In September 2026, an AI assistant called Instinct became the most talked-about product launch in the sector. Not because of a technical demonstration, but because early users reported it actually did things: booking flights, buying tickets, canceling subscriptions, and managing emails, all from a WhatsApp or iMessage conversation.
Behind it is Noah Shinn, a 23-year-old developer who dropped out of college to found Spear Street Technology in San Francisco. The company has raised $350 million total (the latest Series B of $250 million, co-led by Benchmark and Index Ventures) and has a $2.5 billion valuation.
What Instinct does
Instinct has no app of its own. You use it through iMessage and WhatsApp: text it or call it, and it executes tasks on your behalf:
- Book transport: searches options, compares prices, completes the booking
- Buy tickets and products: from event tickets to grocery shopping
- Cancel subscriptions: accesses the service and manages the cancellation
- Send emails: drafts and sends from your account
- Task tracking: remembers pending items and notifies you of updates
The technical model is a cloud agent that maintains state between messages. If you ask it to book a trip in the morning and it needs more information, it asks in the afternoon. You don’t need to re-explain the context.
The interface is deliberately not new. There’s no app to learn. The company’s tagline is “no new interfaces”: Instinct uses applications you already have, the same way a human assistant would.
Why it matters to businesses
Instinct is a consumer product. It’s not enterprise SaaS. But its impact on businesses is direct and imminent, because it changes who interacts with your business.
Your customers will start using agents
When a user tells Instinct “book a table at restaurant X for Friday at 9pm,” the agent needs to interact with that restaurant’s reservation system. If the system is a web form designed for humans, the agent has to simulate clicks. If the restaurant has an API (or uses a service like Resy with an API), the reservation completes in seconds.
The same applies to:
- E-commerce: Is your checkout navigable by an AI agent? Is there an API to check stock, prices, and complete purchases?
- Customer support: Can your chatbot interact with another AI agent, or does it only work with humans?
- Bookings and appointments: Is your calendar accessible via API or does it require manual navigation?
Preparing your business for AI agents
Companies that capture value in this transition are those making their services machine-consumable:
- Open APIs: Endpoints to query products, availability, prices, and complete transactions without a human interface
- Structured data: Schema.org, JSON-LD, and metadata an agent can interpret without parsing HTML
- WhatsApp Business API: The channel where consumer agents like Instinct already operate
- Machine-readable confirmations: Confirmation emails with structured data the agent can process
If your business depends on customers browsing your website, filling forms, and reading confirmation emails, part of that interaction will migrate to AI agents over the next 12-18 months.
The personal AI assistant race
Instinct isn’t alone. Siri AI is expanding to Spanish, French, Japanese, Korean, and Portuguese with iOS 27.2. Meta has Muse. Google is integrating agent capabilities into Gemini. The trend is clear: every user will have access to an AI agent capable of acting on their behalf.
The difference between Instinct and Siri is that Instinct already acts (books, buys, cancels), while Siri remains a conversational assistant evolving toward agency. But the direction is the same.
Instinct vs enterprise AI assistant
Instinct acts for individual consumers. It tells the restaurant they want a table, the e-commerce store they want to buy, the streaming service they want to cancel.
An enterprise AI assistant does the opposite: it acts for your business. It serves your customers, answers their questions, manages support tickets, schedules meetings, and escalates complex cases to your team.
They’re opposite sides of the same coin. Your company needs to be prepared for both:
- Your own AI assistant that serves your customers (including those arriving through agents like Instinct)
- A technical infrastructure that allows external agents to interact with your services
What to do now
- Audit your channels: What percentage of your sales and bookings depends on human interaction with web forms? That’s your risk
- Evaluate your API: Do you have public endpoints for the operations an agent would need to execute?
- WhatsApp Business: If you’re not there, your competitors will be. Consumer agents operate there
- Schema.org: Ensure your pages have complete structured data
