A global healthcare company puts it bluntly: "If we had an easy way to get out of our Salesforce contract, we would have" — and is about to pilot Shopify in some markets instead. A telecom brand moving off a legacy ESP explains its destination in one line: "Adobe gave us preferential pricing because of our full stack investment with them." A credit union weighed the same move and stayed put: "We already paid for it for the next three years." Consolidation in these interviews is less a strategy than a contract decision, and it runs at the same steady pace whatever the headlines say.
The stack diet: the point categories buyers most often name consolidating, and the platforms they fold into — usually one already under contract. The survivors, for now, are the categories the platforms haven't replicated.
What's being cut — and what absorbs it
Consolidation isn't one move; it's the same move running at different speeds across six categories. The pattern is consistent: the point solution's job migrates into a platform already under contract, and the renewal simply doesn't happen.
| Being consolidated away | Absorbed into | Status | Named by |
|---|---|---|---|
| Standalone SMS tools (Attentive avg 7.8) | Furthest along | a specialty coffee brand, a lawn-care DTC brand — and a children's apparel brand that moved SMS back out | |
| Legacy enterprise ESPs (Oracle Responsys avg 5.7) | Mid-migration | a telecom brand, a national retailer, a global payments company | |
| Standalone CDPs | Under way | a connected-device consumer brand; a wellness-software platform weighing a platform data cloud | |
| Point analytics & A/B testing tools | Early but broad | a premium eyewear brand, a global apparel and footwear group, an enterprise software company | |
| Legacy commerce clouds & commerce point tools (Salesforce Commerce Cloud avg 6.6, Searchspring 6.3, Nosto 6.7) | Shopify (avg 8.1) & single search systems |
Replatform-driven | a national specialty retailer, a global healthcare company, a DTC apparel brand |
| Data & security tool sprawl (ETL, EDR, vuln. mgmt) | Fewer platform vendors | Spreading beyond MarTech | a European luxury group's IT, a major asset manager, a hospitality company |
Steady, not a stampede
The macro pattern A constant concern, a growing AI link
Read answer by answer, the interviews don't show a surge. About one buyer in ten raises consolidating their stack in their own words, without being asked — roughly the same share in 2023, 2024, 2025, and 2026. What has moved is the company consolidation keeps. In 2025, about one in seventeen of the buyers raising it tied it to an AI initiative in the same answer. Since June 2026 it is about one in eight: still a minority, but double. An insurer folded three tools into one — and paid more — because only that tool offered AI-search monitoring.
Toward the contract they already have
Where the cut tools go
Few absorbers, picked by contract
The absorbers are remarkably few, and mostly they rate above what they replace: Shopify (8.1) over Salesforce Commerce Cloud (6.6), Searchspring (6.3) and Nosto (6.7); Adobe Journey Optimizer (6.2) and Salesforce Marketing Cloud (6.8) over Oracle Responsys (5.7). The exception is messaging: Klaviyo (7.7) keeps absorbing standalone SMS from Attentive (7.8) — buyers trade a fraction of a point for one owned-channel program and one bill. But ratings are rarely the reason buyers give. Pricing and existing contracts are. For what triggers a commerce move, see why brands replatform their ecommerce stack, and for the lessons, what buyers wish they'd known before replatforming.

Spreading The same playbook in IT, data, and security
The same move shows up in IT, data, and security interviews. A European luxury group's IT leadership is cutting vendors across its brands — dropping one data-prep tool and renegotiating its ETL. A major North American bank ran a formal feasibility study on its stack before committing. A premium eyewear brand is moving to Amplitude to collapse several analytics tools into one. And security teams run the identical playbook: a major asset manager is moving endpoint protection onto Microsoft Defender on cost, and a hospitality company is cutting overlapping security tools.
The counter-current: consolidation has a price too
Consolidation reliably cuts invoices. It less reliably cuts total cost, or keeps results. A credit union that weighed consolidating decided "the cost of consolidation is too high to disrupt the business" and kept both platforms. A top-ten American bank calls consolidation "easier said than done": the cross-training costs outweighed the dollars saved. An apparel group that moved email and SMS from Listrak onto Klaviyo calls the result a mixed bag, and a children's apparel brand moved SMS onto Klaviyo and then back to Attentive. Traffic runs the other way too: a DTC hair-care brand consolidated Klaviyo, Attentive, and Wunderkind into Listrak (6.7) — a lower-rated absorber than Klaviyo or Attentive.
What this means for your stack rationalization
If you're holding the spreadsheet of every tool and what it costs, the interviews suggest three checks before you cut. First, sequence by absorption maturity: SMS-into-ESP is the well-trodden path — though some buyers move SMS back out — while legacy-ESP and commerce absorption are mid-flight and analytics consolidation is earlier. Second, price the exit, not just the savings: the strongest force in these interviews is the contract already signed, and buyers who stayed put did the math on migration cost, retraining, and prepaid years before they moved. Third, rate the absorber against the tool you cut: most absorbers out-rate what they replace, and the mixed-result stories cluster where they don't. One more, which is our recommendation rather than a practice buyers describe: if the consolidation funds an AI rollout, write that into the business case.
Common questions
Is everyone consolidating their tech stack right now?
Fewer than it sounds. About one buyer in ten in Alium's interviews raises consolidating the stack unprompted, and that share has held steady since 2023. What is growing is the link to AI: since June 2026, about one in eight buyers who raise consolidation tie it to an AI initiative in the same answer, double the 2025 rate.
Which tools get cut first in a stack consolidation?
Standalone SMS tools are the furthest along — buyers describe folding SMS into the email platform they already run, though some move it back. Legacy enterprise ESPs like Oracle Responsys are moving into Adobe Journey Optimizer and Salesforce Marketing Cloud. Standalone CDPs are losing jobs to the data warehouse, and legacy commerce clouds and commerce point tools to Shopify. Analytics and A/B-testing consolidation is earlier, and IT, data, and security teams are running the same playbook.
Which platforms are absorbing the consolidated tools?
In Alium's interview corpus the absorbers are Klaviyo (7.7/10 average buyer rating) and Braze (7.5) for messaging, Shopify (8.1) for commerce, Adobe Journey Optimizer and Salesforce Marketing Cloud for legacy ESPs, and the data warehouse for standalone CDPs. Most rate above the tools they replace — Oracle Responsys averages 5.7 — but buyers more often cite pricing and existing contracts than ratings as the reason they consolidate.
Does stack consolidation actually deliver?
Mostly on cost, less reliably on results. An apparel group that moved email and SMS from Listrak onto Klaviyo calls the result a mixed bag; a children's apparel brand moved SMS onto Klaviyo and then back to Attentive. A top-ten American bank found cross-training costs outweighed the dollars saved, and a credit union kept both platforms rather than pay the cost of consolidating.
