Hyper-personalization Article

<a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/critics/andycohen">Andy Cohen</a><a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/critics/deane"> </a>is the founding architect of Sitecore XM Cloud. He is VP/Chief Architect at <a target="_blank" rel="noopener noreferrer" href="https://www.altudo.co/">Altudo</a>, and a CMS Critic contributor. <hr /> When people talk about personalization, they often mean “the right content to the right person at the right time.” That idea is now past tense.I have watched this shift play out up close, from <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/products/sitecore">Sitecore’s</a> early rules-based personalization, through <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/products/contentstack">Contentstack’s</a> use of edge-based personalization in a composable architecture, to <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/products/optimizely">Optimizely’s</a> launch of Opal, a system of marketing AI agents. Personalization no longer stops at swapping content on a page. It now reaches into the interaction itself, and soon, into the relationships agents form with one another.<h3 id="when-agents-adapt-to-us">When Agents Adapt to Us</h3>That shift, from “what” to “how,” is where the major CMS players are already moving, and you can see it in the different bets they're making:<ul><li>Contentstack has put its weight behind <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/livin-on-the-edge-contentstacks-new-adaptive-dxp-might-just-rock-your-world">EDGE</a>, which they call a hyper-personalization platform. It blends their headless CMS with a real-time CDP, AI, and automation. The goal is simple but ambitious: deliver one-to-one experiences in the moment and at scale. Because it is composable, brands can adapt interactions without locking themselves into rigid patterns. What strikes me about EDGE is that it reframes personalization as something continuous, not a campaign you set and forget.</li><li>Optimizely has taken another route with <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/optimizely-opal-gets-supercharged-for-agentic-ai-powering-infinite-use-cases-for-marketers">Opal</a>. Instead of a single assistant, Opal is built as a collection of agents that act like members of a marketing team. There is a campaign manager agent, a personalization advisor, a market researcher, and more. With the 2.0 release, Optimizely put the emphasis on letting these agents collaborate and run multi-step workflows across content, data, and experimentation. I have seen teams spend weeks coordinating those same steps manually. Opal hints at a world where marketing execution is handled by an ensemble of digital teammates who can plan, act, and adjust together.</li><li>Sitecore has focused on bringing assistance directly into daily work. Through <a target="_blank" rel="noopener noreferrer" href="https://www.sitecore.com/products/sitecore-stream">Stream</a>, they have introduced AI copilots that support authors and marketers in real time as they draft and optimize campaigns. On top of that, Sitecore’s partnership with <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/sitecore-sharpens-ai-focus-with-strategic-partnership-and-new-leadership-appointments">Gradial</a> shows how agentic workflows can extend into campaign execution. It is not just about smarter editors or quicker drafts. It is about agents that can carry intent through to delivery and adapt along the way. For a company that has lived for years in the world of static content publishing, that is a meaningful step forward.</li></ul>None of these approaches feels like a gimmick.They are different answers to the same problem: personalization is no longer about what content you are shown, it is about how the interaction unfolds. Whether that happens through hyper-personalization at the edge, through orchestrated marketing agents, or via copilots and execution partners, the shift is real and already in motion.<h3 id="what-nondeterminism-really-means">What Nondeterminism Really Means</h3>Most software behaves like math: 2 + 2 always equals 4. Generative AI does not. Ask it to draft a thank-you note and you will get three different answers, all plausible, none identical. That variability is what we call nondeterminism.It is the very thing that makes AI feel creative, but also the reason it needs personalization to stay useful. As <a target="_blank" rel="noopener noreferrer" href="https://parivedasolutions.com/perspectives/managing-the-non-deterministic-nature-of-generative-ai/">Pariveda Solutions points out</a>, nondeterminism is what makes AI flexible and creative, but it also introduces governance challenges that remain unresolved. In my own work with <a target="_blank" rel="noopener noreferrer" href="https://cmscritic.com/getting-loud-with-xm-cloud-sitecore-reports-100-growth-of-its-ai-powered-cloud-based-cms">XM Cloud,</a> I have seen how unpredictable outcomes can be a feature if the system adapts well – and a liability if it does not.<h3 id="when-agents-adapt-to-each-other">When Agents Adapt to Each Other</h3>The next frontier is agents adapting not just to us but to each other. Nondeterminism multiplies when two autonomous systems interact. They need ways to converge on workable outcomes.Sometimes that looks like adjusting communication style, where one agent is structured and terse, another free-form and verbose. Sometimes, it means learning to accept differences in task style, such as fast approximation versus cautious step-by-step reasoning. Other times it's about role negotiation: who leads, who validates, who escalates.And sometimes it is memory. Agents do not just adapt in the moment; they remember. That memory can look like a grudge. A search agent that hallucinated last time will get fact-checked the next. A procurement agent that botched a deal may face stricter oversight. Even first impressions stick. If an agent’s very first hand-off is sloppy, the other agent may never fully trust it, no matter how good the later work becomes.Humans behave the same way. In corporate life, one bad kickoff meeting can color a partnership for months. Agents will carry those patterns too.