Daniel Wulf

For founder-led D2C and digital brands

Your growth problem usually isn't where you think it is.

Most growth problems sit between strategy, marketing and tech, where specialists hand off. I've spent ten years on all three, so I don't.

30 minutes, my honest take.

Floor 1 / Strategy · Top floor

Strategy

Strategy from someone who knows how to build it. I zoom out to the whole business, zoom in on the one thing capping it, and plan only what your team can actually ship.

The big picture

I know where the pipes run

Specialists know their own room. I've worked on every floor, so I know where the pipes run between them, and which one leaks into the next. Each floor makes the others sharper: the code keeps the plan honest, the margin keeps the ads honest, the plan keeps the code small. It's also what clients mention most.

The constraint

Find the one thing capping growth

Founders hire for the symptom they can see: weak ads, tired copy, a slow site. The cause usually sits on another floor. An offer with no reason to upgrade, a category the market doesn't get, attribution that credits the wrong ads, a channel that never fit. I go into the detail until I can name it, before anyone pays for the wrong fix.

The plan

A plan written by the person who could build it

I know what each move takes to build, so the 90-day plan is scored on real effort. Every move weighed against its return, the few that pay back this quarter kept, what to stop written next to them. Margin per product decides what gets scaled, fixed or killed, and sometimes the answer is to spend less. Your team knows what to do on Monday and what to leave alone.

Floor 0 / Marketing · Ground floor

Marketing

Most marketing breaks at the handoffs: the ad promises one thing, the page says another, the email a third. I run it as one line, from the first ad to the second purchase.

The message

A reason to buy, in your customers' words

When a good product gets undervalued, the offer is usually the lever. I rebuild it from what your buyers actually say: the value ladder, the mechanism that explains why it works, the position against the category. It gets decided once and carried into every ad, page and email, so nobody downstream invents their own version.

The traffic

Ad platforms grade themselves. I grade on your margin.

I work from your margin: a target CPA per product, budgets sized to what you can actually deliver, and the account architecture, kill rules and retargeting that follow from those numbers. I design the account and read it every week; your media buyer runs it.

The funnel

Catch the people who aren't ready yet

Ads that point straight at a product page pay for clicks from people still deciding. I design top, middle and bottom together, with a front door for everyone still making up their mind: a guide, a quiz, a video, an online summit. Launches feed it, and the evergreen funnel keeps selling after the spike. I build the pages myself, advertorials, VSLs and sales pages included.

The list

Where the second purchase comes from

The first sale often just pays back the ad. The second one is the profit, and it comes from the list. One tag and segment structure your team can read, lifecycle and post-purchase flows, recurring campaigns to the warm list, and a soft opt-out that keeps fatigue from burning it. Your list becomes a channel with a number attached.

Floor -1 / Tech · Basement

Tech

Marketing tools usually die the week the person who set them up leaves. Down here are the machines that keep running after I've left the building, and every one is live today, at a client or in my own shops.

The systems

Code for the boring parts, AI where it has to think

AI, processes and skills wired into your team's daily work. Plain code handles everything that should come out the same every time, the model judges only where judgement is needed, and a person signs off before anything ships. Your product facts and customer language live in one place, so every draft starts from them. It's yours to keep: the code and the data stay on your side and keep running when I'm gone.

The software

Launch without a dev ticket

Custom software for creating and publishing. A funnel builder your non-technical team uses to build funnels and push the emails, publish flows for recurring site edits, and sales pages and quizzes deployed headless into Shopify or WordPress, so every order lands in your own stats. Through my studio, pages go live within 72 hours of greenlight and complete inputs.

The check

A second opinion on what others build

Your agency reports one ROAS, your shop shows another, your developer says six weeks. I read the setup underneath: tracking, attribution, the code, the estimate. I split clicks from view-through and catch the report that silently drops a channel. You hear what's off and what it should take; your team or your agency fixes it.

The annex

I run every floor for myself first

Yes, a strategist with a shop for people who make their own sausage. My own projects are where I hold strategy, marketing and tech on my own money, and where most tools on these floors ran first. They get better with every client after. You start where the last one finished; what carries over is the method, never the data.

My shops

My shops

Charcuteria in German and Wurst Circle, its English twin: 31 products, books and courses. I built all of it and steer it: the shop and its stack, paid ads, and organic search from a blog and 250+ recipes in two languages, plus 254 process videos indexed by my own pipeline. Charcuteria alone drew close to a million visits in the last twelve months, over 60% from organic search. Support and the newsletter run on a system one non-technical person handles day to day.

nodacop

nodacop

My studio. It reads a brand's ads, angles and gaps before we've ever spoken, then delivers finished, deployed assets.

