In this episode we welcome Ann DeWitt, General Partner at Engine Ventures. She introduces Engine Ventures and how it grew out of MIT to back tough tech companies that work across disciplines, beyond the biology and computer science startups that usually draw investors. Ann also explains the programs and resources offered by Engine Ventures to help founders transform their ideas into successful businesses. With her VC perspective, Ann covers the importance of clear checkpoints and staged funding for companies with long timelines and heavy capital needs. She discusses why impact has to come first if a financial return is going to follow, offering plenty of advice for founders and early career scientists. Ann shares what it takes to catch an investor's eye when they are deciding which startups to back.   Time Stamps0:55 Introduction to Ann Dewitt and her transition from scientific research to venture capital 6:38 Introduction to Engine Ventures 10:00 What is tough tech and what makes it different from other startups 16:13 Why investor prioritize “impact”24:06 Future growth opportunities within the neurology field 28:47 Common challenges founders face and how to overcome them33:22 Advice for scientists on building a business perspective 38:46 Women in biotech 45:52 Quick fire questions

The Nucleate Podcast welcomes Matias Serebrinsky, co-founder of Psymed Ventures. Raised in Argentina by a physician father and an economist mother, he shares how his early life influenced his comfort with risk and his drive to do work that helps others. Matias shares his path from Sony marketing to starting CookUnity, and eventually to building a venture fund focused on brain and mental health. The conversation provides a look into the latest trends in neurotech and brain health investing, from psychedelic therapeutics to precision psychiatry and RNA therapies. Matias offers plenty of advice for entrepreneurs on pitching their startup ideas and how to pair technical knowledge with business acumen.

In this episode of the Nucleate Podcast, Dr. Jo Viney, co-founder, president, and CEO of Seismic Therapeutic, shares her trajectory from academic immunology training in London to major biotech companies and startup leadership. She discusses how early clinical lab exposure to autoimmune patients sparked her passion for translational science and highlights why the Boston ecosystem is an ideal place to launch biotech startups due to its unparalleled funding, incubator space, and collaborative peer networks. She also reflects on the lessons learned from co-funding Pandion Therapeutics—including how following surprising data led to a major asset acquisition by Merck—and describes the bittersweet feeling of handing off a company she helped build. The conversation then explores Seismic Therapeutic's approach to tackling autoimmune diseases by integrating machine learning into protein drug discovery. Jo details how combining structural biology, machine learning, protein engineering, and immunology allows Seismic to accelerate drug design cycles, optimize enzyme therapeutics, and tackle complex agonist and cell-selective antibody design. She emphasizes that machine learning serves as a powerful tool guided by human hypothesis-driven research rather than a standalone cure-all. Jo closes with practical advice for emerging scientific founders, encouraging them to seek out diverse viewpoints, pressure-test their ideas with critics, and keep patient impact as their true North Star.
