How to Restructure Sales and Marketing for AI Agents Before 2028?
Introduction
$15 trillion. 90% of B2B buying. AI agents are making purchasing decisions on their own. That is not a sci-fi prediction. That is where the data says we are headed, and fast.
Here is the line that should make every sales and marketing leader sit up. According to Gartner, by 2028, 90% of all B2B purchases will be handled by AI agents, channeling more than $15 trillion in spending through automated exchanges. Read that again. In a couple of years, the buyer on the other side of most of your deals will not be a person browsing your website or sitting through your demo. It will be an algorithm, comparing you against competitors on data alone, and deciding in seconds whether you make the shortlist.
That changes everything about how you sell and market. The glossy brochure, the charming sales rep, the clever ad campaign, none of that lands the same way when the decision-maker is a machine. And the businesses that wait until 2028 to react will already be too late. The smart move is to restructure sales and marketing for AI now, while you still have a head start.
So let me walk you through exactly what is changing, why it matters, and the practical steps to rebuild your sales and marketing engine for a world where agents do the buying.
What the $15 Trillion Shift Actually Means?
Let me put this prediction in plain terms, because the number is so big it almost feels abstract. Gartner is saying that within a few years, most business purchasing will not involve a human clicking “buy.” Instead, AI agents will research vendors, compare options, negotiate terms, and execute purchases, all on behalf of the companies that own them.
This is already starting. PwC found that 79% of companies are already adopting AI agents for tasks like procurement and vendor sourcing. Gartner’s own survey showed that 67% of B2B buyers now prefer a rep-free buying experience. Buyers no longer want to talk to your sales team. Increasingly, they want their agents to handle the whole thing.
And the people who study this shift are blunt about what it means. As one Kearney partner put it, the new storefront for your business is not your website or your sales rep. It is the algorithm that decides what your customer’s AI sees first.
If your business is not in that algorithm’s consideration set, you do not exist, no matter how good your product actually is. This is the exact shift we covered in detail in our deep dive on AI agents in B2B buying, and now it is time to talk about what you do on the selling side.
Why Your Old Sales and Marketing Playbook Breaks?
Here is the uncomfortable truth. Almost everything that won deals in the human era works differently, or not at all, when an agent is the buyer. Let me show you what breaks.
Brand storytelling loses its grip. Agents do not get moved by your mission statement or your beautiful design. They optimize for price, specs, availability, fulfillment speed, and verifiable data. The emotional layer of B2B selling mostly disappears from the agent’s decision.
Gated content stops working. For years, you traded a whitepaper for an email address. But agents will not fill out your lead form to get information. They expect to access it instantly. The whole “gate the content, capture the lead” model falls apart.
Your website stops being the destination. Buyers used to come to your site, explore, and convert. Now their agent pulls what it needs through data and APIs and never “visits” in the traditional sense. Your beautifully designed homepage might never get seen by the actual decision-maker.
Legacy metrics lose meaning. MQLs, page views, time on site, these were built for human behavior. When agents do the early research, these numbers stop telling you anything useful. What matters is whether you made the agent’s shortlist.
None of this means sales and marketing die. It means they have to be rebuilt around a new kind of buyer. Here is the shift at a glance:
| What You Relied On | Human Buyer Era | AI Agent Buyer Era |
|---|---|---|
| Brand storytelling | Wins hearts, drives choice | Largely ignored by agents |
| Gated content | Captures leads | Agents skip it, expect instant access |
| Your website | The destination | Bypassed via data and APIs |
| MQLs and page views | Core metrics | Lose meaning |
| What wins | Best pitch and relationship | Best data, price, and availability |
That is the whole point of restructuring. The rules of the game changed, so the playbook has to change with them.
The New Funnel: How Sales and Marketing Merge
One of the biggest structural changes is that the old handoff between marketing and sales collapses. Let me explain what replaces it.
For decades, B2B ran on a baton-pass model. Marketing generated leads, passed the qualified ones to sales development reps, who further qualified them, and then passed them to account executives. Each handoff lost time and context. In the agent era, that whole relay race condenses.
In what some are calling the “AI marketing funnel,” AI agents handle the tedious qualification and follow-up instantly, turning leads into a real pipeline without the handoffs. Instead of marketing tossing a thousand leads over the fence and hoping sales work them, an AI agent engages every lead the moment it arrives, nurtures it, and only brings in a human when the deal is genuinely ready for a strategic conversation.
This is a big deal for how you structure your teams. The line between sales and marketing blurs. Both become part of one continuous, AI-driven revenue engine. The disciplined, system-level thinking behind this is the same foundation we explored in our guide to hyperautomation in 2026, where coordinated automation replaces disconnected steps.
How Human Roles Change (Not Disappear)?
Let me talk to the worry straight, because it feels like the question everyone’s chewing on: Does this mean sales and marketing jobs go away? The honest answer is no, but it changes a lot.
In practice, AI kind of takes the repetitive, low-value stuff off the board, and then humans slide up the value chain. The grind, cold outreach, data entry, lead qualification, pipeline updates, all of that gets handled by agents. And that leaves your people to do what humans are still genuinely better at: complex deal strategy, relationship building, creative problem-solving, and basically steering the high-stakes deals where judgment matters.
Think of it by role:
- Sales development reps don’t just churn through cold calls anymore. They end up orchestrating AI agents, and they spend more time on the prospects that actually need a real human touch.
