Comparison
economAIcs vs Big Four AI advisory
The brand is reassuring. The structure is generalist.
Large professional-services AI practices carry real scale, brand credibility and cross-industry pattern recognition. This page is about what changes when a firm is small, transport-only, and structurally unable to advise both sides of a competition.
What Big Four AI advisory does well: credit where due
Scale to run large, multi-workstream programmes, brand credibility that reassures a board, and AI capability tested across many industries and geographies. For a global or multi-function engagement, that scale is a real advantage and nothing on this page argues otherwise.
Where the model shows its structure
1. The team turns over. A partner sells the engagement; a rotating bench of analysts and associates delivers it, with sector context re-learned at each rotation.
2. AI is a shared capability, not a specialism. The same AI practice serves every client industry the firm has, so transport depth is layered on top rather than built in from the start.
3. The same firm can sit on more than one side. A professional-services group's other practices may audit, assure or advise other parties active in the same market, a structural possibility a smaller, single-sector firm does not carry.
4. The relationship is designed to continue. Findings arrive alongside further scopes of work, because the commercial model rewards an extending engagement, not a fixed one.
Side by side
| Big Four AI advisory practice | economAIcs, The Practice | |
|---|---|---|
| Team you actually get | A partner for the pitch, a rotating team of analysts and associates for delivery | One senior leader throughout, backed by our own transport-trained AI |
| Sector specificity | AI capability shared across every industry the firm serves | Transport-only: procurement mechanics, franchising and evaluation frameworks are native |
| Cost structure | Day rates across a pyramid of grades, scoped after discovery | Fixed scopes and outcome pricing; the entry Readiness Review is a published fixed fee |
| Speed | Multi-week mobilisation before the engagement properly starts | AI-accelerated discovery: our AI reads your documents and public footprint before the first meeting |
| Proprietary tooling | Generic AI accelerators, licensed or built for cross-industry use | A transport-trained Brain we run daily on our own business and our clients' |
| Independence and conflicts | The same firm may audit, assure or advise other parties in the same market | Where we assure, we do not build. We never advise both sides of one competition. |
| Proof model | Case studies and credentials from other clients and other sectors | We run our own transport-trained AI as a live product: we do not talk about applied AI in transport, we run it |
| Exit | Recommendations and a relationship the firm expects to continue | A costed roadmap with a named delivery route, or your own Brain if you choose to build and run it |
When a Big Four AI practice is the right choice
Multi-function, multi-geography programmes, a need for the assurance relationships an established professional-services firm carries, or board-level brand credibility as part of the requirement itself. Real strengths, honestly stated.
When The Practice is the right choice
Choose economAIcs if:
- You want one senior leader throughout, not a rotating bench
- You want a firm that is structurally independent of every other party in your market
- You want a transport-trained Brain, not a generic accelerator
- You want fixed scopes and a published entry fee, not day rates
- You want the roadmap to end in a named delivery route, not a continuing relationship
FAQ
Are Big Four AI practices not credible on transport?
Large firms field real AI capability and often long-standing transport relationships. The difference is structure, not competence: a global professional-services firm serves every industry from the same AI practice, while we exist for one sector only, and stay independent of the parties we advise on any one procurement.
When is a Big Four AI practice the right choice?
When the engagement needs a globally-recognised brand for board or investor confidence, spans functions well beyond transport, or requires the assurance and audit relationships that come with an established professional-services firm. Real strengths, honestly stated.
What do you mean by independence and conflicts?
Where we assure, we do not build. We never advise both sides of one competition. We never advise both sides of the same competition, and client data is never used to train shared models. Where we assure, we do not build: an authority buying our judgement is never buying a sales channel.
What does The Practice cost?
The AI Readiness Review is a published £2,000 fixed fee, credited against any engagement that follows. Everything else is a fixed scope agreed on a call, with no day rates and no pyramid of grades.
Built by someone who's sat where you sit, a decade leading commercially in transport technology.
