Enterprises routinely invest millions into monolithic marketing stacks built by the big clouds—platforms that promise “everything in one place.” In reality, many of those investments yield redundant modules, slow integrations, and underutilized features.
At XDS, we believe in something different: modular, API‑first stacks that let you build what you actually need, more intelligently, more flexibly, and at lower cost. As we’ve argued in Stop Optimizing Your Marketing, Start Fixing the Experience, technology should enable strategy, not weigh it down.
On paper, enterprise marketing clouds offer a seductive promise: one vendor handles CRM, automation, analytics, personalization, content, and more. But that promise often comes with hidden costs:
That’s why leaders tell us they’re paying for scale but losing speed. In regulated sectors, firms like XDS Health see how lock‑in taxes agility when compliance timelines change underfoot.
Use the table below as a quick map to evaluate trade‑offs. “Monolithic” usually means costly and rigid; “modular” tends to be cheaper and more agile.
| Functional Layer | Big Cloud Approach | Modern Alternative | Relative Advantage |
|---|---|---|---|
| CRM / CDP | Salesforce, Adobe CDP — high license, heavy customization | HubSpot CRM, Zoho, Segment, Odoo (open source) | Lower TCO · easier onboarding |
| Marketing Automation | Marketo, Pardot — monolithic workflows, steep learning curve | ActiveCampaign, Customer.io, Autopilot, Zapier stacks | Faster deployment · pay for usage |
| Content & Experience | Adobe Experience Manager, Sitecore — heavy infrastructure & cost | Headless CMS (Contentful, Sanity, Strapi) + composable front end | Developer freedom · scalable performance |
| Analytics & Attribution | Adobe Analytics, proprietary attribution modules | Mixpanel, Amplitude, Plausible, PostHog | Rapid insight · privacy‑first features |
| Advertising / Personalization | Bundled ad/personalization suites from same vendor | The Trade Desk, Clearbit, Mutiny.ai, Optimizely (modular personalization) | Best‑in‑class features · agility |
“Monolithic = costly + rigid. Modular = cheaper + agile.”
You can’t—and shouldn’t—rip out your entire stack overnight. Start small, echoing the approach in AI for the Enterprise: Start Small, Think Big.
We recently partnered with a Fortune 500 client whose legacy marketing cloud cost $2.5M per year in subscriptions, customization, and maintenance. Over three phases, we decoupled automation, swapped out analytics, and re-platformed the CMS.
As we noted in Your Website Is Not Ready for the AI‑First Customer, agility—not sheer scale—defines the next wave of enterprise growth.
The future of enterprise marketing stacks is not monolithic—it’s composable. And as XDS and its partner studios continue to show, cheaper doesn’t mean weaker; it means smarter.
