Instinct AI Assistant Raises $350 Million at $2.5 Billion Valuation Despite Privacy Concerns

Viral AI startup Instinct has raised $350 million at a $2.5 billion valuation

Instinct, a startup founded only last year and helmed by a 23-year-old, has managed to ride the wave of AI enthusiasm toward a gargantuan valuation over the course of the summer. The company, which offers an AI assistant that has inspired enthusiasm among its early users, 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, which is offered by the company Spear Street Technology and led by founder Noah Shinn, is an agent that the company says can efficiently organize your life. Users connect it to their apps and devices and can communicate with it via texts and calls. "I'm thrilled with everything our early users are doing with Instinct," Shinn wrote in a tweet on Wednesday. "They've told us they've planned cross-country road trips, bought weekly groceries and concert tickets, and cancelled hundreds of dollars of subscriptions. Someone's even planning their wedding with Instinct." Instinct, which rocks a decidedly lo-fi website, is currently in private beta, but it has already inspired a certain amount of controversy due to privacy concerns. Online, users have worried about the overly generous permissions that the app requires as well as its terms of use that has disturbed some users because of their invasive potential.

Consumer-focused AI assistant startup Instinct reportedly raising $250M

Consumer-focused AI assistant startup Instinct reportedly raising $250M Instinct, the developer of an artificial intelligence assistant popular among Silicon Valley tech workers, is reportedly raising $250 million in funding. The company told the Wall Street Journal on Wednesday that the round is being co-led by Index Ventures and Benchmark. It's set to value Instinct at $2.5 billion. The startup previously raised $100 million from a consortium that included Conviction Partners and Greenoaks. Instinct, officially Spear Street Technology Inc., is led by Chief Executive Officer Noah Shinn. He previously worked at Sierra Inc., an AI startup headed by former OpenAI Group PBC board chair Bret Taylor. Instinct entered the consumer AI scene in February by making its assistant available via an invite-only private beta program. Consumers can set up Instinct by connecting it to applications such as Gmail. The assistant can manage the user's calendar, send emails and perform related tasks. It's also capable of automating more complex multi-step workflows. Shinn told the Journal that one early adopter used Instinct to buy a house. It's unclear what AI model powers the assistant. One possibility is that Instinct used the $100 million it had raised prior to today's round to build a custom neural network. The most cost-efficient way to build a custom AI is to fine-tune, or customize, an existing open-source large language model. That customization is usually done by providing the LLM with additional training data. Many AI services use not one but several models under the hood. They send complex requests to a frontier LLM while simpler prompts are processed by a less capable, more cost-efficient algorithm. Instinct's data collection policies have drawn scrutiny from some early adopters. According to the Journal, the company's terms of service enable it to train its AI models on user data. Shinn told the publication that his team is working to address users' cybersecurity concerns. Instinct is the latest in a series of viral AI agents to have emerged over the past two years. The first was Manus, which made its debut last March. It was followed by OpenClaw, a desktop-based AI agent that supports LLMs from more than a half-dozen providers. Gaining access to Instinct's private beta program requires users to join a waitlist or receive an invitation from an existing customer. Startup Superhuman Inc., the developer of a popular email client, used the invite-only access model to great effect as part of its marketing strategy. The company's waitlist at one point had 180,000 users. Superhuman was acquired by Grammarly Inc. last year. Today's report didn't specify how Instinct will use its newly raised capital. The company's one-page website hints that it plans to buy additional computing infrastructure.

Instinct Nears $2.5 Billion Valuation as AI Assistants Take Over Daily Chores | PYMNTS.com

Instinct was founded in 2025 and has raised $350 million, including the new round. The company began testing its AI assistant in private beta in February and experienced a surge in popularity earlier this month as users posted about its capabilities, according to the report. Users of Instinct can communicate with the AI bot via phone call or text and ask it to perform tasks such as responding to email, managing calendars, booking a ride to the airport, shopping for insurance or finding apartment rentals, the report said. Some users have raised concerns about security and privacy because they must give Instinct access to sensitive personal data and because the company's terms allow it to train its AI models on user data, per the report. Shinn said in the report that the company takes these concerns seriously and that it has stopped the agent from taking some actions that earlier versions of Instinct were able to take. According to Instinct's website, the personal assistant connects to the user's email, messaging, screen, audio, location and more; uses a phone and computer as interfaces; and is trained to understand and handle everyday tasks. Shinn said in a Wednesday post on X that the personal agent is available in an invitation-only beta program while the company secures more compute. "I'm thrilled with everything our early users are doing with Instinct," Shinn said. "They've told us they've planned cross-country road trips, bought weekly groceries and concert tickets, and cancelled hundreds of dollars of subscriptions. Someone's even planning their wedding with Instinct." The PYMNTS Intelligence report "The New AI Handshake: Data Shows When Consumers Want Help and When They Want Control" found that while consumers still use AI for writing, search and research, the next growth wave is forming around repeatable daily chores such as meals, shopping, reminders, budgeting, household logistics and personal planning.
