I.
How we work together

Three months in. Then a decision.

One engagement, three months minimum. That's the honest floor for operator work. Anything shorter doesn't give campaigns time to cycle or metrics time to stabilise. Here's what each month looks like. Works for PLG, SLG, or hybrid motions.

II.
On fit

I work best with a specific kind of founder.

Not every B2B SaaS is my wedge. Here's who this works for, and who it does not.

Right fit

  • B2B SaaS, $1–5M ARR, PLG or SLG motion (or hybrid)
  • Founder still running marketing, no senior marketing leader on board yet (possibly a junior hire in place)
  • One channel working, stuck on how to scale it or add the next
  • SaaS or data tools serving B2B buyers
  • Ready for shipped work, not more strategy discussion

Not the right fit

  • Pre-product-market-fit or pre-revenue companies
  • Pure enterprise with year-long sales cycles and custom contracts
  • Companies with a full in-house marketing team already
  • Consumer products such as B2C apps and marketplaces
  • Founders looking for a weekly strategy advisor
III.
How a sprint runs

Thirty days, one lever, shipped.

Sprints are structured. You see the plan in week one, artefacts shipping by week two, and the whole package live on your site by day thirty. No mystery, no timesheets.

i.
Week one
Diagnostic & scope lock

Half-day of your time, async via Loom and shared doc. I confirm the lever, define the deliverable, and write the plan.

ii.
Week two
Draft + build

First outputs ready for review. You see pages, flows, or content in draft. We refine in one pass.

iii.
Week three
Ship + iterate

Work goes live on your site or in your stack. I watch the early signal and adjust based on what happens.

iv.
Week four
Handoff + roadmap

Full handoff document, metrics baseline, and a 60/90 day follow-up plan. You keep everything.

IV.
About

A marketer who ships.

Thirteen years in B2B.
Five deep in SaaS.

Over the last two years I led marketing at ScraperAPI (saas.group), scaling ARR from $5M to $8M while building the company's first full-stack marketing team from scratch. Organic traffic grew 60% through a disciplined SEO and content program.

Before that, I led product marketing at InvoiceOcean, a multi-country invoicing SaaS at multi-million ARR, where I managed a paid media account of roughly $200,000 per month alongside launching a new product into the Ukrainian market. I've worked both sides of the motion, PLG self-serve funnels and SLG pipelines with AEs and long cycles, and shipped across SEO, content, lifecycle, paid, and positioning.

Now I work with a small number of founders at a time, focusing on the ones scaling past the first million and hitting the wall where the first working channel stops producing. If that's you, the two offers above are how I help. If we're a fit, we'll know in the first exchange.

Common questions

Questions founders keep asking.

Straight answers to what usually comes up in the first call. If yours isn't here, send it over. I'd rather be honest up front than stretch something that isn't right.

How is working with a fractional growth operator different from hiring a full-time marketer? +

A full-time marketer is a long commitment. 12 to 18 months minimum (onboarding included) before you know whether the hire was right. Growth hires at small SaaS companies fail roughly 50% of the time, usually because the founder hired execution before figuring out which levers to pull.

Fractional work flips the order. In 30 to 90 days you see which levers move the needle, you get shipped work on your site (not a strategy deck), and you build a clear spec for the full-time hire when you're ready. Less risk, faster signal, lower cost.

Isn't it cheaper to just hire someone full-time? +

On paper, a junior growth hire looks cheaper. Then you add the full cost: salary, equipment, tools, recruiting fees, ramp time (3 months before real output), and the management overhead they need from you.

A fractional operator gives you senior judgment, shipped work from week two, no ramp, and no management burden. For a company at $1 to $5M ARR that isn't ready for a VP of Marketing, this is often the highest-quality option for the budget you have. When you're ready for a full-time hire, I'll help you write the spec and hand off cleanly.

How many clients do you work with at once? +

Two at most. That's how I keep the work hands-on instead of drifting into status updates and delegation. If a third client comes in, they go on a waitlist or I route them to a trusted colleague.

This means I say no to work regularly, and it's why the clients I do take on get real attention rather than a few hours squeezed into a booked calendar.

How do you decide who to take on? +

I look for four things: B2B SaaS at $1 to $5M ARR; a PLG or SLG motion I've worked in before; one channel that is already working (so we have something to scale, not start from zero); and a founder who wants to ship the work, not just discuss it.

If we're not a fit, I'll tell you in the first call, often with a recommendation for someone who is. That's better for both of us than a mismatched engagement.

How long do engagements usually last? +

Sprints are 30 days, flat-fee, one defined lever. Retainers are three to six months minimum. That's the honest floor for ongoing operator work, because anything shorter doesn't give enough time for campaigns to cycle and metrics to stabilise.

Most retainer clients extend past six months. Some transition to a lighter advisory retainer once their in-house team is in place. A few graduate entirely and hire full-time, which is usually the goal.

Do you work with US-based companies, or only Europe? +

Both. I'm based in Warsaw and available for synchronous work with US Eastern Time mornings (my afternoons). Weekly calls work fine in that window. I don't take roles requiring late-evening overlap past 6 PM Warsaw time. That is for my own sustainability, and it works for most founder-led SaaS companies.

What happens on the discovery call? +

Thirty minutes, free, no pitch. You tell me where you're stuck, I ask questions, and by the end you'll get an honest read on whether a sprint or retainer fits, what I'd prioritise, or whether someone else would serve you better.

No follow-up pressure, no sales sequence. If you're a fit and want to proceed, we'll scope it together in a second call.

What should I have ready before our call? +

Nothing formal. A short note on where you are (stage, ARR, team size) and what you're stuck on is enough. If it helps your own thinking, a link to your site and any metrics you already track tells me most of what I need.

What I don't need: decks, detailed briefs, or a polished problem statement. The call is for figuring out what matters, not for me to review homework.

How do you think about measuring success? +

Differently for sprints and retainers. A sprint has one defined deliverable shipped by day 30, and that is success. Whether it moves the downstream metric is usually visible in 60 to 90 days, and we agree upfront what we're watching.

For ongoing work, success is a north-star metric you already care about (new MRR, trial-to-paid, organic traffic, pipeline) with weekly leading indicators we can influence. I won't promise outcomes I can't defend, and I'd rather under-commit and outperform than sell on hope.

Thirty minutes, no pitch. We'll talk through where you're stuck, what's been tried, and whether a sprint or ongoing operator work would move the needle. If I'm not the right person, I'll tell you, and often point you to someone who is.