My consulting OS

My consulting OS

My practice runs on a brain I built: ten years of methods, every client lesson and everything I read, from art to biology, linked in one place. That's how an essay on pruning apple trees can end up shaping which product line you cut.

3,200+ commits across these systems in 2026. I sell what I run.

Notes from the work

Three long ones, where I held every floor for years. A few lines each, from far more work. The names are public; their numbers stay with them.

  1. 2018-2026

    Fairment

    A German gut-health brand. I first worked with the founders at Paleo Lifestyle in 2016.

    Strategy
    90-day sprints for eight years, through the pivot from fermentation to spore-based probiotics.
    Marketing
    The mechanism and a 9-step belief chain behind every ad, advertorials and VSLs, full funnels per problem segment.
    Tech
    An asset factory with one product brief as the single source of truth, a content cockpit for publishing, and an AI-assisted training system for the team.

    What stuckA fermentation brand became a probiotics brand, with the funnels and the team to sell it.

  2. 2018-2026

    Medumio

    A health-education group running free online health summits.

    Strategy
    The free summit as the front door, and the warm list as the asset, cultivated on a calendar.
    Marketing
    A summit funnel and email library reused across every event, an evergreen lead system with three doors by effort, recurring campaigns to the warm list.
    Tech
    A CRM collapsed from hundreds of tags into one hierarchy, and in 2026 the content factory their editors use to build funnels without a developer.

    What stuckEvery new summit launches on the same funnel and email library, and the warm list pays on a calendar between launches.

  3. 2024-2026

    Viktilabs

    The supplement brand that grew out of Medumio, built to sell without the summit list.

    Strategy
    Which products earn paid traffic, picked on search volume, price, margin and repeat value.
    Marketing
    An advertorial funnel per product across Meta and Google, tested with kill rules from day one.
    Tech
    Automated data and reporting, so spend decisions rest on numbers the team trusts.

    What stuckPaid Google became the strong channel, and the shop sold without leaning on the summit list.

Shorter engagements

  • Sipgate2022Repositioned a cloud-phone product as the opposite of the old office phone system, and suggested slowing the spend until the funnel could carry it.
  • WeSendit2023-2024A file-transfer service whose free tier gave people little reason to upgrade, so I advised against spending more on copy.
  • Symedic2021-2022Scaled a chain of local test centres through Google and Meta ads, with budgets set by what each centre could handle, and advised against scaling a new line once the model came out negative.
  • KakaoMischa2026A ceremonial cacao brand: a full status-quo audit and dashboard, a roadmap that put the basics before scaling, and help hiring the team to run it.

Worked with

Since 2016. The longest run: the same founders for 10 years, across 2 companies.

How I work

I take few clients and say no fast. It works best when your product already sells, your team can implement, and you're open to changing how things run. The first conversation tells both of us whether this runs without drama on either side.

  1. Zoom out
  2. find the constraint

Who does whatDaniel Wulf
How one person does all three? I'm a nerd. I'm a team of one, plus my studio for production. I build the system: the strategy, the funnel and the custom tools underneath. Your team runs it internally, and I make sure they can before I step back. If you need more hands, I'll help you hire them: one 45-minute interview that separates doers from order-takers, and a lead marketer mentored until nothing waits on me.
Rhythm
One weekly call, 60 minutes. Everything else is async, with a reply within one working day, in English or German.
What to call me
Fractional CMO, external marketing consultant, marketing advisor: call me whatever fits your org chart. I also answer to Mr. Wulf. I solve problems.
Terms
Month to month. If it stops paying for itself, end it at any month-end and keep everything I built: code, data, every access.

What I don't do

  • Jump on spontaneous calls. Outside the weekly call, writing is usually faster anyway.
  • Run your ad accounts day to day. Your team keeps its hands on the controls.
  • Manage your agencies or chase their deliverables. I'll coach whoever does.
  • Become your interim owner or your presenter. Decisions stay with whoever carries the P&L.
  • Take on product, legal or finance work. I'll tell you who to call.

Tell me what's stuck. I'll tell you which floor I think it's on.

In 30 minutes you get my first read: which floor, and what I'd look at first. If we work together, it's month to month and you keep everything I build.
