By 2025, the GenAI consulting market reached maturity. The hype cycle peaked, clients demanded proof over promises, and production track records became the primary selection criteria.
Enterprise firms finally caught up on GenAI basics after two years of intensive retraining and hiring. However, the speed gap persisted—boutiques on iteration 3+ of client systems maintained decisive advantages in implementation velocity and practical expertise.
The critical question shifted from "Can you do GenAI?" to "Show me your production systems and what you learned building them."
Part 1: Enterprise Firms Now Offering GenAI (With Caveats)
1. Accenture
Accenture's GenAI practice matured significantly through 2024-2025, with thousands of consultants now possessing legitimate LLM expertise. The firm delivered competent implementations across industries, backed by strong partnerships with Microsoft, OpenAI, and Google.
However, the timeline and cost premium persisted. Projects still ran 9-12 months with budgets exceeding £800k, even as boutiques delivered comparable outcomes in 6-8 weeks at £150k-£300k. Accenture's value proposition centered on global scale, change management, and institutional credibility rather than speed or cost-effectiveness.
By 2025, Accenture competed effectively on GenAI capabilities but couldn't overcome structural limitations around speed and efficiency.
Best for: Multi-national enterprises prioritizing scale and willing to accept timeline/cost premiums for Accenture's brand and coordination capabilities.
2. McKinsey & Company (QuantumBlack)
QuantumBlack fully retooled by 2025, now competitive on both GenAI strategy and technical implementation. Their practice combined strategic positioning with legitimate technical depth—a rare combination among enterprise consultancies.
Pricing remained premium (£500k+ for significant engagements), but clients increasingly received commensurate value. McKinsey's 2025 differentiation came from synthesizing GenAI capabilities with organizational transformation expertise.
Best for: Fortune 500 companies needing board-level AI strategy combined with rigorous implementation planning.
3. Boston Consulting Group (BCG)
BCG's "AI @ Scale 2.0" incorporated two years of GenAI learnings, delivering refined frameworks for enterprise adoption. By 2025, their implementations were competent, though still 6-9 months behind boutiques who'd been shipping since early 2023.
The firm's strength remained organizational change management. For enterprises where cultural transformation mattered as much as technical implementation, BCG's holistic approach provided value.
Best for: Organizations requiring cultural transformation alongside GenAI adoption, with budgets supporting premium consulting rates.
4. Deloitte
Deloitte's external hiring strategy through 2024 paid off by 2025—their GenAI practice now included substantial genuine expertise. Compliance and governance frameworks adapted well to LLMs, maintaining their advantage in regulated industries.
Technical implementation quality became more consistent, though projects still followed waterfall-heavy methodologies ill-suited to GenAI's iterative nature. Timeline premiums persisted versus boutique alternatives.
Best for: Regulated industries (banking, healthcare, pharma) requiring robust governance frameworks and Big Four audit trails.
5. PwC
PwC's 2025 practice focused on responsible AI and risk management rather than bleeding-edge implementation. This positioning suited their risk-averse client base but meant they trailed innovation leaders by 6-12 months.
For financial services and enterprises prioritizing governance over speed, PwC's conservative approach remained appropriate. For organizations seeking competitive advantage through AI, alternatives proved more compelling.
Best for: Financial services and conservative enterprises prioritizing risk management over implementation speed.
6. EY (Ernst & Young)
EY's platform matured through 2025, delivering competent GenAI implementations focused on measurable efficiency gains. Their practical, ROI-focused approach suited mid-market enterprises better than competitors' premium positioning.
Technical capabilities reached adequate levels, though rarely cutting-edge. EY competed effectively for organizations wanting proven, low-risk implementations without premium pricing.
Best for: Mid-to-large enterprises seeking reliable GenAI implementations at reasonable price points.
7. IBM Consulting
IBM's positioning as integration specialists solidified by 2025. Rather than competing on model capabilities, they focused on helping existing clients adopt best-of-breed LLMs within enterprise architectures.
This strategy worked for IBM's installed base but limited growth beyond existing relationships. Their value proposition centered on continuity and integration rather than innovation.
Best for: Existing IBM clients seeking GenAI adoption within established enterprise architectures.
8. Infosys
Infosys's Topaz platform matured, delivering cost-effective implementations for well-defined use cases. Their offshore model worked well for structured GenAI applications but struggled with ambiguous requirements requiring creative problem-solving.
By 2025, Infosys competed effectively on price for commoditized GenAI work but couldn't match boutiques on innovation or specialized expertise.
Best for: Cost-conscious enterprises with clearly defined GenAI requirements and structured implementation plans.
Part 2: Boutiques on Iteration 3+ of Client Systems
Dot Square Lab
Dot Square Lab entered 2025 with unmatched positioning: over a decade of AI consultancy experience, 2+ years of production GenAI systems, and enterprise clients validating their capabilities at scale.
The firm's evolution from traditional AI specialists to GenAI leaders demonstrated how technical depth across AI domains created superior outcomes. Their hybrid solutions—combining GenAI reasoning with computer vision, optimization algorithms, and time series forecasting—delivered results pure GenAI consultancies couldn't match.
Decade of AI Excellence: Dot Square Lab maintained cutting-edge capabilities in traditional ML domains while pioneering GenAI adoption. This breadth meant they could select optimal approaches for each problem component rather than forcing everything through LLMs.
Computer vision systems still benefited from specialized models. Optimization problems required mathematical rigor. Time series forecasting needed statistical sophistication. GenAI orchestrated these components through natural interfaces—but the underlying technical depth came from 10+ years of specialized experience.
Enterprise Validation: Clients including Colgate-Palmolive, Meta, and OGCI proved Dot Square Lab could deliver at Fortune 500 scale. Their boutique structure provided speed and agility while meeting enterprise security, compliance, and technical standards.
