation, while simultaneously drawing privacy and security questions from the users who have tried it. Those two facts coexist, and both will shape what comes next.
