Sergey Jakimov is the Managing Partner and co-founder of LongeVC, one of Europe's most active longevity-focused venture capital firms, currently raising its second fund targeting $250 million.

In this episode, Chris and Sergey explore the investment landscape shaping longevity biotechnology today. They discuss LongeVC's pragmatic approach to longevity investing—focusing on disease-modifying therapies rather than targeting aging itself—and why this strategy has been successful across their portfolio. Sergey shares insights from major successes including Rubedo's partnership with Beiersdorf and Turn Bio's deal with HanAll, explaining what these deals signal about pharma's evolving interest in longevity approaches. The conversation covers critical topics for researchers and entrepreneurs: common pitfalls in academic spin-offs, the importance of clear regulatory pathways, and how the upcoming patent cliff is creating new opportunities for early-stage biotechs in the longevity space.

Listeners will gain valuable insights into what makes a longevity company investable, how to navigate the transition from academic research to commercial venture, and why solving age-related diseases one by one may ultimately lead to a holistic understanding of aging itself.

The Finer Details:

• Sergey's journey from aspiring neurosurgeon to deep tech entrepreneur to longevity investor
• LongeVC's pragmatic philosophy: targeting specific diseases rather than aging as a whole
• The convergence of biotech, regenerative medicine, and AI in the longevity space
• Key criteria for early-stage investment: disease indication, balanced teams, clean IP transfer
• Why "five scientists in a room" and "great mouse data" don't make an investable company
• The importance of platforms having their own pipelines, not just service models
• How LongeVC's scientific advisory board (including Alex Zhavoronkov, Vadim Gladyshev, Thomas Rando) evaluates investments
• Success stories: Rubedo's senolytic partnership and Turn Bio's epigenetic reprogramming deal
• The changing dynamics between pharma and biotech driven by patent cliffs and urgency to find the "next GLP-1"
• Regulatory strategies: focusing on specific endpoints rather than aging broadly
• Making longevity medicine accessible through disease-focused approaches and data-driven validation
• Personal motivation: Sergey's experience as a rare disease patient and the urgency of advancing treatments

Quotes:

"Longevity as an industry is by far the industry with the biggest added value out there, because that is the issue that we all share. Without solving these things, none of the other stuff really matters—not FinTech, not blockchain, not sustainability."

"Five scientists in a room generally don't make a company. Prolonging rodent lives does not make a company either."

"The ultimate longevity drug version 1.0 would be a therapeutic which has an original disease indication, which also has somehow cracked the mechanism of action that would be translatable across several age-related disease domains."

"It is extremely arrogant for the space to say that we're not interested in age-related diseases, like we're not interested in curing the diseases. That's traditional biotech. We're not that. We are the longevity space."

"Pharma is still thinking in terms of assets rather than processes. It is almost impossible to sell a process to them... What pharma still wants is the result of that capacity actually coming to life."

"At the point when something has happened to you and a rare disease has happened to you... you're only equipped with that standard of treatment that is currently available and that has made it to the clinic."

"I think the presence of the FDA as this kind of gatekeeper-type agency saying, 'No, you cannot go after aging in a romanticized way. You actually need to focus yourself'—that benefits the field much more than it hurts the field."

In this special episode, host Chris Patil (VP-Media, BioAge) moderates a live panel discussion at the 25th Bay Area Aging Meeting at UCSF, bringing together six leading voices across the aging research ecosystem to tackle one of the field's most critical challenges: how to move promising discoveries from the laboratory to therapies that can benefit patients.

The distinguished panel spans academia, industry, and scientific publishing, featuring Janine Sengstack (CEO, Junevity), Saul Villeda (Professor, UCSF), Jodi Nunnari (Director, Bay Area Institute of Science, Altos Labs), Sebastien Thuault (Chief Editor, Nature Aging), Anne Brunet (Professor, Stanford), and Nir Barzilai (Professor, Albert Einstein College of Medicine). Together, they explore the most promising research directions for clinical impact, the revolutionary tools enabling modern aging research, and the structural challenges that must be overcome to bring longevity therapies to market.

