About

// Focus, before, shift
01 Focus

I'm Jan, a B2B SaaS marketer with 10+ years across growth, product marketing, and operations. I think strategically and build hands-on. My core lane is customer research and positioning grounded in JTBD interviews. Now executing AI-native, end-to-end. Customer evidence leads, AI accelerates.

02 Before

Before consulting, I led growth at SatisMeter through to its acquisition by Productboard in 2022. Earlier, a string of SaaS roles and a solo explainer-video studio shipping work for 30+ companies. The thread: distill messy reality into something a customer can understand.

03 Shift

Since late 2025 I've gone AI-native, top to bottom: 5,000+ LLM sessions, 15,000+ images generated, Claude Code daily, custom AI assistants grounded in real customer evidence. Buyer's journey analysis that used to take 10 hours per customer now runs in 20 minutes at the same depth.

Words From the People I've Worked With

// LinkedIn recommendations · GrowthMentor reviews

"Jan has joined SatisMeter as Head of Growth and quickly became a key person in the startup. He is an extremely talented and hard-working person. I would work with Jan again, any day."

Jakub Sedláček Co-founder & CTO, SatisMeter via LinkedIn

"Jan is a very thoughtful and analytical marketer. He doesn't take anything for granted. He questions everything and digs deep until he understands how each channel is contributing to the funnel."

Omer Molad Co-founder & CEO, Vervoe via LinkedIn

"Jan is combining his wide technical knowledge with a very detail and perfectionist approach. Whatever he built was a superb. Give him freedom, trust and your time and he will deliver the results."

Zdeněk Pejcel Founder, Mooza Inspire via LinkedIn

"Through customer interviews and surveys, we gathered a huge amount of data that helped us understand how customers think when choosing a CRM tool. We immediately started using the outputs for new case studies and a demo video focused on what matters most."

Jan Korpas CMO, Raynet · Messaging Sprint via Client review

"The static ad creatives were remarkable, to the point where we were questioning how they were even made. The video quality is significantly better than the AI content we've seen competitors put out."

Jan Korpas CMO, Raynet · AI Creative Pilot via Client review

"Jan shared his in-depth process for doing Jobs to Be Done research at his SaaS. The frameworks and the way he organizes customer data in Notion were fascinating to see. He was really generous showing his process to me."

Anna Zaleska B2B SaaS Founder via GrowthMentor

"Jan's understanding of product-led growth, specifically how to talk with, analyse and extract key information from current users is essential for growth optimisation at the execution and product layers."

Alex Sly Marketing Leader, Storacha via GrowthMentor

"Excellent session! Jan had multiple ideas that significantly improved how I was thinking about our strategy. He pointed out a few challenges he saw with our current pricing and business model and why he felt this could be holding back our monetization efforts."

Max Fram-Schwartz Co-Founder, Glimpse via GrowthMentor

How I Work

// Three phases, no guesswork

Guesswork has no place in my methodology. Marketing should be driven by customer evidence and product data. Understanding what's true about customer buying behavior is a human discipline that requires experienced judgment. AI helps with execution across the board, given proper guidance.

01

Understand

Fully understand before acting. Working off wrong assumptions is too expensive.

  • Marketing context audit
  • Analytics audit
  • Customer evidence sprint
  • Competitive landscape
02

Build foundations

Translate evidence into strategy the team can act on. Depth should match the company stage.

  • Positioning strategy
  • ICP & segmentation
  • Messaging framework
  • Channel strategy
03

Execute end-to-end

Execute where the leverage is biggest, based on what the understanding revealed.

  • Website & design system
  • Onboarding & lifecycle
  • Sales & creative assets
  • Content & distribution
