Skills

As an entrepreneur and devoted problem-solver, I thrive on tackling technical issues, design challenges, and business problems. I genuinely enjoy delving deep into understanding the problem to its fullest extent - exploring the painful consequences and identifying the root cause.

This approach is both a blessing and a curse: A blessing for colleagues and partners who value critical thinking and seek the truth, yet a curse for those who are intellectually lazy and unwilling to go the extra mile.

Over the past decade, my mindset has evolved through collaborations with various startups and the founding of three ventures. Time and time again, these experiences have reinforced the same invaluable lesson:

Love the problem, not the solution!
 

Clients have hired me for the following use cases/problems:
  • Product strategy: Specify the key problem, the target customer, and their willingness to payž
  • Product development: Take a product from 0 to a successful market launchž
  • Customer Insights: Understand the reason WHY your customers bought your product, as their reasons likely differ from your assumptions.
