If you are reading this, then the first gate of my mentor funnel is passed. Thank you. 🙏 I follow a simple framework for my work-life style: Learn, make an Impact, have Fun, and be Empathic (LIFE). Over the last few years, I have been a part of fast-growing businesses that are capital efficient and growing by +50-100% YoY in Revenue. The adventures I succeeded in during this crazy startup experience are: – establishing data-driven product culture – creating a product-led growth unit (PLG) – building the business operations department from the ground up – fixing churn – architecting data infrastructure and developing a business intelligence system – optimizing the Freemium model, creating more revenue through the experimentation process – other small missions that strengthened me as an architect Feel free to grab a slot with me 📈

  Conversion rate optimisation

  You have a product. Leads are not converting. The next step is to look into your funnel, find the gaps, and define hypotheses based on the research you did with the dropped off users.

  Customer success

  When we created product funnel for PandaDoc I was involved in a strategy for churn. Another word for churn is success. Winning at churn is not possible without setting the right process for the Customer Success team. Looking into starting your own success team?

  Design / UX

  I follow simple rule here: one-click action — hide complexity behind the scene. I apply new techs to enable this rule. This is especially important when you create product-led growth — replacing a step in the critical path increases conversion rate. Why adding cognitive load on a human?
