How Interplay Wins Competitive Allocations

How do you balance power-law outcomes with real risk management while building a durable venture franchise? In this episode, I speak with Mark Peter Davis (MPD) — Managing Partner of Interplay, entrepreneur, author, podcaster, and one of New York’s most active early-stage investors. We discuss how Mark’s philosophy of investing has evolved over 20 years in venture, why VC psychology is so different from other asset classes, and how he manages for both outliers and consistency across vintages. Mark breaks down secondaries, constructing high-access portfolios, founder relationships, narrative risk, the role of operational support, and why grit compounds just like interest.

Highlights:

• How 20 years in venture reshaped Mark’s thinking on risk, liquidity, and exit timing.
• Why early VCs get caught in the “TechCrunch punch” and over-index on hope.
• Power laws vs. portfolio consistency — why vintages swing and how Mark mitigates volatility.
• How secondaries, tenders, and mid-market PE can drive liquidity for the “middle 80%” of winners.
• The “tweener rule”: why Interplay often sells ~50% when outcomes are unclear.
• Incentive alignment between GPs and LPs — and why building a long-term institution changes behavior.
• Avoiding narrative traps: why founder behavior and fund construction matter more than storytelling.
• Brokerage-model VC vs. operational-institutional VC — and why the difference is huge.
• How soft commits, goodwill, and reference strength drive proprietary access.
• Entrepreneurship patterns: the “500 problems” every startup faces.
• Why you can’t learn entrepreneurship in a classroom — only through reps.
• The compounding effect of grit and staying in the game long enough.