Listeners will gain insights into the emerging science of cellular rejuvenation, the importance of systemic factors in aging, how to balance high-risk discovery with practical drug development, and the cultural shifts needed to better prepare the next generation of scientists for translational work. The panel also addresses the regulatory challenges of targeting aging itself as an indication and offers candid advice for young researchers navigating this rapidly evolving field.

• Cultural and structural barriers between academia and industry, including the shift from mechanism-focused to mission-driven research
• Balancing high-risk fundamental discovery with the practical needs of drug development and clinical translation
• The regulatory landscape for aging interventions and potential pathways to FDA approval beyond traditional disease indications
• Advice for young scientists: embracing rejection as part of the process, finding passion, working as teams, and considering diverse career paths in the growing longevity ecosystem

Quotes:

"Our goal as a company is to increase human health span, and the way I like to frame that more colloquially is we want to increase the number of happy, healthy years each person gets to spend on Earth." - Janine Sengstack

"There is an exquisite amount of plasticity left in an aging organism, both within the tissues, within the cells. There is plasticity that we can actually tap into." - Saul Villeda

"Burn bright, but don't burn out." - Jodi Nunnari

"The challenge that we run into is that there are so many combinations that very quickly it would become intractable to line up enough test tubes to test them all." - Sebastien Thuault, on the complexity of aging interventions

"We love our job. If not, we would not be doing it. I would do it again in a heartbeat... you get paid to play, to ask the questions that interest you, the approaches that interest you to play with who you want to—it is a fantastic job." - Saul Villeda

"Our life is a life of rejection...and still, we're having fun and making an advance. So don't give up." - Nir Barzilai

Michael Ringel is the Chief Operating Officer of Life Biosciences, a biotechnology company pioneering cellular rejuvenation therapies to reverse and prevent multiple diseases of aging. Michael became COO of Life just a few months ago, but he's been advising the company since 2018. Prior to this year, he was managing director and senior partner at Boston Consulting Group (BCG), where over a 25-year career he focused on R&D and innovation initiatives across the private sector and government.

Dr. Janine Sengstack is the Chief Scientific Officer and co-founder of Junevity, a company created in 2023 with the mission of extending health span and lifespan through what they term "Cell Reset therapeutics." The company recently secured $10 million in seed funding.

In this episode, Chris and Janine explore the innovative platform Janine developed during her PhD work in Hao Li's lab at UCSF, which now forms the foundation of Junevity's therapeutic approach. They discuss how the company uses computational and experimental methods to identify transcription factors that can "reset" cells from a diseased, aged state back to a healthy state while maintaining cell identity. Janine explains how Junevity is developing siRNA therapeutics targeting these transcription factors to treat age-related diseases, with a focus on metabolic conditions and other disorders that impact longevity.

The Finer Details:

• The development of the Reset platform during Janine's PhD work and its evolution into Junevity's therapeutic approach
• How transcription factors act as "managers" in cells, regulating many other genes
• Using AI and machine learning to identify the right transcription factors to target based on disease and tissue-specific data
• The validation process for siRNA therapeutic candidates in cell and animal models
• Junevity's focus on diseases with large-scale transcriptional dysregulation, including type 2 diabetes, obesity, muscle wasting diseases, and osteoarthritis
• The advantages of siRNA as a therapeutic modality for targeting traditionally "undruggable" transcription factors
• Junevity's business strategy and timeline, with clinical trials potentially beginning in 2026

Quotes:

"We tackled this high risk, high reward PhD project: we were inspired by the Yamanaka factors to say, 'Okay, let's find brand new transcription factors that we can target to take cells from a diseased, old state and bring them back to a healthy state while keeping them the same cell type, never turning them into a stem cell.'"

"Transcription factors: I like to think of them as managers in the cell."

