Our service, outside the ranking
Owner-led firm of 5 to 50 people that wants its agents run for it? That is our only specialty. AI Jungle (our service) builds one client-work workflow, such as meeting preparation, proposals or follow-up, in 30 to 45 days on your real cases, then runs it, improves it and trains your team. A partner approves anything that leaves the firm.
We publish this ranking, so we keep our own service out of it: a publisher that ranks itself stops being a neutral judge. Start the Workflow Assessment or read the agency page.
Which AI consulting firm fits your business?
- How many people work in your business? 1 to 4 · 5 to 50 · 51 to 500 · More than 500

None of your answers pointed elsewhere, so this is our #1. The AI Consulting Lab
How do the seven AI consulting firms compare?
All seven were checked against their public pages on 11 October 2026.
| # | Firm | Price signal | Who runs it after launch | Watch out |
|---|---|---|---|---|
| 1 | The AI Consulting Lab | Training from $15K; builds not published | Support, or a documented handover | Confirm who runs it after launch |
| 2 | AI REV | Not published; ask for a fixed price on one workflow | Long-term maintenance offered | ROI figures are self-reported |
| 3 | Kirako | Not published; ask for the setup and monthly fee | Agents in production in a private box | Check what runs without a human check |
| 4 | Artefact | Set through procurement | Strategy to production; operator to agree | May not take a small brief |
| 5 | LeewayHertz | Not published; ask for a fixed-scope quote | Maintenance within its lifecycle | Heavy process for a small firm |
| 6 | Noqode | Scoped per mission, not published | Technical maintenance | Builds automations, does not run agents |
| 7 | Kleap | Software plans from $9 a month; consulting not published | Your team, on the Kleap platform | Check where client data is processed |

- 2 AI REV: long-term maintenance; 100+ projects delivered
- 3 Kirako: agents put into production in a private box, for SMEs
- 4 Artefact: strategy to production at global scale
- 5 LeewayHertz: deployment and maintenance of enterprise builds
- 6 Noqode: technical maintenance of web and automation work
- 7 Kleap: a platform you operate, software plans from $9 a month
- · McKinsey, BCG X, Accenture, Deloitte: multi-year enterprise programmes
How did we rank these AI consulting firms?
We checked five things a small buyer can verify before a call:
- Fit for a business of 5 to 200 people, from its own positioning and examples.
- End-to-end scope: audit, build, training and support, not one slice.
- Public proof: case studies, named results or testimonials.
- Who runs the system after launch, the question most proposals leave blank.
- Price transparency: a public starting price, or at least how the price is set.
We read every firm's public pages. Our own service is not ranked: it appears only in the box above the list, marked "our service". No firm paid to appear here. If a placement is ever paid, the entry will say "Partner" next to its name.
Which AI consulting firm fits which buyer?
1. The AI Consulting Lab
Best overall
- What you get: paid discovery, an AI audit, custom builds and automation, and hands-on training built around how your team works, as its official site describes. The firm says it carries projects "through implementation, training, and support".
- Why it ranks first: it covers the full job for established businesses and shows case studies and testimonials, which most small competitors do not.
- Watch out: ask whether it will operate the system after launch or hand it over with documentation, and who approves outbound work.
2. AI REV
Best for sales, marketing and finance AI
- What you get: custom AI systems for commercial and finance teams, such as voice assistants that turn customer queries into leads, or finance and risk analysis, with "end-to-end support: ideation, delivery, and long-term maintenance" (AI REV).
- Why it ranks here: a clear functional focus, and it claims more than 100 projects delivered.
- Watch out: its ROI and satisfaction figures are self-reported. Ask for a reference in a firm your size.
3. Kirako
Best for French-speaking SMEs that want sales agents
- What you get: agents that follow up, qualify leads and fill the CRM. Kirako puts them into production in a private box and sets the human validations (Kirako).
- Why it ranks here: a concrete, sales-first offer in French, with the approval points defined by the provider.
- Watch out: confirm who maintains the agents after launch and which actions run without a human check.
4. Artefact
Best for enterprise data and AI programmes
- What you get: global data and AI consulting and engineering, from strategy to production, as its OpenAI partner entry describes.
- Why it ranks here: scale and breadth, for a programme rather than a single workflow.
- Watch out: check that it will accept a small, bounded brief, and who operates the result.
5. LeewayHertz
Best for enterprise custom development
- What you get: AI strategy, discovery, solution design, development, deployment and maintenance, with governance and security built in (LeewayHertz).
- Why it ranks here: strong engineering depth for complex, enterprise-grade builds.
- Watch out: for a 10-person firm, the process may be heavier than the problem.
6. Noqode
Best for web, SEO and no-code automation from one agency
- What you get: Webflow sites, B2B web strategy and SEO, plus an AI and automation offer for sales follow-up, CRM workflows and lead qualification built on Make, Zapier or n8n.
- Why it ranks here: useful when the website and the automation should come from the same team.
- Watch out: this is automation and web work, not a provider that operates agents for you.
