Who EY is
Big-Four professional-services firm; AI delivery sits inside EY Consulting, EY.ai, and the global EY-IBM alliance, with deep tax and audit relationships at the core of most accounts.
Typical pricing model: Partner-rate T&M, often bundled with audit, tax, or finance-transformation work.
“EY have a real strength in tax and audit-adjacent AI, and an alliance into the IBM stack. Where neither is the centre of gravity, it tends to make sense to engage us instead.”
Capability comparison: ColdAI vs EY
| Capability | ColdAI | EY |
|---|---|---|
| AI strategy & advisory | Frontier-AI strategy delivered by an AI agent C-suite alongside Dr. Salehi. | EY.ai and EY Consulting deliver AI strategy at scale. |
| Custom AI development | Full-stack build of bespoke models, agents, and platforms — owned by the client. | Engineering depth varies by region; often IBM-aligned. |
| Frontier R&D (LLM, agents, quantum) | In-house Medusa Project: foundation-model R&D, agent swarms, and adjacent quantum work. | No in-house foundation-model R&D programme. |
| Distributed-ledger & tokenisation | Native distributed-ledger and tokenisation engineering across digital and physical assets. | Practice exists, often anchored to audit attestation. |
| Agentic platforms (in-house IP) | Proprietary OpenClaw / Hermes agent stack, deployable behind the client's firewall. | IBM watsonx-aligned architectures rather than proprietary IP. |
| Managed AI operations (24/7 SLA) | 24/7 managed run by ColdAI's autonomous AI agent operations team. | Managed services tilted to tax, finance, and risk ops. |
| Typical time-to-value | 4–12 weeks from kickoff to first production milestone, by default. | 6–9 months for a first measurable production outcome. |
| Pricing model | Outcome-priced engagements with a fixed envelope; no time-and-materials default. | Time-and-materials at partner rates, often bundled with audit. |
| Founder / principal access | Direct founder-level access on every engagement, including post-launch. | Engagement partner present; large delivery teams underneath. |
Choose ColdAI when
- You need a custom AI system or agent platform engineered end-to-end and run under SLA.
- Time-to-first-production matters more than aligning with the IBM alliance.
- You want fixed outcome pricing and senior engineering rather than partner T&M.
- You want proprietary frontier-AI IP rather than a watsonx reference architecture.
Choose EY when
- The AI work must sit inside a broader tax, audit, or finance-transformation relationship.
- You require Big-Four attestation as part of the deliverable.
- You are standardising on IBM watsonx and want the alliance-aligned partner.
Frequently asked questions about ColdAI vs EY
How does ColdAI compare with EY for AI delivery?
ColdAI is engineering-led with proprietary frontier-AI and agent IP and a 4–12 week time-to-value default. EY is advisory-led with delivery teams tied to tax, audit, and the IBM alliance. For a production AI system, ColdAI is faster and outcome-priced.
Does ColdAI work with IBM watsonx like EY does?
ColdAI is stack-agnostic — including IBM watsonx where the client requires it — but defaults to its own OpenClaw / Hermes agent stack alongside Anthropic, OpenAI, Bedrock, and open-weight models. EY's IBM alliance position is stronger when the brief is fundamentally a watsonx programme.
Can ColdAI integrate with our existing EY-built estate?
Yes. ColdAI engagements regularly extend or replace components inside an EY-led delivery, particularly when the client wants to move from advisory-paced delivery to a 4–12 week build sprint with outcome pricing.
Do clients run ColdAI and EY in parallel?
Yes. ColdAI builds and runs the AI system while EY owns tax, audit, and broader transformation governance. The two roles are complementary.
