    What does it take to build companies across chemistry, software, diagnostics, and cell therapy, then bring those lessons into regenerative medicine? In this episode of Entrepreneur Rx, host John Shufeldt sits down with Robin Smith, CEO of Wonderlab Bio, a Jetstream Venture Fund portfolio company, to discuss his journey as a multi-exit entrepreneur, scientist, and biotech leader. Robin shares how he began as a chemist, how one unexpected customer order became his first bootstrap chemical business, and how that early work led to innovations in electronic lab notebooks, big data, and applied science. The conversation explores Robin’s path through Synthematix, ArtusLabs, and PerkinElmer, where he helped scale an informatics business and learned how to operate at a much larger level. Robin also reflects on the people, teams, and relationships that shaped his career, and why grit, optimism, and curiosity have been essential throughout his entrepreneurial journey.

    Visar Berisha: Proving What’s Real in the Age of Deepfakes

    How do you prove that the person speaking to you is actually human?  In this episode of Entrepreneur Rx, host John Shufeldt sits down with Visar Berisha, founder and CEO of OriginStory, to explore one of the most urgent problems emerging in the age of artificial intelligence: how to verify reality when voice, video, and identity can be convincingly replicated.  Visar shares how today’s AI tools can clone a person’s voice in seconds, why deepfakes are becoming a serious threat in financial transactions, hiring, healthcare, and everyday communication, and how OriginStory is working to create a new layer of “proof of personhood” for digital interactions. Rather than trying to detect fake content after the fact, OriginStory’s technology verifies human speech at the source by pairing audio with radar-detected biomechanical signals from the body.   The conversation also explores Visar’s journey from Kosovo to Arizona, his academic path through ASU and MIT, his earlier work using speech and AI to track neurological disease progression, and the lessons he learned building and exiting his first company.   From synthetic identities to AI-driven scams, enterprise security, entrepreneurship, and the future value of human connection, this episode looks at what it may take to build trust in a world where seeing and hearing are no longer enough.    About Visar Berisha: Visar Berisha is a Professor at Arizona State University, with a joint appointment in the College of Engineering and the College of Health Solutions; and founder and CEO of OriginStory. Berisha's main research interests reside at the intersection of AI and the human voice. He has developed and commercialized new speech AI models for healthcare and cybersecurity. This work is primarily funded by the National Institutes of Health, the Department of Defense, and the National Science Foundation. This work has led to many academic publications, several patents, and two VC-backed companies.  Berisha's work has been featured in the New York Times, on ESPN, National Public Radio, the Wall Street Journal, and a number of other international media outlets. He was the 2023-2024 ISCA Distinguished Lecturer.    About OriginStory: OriginStory is a proof-of-personhood company building the trust layer for human communication in the age of AI. OriginStory verifies that a real, live human is behind any conversation or recording. Its edge technology captures speech alongside human biosignals in real time, confirming the two align in a way only a genuine person can produce, and delivers continuous proof of personhood through a hardware-software platform. The approach is privacy-first (no biosignal data leaves the user's device) and validated to authenticate human-generated content, restoring trust in high-stakes moments like financial approvals, medical sessions, and executive communications where deepfakes and AI impersonation pose real risk.    About Xcellerant Ventures: Xcellerant Ventures is a venture capital firm that invests in innovative companies across healthcare, technology, defense, and other emerging industries.