- Account executives do less admin and more face time with customers on those complex, solution-based deals where trust, timing, and rapport still do the heavy lifting.
- Marketers go from hand-running campaigns, to strategy and creative direction, and managing the AI systems that can run campaigns at scale without you babysitting every step.
As McKinsey said, generative AI can handle nearly everything across the sales journey, from prospecting to negotiation, with the human touch reserved for the particularly complex, solution-based deals. The teams that win will be the ones that lean into this shift, not the ones who resist it.
And this ties back to a bigger point we mentioned in why AI projects fail: the technology usually does fine, the real failure comes from not adapting the team around it.
The Restructuring Playbook: 6 Steps to Get Ready
Alright, enough about what is changing. Let me give you the practical roadmap to actually restructure sales and marketing for AI. Here is the sequence that works.
- Step 1: Make Your Business Discoverable to Agents – Before an agent can choose you, it has to find you. That means structuring your product data for machine readability, implementing schema markup, writing clear product and category summaries, and making sure your information is accessible, not locked behind gates. Think of it as a new kind of SEO, optimizing not for human searchers but for AI agents doing the research.
- Step 2: Build APIs So Agents Can Transact – Discoverability is step one, but agents also need to be able to actually do business with you. That means building APIs: read-only APIs so agents can check inventory and pricing, transactional APIs so they can build carts and place orders, and post-purchase APIs for order status and tracking. Without this layer, agents can recommend you, but cannot close the loop. This is exactly why a solid API-first architecture has become non-negotiable for agent-era business.
- Step 3: Make Your Data Verifiable – Agents trust verifiable data, not marketing claims. Build trust signals that an agent can confirm independently: real reviews, certifications, compliance attestations, uptime records, transparent pricing, and reliable fulfillment history. Self-proclaimed “best in class” means nothing to an algorithm. Provable track records mean everything.
- Step 4: Deploy Your Own AI Sales Agents – This shift cuts both ways. While buyers use agents to purchase, you should deploy agents to sell. AI SDR agents that engage every inbound lead instantly, qualify it through intelligent conversation, and book meetings directly. The businesses using agentic selling are already seeing real gains, with documented results like 50% increases in customer acquisition and 20% rises in upselling. This is the kind of system our work on agentive AI applications is built around.
- Step 5: Redesign Your Team Structure – Merge the artificial wall between sales and marketing into one revenue engine. Retrain SDRs to orchestrate agents. Free your AEs for strategic deals. Move marketers toward strategy and AI oversight. And invest in change management, because a team that feels threatened will quietly resist even the best restructuring.
- Step 6: Build Governance and Human Oversight – Agents acting autonomously, whether buying or selling, need guardrails. Start with “assisted autonomy,” where agents recommend actions that need human approval before executing. Decide clearly what agents can do on their own and where a human signs off. This protects you legally and builds trust as you scale.
Which Businesses Need to Move Fastest?
Not everyone is on the same timeline. The agent shift hits hardest where buying is transactional, repetitive, and data-driven. Here is who should move now:
- Distributors and wholesalers face the most immediate disruption. Kearney estimates they could see EBIT erosion of up to 500 basis points as pricing becomes transparent and platform fees kick in. For them, becoming an “agent-preferred supplier” is urgent.
- SaaS and software companies are already seeing buyers use AI to research and shortlist before a human ever engages. If your product is not easy for an agent to evaluate, you are losing deals you never even knew you were in.
- Component and parts suppliers serving procurement teams are prime targets for agentic buying, where reordering becomes fully automated. Getting your catalog machine-readable is mission-critical.
- Long-tail and mid-market sellers actually have a big opportunity here. Agentic AI lets you profitably serve smaller accounts that never had a dedicated rep, giving them a “rep-like” experience at scale.
What This Means for Your Business?
Let me bring it home. The $15 trillion shift toward AI-agent purchasing is not some faraway thing you can just plan for later, like, “we’ll get to it.” It’s happening right now, and 2028 is way closer than it feels. The companies that rearrange sales and marketing around AI early are the ones agents will meet, trust, and end up choosing. The ones that wait around will kind of quietly slip off the shortlist, even if the product is actually excellent.
The good news is the path is pretty clear and doable. Make sure you become findable to agents. Build the APIs so they can do transactions smoothly. Make your information verifiable, not vague. Put your own selling agents in the field.
Rethink your teams as one revenue machine, not scattered experiments. And keep governance tight, responsibly. If you do all that, you won’t only survive the change, you’ll be set up to win while most of your competitors are still not even gearing up for what’s coming.
Conclusion: The Buyer Is Becoming a Machine. Get Ready.
Here is the bottom line. By 2028, the majority of your B2B buyers will be AI agents, making decisions based on data, not on relationships or branding. That is a fundamental change to how selling works, and it demands a real restructuring of how you do sales and marketing, not a few tweaks around the edges.
The companies that win will be the ones that started early, made themselves agent-ready, deployed their own AI agents, and rebuilt their teams around a unified, intelligent revenue engine. The $15 trillion is going to flow somewhere. The only question is whether your business is structured to capture its share, or whether you will be invisible when the agents come looking.
You have a head start right now, in 2026. Most of your competitors are still treating this like a future problem. Use that head start. Restructure sales and marketing for AI today, and be the business the agents choose tomorrow.
