David Siegel, Former CEO of Meetup & Investopedia, on Solving the Loneliness Crisis, Rescuing Meetup from WeWork, and Why Israelis are Happier than Americans

On this episode of Invested, Michael Eisenberg sits down with David Siegel, former CEO of Meetup, former CEO of Investopedia, former President of Seeking Alpha, author of Decide & Conquer, and founder of the Israel Tech Mission. David has spent more than 25 years building and leading technology companies, but his most passionate mission has been tackling one of society’s fastest-growing challenges: loneliness. As CEO of Meetup, he led the global community platform through a dramatic turnaround, transforming it from a money-losing business into a profitable company while helping millions of people connect around shared interests, passions, and causes. In this wide-ranging conversation, Michael and David explore the roots of the loneliness epidemic, why social media and screens may be making people less connected than ever, and what can actually be done to rebuild community in modern society. David shares lessons from leading Meetup through COVID, selling multiple companies, scaling organizations, and retiring from full-time operating roles at age 50. More on in the episode: Why loneliness is more dangerous than smoking How Meetup grew into a global community platform spanning nearly every country The surprising origin story of Meetup after 9/11 Turning around a WeWork company losing $20 million annually Why social media increased loneliness instead of reducing it The cultural and technological drivers behind rising social anxiety Leadership lessons from building and selling companies The power of decision-making and creating your own luck Israel Tech Mission and bringing global tech leaders to Israel Why David believes mandatory national service is the best solution to the loneliness epidemic What Israel gets right about meaning, community, and belonging David Siegel is the former CEO of Meetup, the largest platform for finding and building local community. He has had two exits over the last six years where he drove investor returns of 5x and 7x. Prior to Meetup, David served as CEO of Investopedia and President of Seeking Alpha. Today he advises CEOs, serves on boards, teaches strategy and scaling at Tel Aviv University, hosts the Keep Connected podcast, and leads the Israel Tech Mission, which has brought hundreds of global technology executives to Israel.

On this episode of Invested, Michael sits down with Oren Zeev, a one-man VC with $2.7 billion AUM. Over the last three decades, Oren has quietly built one of the most remarkable track records in venture capital, backing category-defining companies including Audible, Chegg, TripActions/Navan, Tipalti, Houzz, Riverside, and more. Operating without a traditional partnership or even an office, Oren runs Zeev Ventures largely from Café Venetia in Palo Alto — relying on speed, conviction, and founder relationships to make investments that others often miss. In this candid and wide-ranging conversation, Michael and Oren unpack the psychology of venture investing, why most partnerships create “negative feedback loops,” and why missing a great company is far worse than making a bad investment. Oren explains how he evaluates founders in a single meeting, what makes a company defensible in the age of AI, and why adaptability matters more than code. They also go deep on the incredible story of Navan: from an accidental street encounter that sparked the investment, to existential battles with Delta Airlines, COVID reducing revenue to nearly zero overnight, near cash collapse during hypergrowth, and surviving one of the worst IPO receptions of 2025. The conversation also explores: Why AI is both destroying and strengthening moats The mental model behind successful venture investing Why proprietary data matters more than ever Lessons from Chegg’s collapse in the ChatGPT era Founder-led companies vs. corporate “dinosaurs” Why venture capital is entering its greatest era Israeli founders, resilience, and building global companies The dangerous obsession with unsustainable hypergrowth Oren Zeev is the founder of Zeev Ventures, a solo venture capital firm managing billions in assets and backing some of the most important technology companies of the last two decades. Prior to founding Zeev Ventures, Oren was a General Partner at Apax Partners. He has been repeatedly recognized as one of the world’s top venture investors and is known for his concentrated, high-conviction investing style.

On this episode of Invested, Michael Eisenberg sits down with Elad Raz, Founder and CEO of NextSilicon, for a deep dive into the future of compute - and why the AI revolution may be bottlenecked by the very chips powering it. In this technical and provocative conversation, Michael and Elad unpack what it actually means to “reinvent compute,” why today’s dominant architectures from Nvidia, Google, and Amazon may be fundamentally limited, and how NextSilicon is taking a radically different approach—one that replaces traditional CPUs and GPUs with a dynamically reconfigurable chip architecture. Drawing on Elad’s background in elite Unit 8200 and decades of experience in high-performance computing, he explains why most AI chips are solving for the present—not the future—and why the real breakthroughs may come from entirely new paradigms like dataflow computing. He also shares bold claims about performance, including running workloads up to 10x faster at a fraction of the power, and discusses NextSilicon’s role in building next-generation supercomputers for U.S. national labs. They discuss: - Why the world is entering the “age of compute” - What Nvidia—and the rest of the industry—may be getting wrong - The real bottleneck in AI: memory vs compute - Why faster AI often means dramatically higher cost - The difference between training, prefill, and inference architectures - Why future AI models may look nothing like transformers - The economics of chips, data centers, and trillion-parameter models - How NextSilicon’s architecture could reshape both HPC and AI Elad Raz is the Founder and CEO of NextSilicon, a deep-tech company redefining high-performance computing and AI infrastructure. A graduate of the IDF’s elite Unit 8200, Elad brings more than 20 years of experience in technology, entrepreneurship, and executive leadership. Before founding NextSilicon, he founded Integrity Project, which was acquired by Mellanox Technologies in 2014. Elad resides in Ramat Gan, Israel, with his wife and three sons. If you want to understand where AI infrastructure is really heading—and why the next wave may not belong to today’s incumbents—this episode is essential viewing.

