Leslie Loveless leaves the classroom for pharmaceutical sales in 1999, a coveted industry at the time. She describes the culture shock of moving from a school building into a territory-based role, where her days meant driving between providers, managing her own schedule, and learning to sell one to one.

Leslie Loveless starts at the beginning: growing up in a close-knit Indiana family, watching her father build a career as a pharmacist, and learning early that education mattered even if the eventual career path was left up to her.

He then turns to company building at Axelyf: in vivo cell reprogramming for solid tumors, modular lipid nanoparticles, AI-informed discovery, external partners, and a deliberately lean operating model. The conversation closes with the mentors, expectations, and leadership philosophy shaping his next chapter.

The conversation covers layoffs, company transformation, patent cliffs, biotech's feast-and-famine cycles, modified mRNA, and the effort required to scale production from tiny academic batches to grams and kilograms.

At Merck, a three-month visa detour exposed Örn to another laboratory and reinforced the value of adaptability. He then describes leaving a secure role for Transform Pharmaceuticals, building a small team and collaborative culture, developing new formulation technologies, and helping create the patents and assets that led to a Johnson & Johnson acquisition.

He describes his first research opportunity at the University of Iceland, an early industry project in Copenhagen, and the mentors who pushed him toward bioorganic chemistry. The conversation follows his move to UC Santa Barbara, his work with Tom Bruice and Alex Klibanov, and the networking connection that led to Merck.

Philip breaks down the hidden costs of traditional lab leases, from equipment maintenance and utilities to medical waste, freezer alarms, and unused square footage. He explains how flexible space can help emerging companies stay focused on milestones while preserving critical capital.

Philip Borden describes leaving Frazier Healthcare Partners for Harvard Business School, where the case method broadened his perspective beyond healthcare and investing. He explains why he returned to healthcare investing after graduation.

Philip Borden explains how realizing he did not want to pursue a PhD or spend his career at the lab bench led him toward venture capital. With a molecular biology degree, limited finance experience, and a list of biotech VC firms, he picked up the phone and cold-called his way into Frazier Healthcare in Seattle.

Philip Borden grew up in Plymouth, Indiana, in a family shaped by agriculture. He talks about his grandparents' farms, his father's work as an agricultural lender, and the early lessons he absorbed about local businesses and long-term relationships.

In this part of the podcast, Nathan Clark explains how Ganymede approaches data integration and automation in life sciences. He discusses why lab instruments and workflows require customized connectors, how a developer platform can help teams adapt integrations quickly, and why moving data online is only part of the challenge.

Nathan Clark walks through his work at Benchling, where he managed the Insights business intelligence product and helped develop an early machine learning effort. He explains why operational wet-lab data is fundamentally different from omics data, and why the relationships between samples, programs, instruments, locations, and people matter as much as the experimental results.

The conversation then turns to product management. Nathan describes the discipline as understanding why a product should exist, grounding decisions in user needs, and translating research into what a team builds. His advice for early-stage founders is direct: stop coding until they've done enough customer research to understand the problem.

Nathan Clark reflects on the formative influence of his entrepreneurial father, who showed him that business and even home building are learned through research, effort, and execution rather than secret insight. Nathan also discusses his unconventional high school experience, his decision to study business and finance at the University of North Carolina, and the early interest in biology and futurism that stayed with him.

David Li explains how a research question about mischaracterized drug targets became the starting point for Meliora Therapeutics. He describes how CRISPR experiments and follow-up biology challenged the accepted mechanism for cancer drugs, and how the company uses AI and machine learning to connect chemistry, biology, biomarkers, and patient populations.

In this part of the podcast, David Li, CEO and co-founder of Meliora Therapeutics, reflects on his experience helping build Everest Detection around the challenge of finding lung cancer earlier. He discusses the potential of a noninvasive, blood-based test, why lung cancer can be difficult to detect in blood, and how access to early-stage clinical samples helped the team investigate the problem.

In this part of the podcast, David Li reflects on leaving finance after realizing that an investing career would not give him the tangible impact he wanted. He explains what KKR taught him about business and patient needs, then describes the team-and-market test that led him to Benchling.

