  Building the AI Distribution Layer for 5000+ Banks, with Fiserv Co-Head of Financial Solutions Srini Krish 10.08.2026 40min

  In this episode, Lex chats with Srini Krish — Co-Head of Financial Solutions at Fiserv, one of the original fintechs, in business for nearly five decades and sitting at the intersection of commerce and banking. Lex and Srini discuss how Fiserv acts as the technology backbone for 5,000+ US banks and credit unions that lack the wherewithal to match JPMorgan or Wells Fargo on their own, and how the firm is packaging AI into that distribution layer through Agent OS and partnerships with OpenAI and Anthropic. Srini lays out his four-bucket framework for enterprise AI - better client service, internal productivity, AI embedded in products, and a platform banks can use to build their own agents - and explains why money demands deterministic outcomes rather than probabilistic guesses, keeping a human in the middle as commercial loan underwriting compresses from weeks to hours. They explore the competitive race against challengers like Mercury and Ramp, the mainframe that has outlived thirty years of obituaries, and where power sits between the AI labs and their distribution channels once inference commoditizes.

  How Perplexity's Computer Is Replacing the Family Office, with Perplexity Finance’s Jeff Grimes 20.07.2026 49min

  In this episode, Lex chats with Jeff Grimes — who is Head of Live Events Products at Perplexity, the AI company that has evolved from an "answer engine" into an "agent platform" built around Perplexity Computer, its multi-agent digital worker. They discuss how Perplexity has shifted financial research from the how to the what, letting a user describe an outcome in a single sentence while Computer orchestrates 20+ frontier models, direct tool calls to licensed live data, and finance-specific skills to produce the artifact. Jeff explains the enterprise strategy behind traceability - the north star that 100% of every quantitative figure traces back to its source filing - alongside bring-your-own-license connections via MCP and the consumer "personal CFO" vision powered by Plaid. They explore what 5x revenue growth on a 34% headcount increase signals for finance jobs, and why the future looks like a 24/7 family office that proactively surfaces and, with permission, executes financial actions for everyone.

  Inside the $1B-a-Day Stablecoin Market Maker for 1,500 Institutions, with B2C2's Cactus Raazi 22.06.2026 43min

  In this episode, Lex chats with Cactus Raazi — CEO Americas at B2C2, one of the original and largest institutional market makers in digital assets, serving roughly 1,500 institutions and pricing across more than 40 exchanges globally. They discuss what a market maker actually does, how balance sheet and signal generation underpin roughly $1 billion a day of stablecoin flow at B2C2, and why the two extremes of crypto market making - riskless principal aggregation versus proprietary alpha - produce very different client outcomes that buyers rarely understand. Cactus explains B2C2's 18-month bet that the Circle-versus-Tether debate would give way to a multi-issuer world, the launch of its PENNY product for instant zero-cost cross-stablecoin swaps, and they explore why programmability is the next frontier for digital dollars, why US capital markets have almost no structure for funding genuine risk-taking businesses, and whether the current combination of scale, speed, and complexity makes this the hardest investing environment Wall Street has ever faced.

They discuss how Marqeta's separation of bank, processor, and brand armed fintech's largest winners across buy now pay later, on-demand delivery, neo-banking, and expense management with the Lego blocks to build their own card programs. Mike explains how the company's growth is shifting from enabling new use cases to displacing volume on legacy bank platforms, and they explore why card issuing is going multinational, what the agentic commerce wave actually requires to clear security and behavioural hurdles, and how Marqeta's continued growth runs through embedded finance, real-time personalisation, and the forced modernisation of the banks themselves.

Evan explains Yuma's role as the institutional gateway to Bittensor through its validator, accelerator, and asset management products, and they explore why the concentration of AI in OpenAI and Anthropic is a systemic risk, and whether Bittensor's future extends beyond AI into a broader coordination engine for decentralised work.

