#121 Mirco Grübel: CEO at myster.de and Perpetuo

About this episode

From Corporate CEO to Serial Entrepreneur

Mirco Grübel exemplifies how to successfully leap out of your comfort zone. After years as a CEO in large corporations, he made a pivotal decision at age 30: he quit his secure job and became self-employed.

The Path to Independence

The transition from employed manager to entrepreneur is rarely straightforward. Grübel had to leave behind the security of a steady salary and established structures. However, his experience as a CEO in large companies had equipped him with the necessary tools: strategic thinking, leadership skills, and a deep understanding of business processes.

Success with Business Consulting

His first pillar as an entrepreneur became a business consultancy, which he now runs successfully. This solid foundation enabled him to take further entrepreneurial steps and make calculated risks.

myster.de: Revolutionizing the Trades Industry

For the past year, Grübel has been working on his latest project: myster.de. With this platform, he has set himself an ambitious goal – revolutionizing the trades industry. This is a market with enormous potential, but also with traditional structures and unique challenges.

The trades industry is often characterized by:

  • Fragmented structures
  • Traditional working methods
  • Digitalization challenges
  • Skills shortages

myster.de addresses exactly these issues and aims to transform this industry through innovative approaches.

The Modified Pareto Principle

A special highlight of the conversation is Grübel's variation of the well-known Pareto Principle. The classic 80/20 rule states that 80% of results are achieved through 20% of effort. Grübel's variation of this concept offers entrepreneurs a new perspective on efficiency and priority setting.

This practical wisdom shows how experienced entrepreneurs develop established concepts further and adapt them to their specific needs.

Learnings for Founders

Grübel's journey reveals several important points for aspiring entrepreneurs:

Timing matters: At 30, he had already gained enough experience but was still young enough for big risks.

Gradual diversification: First establish the successful consultancy, then tackle additional projects.

Identify industries with transformation potential: The trades sector is a traditional industry with significant digitalization needs.

Evolve proven concepts: Instead of reinventing everything, intelligently adapt existing principles.

Conclusion

Mirco Grübel demonstrates that the path from employee to successful entrepreneur is possible – if you're willing to take calculated risks while proceeding strategically. His combination of consulting experience and the courage to revolutionize a traditional industry makes him a compelling conversation partner for anyone considering the leap into self-employment.
