Instinct, a startup founded last year and led by a 23-year-old, managed to ride the wave of enthusiasm for AI to a gigantic valuation over the course of the summer. The company, which offers an artificial intelligence assistant that has inspired enthusiasm among its early adopters, told the Wall Street Journal on Wednesday that it had raised $250 million in a recent Series B funding round. That new round brings the company’s total funding to $350 million and gives the startup a valuation of $2.5 billion. That new funding round was co-led by Index Ventures and Benchmark, the Journal reported. Instinct, offered by the company Spear Street Technology and led by founder Noah Shinn, is an agent that the company claims can organize your life efficiently. Users connect it to their apps and devices and can communicate with it via text messages and calls. “I’m thrilled with everything our early adopters are doing with Instinct,” Shinn wrote in a tweet on Wednesday. “They told us they planned cross-country road trips, bought weekly groceries and concert tickets, and canceled hundreds of dollars in subscriptions. Someone is even planning their wedding with Instinct.” Instinct, which is a decidedly lo-fi website, is currently in private beta, but has already inspired some controversy due to privacy concerns. Online, users have been concerned about the overly generous permissions the app requires, as well as its terms of use, which have upset some users due to its invasive potential.