"We think the advent of modern AI and machine learning tools to better analyze what they regulate, plus siRNA as a really well-proven therapeutic modality, really unlocks the ability to target transcription factors and really make powerful therapeutics with them."

"We're thinking about using transcriptional regulation as a way to come up with novel therapeutics to treat diseases that have a big impact on people's health span and lifespan."

"We want to advance our programs towards development candidates, which basically means the drug entity, and move them forward towards clinical development as fast as possible."

"I would love if we had multiple siRNA drugs on the market, ideally, or in late stages of development for a wide range of longevity-related diseases... We think that there's really huge potential here for making a big impact on a lot of different really complicated diseases."

Adam Freund (CEO) and Remi Laberge (CTO) are the founders of Arda Therapeutics, a biotechnology company developing novel therapies that selectively eliminate harmful cell populations driving chronic diseases. In this episode, they discuss their innovative approach to treating conditions like idiopathic pulmonary fibrosis by identifying and removing specific cell types that cause tissue damage, rather than trying to modify cellular behavior through traditional drug approaches.

The Finer Details:

• The concept of pathogenic cells as drivers of chronic disease
• How single-cell RNA sequencing enables precise identification of harmful cell populations
• Arda's approach to developing targeted antibody therapeutics
• Advantages of cell elimination versus pathway modification
• The potential for intermittent dosing to improve patient quality of life
• Future applications in aging and age-related diseases

Quotes: 

"Cells make up tissues. Tissues make up organisms... If you have the right cell at the right place, everything looks good. If you have the wrong cell at the wrong place, doing the wrong thing, the tissue will decay."

"We position our strategy as an alternative to traditional pathway targeting... changing cell behavior by blocking a single node could be quite challenging."

"This is game changer for the patient experience. If we're successful, our drug will be administered once a quarter, once every six months. But during that time, this patient feels like he is not a patient. He doesn't take a drug, he's not under treatment, and doesn't have the side effect of taking those drugs."

"We think that cell depletion is a broadly applicable strategy across many chronic diseases, including potentially aging itself one day."

"In 10 years from now... we will know precisely which cells to eliminate. Now, will we be allowed to do it in an otherwise healthy patient? That's a different type of question."

Quotes have been lightly edited for clarity.

"In the past, I've heard people refer to the DNA as the blueprint of biology, and I don't quite like that analogy. I think of it as more like the hardware, and the epigenome is the source code — the epigenome is responsible for the complex coordination of different genes that lead to proteins, and the temporal aspects of those so it's really how the hardware is used to make and maintain and change different cell types."

"We're opening up the epigenome as a platform for drug discovery. The vast majority of the genome is not the coding regions, but it's incredibly important in controlling gene expression. So there's a lot of biology in there to inform our selection of targets, and we think that could dramatically improve both the number of interesting targets and our ability to select targets. The data that we're creating, our expertise, and our computational tools make us amongst the best in the world at using the epigenome for drug discovery."

• The potential for immune secretome therapeutics to treat a wide range of age-related conditions and enhance healthspan
• The importance of developing affordable and accessible therapies to maximize impact

QUOTES

• "Every manifestation of aging is immunologically mediated. It's phenomenal. When one ages, your immune system in 100% of humans gets angry, so becomes highly pro-inflammatory."
• "Our drug is not a stem cell. It's not an immune cell. It is the secretion set, that same secretion set that you and I have, and everyone on this earth has, that precipitously declines with age, and now we're able to restore it."
• "We showed that IMMUNA fundamentally changes gene expression in order to promote the expression of genes for growth and regeneration. And then it inhibits the expression of genes that inhibit growth and regeneration."
• "I believe that this [secretome therapeutic] is going to be taken prophylactically by most humans, every quarter or so, to keep their immune system young, keep their immune system in a prophylactically competent state."
• "I want this thing to be available to everyone who wants it at an extremely low price, so that we can keep people alive, so that we can keep them disease free, so they can have productive years in their golden times, in their older age."
