Theory vs
management consulting
A management consultancy sells a team, a framework and a large deliverable, priced by time and rarely disclosed in advance, in which the evidence base is often difficult to audit. Theory Intelligence sells verified evidence and a signed recommendation at a fixed published price, with a provenance appendix that lets the client trace every claim.
Theory vs Management Consulting
| Management consulting | Theory Intelligence | |
|---|---|---|
| What you buy | A team for a period; slides; a framework | A signed answer with verified evidence behind it |
| Evidence base | Mixed: desk research, some calls, expert networks, increasingly AI-drafted | Verified interviews and checked documents, listed in a provenance appendix |
| AI disclosure | Rare; 70% of clients say they would not trust an AI-prepared report | Written, specific to the engagement, in every deliverable |
| Pricing | Time-based or opaque fixed fee, typically USD 150,000 and up for a diligence | Published: Decision Study USD 25,000 to 75,000 |
| Accountability | Firm brand; partner rarely signs a position | Named researcher signs the recommendation |
| Team | Leverage model: junior staff do the work, partner presents | The researcher who does the work writes and presents it |
| Speed | 6 to 12 weeks typical | Decision Study 4 to 6 weeks; Signal Brief 10 business days |
| Best for | Large transformation programmes needing many hands | Decisions that need evidence and a position, not a programme |
What consultancies are for
A large consulting firm is built to deploy many people on a problem for a long time. For a transformation programme, a post-merger integration or a multi-country rollout, that is what is needed. The leverage model, in which junior staff do the work and a partner sells and presents it, is how the firm makes money and how it scales.
Where it went wrong
In 2025 and 2026 the leverage model met generative AI. Junior staff drafted with it. Nobody checked. Deloitte Australia refunded part of a A$440,000 fee after a report cited a court judgment that did not exist. PwC published reports whose footnotes led nowhere. By August 2026, Source Global Research found that 70 percent of 3,887 companies would not trust a report prepared with AI. KPMG pressed a supplier for a fee cut on the grounds that AI had made the work cheaper. Clients had discovered that they were paying time-based fees for work whose evidence they could not audit and whose efficiency gains they did not share.
What Theory does differently
Theory is not a consultancy in that sense. There is no bench to keep busy and no leverage model. The researcher who runs the interviews writes and signs the recommendation. Every participant is verified, every document checked, every claim traceable in the provenance appendix, and AI use is disclosed in writing. The price is published: a Decision Study, which covers what a consulting firm would call commercial due diligence or a market assessment, is USD 25,000 to 75,000 fixed.
When to use which
Use a consultancy when the problem needs many people for months. Use Theory when the problem is a decision that needs evidence and a position: an acquisition, a market entry, a pricing move, a vendor selection. Some clients use Theory to check the evidence in a consultancy's report before they act on it.

Questions people ask
Is Theory a consulting firm?
Theory is a research and advisory firm. We deliver verified evidence and a signed recommendation at a fixed price. We do not deploy teams for transformation programmes.
How much cheaper is Theory than a strategy firm?
A Decision Study is USD 25,000 to 75,000. Comparable commercial due diligence from a strategy firm is commonly USD 150,000 and up. The difference is the absence of a leverage model, not a thinner evidence base.
Can Theory check a consultant's report?
Yes. A Signal Brief can test the key claims in an existing report against verified interviews and checked sources in ten business days.
