Back in October I wrote about Agentic AI and said the technology running marketing for the world's biggest brands would be knocking on your door sooner than you think.
Ten days ago, the knock got louder.
Hightouch, a company most business owners have never heard of, raised $150 million at a $2.75 billion valuation to build AI agents that run marketing on their own. Not assist marketers. Run marketing. Researching customers, creating personalised propositions, campaigns, picking the moment and the channel, learning from every send, thousands of times a day, without a human pressing Go.
Their customers are DraftKings, Domino's and Spotify. So you might be thinking this has nothing to do with a business your size.
That is exactly the thinking that will catch you out.
What just happened, in plain English
Hightouch made its name helping big companies organise their customer data. Useful, but not headline news.
What earned them $150 million from Goldman Sachs and Bain Capital Ventures is what they are building next: a platform where AI agents do the marketing work themselves. The agents watch customer behaviour around the clock, spot opportunities, create on-brand content and propositions, choose who to contact, when, and through which channel, then learn from the results and go again.
Investors do not put $150 million behind a maybe. This round, at this valuation, is the market saying autonomous AI marketing is not a future trend. It is the direction of travel, confirmed and funded.
One of Hightouch's own customers, a large financial services firm, reports producing ad creative 80% faster and replacing 60 manually built customer journeys with one self-learning system. A small team now does the work that used to take departments.
What this technology actually does
Strip away the jargon and it works like this.
Imagine a customer of yours, let's call him David. He downloaded a guide from your website six months ago, went quiet, and last week started visiting your pricing page. He also opened your last two emails, which he had been ignoring since spring.
A human might spot that, if they happened to be looking, on the right day, with time to act.
An AI agent never stops looking. It connects those signals instantly and decides David is warming up. It works out which product or service he is likely to be considering, spots what information he is still missing to make a decision, and crafts the message that fills that gap. It sends it at the time he usually reads his emails, then books the follow-up. If David responds, it learns. If he doesn't, it learns that too, reshaping every message that follows and homing in on what will convert. Multiply that by every contact in the database, every hour of every day.
That is what Domino's and Spotify are switching on right now.
"But this is enterprise tech. Why should I care?"
Because the threat to your business is not Hightouch. It is what flows downstream from it.
Big companies do not stay in their lane. When a national firm can run hyper-personalised, perfectly timed engagement at near zero marginal cost, expanding into smaller accounts stops being expensive and starts being automatic. The mid-market firms watching them will follow, as they always do. And the buyers in your market will get used to a standard of speed and relevance that resets their expectations of everyone, including you.
Here is the uncomfortable comparison. Right now, a typical SME takes days to follow up a new enquiry, if it follows up at all. The systems being funded today respond in minutes, with a message shaped by everything that buyer has done. When those two approaches compete for the same customer, the outcome is not in doubt.
You will not feel this next month. You will feel it over the next two to three years, one quietly lost deal at a time. The businesses that lose rarely know why.
The part nobody tells you
Now for the honest bit, and it is good news if you act on it.
This technology has a dependency the press releases gloss over: it only works on clean, connected data and a genuine understanding of how your customers buy. AI agents are only as good as the information they run on. Feed them fragmented CRMs, disconnected email tools and guesswork about your customer journey, and they will simply automate the mess. Faster, more expensive noise.
Most businesses, including plenty of enterprises, are nowhere near ready on that front. Gartner's own research shows the vast majority of marketing teams experimenting with AI agents have not got them into full production, precisely because the data foundations are harder than the demo suggests.
This is where smaller businesses hold a real advantage. You are closer to your customers. Your data is simpler. Your journeys are shorter. You can get your house in order in months, not years, and at a fraction of the cost.
What to actually do, starting now
You do not need AI agents. You need the foundations they will eventually run on, and those foundations pay for themselves long before any AI gets involved.
In practice that means one connected system, not a Frankenstack of disconnected tools, doing five jobs:
Capture every enquiry and lead in one place, from your website, email, social and events, so nothing leaks.
Profile each contact properly. Who are they, what do they care about, what have they actually done?
Engage based on behaviour, not blasts. The email someone gets after visiting your pricing page should not be the same one everyone gets on a Tuesday.
Nurture the ones who are not ready yet, automatically, so they buy from you when they are.
Convert when the signals say so, with sales seeing exactly what marketing knows, because it is one system, not two departments.
Here is the line worth remembering: you can build this for a few thousand pounds. You do not need access to a $2.75 billion platform to beat competitors who have done nothing. You need a connected system that knows your customers and acts on what they do. Our clients typically see a return inside six months, because better follow-up and better timing convert leads that were already being paid for and then wasted.
The cost of waiting
Every month without this in place, the same things happen. Enquiries go cold before anyone calls them. Warm leads get the wrong message or no message. Sales and marketing work from different versions of the truth.
That cost is invisible, which is why it feels safe to delay. It isn't. When this technology does trickle down, and it will, as all technology does, the businesses with clean data and a connected system will switch it on in weeks. Everyone else will be starting a two-year project while their competitors pull away.
The $150 million was not raised to help businesses like yours. Which is precisely why you should treat it as your early warning.
Get ready while it still counts as early
Being ready does not mean buying the biggest tool. It means understanding how your customers buy, and building a system around that. That is the work we do.
