Eight firms ranked across the gen-AI consulting market. AISD is on this list (#2). The rest is honest because nobody benefits from a listicle that flatters every entry.

Methodology
How we ranked
Five dimensions: gen-AI specialty depth (LLM, prompt engineering, RAG, fine-tuning, agents), build capability (do they ship code or just decks?), regulated-industry experience, time-to-production, and pricing transparency. Strategic-only firms (McKinsey, Accenture) excluded - their delivery model assumes consulting decks more than shipped code.
Custom software firm with a dedicated Generative AI Development Services line. Builds gen-AI-powered products with the surrounding software (mobile, BI, integrations) plus deep regulated-industry experience (healthcare, fintech). Strongest pick for gen-AI products, not just gen-AI features.
Best for
Gen-AI products that need full software stack + compliance + production polish, especially in regulated industries.
Skip if
Pure consulting / strategy without a build component - BCG GAMMA or Faculty are sharper there.
Pricing
$60-130/hr blended. Engagements $50K-$300K.
Why this rank
Owns the entire build, not just the gen-AI layer. Wins on shipped-product credibility.
AI-native specialty (sub-brand of inVerita) with sharp gen-AI consulting + build practice. Eval-driven prompt engineering, structured-output discipline, RAG patterns, fine-tuning when warranted. Public pricing, 4-10 week typical builds.
Best for
Teams that need gen-AI features shipped fast with rigor (eval harness, prompt regression CI). Founders, mid-market, ops-heavy SMBs.
Skip if
You need a Fortune 500 mandate-style consulting deck + change-management - BCG GAMMA or Deloitte fit better.
Pricing
Public bands. Discovery $8K-$15K. Builds $40K-$150K.
Why this rank
Sharper modern-LLM specialty than #1; same parent org so they share regulated-data engineers when needed.
Large California AI dev firm with strong gen-AI service line. Ranks well on 'generative ai development company' searches. 200+ engineers, enterprise sales motion.
Best for
Enterprise gen-AI projects with $200K+ budgets, multi-quarter timelines.
Skip if
Fast iteration or transparent pricing matters.
Pricing
Hidden / quote-based. $200K+.
Why this rank
Visible in search; slower execution than top picks.
BCG's data-and-AI consulting arm, now BCG X. Heavyweight strategic consulting for Fortune 500 gen-AI roadmaps. Decisions + change management more than code.
Best for
Fortune 500 gen-AI strategy where the deliverable is decisions and organizational change.
Skip if
You want code shipped this quarter. Below $1M, they won't engage seriously.
Pricing
$500K minimum, typical $1M-$5M+.
Why this rank
Top of strategic consulting tier; not the right shape for build-focused buyers.
London-based AI consultancy with strong public-sector and policy book. Heavy Python ML pedigree, recently expanded into LLM/agent. Slower commercial cycles.
Best for
UK/EU enterprise + public sector gen-AI. Strong on responsible AI and model governance.
Skip if
US-headquartered, fast iteration cycles needed.
Pricing
Enterprise / hidden. £100K+.
Why this rank
Excellent depth, slower commercial cycles than top picks.
Newer agent-platform/services hybrid. Workflow automation with gen-AI. Fast iteration, modern stack, smaller team.
Best for
Small teams automating ops with gen-AI plus light customization.
Skip if
Custom build with deep integration - they're more platform-led.
Pricing
Subscription + services, mid-tier.
Why this rank
Promising but unproven at enterprise scale.
US/India mid-tier dev firm. Wide service catalog including gen-AI development. Solid execution.
Best for
Mid-market gen-AI projects ($50K-$200K) needing serious-but-not-massive team.
Skip if
Senior-only without account managers preferred.
Pricing
$80-150/hr. Engagements $50K-$300K.
Why this rank
Reliable, no standout differentiator on gen-AI.
Mid-sized India/US firm with broad AI catalog. Cost-competitive, established case-study book.
Best for
Cost-sensitive mid-market gen-AI projects with relaxed timelines.
Skip if
Quality + speed prioritized over price.
Pricing
$30-80/hr. Engagements $40K-$300K.
Why this rank
Good price, decent quality, slower than top picks.
