This week on Tech Can’t Save Us, host Paul David is joined by Ignacio Berardi, Co-Founder and CEO of Rexi, an AI-native financial operations platform rebuilding the infrastructure layer beneath modern fintech. Rexi automates reconciliation, accelerates financial close, and replaces fragile manual back-office workflows with intelligent agentic systems — building what Ignacio describes as the operating system for modern finance.

They discuss how the rapid proliferation of application-layer fintech providers has created a fragmented, modular financial stack in which money movement passes through multiple abstraction layers, making end-to-end transaction tracking increasingly difficult and resulting in systemic balance-sheet write-offs of one to two percent of total payment volume — a problem the Synapse collapse made viscerally real when over $160 million in user funds went unaccounted for overnight. Ignacio explains how Rexi approaches this as fundamentally a coordination problem: ingesting data files from disparate systems, parsing and standardising them with AI at speed, and deploying agents trained across the full portfolio of customer edge cases to investigate discrepancies and close out the long tail of exceptions that human teams routinely write off.

The conversation covers Rexi’s go-to-market approach — founder-led, in-person sales targeting operators rather than crowded enterprise conferences, with six-to-eight-week forward-deployed implementations designed to build trust inside critical financial infrastructure. With a seed round targeted for Q3 2026 and the team approaching 50k MRR, Ignacio explains why brand and relationships, not product features, will be the lasting competitive differentiator in an AI-commoditised market. He also shares hard-won leadership lessons drawn from Bain, Bitso, and Harvard Business School, and why no amount of prior experience truly prepares a founder for the consequential, real-time decisions of building a company from scratch.

This week on Tech Can’t Save Us, host Paul David is joined by Kim Smith, Founder and CEO of Health Evolve, a South Carolina-based femtech company building patient-centred technologies at the intersection of care and culture. Kim founded Health Evolve in 2023 following the loss of her daughter Lauren to HELLP Syndrome, naming the company’s flagship platform in her honour.

They discuss why the patient’s voice is the most underrated lever in closing health equity gaps, and how Health Evolve co-designed Lauren — with birthing women, nurses, and physicians across urban and rural communities — to be genuinely inclusive. Lauren supports women across a full 100 weeks of care, from preconception through early parenting, combining remote blood pressure and glucose monitoring, an AI-driven personalised education curriculum, and a telemedicine suite with real-time translation to fill the critical gaps between a high-risk woman’s average six hours of provider contact throughout pregnancy.

The conversation covers how Health Evolve is navigating long enterprise sales cycles by building a Research and Community Partnerships division as a deliberate profit centre, with an active clinical validation study at South Carolina’s largest academic hospital and a data partnership with the University of South Carolina drawing on 50 years of birth data. Kim also shares leadership lessons from 18 years spanning Tenet Healthcare’s 24 national markets, and her approach to protecting mental health whilst carrying a life-or-death mission — including her first-ever Power 24, a quarterly solo reset she’s making non-negotiable.

This week on Tech Can't Save Us, host Paul David is joined by Julio Martinez-Clark, co-founder and CEO of BioAccess, the world's first contract research organization (CRO) purpose-built specifically for first-in-human (FIH) clinical trials. They discuss the "valley of death" that claims roughly 90% of healthcare startups, which frequently fail not because their technology is flawed, but because they run out of capital before securing vital clinical data.

Julio explains how BioAccess helps medtech, biopharma, and radiopharma startups bypass these bottlenecks by compressing clinical timelines by 40% through efficient, predictable site selection and activation in regulatory-friendly Latin American markets. The conversation covers BioAccess's self-funded growth strategy, common pitfalls made by first-time founders, and how providing low-income patients with compassionate, advanced healthcare brings dignity back to clinical research. Julio also reflects on his time writing his book, La Cebolla de Pandora, and how that period of reflection shaped his deep commitment to prioritizing human impact over profit.

Healthcare startups face a high monthly burn rate averaging $300,000 to $400,000, making rapid first-in-human clinical data crucial to surviving the "valley of death" before they can raise more capital or secure an exit. Cost-efficiency in Latin American clinical settings does not mean lower standards, as all trials strictly adhere to the international ICH and GCP guidelines required by the FDA and EMA.

By leveraging an extensive network of hospitals and regulatory-friendly environments in countries like Panama and El Salvador, BioAccess achieves rapid site activation and patient recruitment.

Beyond the B2B framework, accelerating these trials democratizes access to life-saving medical innovations for lower-income patient populations who otherwise lack treatment options.

This week on Tech Can't Save Us, host Paul David is joined by Vojtech Oravec, the founder of Ranketta, an innovative platform helping companies measure and optimize their visibility within AI-driven search engines and answer engines like ChatGPT and Perplexity. With a deep background as an AI research scientist and enterprise product manager, Vojtech is now building the tools brands need to stay relevant in a rapidly evolving digital landscape.

