How I Invest with David Weisburd

What happens when one investor sits at the intersection of venture capital, natural resources, AI, space infrastructure, and geopolitics? In this episode, I sit down with Rob Stephens, Director of Investments at Spider Management, to discuss how institutional investors are adapting to a world where private markets are capturing more value, AI is reshaping capital allocation, and the boundaries between asset classes are disappearing. Rob shares lessons from both the GP and LP sides of the table, explains why traditional portfolio construction frameworks may be outdated, and explores how themes like power generation, data centers, space infrastructure, and venture capital are becoming increasingly interconnected. We also discuss emerging managers, co-investments, continuation vehicles, concentration versus diversification, and the future of private markets.

What if the best private equity opportunities are hiding inside businesses that everyone else thinks are too complicated to touch? In this episode, I sit down with Josh Adams, Partner at OpenGate Capital, to discuss why complexity has become one of the firm's greatest competitive advantages. Josh explains how OpenGate built a specialization around corporate carve-outs, why Europe offers more inefficiency than North America, and how operational improvements drive value creation in today's market. We also discuss sourcing, specialization, alignment, decision-making, and why focus has become increasingly important as private equity continues to evolve.

What if the biggest opportunity in private markets isn’t finding the next startup—but owning the next public company years before it ever rings the bell? In this episode, I sit down with Matt Witheiler, Head of Late-Stage Growth at Wellington Management, to discuss how the line between public and private markets continues to blur. Matt explains why companies are staying private longer, why public investors are starved for growth, and how late-stage investing differs from both venture capital and public equities. We also explore IPO markets, valuation discipline, liquidity dynamics, and why the best companies often justify paying up for quality.

What if the biggest investment opportunity of the next decade isn’t AI itself—but the companies building the infrastructure and workflows that allow AI agents to actually do work? In this episode, I sit down with David Blumberg, Founder and Managing Partner of Blumberg Capital, to discuss why he believes agentic AI is still in the first inning of a multi-decade transformation. David explains how AI agents will reshape productivity across industries, why vertical software companies with proprietary data have a major advantage, and how network effects are evolving through AI-powered data flywheels. We also explore the future of work, the rise of AI-native businesses, and why human relationships remain one of the few enduring advantages in an increasingly automated world.

What if the biggest inefficiency in investing today isn’t asset selection—but the fact that most investors still optimize for pre-tax returns instead of after-tax outcomes? In this episode, I sit down with Jeff Bramel, Partner at a16z Perennial, to discuss why real assets remain one of the most misunderstood areas of institutional investing. Jeff explains how structural diversification works beyond traditional portfolio theory, why private real estate behaves differently from public markets, and how tax efficiency can dramatically reshape long-term returns for taxable investors. We also explore opportunistic investing, portfolio construction, risk management, and why real estate may offer one of the largest remaining pockets of structural alpha.

What if the best opportunities in venture today aren’t in new deals—but in existing companies right before an inflection point? In this episode, I sit down with Ryan Moore, Founder of Revenant VC and longtime venture investor, to discuss why he made the shift from primary venture investing to secondaries after more than two decades in the industry. Ryan explains how longer liquidity timelines are reshaping venture capital, why secondary investing is less about discounts and more about information asymmetry, and how founder relationships and insider alignment create the best opportunities. We also explore organizational metabolism, LP evolution, and why small, focused funds may outperform in a world dominated by mega-platforms.

What if the highest-return investments are the ones that reshape the future—not just the ones that fit today’s market? In this episode, I sit down with L.R. Fox, Managing Director of NEXT Global Capital, to discuss why he rejected the traditional path of “build wealth first, give later” and instead built a strategy around impact from day one. Fox explains why capital is a vote for the future, how the best investments often sit outside crowded sectors, and why frontier technologies with real-world impact can outperform conventional venture. We also explore his “buy, build, invest” framework, how he creates entirely new markets, and why resilience—not IQ—is the strongest predictor of success.