<a target="_blank" rel="noopener noreferrer" href="https://www.deepset.ai/blog/ai-agents-and-deterministic-workflows-a-spectrum"> Deepset calls this the “spectrum of determinism to nondeterminism</a>.” I call it relationship management.<h3 id="everyday-illustrations">Everyday Illustrations</h3>Picture a grocery agent told to buy apples if they are $0.99 a pound. A deterministic system comes back empty because they are $1.09. An adaptive one checks with you, “They are a little higher today. Should I buy anyway?” That is useful, until the store’s own agent learns to nudge yours into paying even more.Or ride-hailing. You set a $20 target. The price surges to $23. Do you want your agent to decline, wait, or decide on its own? What happens when the ride-share’s agent starts upselling yours into priority pickup at $28?Or travel. You say, “Book me a flight under $500.” The system finds none. A flexible agent returns with, “There is one at $525 with better times. Should I grab it?” Helpful, but it shows how quickly rules can bend.In the enterprise, this gets thornier. Procurement policies might cap software licenses at $50 per seat. A deterministic agent halts the deal. A personalized one negotiates to $55 and closes it. That looks like a win until you realize the vendor’s agent deliberately anchored higher, knowing yours would flex upward.Healthcare raises the stakes even more. You ask for an appointment with your doctor next week. A rigid agent says none available. A personalized one offers a nurse practitioner tomorrow or a specialist in two weeks. That looks like a better experience, but it could also push you toward higher-margin services instead of the care you really wanted.<a target="_blank" rel="noopener noreferrer" href="https://www.salesforce.com/blog/deterministic-ai/">Salesforce has written about this exact problem</a> of when to script agents tightly and when to let them roam. I see it every day in delivery projects. Too rigid and you frustrate users. Too loose and you open the door to manipulation.<h3 id="agents-that-carry-“you”-with-them">Agents That Carry “You” With Them</h3>Now push it further. Imagine your agent not only executes tasks but carries your personality footprint into every interaction. If you are cost-sensitive, it pushes harder. If you are time-poor, it pays more for speed. If you are detail-driven, it double-checks everything.What if you could swap personas entirely?<ul><li>"Frugal Andy" does the grocery shopping</li><li>"Executive Andy" books the flights</li><li>"Playful Andy" explores games and hobbies.</li></ul>Your agent would not only personalize to you. It would personalize as you.But there is risk in this. If the other agent knows who you are or which persona you are using, it can adapt back. That can be powerful when aligned with your goals, but it can also be exploited. Imagine a vendor agent that recognizes executive mode and steers you toward premium packages.This is not hypothetical. Optimizely’s Opal agents already act like different team members depending on context. Contentstack’s Brand Kit lets you define voice profiles and store guidelines so that every AI-generated artifact reflects your identity. Sitecore’s Stream copilots are designed to guide content creators in real time, aligning their work with brand and role expectations.These are early signals of a future where agents carry pieces of us, including quirks, preferences, and even biases, into every exchange.<h3 id="why-this-matters">Why This Matters</h3>This is why nondeterminism is not a flaw but the feature. Deterministic systems did not need personalization. There was only one output. Nondeterministic systems can go in many directions, and personalization is what prevents chaos.The best metaphor I know is jazz. Musicians improvising do not know exactly where the others will go. They adapt, they respond, they personalize their playing to the group. The music works not because it is scripted but because the players trust each other enough to bend and flex.<a target="_blank" rel="noopener noreferrer" href="https://www.mckinsey.com/capabilities/quantumblack/our-insights/seizing-the-agentic-ai-advantage">McKinsey has argued</a> that this adaptability is the defining advantage of agentic AI. From what I have seen in publishing systems, SaaS cost optimization, and large-scale CMS migrations, I agree. The resilience comes not from rigid plans but from the ability to adapt in context.<h3 id="what-leaders-should-prepare-for">What Leaders Should Prepare For</h3>Leaders should focus on their readiness in key areas. For example, trust frameworks must extend beyond human-agent interactions into agent-to-agent ecosystems. Standards cannot stay as fixed APIs; they need flexibility built in. Identity management has to protect personality profiles and alter egos from misuse. And agents must be able to remember not just what they did for us, but how they worked with others.<h3 id="the-future-of-personalization">The Future of Personalization</h3>Personalization started with content. It evolved into experiences. Now, it is moving into interactions – first with humans and then with other agents.If we get this right, nondeterminism will not be something to suppress. It will be the source of resilience, adaptability, and creativity. The companies that thrive will not just personalize their websites. They will personalize their agents. Those agents will adapt to us, and to each other, in ways that reflect who we are or even who we choose to be.And like humans, they will remember. First impressions will matter. Grudges may form. And relationships between agents will start to look a lot like relationships between people. <hr /><h3 id="upcoming-events">Upcoming Events</h3> <img style="width:31.61%" src="https://cmscritic.com/ms-content/uploads/2025/08/storyblok-joyconf-2025-logo.jpg" /><h4 id="storyblok-joyconf-2025"><a target="_blank" rel="noopener noreferrer" href="https://joyconf.storyblok.com/">Storyblok JoyConf 2025</a></h4>October 14-15, 2025 – Amsterdam, Netherlands November 4, 2025 – New York, NY November 6, 2025 – Los Angeles, CAJoin us at JoyConf 2025, where the future of content meets the people shaping it.
