The next customer at your door might not be human

Most businesses have spent twenty years designing their online presence for two kinds of visitor: people and search engines. A run of announcements from Meta this week points to a third kind turning up sooner than expected: AI agents doing errands for the people who own them.

How fast this is moving

Muse, Meta's consumer agent, landed on iPad only weeks after its iPhone release. For comparison, Instagram users waited roughly a decade and a half for a proper iPad app. AppMagic data shows that the app has had a staggering 7,522,631 downloads since its launch in September, and people are already using it to make purchases, arrange appointments and chase customer service problems, sometimes through official integrations and sometimes by operating a company's website directly. That's mainstream adoption, not an experiment.

The case against blocking

Plenty of companies have reacted by shutting agents out. Their concerns are reasonable: unpredictable traffic, misuse, legal exposure, and the fear of losing their direct relationship with the customer. Meta's response is that an agent doesn't wander in uninvited. It arrives because a person has already decided to buy from you, book with you or get help from you. Refuse the agent, and from that person's point of view, your business simply didn't work for them.

Meta says Muse checks itself against two principles before acting online. One is what it calls the "one honest person" test, which asks whether a fair-minded human doing the task manually would behave the same way and at the same volume. The other asks what would happen if every user sent the same instruction at once. A single fan grabbing extra copies of a limited-edition drop is irritating; millions of agents doing it would make the drop pointless. Anything significant, such as logging in, confirming a booking or spending money, needs the user's sign-off first. 

A shared rulebook for agents

The more significant development is the Personal Agent Protocol, an open standard Meta is building with Sierra alongside Genesys, NiCE, Decagon, Rocket, Shopify, Stripe and Walmart. It's designed to settle three things: how an agent proves whose behalf it's acting on, how a business directs agents to the routes and APIs it would prefer them to use, and how a personal agent can deal directly with a company's own AI rather than clicking through a site meant for people.

Meta compares the ambition to email, a system that works because it runs on common conventions no single company controls. Whether that comparison holds will come down to adoption, not announcements.

What this means for app businesses

Muse doesn't need to open your app to get something done. It works through its own cloud browser or through connectors, and Meta has already added integrations for products like Asana, Canva, Dropbox, Figma, Notion and Zoom. For the apps that aren't connected, the agent will try the web route instead, or move on to a competitor that's easier to work with.

That challenges some of the assumptions the app economy is built on. If a user's task gets completed without them ever launching your app, what happens to your engagement numbers, your in-app upsells or the ad impressions that fund a free tier? If discovery shifts from app store listings to an agent's list of available connectors, how do you make sure you're on it? And when an agent can talk directly to your systems, do you have the APIs, permissions and policies in place to let it in on your terms?

The apps that do well in this shift will be the ones that treat agents as a new distribution channel rather than a threat to their front end.

The bottom line

Agents are coming regardless of whether businesses invite them. The real decision is whether you're set up to recognise them when they arrive. Companies that define how agents can engage, instead of refusing them by default, stand to win the customers their competitors keep locking out.

The way customers reach businesses is being rebuilt. Now is the time to decide what your version of the front door looks like.
