CRO & Growth for DTC brands | ex-CXL

I use code and AI to build systems, automations and apps that solve problems for marketing and sales teams.

CRO, User Research and Experimentation Consultant

Quit my full-time job at Speero (previously CXL Agency) in Oct 2020. Spent 3 months reading a lot of books and relaxing. Finally started my own CRO consulting business in Jan 2021.

Is anybody building a Claude Code based marketing agency?

For example a Claude Code SEO agency.

This is what it would look like:

- IDE (Cursor, Antigravity, etc) + Claude Code as the UI of work

- Automated outbound system using Clay + Instantly (or their own copycat solution)

- Custom slash commands for text creation output (email to clients, research, etc)

- Claude Skills for all the service delivery tasks (keyword research, link building outreach, technical SEO, etc)

- MCPs to connect to existing service APIs (aHrefs, Screaming Frog, Moz, Clickup, etc)

- Multiple instances of Claude Code running in parallel for each client

- Custom project management tool to orchestrate tasks to Claude Code (or Agent SDK)

- Own custom apps that Skills / MCPs can use

- Cron-jobs to deliver reports / updates to clients

- Human in the loop review and validation system for AI work.

1 SEO Claude Code native expert could probably manage 20-30 clients with this setup.Basically a service based business with AI & SaaS behind it.

If you are considering it, DM me, we should chat.

I'm a visual person.

Probably I'm not the only one.

So when the Anthropic team has a new release in text format, I very often struggle understanding what it does, how it works and how I can use it.

Especially if I'm not under the influence of a coffee.

These guys are shipping like madmen, so I always want to be up to date on new feature releases.

So now I've created a new Claude Skill that does the following:

I feed the Github Change Log link (where Anthropic publishes new feature release communications) to Claude.

Claude creates an app (using artifact Skills) where for each new Claude Code feature:

1️⃣ It sets the context about the feature

2️⃣ It explains what it does in simple and clear terms

3️⃣ It shows me step by step on how it works and how I can use it

4️⃣ It has a chat with each feature window in case I have follow up questions (like ChatGPT chat UI).

The cool thing is that Anthropic injected in Claude's system prompt to always look up its own documentation when the user asks for a question about itself.

So it has the context.

Now I can finally always understand what each feature does and how to use it!

Next step is to automate it, so every time the Github Changelog page changes I get notified via Telegram and I can see the artifact instantly.

If there's enough interest I'll include you in the automation.

Digital Experience Director | Helping you put experimentation at the heart of your business | Top Experimentation Influencer

My career has been driven by a singular obsession: fundamentally changing the way the business world makes growth and innovation decisions. For nearly two decades, I've forged a unique path using data and experimentation to ignite digital innovation and elevate customer experience.

While the term 'experimentation' has gained traction, I've observed a profound disconnect in its application. Too often, it's relegated to superficial A/B testing or seen as a tactical tweak, failing to deliver its true potential as a strategic driver of growth. This narrow focus leads to siloed learning, unquantifiable investment, and continued reliance on opinion and guesswork for critical business decisions.

This is why I champion Experimentation-Led Growth (ELG). At its core, ELG is about moving beyond mere 'optimisation' to build robust, evidence-driven operating systems for sustained business impact. It's about empowering organisations to de-risk ambitious innovation, accelerate learning velocity, and generate compounding commercial outcomes. My work focuses on integrating Growth Experimentation Systems & Engineering – connecting the strategic vision, the operational infrastructure, and the customer insights to ensure every investment drives tangible, measurable progress.

My unique blend of agency, client-side, and management consultancy experience at senior levels has equipped me with a holistic view of the digital landscape. From leading product analytics for Visa Checkout and building high-impact product discovery teams at Sky, to owning the P&L for front-end Digital Product at Boohoo Group, as well as scaling a digital experience consultancy from scratch, I've consistently applied an experimentation mindset to unlock significant commercial value.

I partner with visionary leaders – VPs of Growth, Product Directors, Digital Directors, and C-suite executives – who are determined to move past the limitations of traditional approaches. If you're looking to transform how your teams learn, ship, and grow; if you're seeking to embed genuine evidence-based decision-making across your organisation; or if you want to unlock step-change velocity and impact from your digital investments, let's connect. I'm keen to share insights and explore how a Growth Experimentation approach can redefine your trajectory.

Director, Digital Experience Services

90% of all changes made to websites are based on opinion and are a waste of time and money because…

It is impossible to know 1000s of customers
Your opinion is deeply biased
You can’t rationalise the irrational

Regardless of the size of your business, the answer is to put data and experimentation at the heart of your development operations. 

We help you do that. 

We take the guesswork out of decision making and provide consultancy and training, systems and frameworks, and experimentation agency services to help you reach your full growth potential.

The hot topic in our industry right now is Agentic Synthetic Testing.

Imagine this: You upload two designs. The system spins up 100,000 AI agents. It gives each one a backstory: "You are a 54-year-old from France, low digital literacy, poor eyesight, looking for a bargain." It runs the simulation. It tells you Version B won. It takes 5 minutes.

No traffic needed. No waiting. Instant statistical significance.

This technology is incredible. It is coming. And it will be valuable 𝗮𝘀 𝗹𝗼𝗻𝗴 𝗮𝘀 𝘆𝗼𝘂 𝘂𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱 𝘄𝗵𝗮𝘁 𝗶𝘁 𝗿𝗲𝗮𝗹𝗹𝘆 𝗶𝘀.

If you treat this as "proof," you are making a mistake.

An AI model is a probability engine trained on what has already happened. It aggregates the "average" of the entire internet. When you test with synthetic users, you aren't testing reality - you are testing against a massive database of heuristics and best practices on steroids.

You are optimizing for the average. You are engineering mediocrity.

Use it for speed: Use it to squash bugs, check accessibility, or filter out terrible ideas before they launch. Use it if you don't have the volume of traffic to do real tests. 

Don't use it for truth: It cannot predict the irrational, messy, emotional behavior of a real human being reacting to a new market condition or a brand new innovation.

Synthetic testing is a map. It is not the territory. By all means, use the map. But don't forget to look out the window at the real world occasionally.