  How Alpaca built the API brokerage for 300+ global fintechs across 45 Countries, with CEO Yoshi Yokokawa 05.03.2026 46min

The conversation begins with their shared experience at Lehman Brothers during the 2008 financial crisis, where Yoshi worked in fixed income securitization and learned that even when market participants sense a bubble, they keep dancing because timing the exit is impossible. After Lehman's collapse, Yoshi pursued entrepreneurship, building a computer vision AI company acquired by Kyocera before founding Alpaca in 2017. Initially inspired by Robinhood, Yoshi pivoted after experiencing firsthand the friction of accessing brokerage infrastructure—realizing the deeper opportunity was building API-first brokerage rails for developers. Today Alpaca powers 9 million accounts through 300+ partners across 45 countries, recently raising $150 million at a unicorn valuation. The discussion explores how Alpaca follows Robinhood's product roadmap to anticipate partner demand, the challenges of adding crypto, and Yoshi's thesis that finance is undergoing a generational shift from digital to on-chain operations. Lex shares examples of legacy infrastructure dysfunction—from faxing PDFs to TD Ameritrade in 2012 to the Synapse collapse caused by manual CSV uploads—illustrating why Alpaca built its own custody and ledger systems as a path to competing in the $350 trillion global securities custody market.

  Building DeFi's $25B Liquidity Engine, with Curve Founder Michael Egorov 05.01.2026 48min

  In this episode, Lex speaks with Michael Egorov - Founder of Curve Finance and YieldBasis. Kicking things off about his journey from experimental physicist to founder of Curve Finance and YieldBasis, highlighting how theoretical physics concepts influenced his creation of financial invariants in DeFi protocols. Curve pioneered fully automated concentrated liquidity for stablecoins and introduced veTokenomics, a governance model rewarding long-term commitment with voting power and protocol fees. Egorov defends veTokenomics against criticisms of unlock-driven volatility, citing that most CRV locks average over 3 years and behave like permanent commitments. YieldBasis expands Curve’s approach by offering impermanent gain strategies to counter impermanent loss in volatile markets like Bitcoin, aiming to scale toward a $50B market ceiling. The discussion closes with reflections on DeFi token market structure challenges and Egorov’s call for protocols to connect token value to real economic flows by activating fee-sharing mechanisms.

  How to Invest in the best Crypto Funds, with Matthew Le Merle CEO of Blockchain Coinvestors 11.08.2025 52min

  Lex chats with Matthew Le Merle - CEO of Blockchain Coinvestors, a leading blockchain and AI fund-of-funds. He reflects on the limitations of large institutions in adopting disruptive technologies and why he chose to back innovators over incumbents, using stablecoins as an example of asymmetric value creation. Le Merle explains his evolution from angel investor to institutional LP, highlighting the benefits of leveraging top-tier venture capitalists’ expertise in inefficient early-stage markets. He outlines the psychological challenges of venture investing, where failures appear early and outsized wins often take a decade, contrasting this with the faster liquidity but higher existential risk in token markets. Finally, he critiques institutional allocators for over-relying on efficient markets, under-allocating to venture despite its role in driving future value, and positions his strategy as fully committed to early-stage blockchain and AI as the highest-returning segments. NOTABLE DISCUSSION POINTS: 1. Innovation Threatens Incumbents, Benefits Disruptors: Major technological shifts, from the internet to blockchain and AI, create winners and losers. Incumbents often resist disruptive change because it threatens existing revenue models, while nimble startups and tech-first companies can rapidly capture new market opportunities. 2. Venture Success Requires Navigating High Failure Rates: In early-stage investing, most portfolio companies will fail, often within the first 3–4 years. Returns are driven by a small number of outsized successes, usually via acquisitions rather than IPOs, requiring patience, resilience, and a disciplined investment strategy. 3. Inefficient Markets Offer the Greatest Asymmetric Upside: Early-stage venture and emerging technologies like blockchain and AI are inefficient markets where superior access, insight, and execution can generate returns far above those available in traditional, efficient markets like public equities or bonds.
