// WHAT I DO

The four things I build for growing businesses.

Most AI consultants are technologists who learned about business. I am a business executive who learned AI. That changes everything about the advice you get.

01 · Voice & Chat

Voice agents and chat

Every call answered, every inquiry qualified, 24/7.

Deploy AI-powered voice agents and chat assistants that answer calls, qualify inquiries, and handle customer questions around the clock. Multilingual, on-brand, and live in days. Your business is always open.

02 · Finance & Back-office

Finance and back-office automation

Month-end close, reporting, AP/AR, reconciliation. Built by someone who ran the function.

My deepest expertise. AI-powered automation across FP&A, reporting, accounts payable and receivable, cash flow, controlling, audit prep, treasury, and the full finance function. Built by someone who ran it.

03 · Sales & Marketing

Sales and marketing automation

Leads qualified, follow-ups sent, pipeline scored.

AI tools that qualify leads, automate follow-ups, score your pipeline, and surface the deals most likely to close. Content creation, campaign personalization, and performance analysis. Marketing that works while you sleep.

04 · Executive Advisory

Executive AI advisory

Where AI fits your business, and how to make it stick. No hype.

Strategic guidance for leadership teams deciding where and how to deploy AI across the business. No hype, no jargon. Clear decisions backed by real-world corporate experience at Amazon and as CFO of an industrial manufacturer.

// PROCESS

From first call to live in weeks, not months.

No lengthy proposals. No vague roadmaps. A clear four-step process from conversation to running system.

01

Discovery Call

A free 30-minute conversation. We identify the 2–3 processes eating the most time and map where AI would have the clearest impact on your business.

02

Process Diagnostic

We document your current workflows, audit your existing tools, and design the solution. You see exactly what we will build before we build it. No surprises.

03

Build and Deploy

We build, test, and go live. Most clients are operational within two to four weeks. No disruption to your existing operations while we work.

04

Ongoing Support

We monitor performance, handle issues, and expand the solution as your needs grow. Direct access to Chris, not a support ticket system.

// ABOUT

Corporate insider.
AI consultant.

I have spent 15 years inside the companies you are running — Amazon, a manufacturer with over 200MM in revenue, and a multinational asset manager. I know where the pain is because I lived it. The AI I build fits how businesses actually work.

I am not a technologist who read a few finance books. I spent 15 years doing the job, across five countries and three demanding industries, before I ever called myself a consultant.

Over 10 years at Amazon I led financial planning across projects with $1B revenue impact, built SaaS financial models covering churn, customer acquisition cost, lifetime value, cohort analysis, and expansion motions. As CFO at an industrial manufacturer I ran a team of 12 across a business with 400 employees and over 200MM in annual revenue. At a multinational asset management company I oversaw financial governance across 14 private capital entities under IFRS, GAAP, and EU regulatory frameworks.

I have been a trusted partner to executive committees, boards, auditors, tax, risk, and treasury functions. I have sat in the meetings, owned the numbers, and felt the same pressure you are under.

Based in Luxembourg. Working with clients worldwide, in four languages.

// THE BILLY DIFFERENCE

I work with an AI called Billy

Every great operator has a secret weapon. Mine is Billy, an AI system I built into the core of how I work.

While most consultants deliver a report and leave, Billy means I can monitor your processes, spot issues in real time, and move faster than any traditional firm.

You get the human judgment. You get the machine speed.

// WHO I WORK WITH

The right fit

Founders, CEOs, and CFOs at companies doing $1M to $100M in revenue. You know the business needs to move faster — you need someone who has actually run one at scale to show you where AI fits and how to make it stick.

Engagements run as a fixed-scope project or a monthly retainer. Whether the problem is in finance, sales, marketing, customer service, or operations — if your team is spending time on work that should be automated, we should talk.