In this part of the podcast, David shares how the Roy Vagelos Life Sciences and Management dual degree program at the University of Pennsylvania opened his eyes to the possibilities of combining scientific discovery with business acumen. A pivotal summer internship with Arie Belldegrun at UCLA—during which Kite Pharma was born—planted the seed for his future in life sciences entrepreneurship. He also discusses his transition into finance, landing at Goldman Sachs, and the lessons learned from sitting in boardrooms alongside C-level executives at critical moments in companies' life cycles.

In this final episode of The Biotech Startups Podcast series, Jon Chee sits down with Mati Gill, CEO of AION Labs, to unpack where AI value is actually being created in biopharma—and what comes next. Mati lays out three pillars driving a post-hype phase of sustainable growth, explains why the industry is structurally conservative for good reasons, and shares how AION Labs is already preparing for the quantum computing wave before it arrives.

Jon Chee sits down with Mati Gill, CEO of AION Labs — an Israeli venture studio backed by AstraZeneca, Merck, Pfizer, Teva, AWS, and the Israel Biotech Fund. Mati breaks down how AION Labs builds AI-native pharma companies from the ground up: industry-grade problem statements, multidisciplinary teams, and pharma partner POC commitments locked in before a startup is formed.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Mati Gill, CEO of AION Labs. Mati traces his path from juggling a minister's bureau with Israeli law school to joining Teva as an intern with no private-sector experience, then learning a 45,000-person org from the chart up — until Teva's financial crisis handed him the mandate to build the innovation program that became AION Labs.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Mati Gill, CEO of AION Labs—a first-of-its-kind AI venture studio backed by Teva, Pfizer, AstraZeneca, Merck, and Amazon Web Services. Before AION Labs, Mati spent six years in the IDF, ran a minister's bureau, and rose from legal intern to global legal COO at Teva over more than a decade. Part one covers the formative years: moving from Columbus, Ohio to Jerusalem at 12, extending military service by three years, and the two teachers who handed him D's and changed how he works.

In part four, Alex Telford, founder of Convoke, covers the platform architecture and roadmap. He walks through Convoke's modular system—building validated structured datasets from trial registries, regulatory filings, and patents, then stitching them with workflow tools for competitive intelligence and document generation. He breaks down how pharma and biotech customers engage differently, why an "everything app" is a trap, and how Convoke is moving from reactive data storage toward proactive, predictive intelligence.

In this episode, Jon Chee sits down with Alex Telford, founder of Convoke, to examine why large pharma resists AI transformation. Drawing on seven years at Charles River Associates, Alex maps the coordination tax of siloed orgs, the tacit knowledge lost when experts retire, and why software efficiency is the wrong axis to compete on. His frame: factory electrification — the gains don't arrive until you redesign the whole org around the technology.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Alex Telford, founder of Convoke, who spent nearly seven years in biopharma strategy consulting before what he calls "AI psychosis" set him on a different path. Alex traces the arc from biochemistry at Bristol and synthetic biology at UCL to discovering consulting existed only after graduating, joining a boutique Swiss firm two weeks before it was acquired, and learning one core lesson: clients want a recommendation to push back on, not a data dump.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Alex Telford, founder of Convoke, who raised $8.6 million to build the AI-native operating system for biopharma.

From re-engaging demoralized scientists after layoffs to a Moderna encounter when the company was just eight people strong, Martin offers a rare insider view of what it actually takes to drive innovation from within Big Pharma.

Jon Chee sits down with Martin Brenner, CEO and CSO of iBio, an AI drug discovery company building immunotherapies for difficult-to-treat cancers. Before biotech leadership, Martin built one of pharma's most unconventional careers—electrical engineer in Stuttgart, vet medicine at LMU Munich, PhD embedded at Eli Lilly, youngest scientist to lead a 20-person team there. Part 1 covers his formative years: the family that shaped him, the vet clinic that changed his path, and the professor who lit the match.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Mike Stadnisky, Managing Director of Thielsen Capital, a seed-stage life science tools syndicate. A veteran of four-plus M&A cycles as CEO of FlowJo and Phytonix, Mike walks through the mechanics founders most often get wrong: when to call in partnership favors, how shared customers become acquisition seeds, what IP and cap table hygiene should look like before a deal, and why a rigorous financial model is your most powerful negotiating tool.

