When to pick each

// Pick ThriveAI

You want a shipped system, not a slide deck

  • You run a $5M to $250M Canadian operation and the Big Four minimum scope is more than the workflow is worth
  • You want a working system in 100 days, not a strategy deck in 9 months
  • You are a PE portfolio company under operational pressure, not regulatory pressure
  • You want bilingual EN/FR delivery from someone fluent in Quebec French operator culture
  • Your stack is SMB or mid-market (SAP Business One, QuickBooks, M365), not Workday + SAP S/4HANA
  • You want Canadian funding (NGen, Mitacs, IRAP) packaged in, not invoiced as a side scope
  • You do not need Big Four brand cover on the work product
// Pick Big Four

Brand, governance, regulatory cover

  • You are running a $1B+ enterprise where the AI program has 8-figure budget and a steering committee
  • You are in a regulated sector (banking, insurance, healthcare, energy) and the AI posture needs OSFI/OSC/audit signature
  • Your board, investors, or buyers require recognizable consultant brand on the work product
  • You need bundled advisory (SOC 2, tax structuring, M&A diligence) alongside the AI scope
  • You have 12 to 18 months to spend on strategy before you ship
  • You have an internal change-management organization that can absorb 80-page governance frameworks

The hybrid: Big Four governs, ThriveAI ships

For regulated Canadian operators with PE backing, the most common pattern is dual-track:

Common questions

What does a Big Four AI engagement actually cost in Canada?

Typical scopes are CAD 800,000 to 3,000,000+ over 12 to 18 months. Minimum engagement is usually CAD 250,000 to 500,000. Partner rates CAD 450 to 950 per hour blended.

What does Big Four AI consulting ship?

Strategy decks, maturity assessments, target operating models, AI governance frameworks, and one or two proofs of concept. Production builds are usually a separate phase 2 SOW. Daily build work is often done from offshore delivery centers, not by the partners signing the engagement letter.

When is Big Four genuinely the right call?

Regulated sectors needing audit signature; $1B+ enterprises with 8-figure AI programs; complex multi-jurisdiction governance scope; bundled advisory needs (tax, SOC 2, M&A diligence) alongside the AI work.

Can ThriveAI run alongside a Big Four engagement?

Yes. The hybrid is the most common pattern in mid-market Canadian PE: Big Four governs, ThriveAI ships. Both engagement letters live alongside each other.

What is the smallest Big Four engagement I can get?

Typically CAD 250,000 to 500,000 for any AI scope. Below those thresholds you get a junior team with rotational staffing and no partner attention. Most Canadian operators in the $5M to $50M revenue range fall below this floor entirely.

// Scope it live

One call. Honest verdict.

If your scope genuinely needs Big Four signature, we will say so. If it can be shipped in 100 days as a flat fee, we will scope it. You leave the call with the two highest-ROI workflows mapped for your operation either way.
