LinkedIn Co-founder Konstantin Guericke on LinkedIn's Early Days, Mentorship and Viral Growth

About this episode

LinkedIn generates over $10 billion in annual revenue today, counts more than one billion users, and is the most relevant social business network globally. But did you know there's a German LinkedIn co-founder?

As LinkedIn's co-founder, Konstantin Guericke was responsible for marketing the then newly founded startup. This positioned him to set the crucial course for viral growth that made LinkedIn one of the world's 10 largest social networks with over one billion users. Today, he mentors Stanford students in the heart of Silicon Valley.

LinkedIn's Early Days: Experience vs. Potential

In LinkedIn's early days, the founders faced a central question: Should they hire experienced employees or bet on potential? This decision was formative for building the team and developing the company. Konstantin provides insights into the founders' mindset and explains how they made these important personnel decisions.

Viral Growth: Engineering Growth Into Your Product

One of the key factors behind LinkedIn's success was viral growth. Konstantin explains how to deliberately "engineer" viral mechanisms into a product and which strategies are particularly effective. These insights are especially valuable for founders of social networks or platform-based business models.

Mentorship: What Makes a Good Mentor?

As an experienced mentor, Konstantin shares his perspective on effective mentoring. He explains what qualities make a good mentor and how both mentors and mentees can get the most out of this relationship.

A Special Setting: Podcasting While Hiking

This episode was recorded on the Stanford Dish Hiking Trail, a popular hiking route for many tech leaders from Silicon Valley.
