The Hidden Cost of Enterprise AI Consultants When You Have 15 People
The Hidden Cost of Enterprise AI Consultants When You Have 15 People
TL;DR: Enterprise AI consultants charge EUR 150-350 per hour with 12-18 month timelines. For a 15-person company, the mismatch is structural. Here is what it act…
Enterprise AI consultancies in Europe typically charge between EUR 150 and EUR 350 per hour. Their standard engagement timelines run 12 to 18 months. For a company with 500 employees, a dedicated IT department, and an annual technology budget in the millions, those numbers make sense — the consulting spend is a small percentage of overall technology investment.
For a North Holland SME with 15 people, those same numbers represent a fundamentally different proposition. A six-month engagement at mid-range rates can easily exceed EUR 100,000 — a figure that, for many SMEs in the 10-50 employee range, is a significant share of their entire annual operating margin. The problem is not that the consulting is bad. It is that the model was never designed for you.
The Pricing Mismatch Is Structural
Enterprise consultancies price for enterprise economics. Their rate cards reflect the overhead of large delivery teams, global offices, proprietary frameworks, and senior partners who manage client portfolios. When those firms engage with a 15-person company, they do not meaningfully adjust the model — they adjust the scope, which means you get a narrower version of an enterprise engagement at a rate that still reflects enterprise cost structures.
The result is a pricing mismatch that compounds at every stage:
Discovery and scoping runs longer than necessary because the consultancy's methodology assumes a complex stakeholder landscape. Your company has five decision-makers and two core systems. The discovery process designed for a 500-person organisation creates overhead that delivers no additional insight at your scale.
Delivery teams are oversized. Enterprise engagements assign multiple consultants — a senior partner, a project manager, a technical lead, analysts. A 15-person company does not need that team structure. But the engagement model requires it, and the billing reflects it.
Timelines are calibrated for enterprise decision cycles. Large organisations take months to approve vendor selections, align stakeholders, and schedule implementation windows. Your company can move in weeks. But the consultancy's project plan is built around the longer cycle, and you pay for that pace.
The Hidden Costs Beyond the Rate Card
The visible cost — the hourly rate times the projected hours — is only part of the picture. For a small team, the hidden costs are often larger:
Internal time consumption. Enterprise consulting engagements are meeting-intensive. For a 15-person company, every two-hour workshop requires pulling key people away from revenue-generating work. When your Head of Operations spends 20 percent of their time servicing a consulting engagement, that is a real cost to the business — and it does not appear on the consulting invoice.
Recommendations that require enterprise infrastructure. Enterprise consultancies tend to recommend solutions from their partner ecosystem — platforms, tools, and integration patterns designed for organisations with dedicated IT teams. A 15-person company implementing those recommendations needs to hire additional technical capacity to operate what was recommended, creating a secondary cost layer the original engagement did not account for.
Governance overhead scaled for the wrong context. Enterprise compliance frameworks are rigorous, which is appropriate for large-scale AI deployments. But applying the same governance architecture to a single AI use case in a 15-person company creates a compliance overhead that is disproportionate to the actual risk.
Renewal and dependency patterns. Many enterprise consulting engagements are structured to create ongoing dependency — Phase 1 leads to Phase 2, which requires Phase 3. For an SME, each phase represents a budget commitment that may not be justified by the incremental value delivered.
What a 15-Person Company Actually Needs
The AI consulting needs of a 10-50 person company are genuinely different from those of an enterprise. Not simpler — different.
A single senior advisor, not a team. You need one person with enough technical depth and business judgment to make AI decisions with you — not a project team of six billing against your engagement. The right model is a fractional CTO or retained AI advisor who knows your context and can make decisions quickly.
Speed-matched engagement. Your organisation can move from decision to pilot in weeks, not months. The consulting model should match that pace. If an advisory engagement requires a 12-week scoping phase before any value is delivered, it is designed for a different kind of client.
Recommendations scaled to your operating reality. The right AI tools for a 15-person company are not stripped-down versions of enterprise platforms. They are often different tools entirely — lighter, faster to deploy, easier to maintain without dedicated technical staff. Your advisor should know the difference.
EU AI Act compliance that is proportionate. The EU AI Act applies to your AI use cases based on risk classification, not company size. But the governance approach should be proportionate — adequate documentation, appropriate transparency, and clear accountability without the overhead of an enterprise compliance programme.
The Real Cost Comparison
For context, here is how the economics typically compare for a North Holland SME considering AI adoption support:
An enterprise consulting engagement at mid-range rates (EUR 200/hour), scoped at 20 hours per week over six months, costs approximately EUR 96,000 — before internal time costs, before implementation costs, and before the recommendations are acted on.
A fractional CTO or ongoing AI advisory retainer for the same period — providing senior-level strategic guidance, vendor evaluation, governance oversight, and implementation steering — typically runs at a fraction of that figure. The advisory model is designed for your scale: fewer hours, higher-leverage decisions, no delivery team overhead.
The comparison is not "cheaper consulting." It is a fundamentally different model designed for the economics of a 10-50 person organisation.
How to Evaluate Your Options
Before committing to any AI consulting engagement, run these numbers for your organisation:
Total engagement cost. Not just the quoted rate — include the projected hours across all phases, all team members billing against your engagement, and any platform or tool costs embedded in the proposal.
Internal time cost. Estimate how many hours per week your key people will spend supporting the engagement. Multiply by their effective hourly cost to the business. Add that to the engagement cost.
Implementation cost. Will the recommendations require additional hires, platform subscriptions, or integration work? Factor those into the total cost of following through on the consulting output.
Time to value. How many months from engagement start to the point where your organisation is actually operating differently? If the answer is 12-18 months, evaluate whether an advisory model could get you there in six.
What happens when the engagement ends? If the answer is "we need another engagement," the model is creating dependency, not capability.
The Right Model for Your Scale
Enterprise consulting exists because enterprises need it. But the consulting market has a gap: serious, senior-level AI advisory designed specifically for companies with 10 to 50 people. Not diluted enterprise consulting. Not generic small-business tech advice. Genuine AI strategy and execution support calibrated for the economics, pace, and operating reality of a North Holland SME.
That gap is exactly where the fractional CTO model fits.

Frequently Asked Questions
How much does enterprise AI consulting cost for a small company?
Enterprise AI consultancies in Europe typically charge EUR 150-350 per hour with engagement timelines of 12-18 months. For a 15-person company, a six-month engagement at mid-range rates can exceed EUR 100,000 before internal time costs and implementation expenses are factored in.
Is enterprise AI consulting a bad choice for an SME?
It is not bad — it is mismatched. Enterprise consulting models are designed for organisations with large IT departments, complex stakeholder landscapes, and technology budgets in the millions. For a 10-50 person company, the same methodology creates disproportionate overhead in discovery, delivery team size, and timeline without delivering proportionally more value.
What is the alternative to enterprise AI consulting for a small Dutch company?
A fractional CTO or retained AI advisor provides senior-level strategic guidance at a fraction of the cost. The model is designed for SME economics: a single senior advisor rather than a delivery team, speed-matched engagement, and recommendations scaled to your operating reality.
Does company size affect EU AI Act compliance requirements?
The EU AI Act classifies risk by use case, not by company size. A 15-person company using AI for customer risk scoring faces the same transparency and documentation requirements as a 5,000-person enterprise. However, the governance approach should be proportionate — you need adequate compliance without enterprise-scale overhead.
