AI consultant
Bringing AI into your business, step by step
I'm Nathan, an independent AI consultant. I help small and mid-sized companies go from idea to a system running in production: an audit first, the use cases that actually pay off next, and an honest no when AI would not earn its keep.
Where to start: an audit before a tool, not the other way round
Most AI projects start backwards: a company buys a tool, then goes looking for something it could do. I work the other way. We start from your real processes, from where your team loses time or money, and work back to the solution. Sometimes that solution is AI, sometimes a simple workflow, sometimes nothing at all: I'll tell you straight.
It begins with a short audit, a few days. I go through your tasks, find the use cases with a real return on investment, and set aside the ones that aren't worth it. You walk away with a costed, prioritized roadmap, not a promise. The report is yours, whether you then build with me, in-house, or with someone else. This is the heart of my audit and optimization work.
- Your processes and the tasks that cost the most time
- Use cases ranked by return on investment
- The real state of your data, before a single line of code
- The traps anticipated: cost, compliance, vendor lock-in
The use cases that actually pay off in SMEs and mid-caps
You don't need flashy AI. The projects that pay are often the least impressive ones: they remove a repetitive task, save hours of searching, or keep support running overnight. Here are the cases I see pay off fastest, with an order of magnitude observed in anonymized settings in brackets.
Each of these maps to a building block I handle: LLM and RAG, agents and orchestration, automation and workflows, audit and optimization. We start with one case, the one that pays off fastest, and expand once the value is proven.
- An internal copilot over your documents that answers in plain language with its sources: a sourced answer in 2 seconds, 70% less time spent searching (consulting, legal).
- Reading and extracting your invoices, contracts and forms, structured automatically: 10x more documents processed per day, zero re-keying (insurance, finance).
- A support agent that answers around the clock and hands off on sensitive cases: 24/7 coverage, 50% fewer tickets escalated to a human (e-commerce).
- Back-office automation: sorting, data entry, follow-ups, reporting, with alerts when something jams.
- Optimizing what already runs: 30 to 70% saved on the audited LLM bill, at equal quality.
Is your data ready? The real failure point
The number one reason AI projects fail isn't the model. It's the state of the data. Scattered across ten tools, incomplete, duplicated or out of date, it will sink the best project. A brilliant model wired to messy data gives you messy answers.
That's why I look at your data before talking technology. Where it lives, as it is. I tell you what's usable right away, what needs cleaning or gathering first, and the shortest path there, without a pointless overhaul. You don't build on sand, and your data stays with you at every step.
Sovereignty and GDPR: a design choice, not a last-minute constraint
Compliance isn't bolted on at the end of a project, it's designed in from day one. EU hosting, private models deployed inside your own infrastructure, data processing agreements: depending on your constraints, we pick an architecture where your data never leaves your perimeter, not to answer, not to act, not to train anything.
Watch out for a common trap: many models, European ones included, run on US clouds and fall back under the US Cloud Act. Real sovereignty comes down to where the model and the connector acting on your tools actually run. Thanks to the MCP standard, we wire your systems once, and that connector can stay on your side, ready to feed a private model when confidentiality demands it. This is the subject of my cloud and on-prem and reliability and security work.
From audit to run: my method in 5 steps
A well-equipped solo consultant moves fast, but not at the expense of rigor. Here's how we go from idea to a system your teams actually run, without a months-long tunnel before the first useful result.
You can enter at any step and stop whenever you like. The full detail is on my method page.
- 1. Audit and scoping. A few days to identify the profitable cases, check your data and cost the expected return.
- 2. Prototype on your real data. A focused POC in a few weeks, to de-risk before you invest: a go / no-go decision backed by measurements.
- 3. Build in production. The system delivered, with evals, guardrails and observability: what separates a demo from a tool you can rely on.
- 4. Handover and documentation. You get a documented architecture with no dependency on me: one point of contact, but no lock-in.
- 5. Run and optimization. I keep it running, harden it and bring the bill down, month after month, if you want.
Costs and expected ROI: what I won't promise
I don't sell miracles, and I won't put a magic number on a brochure. Cost depends on scope, and you'll get an order of magnitude on the first call, for free. What I can commit to: I architect so the token bill stays under control, and on existing systems I often target 30 to 70% savings at equal quality.
What I won't promise: that AI is always the right answer. If the audit concludes that a well-built spreadsheet or a simple workflow is enough, I'll say so, and you'll save yourself a failed project. An honest no after a few days of audit beats disappointment after months of building. That's part of working with an independent: I have no license to sell you at all costs.
Where do I start if I know nothing about AI?
With an audit, not a tool. In a few days I look at your processes and your data, find the cases that pay off, and rule out the ones that aren't worth it. You leave with a clear, costed roadmap, and no technical skills are needed on your side.
How long before I see concrete results?
A first audit read comes back in 48 hours, a prototype on your real data in a few weeks. A full production system runs from a few weeks to a few months depending on scope and the state of your data. We always aim for a useful first result quickly, not a six-month tunnel.
Do I need an in-house technical team?
No. I can handle everything from audit to run and deliver a documented system your teams use without being engineers. If you do have a technical team, I work with it and hand over cleanly. Either way, there's no dependency on me: the architecture is documented, with no lock-in.
What if my data isn't ready?
That's the most common case, and there's nothing shameful about it. The audit says it plainly: what's usable right away, what needs cleaning or gathering first, and the shortest path there. We don't build on sand, and we often move in steps rather than one big overhaul.
What are the risks of an AI project, and how do you limit them?
The real risks: AI that makes things up, that oversteps its scope, or that can be hijacked with a booby-trapped sentence. I contain them with sourced answers, guardrails, access control and red-teaming before go-live. Zero risk doesn't exist, but a known, tested and bounded risk does.
Does the call or the audit commit me to anything?
No. The first call is free with no obligation, and you get a reply within 24 hours. The audit report is yours: you're free to build with me, in-house, or elsewhere. The audit stands on its own.
