Episode 432: Johannes Galatsanos - CEO& Co-Founder, Diffraqtion

Episode 432 of The VentureFizz Podcast features Johannes Galatsanos, CEO & Co-Founder of Diffraqtion. I’m incredibly lucky to host this show because the guests I interview are truly out to rewrite the rules of what's possible. Johannes is a perfect example. He brings over 15 years of deep expertise across AI, quantum tech, and operations across a career that includes lots of deep research in academia to executing massive, corporate AI initiatives at global giants like Novartis. So, what does someone with that background do to push the absolute limits of technology? How about building a space company that is creating the world’s first quantum camera to help satellites and machines see further and think faster? By blending quantum photonics with cutting-edge AI edge-computing, Diffraqtion’s technology enables satellites and telescopes to bypass traditional lens constraints entirely—delivering 20 times higher resolution and 1,000 times faster processing speed, all at a fraction of the cost. As you’ll hear from this interview, there are a countless number of use cases and industries that are perfect for Diffraqtion’s technology, which puts them in an ideal spot to build a massive anchor tech company in the Boston startup scene.

Episode 431 of The VentureFizz Podcast features Cathy Lewenberg, CEO of Bevi. When most people think of a beverage company, they immediately think of a traditional consumer brand fighting for shelf space at the grocery store.

Episode 430: Phil Beauregard - Managing Partner, Impellent Ventures

Episode 430 of The VentureFizz Podcast features Phil Beauregard, Managing Partner of Impellent Ventures. I first met Phil back when Boston was going through another massive resurgence of growth following the financial crisis of 2008. It was a special time when local founders and investors banded together to help build and scale the Boston tech ecosystem. It was a movement that is reminiscent of what we are seeing today with the Mass AI Coalition. There was a major buzz in the air back then, and it worked, resulting in the launch of multiple successful companies, including two of Phil's own startups which were both acquired. There is a phrase that Phil commonly uses, which is “why join the Navy when you can be a pirate” and I think it speaks volumes to his mentality and how they deploy capital at Impellent Ventures. They don’t just simply follow the herd, especially when it comes to finding elite entrepreneurs. They are entirely location-agnostic and welcome working with exceptional founders who are tackling massive, real-world problems in emerging ecosystems... not just out in Silicon Valley. Impellent Ventures is focused on making seed and pre-seed investments. The firm is led by Phil, David Brown (who previously appeared on Episode 190), and Tariq Trotter, aka Black Thought of The Roots, who serves as a General Partner at the firm. In this episode of our podcast, we cover: * A conversation around building startups outside of San Francisco, and why we are living through the "consumerization of the enterprise" era. * The correlation between smaller fund sizes and investor returns. * Phil’s background growing up in New Bedford and studying business at The Wharton School at UPenn, plus how he first caught the entrepreneurial bug and met his co-founder, Matt Grace. * The inside story behind his two exits: Objective Logistics to Carbon Black and Rekindle to HubSpot. * His transition from operator to investor at Impellent Ventures, plus all the details on their unique investment criteria, portfolio company examples, and how Tariq Trotter joined the firm. * His role as an early advisor to multiple successful tech companies, including the critical advice that Toast luckily chose not to take. * How Phil is leveraging AI to build his own Relationship Intelligence System, helping him scale his ability to "pay it forward" to the ecosystem. * Plus, so much more!

Episode 428: Mike Pappas - CEO & Co-Founder, Modulate

Episode 428 of The VentureFizz #podcast features Mike Pappas, CEO & Co-Founder of Modulate. Is Boston the best place to build a voice AI company? Based on its rich history in this category, I would have to say 1000%. From the early days of ScanSoft and Dragon to SpeechWorks and Vlingo—all of which eventually fell under the voice juggernaut Nuance, which worked on the early days of Siri and was acquired by Microsoft—the pedigree in this city is unmatched. Add in players like Bose, Vivox, and the sizable presence of Amazon Alexa in the area, and it's clear: Boston is the voice capital of the world. Mike Pappas and his co-founder Carter Huffman are adding a massive new chapter to that legacy and thatis Modulate, a venture-backed voice intelligence company building AI models and APIs designed to understand real-world conversational audio at scale. Modulate is the company behind ToxMod, the world's most advanced proactive voice moderation platform. If you’ve played Call of Duty lately, you’ve likely interacted with their tech. And, the company recently launched a new product called Velma, the leading AI-platform for real-world voice intelligence. In this episode of our podcast, we cover: Mike’s perspective on the shift from license-based to usage-based pricing models. Mike’s background story—from his physics studies at MIT to his early career at Bridgewater Associates. Entering "startup land" at Lola and the critical hiring lessons he learned while working alongside Paul English. The founding of Modulate and the pivotal moment when they realized the tech they built was actually the solution to a massive safety problem in gaming which led to a relationship with Activision. All the details about ToxMod and Velma, including customer examples and use cases. Why their dataset is a "moat" that makes their technology uniquely defensible in the age of generic LLMs. Mike's advice for first-time founders on raising capital and building a high-performance culture.
