Gartner predicts that by 2028, 70% of enterprises will walk away from AI agents built by vendor engineers
AI vendors are sending their own engineers to build agents with customers. Gartner expects most enterprises to drop what’s built that way, and I think that’s an opening for consultancies that hand over the keys.

The short version
- Gartner predicts 70% of enterprises will abandon agentic AI built by vendor forward-deployed engineering (FDE) by 2028, trapped by soaring costs and unable to evolve it on their own.
- It also warns of “FDE washing”. That’s consulting services marketed as FDE, sometimes at premium rates.
- I think clients will want to know who’ll own the agent when the consultancy leaves. If a proposal already answers that, it’s worth saying up front.
What Gartner predicts
Gartner released the prediction on 29 September. By 2028, it expects 70% of enterprises to abandon agentic AI built by vendor forward-deployed engineering, or FDE, “trapped by soaring costs and unable to evolve it on their own”. That’s most of them.
FDE is a model where the vendor’s own engineers work directly with customers “to build and deploy solutions”. Gartner says it’s a pattern that’s familiar from enterprise software, and the new part is “the intensity of the hype”.
How it goes wrong
Gartner says FDE engagements often fail structurally before they fail technically. Customers may see faster early progress, it says, but they won’t necessarily build their own capability, and they can end up paying premium rates.
Once the scope’s clear, Gartner says, a traditional services or partner model could deliver that work more cost-effectively, with more predictable results.
FDE washing
Gartner’s Mukul Saha says many providers now use “forward deployed” as a label for implementation, professional services, solution engineering or AI consulting, “some thoughtfully, others because it sounds more strategic”. Some charge premium fees, he says, when they don’t have the delivery depth to justify them.
Gartner also predicts that through 2028, less than 20% of FDE engagements will turn recurring customer needs into capabilities in the vendor’s core product. It says that’s exposing a growing risk of FDE washing, where consulting services are marketed as FDE.
Gartner’s checklist
Gartner’s list has six items. Saha says the best-scoped FDE engagements have clear guidelines on governance, business value delivery, IP ownership, project co-ownership, knowledge transfer, and an exit strategy from day one.
Gartner’s advice to enterprises runs in three phases. Before signing, write deliverables, knowledge transfer, IP rights and exit into the contract. During the work, embed the vendor’s engineers with the customer’s own people. At the end, carry out the exit plan, rather than extending the engagement because the internal team isn’t ready.

What it means for consultancies
I’d expect clients to start asking a sharper question. Will we own this when you leave?
Let’s say an enterprise wants a service desk AI agent, and it’s choosing between a vendor’s FDE team and a consultancy whose proposal spells out who’ll own the IP, how knowledge will transfer and when it’ll hand over. It’s already covering half of Gartner’s list.

Will we own this
Gartner’s checklist covers IP ownership, knowledge transfer and an exit strategy from day one. If that’s already how you work, it belongs at the top of your website.
Sources and notes
- The 70% and the under-20% are Gartner predictions, not survey results.
- The checklist and the three phases are Gartner’s advice to enterprise software engineering leaders.
- “What it means for consultancies”, “Shane’s take”, the service desk example and the self-check question are my opinion, not Gartner’s.