On this episode of Invested, Michael Eisenberg sits down with Amir Fischer, a 16-year-old investor, podcaster, and emerging venture capitalist who is building an entirely new investing thesis: teenagers backing teenagers. In this sharp and unconventional conversation, Amir explains how he started investing in public markets at age 10, built a $15,000-a-month ad agency at 14, cold-emailed 3,000 financial titans to launch his podcast, and raised a $2 million venture fund - legally set up in his mother’s name - to back the most exceptional teenage founders in the world. Michael and Amir explore what makes this generation different: growing up with the internet, adapting early to AI, and developing leverage far earlier than previous generations ever could. They also debate whether school is still the best use of time for ambitious young builders, why maturity matters more than intelligence, and how short-form content and algorithms are creating a “Great Bifurcation” between high-agency and low-agency people. They discuss: Why teenagers may be the most overlooked investment category in the world How Amir landed guests like Steve Cohen through relentless persistence Why some of the most talented teens are already working in crypto, AI, and trading The dangers of algorithm-driven short-form content How access to information is reshaping ambition, learning, and opportunity Where elite teenage founders actually come from Why Amir sees himself as a “kingmaker” for his generation Amir also reflects on identity, conviction, and the fear of mediocrity - and why young people should use their age as an advantage, not a limitation. Amir Fischer is the founder of Noar Ventures, a venture fund focused on investing in exceptional teenage founders, and the host of Generating Alpha, where he has interviewed some of the most prominent investors in the world.

On this episode of Invested, Michael Eisenberg sits down with Dr. Eli David, a leading AI researcher, entrepreneur, and one of the most outspoken voices in tech today. In this wide-ranging conversation, Michael and Eli explore the intersection of artificial intelligence, free speech, geopolitics, and the future of global power. From building and selling AI startups to amassing nearly a million followers on X through unapologetically unfiltered opinions, Eli shares why controversy, not consensus, drives both innovation and influence. They dive deep into the current state of AI - why today’s models are fundamentally inefficient, how “woke” training and RLHF shape model behavior, and why Eli believes the future of AI will come from radically different architectures and massive efficiency gains. The discussion expands into the global AI race, where energy - not algorithms - may determine whether the US or China wins. Beyond technology, the conversation turns sharply into politics and society: censorship vs. free speech, the role of social media as the modern town square, the implications of October 7th on global narratives, and why Eli believes the West is at a critical inflection point. They discuss: How Eli grew from AI researcher to viral X personality Why unfiltered speech outperforms polished narratives The hidden biases inside AI models and training systems Why current AI is powerful - but deeply inefficient China vs. the US in the race for AI dominance Free speech, censorship, and the future of online platforms Israel’s role in the global AI ecosystem and talent war Why startups and controversy share the same DNA Dr. Eli David is a leading AI researcher and entrepreneur who has founded several successful AI-based companies. In 2025, the State of Israel selected Dr. David as a national Torch Lighter at the 77th Independence Day ceremony - one of the country's highest civilian honors - in recognition of his pioneering contributions to AI. If you want to understand where AI is really heading - and why the biggest debates around it are no longer technical but ideological - this is an essential and unfiltered conversation.

On this episode of Invested, Michael Eisenberg sits down with Ami Daniel, co-founder and CEO of Windward, for a deep dive into one of the most important global trade chokepoints: the Straits of Hormuz. In this urgent conversation, Michael and Ami unpack how the closure and disruption of the Straits of Hormuz could affect the global economy, oil prices, LNG and LPG exports, container shipping, fertilizers, steel, food supply chains, and the future of maritime security. Drawing on Ami’s expertise in maritime AI and naval strategy, he explores why the Strait of Hormuz is far more than an oil story, and why its disruption impacts nearly every country, industry, and consumer in the world. They discuss: Why the Straits of Hormuz matter to global trade How Iran’s actions could reshape shipping routes, energy markets, and maritime logistics The role of naval power, mines, drones, and maritime chokepoints The ripple effects on Europe, Asia, developing markets, and the wider global economy Why this crisis could have lasting implications for inflation, supply chains, and geopolitical stability Ami Daniel is the Co-founder & CEO of Windward, a leading Maritime AI company transforming global trade through predictive intelligence and big data analytics.

In this special solo episode, Michael Eisenberg shares reflections from Israel during wartime. Speaking from Tel Aviv shortly after a siren sends residents to shelters, Michael offers a firsthand perspective on how Israelis are living, working, and building amid ongoing rocket attacks and regional conflict. At the center of the story is Israel's remarkable ability to produce agency at scale – and the cultural forces that drive Israelis to act, innovate, and support one another even in moments of crisis. Michael also steps back to discuss the bigger picture. As global conflict intensifies and geopolitics increasingly intertwines with technology, he argues that resilience, sovereignty, and technological capability will define the next era. From defense technology and artificial intelligence-enabled coordination to the continued momentum of Israel's startup ecosystem, this episode examines how war accelerates innovation and reshapes global investment and power. Part reflection, part analysis, this episode offers a window into the mindset of a nation under pressure — and why Michael believes Israel's culture of resilience, entrepreneurship, and initiative will play an outsized role in the technological and geopolitical landscape of the coming decade.