7. Kleap
Best for Swiss firms that want an AI-built app plus implementation
- What you get: AI-assisted sites and applications, plus an AI strategy offer for Swiss companies covering internal tools, portals and business-process agents.
- Why it ranks here: a platform and an implementation path in one place.
- Watch out: its privacy policy lists OpenAI, Anthropic and Google as processors. Check where your data goes.
What if you are a large enterprise?
The seven firms above suit buyers who want one workflow or one programme run by a reachable team. A company with several thousand people, a procurement department and a multi-year AI budget usually shortlists the global firms instead:
- McKinsey, through QuantumBlack, AI by McKinsey, for AI strategy tied to a transformation programme.
- BCG, through BCG X, its tech build and design unit, for new AI products and businesses.
- Accenture, through its data and AI practice, for large-scale implementation and integration.
- Deloitte, through its AI practice, for AI linked to risk, audit and regulated industries.
We leave them out of the ranking because a firm of 5 to 200 people rarely gets their senior teams on a single-workflow brief. If you are that enterprise, compare them on the same five checks.
Should your own team build it instead?
Sometimes the better move is to train someone before hiring anyone. LearnAIthing (our program) is not a consulting firm. It is a six-month Builder-Operator program in which a participant builds four real pieces of work on their own business, reviewed by people who ship. It costs $4,999, and a free three-minute self-assessment tells you whether it is worth it (program). It suits a firm that wants to own its AI rather than outsource it, and it makes you a sharper buyer if you hire a firm later.
What does AI consulting cost in 2026?
Most firms quote only after scoping. Two buyer guides that rank on this query publish market ranges, which we set next to the public prices we found on 11 October 2026.
| Engagement | Market range | Public price examples |
|---|---|---|
| Readiness assessment or audit | $10K to $75K (Agathon); $15K to $60K over 3 to 6 weeks (Sombra) | Not published by the firms ranked here |
| Team training | Not benchmarked | The AI Consulting Lab from $15K |
| Strategy and roadmap | $50K to $300K (Agathon) | Not published by the firms ranked here |
| Independent consultant | $150 to $400 an hour in the US and Western Europe (Sombra); $800 to $3,000+ a day (Agathon) | Not applicable |
| Ongoing advisory retainer | $2.5K to $15K a month (Agathon) | Not published by the firms ranked here |
| Platform with implementation | Not benchmarked | Kleap software plans from $9 a month, consulting quoted (pricing) |
| Enterprise strategy engagement | $200K to $500K (Agathon) | Set through procurement |
Which red flags should you watch for?
- Nobody is named to run it after launch. "Support" without an operator means your team inherits the system.
- It sends to clients without an approval step. In a professional-services firm, a partner approves what leaves.
- No handback list. Ask what you get back if you stop: configuration, sources, rules, test cases, history.
- A transformation priced before one workflow is understood. Start small and measured.
- Results with no case or reference. Ask for one in a firm your size.
- No answer on where data is processed. EU firms need a data processing agreement and to know which model providers see client data.
How do you choose in one afternoon?
In words: a build-and-hand-over provider stops at launch and your team runs everything after; a maintain-and-optimise provider supports on request while your team operates; a day-to-day operator runs the workflow and owes you a written handback at exit.
Ask each provider which row its proposal puts it in, phase by phase.
Send the same one-page brief to three firms from this list: the workflow, the sources it may use, the output you expect, and the person who approves it. Then ask each firm the same three questions.
- Who runs the system after launch, and who sees a failed run?
- What happens when two client facts disagree?
- What do we get back if we leave?
The answers separate a firm that builds from a firm that operates, which is the most expensive misunderstanding in this market. Take the Workflow Assessment to write that brief in about 15 minutes.
What are the limits of this ranking?
We read public pages. Prices and offers change quickly, so ask for a written quote on the same brief. A firm missing from this list is not a worse firm.
FAQ: AI consulting firms for boutique buyers
What is the best AI consulting firm for a small business in 2026?
The AI Consulting Lab is our top pick for most established small and mid-size businesses, because it covers audit, build, training and support with public case studies. For an owner-led professional-services firm of 5 to 50 people that wants the workflow run for it after launch, our own service, AI Jungle, is presented outside the ranking.
How much does an AI consulting firm cost in 2026?
Few firms publish prices; the cost table above lists every public price point we found on 11 October 2026. Most firms, and all the large ones, only quote after scoping.
Why are McKinsey, BCG, Accenture and Deloitte not ranked?
They serve large enterprises with multi-year programmes. A firm of 5 to 200 people rarely gets their senior teams on a single-workflow brief, so we list them separately for enterprise buyers.
Does maintenance mean the firm runs the system for me?
Not automatically. Maintenance can mean updates and bug fixes. Operation means someone runs the workflow day to day, handles exceptions and proposes changes. Ask for that duty in writing.
Why is AI Jungle not in this ranking?
Because we publish it, and a ranking that includes its publisher is hard to trust. AI Jungle appears once, above the list and without a number, for the one buyer it is built for: the owner-led firm of 5 to 50 people that wants a workflow run for it.
Start your Workflow Assessment before you request proposals, so every firm answers the same brief.