They discuss the fundamental shift from traditional Google searches to AI-generated answers, exploring why direct answers are replacing the classic "10 blue links" and what this behavioral shift means for modern brands. Vojtech outlines the critical mistakes companies make when trying to establish AI visibility, such as completely blocking AI bots, relying on inaccurate API approximations, and focusing on brand visibility over more crucial product-level metrics.

The conversation dives deep into the world of Generative Engine Optimization (GEO) and how Ranketta bridges the visibility gap by scraping actual user interfaces to analyze citations, influential keywords, and product recommendation rates. Vojtech provides actionable insights for marketing teams, ranging from content enrichment with frequently asked questions to targeting specific AI-preferred keywords, while explaining how Ranketta integrates directly into existing workflows like Google Analytics and Shopify.

Vojtech also shares his strategic growth plans following Ranketta's recent €1 million pre-seed funding round, including scaling their dynamic team, achieving key revenue milestones, and establishing a crucial US beachhead to capture the fast-evolving AI shopping market. Finally, he reflects on his personal journey from navigating high-level AI research alongside famous scientists to becoming a tech founder at the cutting edge of the next generation of the internet.

This week on Tech Can’t Save Us, host Paul David is joined by Nick Lenten, founder and CEO at Ahead Health and a veteran of the tech world who previously served as head of product at Google. Ahead Health is on a mission to build Europe’s AI-driven prevention platform, offering advanced health checkups in under 60 minutes to bring elite-level preventative care to the general public.

The conversation explores the fundamental gaps in the European healthcare model, where a scarcity of expensive doctors and an aging population often force a focus on treating existing symptoms rather than long-term prevention. Nick explains how Ahead Health is tackling these challenges by democratizing the high-end “concierge” medical experience—typically reserved for the top 0.1%—through process optimization, AI, and extensive blood and imaging panels.

They dive into the strategic advantages of the Swiss market, noting its high talent density and a population already accustomed to paying out-of-pocket for healthcare, which allows for faster innovation. Nick also shares his approach to building a “customer-obsessed” health product that removes the friction and clinical clunkiness of traditional systems, aiming instead to create a “minimum lovable product” that acts as a personalized health companion.

Finally, Nick offers insights into the “super scary” emotional journey of a founder, the current VC climate for consumer health, and his “builder” leadership philosophy that prioritizes shipping real products over endless meetings. He envisions Ahead Health eventually becoming the center of gravity for a user’s preventative healthcare journey by connecting them seamlessly to the local medical ecosystem.

This week on Tech Can’t Save Us, host Paul David is joined by Ben Perreau, founder and CEO of Parafoil, a leadership intelligence platform that uses cognitive science and psycholinguistics to help managers evolve into exceptional leaders. They discuss the current crisis in management, where a “great flattening” of organizational structures has significantly increased the cognitive load on individuals who often wait an average of 10 years after their first promotion to receive any formal leadership training.

Ben explains how Parafoil addresses this gap by sitting unobtrusively in meetings to gather conversational data, providing managers with actionable feedback and behavioral insights based on their real-world interactions. The conversation covers Parafoil’s commitment to radical privacy and information security, ensuring that while the platform helps organizations track cultural change, individual transcripts and data remain private to the manager.

Ben also shares insights from the foundational work of James Pennebaker on psycholinguistics, revealing how the choice of “junk words” like pronouns and prepositions can uncover a leader’s cognitive state and team cohesion. Finally, they explore why “soft skills” are becoming the hardest constraint for performance in an AI-abundant world and how instrumentation for leadership is as essential today as a cockpit is for a pilot.

This week on Tech Can't Save Us, host Paul David is joined by Shawn Owen, CEO of SALT Lending, a pioneer in the blockchain space since 2016. As a serial entrepreneur with over 26 years of experience and a passion for Bitcoin dating back to 2011, Shawn provides a unique perspective on bridging the gap between legacy finance and the digital asset revolution.

They discuss the fundamental problems SALT aims to solve for long-term Bitcoin holders, specifically the ability to access liquidity and preserve wealth without being forced to sell their assets. Shawn explains how the company survived the "Wild West" of the crypto lending market by sticking to core principles and navigating complex regulatory shifts to become a regulated lender in 2026.

The conversation covers SALT's innovative product features, such as the Stabilization and Shield tools, which are designed to protect borrowers from the volatility of flash crashes by providing an "extension of time" rather than immediate liquidation. Shawn also sheds light on the company's strategic move to convert $64 million of debt into Series A shares, an alternative recapitalization structure that avoided the traditional bankruptcy process and strengthened the firm's position compared to fallen peers like FTX.

Looking toward the future, Shawn shares insights on the upcoming "Bitcoin Advantage" book and the potential for Bitcoin and real estate to merge as collateralized assets over the next decade. From his roots in the hospitality industry to building global fintech, Shawn reflects on the human element of technology, the importance of "obsessing over the customer," and why a transparent, decentralized financial system is essential for a better human experience.
