Diversification versus concentration in portfolio construction

Dan Gray is the Head of Insights at Equidam.

If you’re a tech and investing nerd like us, you’ll love this conversation. We cover everything Dan’s learned reading dozens of academic research papers on startups and venture capital, debunking many popular narratives of the industry.

We talk about the dangers of pre-mature startup scaling, the importance of origination stage investing, the concept of startup catering and why so many startups look the same, and the role of mega funds play in the ecosystem.

We also discuss what the data says about concentration vs diversification, what VC’s get wrong about pattern matching, and why pivoting is more valuable than you think