In this episode, Jon Chee continues his conversation with Mike Stadnisky, Managing Director of Thielsen Capital, on his transition from academic scientist to BD leader. Mike unpacks what business development really means in life science, why chasing "the decision maker" is the wrong frame, and how to identify the technical and business champions who actually move deals inside large organizations.

In this episode of The Biotech Startups Podcast, Jon Chee sits down with Mike Stadnisky, Managing Director of Thielsen Capital — a seed-stage life science tools syndicate. Before Thielsen, Mike was CEO of Phytonix (acquired by Thermo Fisher) and FlowJo (acquired by BD Life Sciences), and has taught at MIT Sloan. In Part 1, Mike traces his path from growing up with a chemical engineer father who gave him early exposure to business strategy, to studying biochemistry at Clemson, to working as a Red Bull Student Brand Manager — a role that shaped his enduring "care before you share" philosophy: meeting people where they are, not where it's convenient. He carried that mindset into grad school at UVA, where he joined Michael Brown's lab to study NK cells and innate immunity, fell in love with flow cytometry, and had his first (tearful) encounter with FlowJo.

In this episode of The Biotech Startups Podcast, we dive into how Nalu Bio CEO and co-founder Caitlyn Krebs is harnessing AI and the largely untapped endocannabinoid system (ECS) to build the first nonhormonal therapeutic for the two hundred million women living with endometriosis, while running an ultra-lean company with no lab, no university royalties, and a fully outsourced CRO/CMO model. She explains why CB1 and CB2 GPCRs are among pharma’s most druggable targets, how Nalu’s platform has sped drug development by 5x while doubling phase one success rates, and why the ECS may be medicine’s most overlooked frontier amid a women’s health landscape still dominated by opioids, chemical menopause, and invasive surgery.

In this episode of The Biotech Startups Podcast, Caitlyn Krebs traces her path from a gut-punch company shutdown on maternity leave — which unexpectedly forged a key cofounder relationship — through the digital health boom at Rock Health, to her role as COO at Neurotrack, where an eye-tracking Alzheimer's test launched to 137 countries within days and led to selling cognitive risk scores to Japanese life insurers as the only woman in the room. She closes out her pre-Nalu journey at BlueStar Genomics, where hard lessons in capital discipline and the dangers of scope creep shaped the focused, founder-ready mindset she brings to building Nalu Bio today.

In this episode of The Biotech Startups Podcast, Caitlyn Krebs, co-founder and CEO of Nalu Bio, traces her path from building the Bay Area's biotech ecosystem to operating at the cutting edge of science and business. She shares how launching BayBioNEST taught her what it really takes—beyond great science—to build durable companies, before diving into her time at Entelos, where she helped pioneer virtual patients and digital twins nearly twenty years before AI became a buzzword, and unpacks what BD actually means in biotech, from navigating black-box skepticism to running "bake-off" pilots that let the data speak for itself. The conversation then shifts to Tethys Bioscience, where Caitlyn helped bring a prediabetes diagnostic to market—winning over physicians, employers, and major payers like Aetna, United, and Cigna—only to watch a single Medicare/CMS misstep shutter a well-funded company, and what every founder can learn from that hard-won experience.

In this episode of The Biotech Startups Podcast, Caitlyn Krebs, co-founder and CEO of Nalu Bio, traces her journey from tagging endangered sea turtles on the Big Island of Hawaii to leading an AI-powered company designing novel cannabinoid-inspired small molecules for pain, inflammation, endometriosis, and metabolic disease. She reflects on being humbled at Brown University, where she fell in love with data analysis while studying leptin and early obesity science, then recounts jumping into the Bay Area’s dot-com boom as the third employee at a startup before, at just 27, taking the helm of BayBio and managing a 26-person board of biotech leaders—along the way crossing paths with a 20-year-old Stanford dropout named Elizabeth Holmes.
