Matt Brown, better known as SuperfastMatt, joins Jim Belosic to talk about his unconventional path from delivering pizzas to becoming a mechanical engineer, working at Nascar, Tesla and Apple, to eventually building one of YouTube's favorite automotive channels.

Along the way, Matt shares stories from NASCAR, Formula SAE, Tesla, and some of the wild projects that have made his channel so popular. They get into engineering, fabrication, YouTube, creative problem solving, and why building real things teaches lessons you can't learn in a classroom. From his off road Dodge Viper to land speed racing and dreams of building an airplane, Matt explains how following whatever seems interesting has led to some pretty incredible opportunities and a lot of entertaining projects.

In this episode of Just Gonna Send It, Jim Belosic sits down with Barrett Ames, robotics engineer, startup founder, former NASA researcher, and CTO of REK, a humanoid robot fighting league inspired by Real Steel. Barrett shares his journey from building robots as a kid to working on NASA’s Valkyrie and Robonaut 2 projects, earning a PhD in AI and robotics at Duke, and launching startups focused on construction automation and entertainment robotics.

The conversation explores the realities of building hard tech, lessons learned from failed startups, the future of humanoid robots, and why competition and destruction might actually accelerate innovation. From DARPA challenges and space robotics to robot MMA fights in San Francisco, this episode is packed with stories about curiosity, risk taking, and learning through building.

Divya Thakur, founder of Yardbot, joins host Jim Belosic to discuss how he’s building a next-gen landscaping company powered by robotics. Instead of chasing full automation, Yardbot combines human crews with custom-built mowing robots to deliver better results at a lower cost.

Divya shares his journey from software engineering and finance to self-driving cars at Cruise, and how a failed Bitcoin startup taught him one of his biggest lessons: build for customers, not just cool tech. We get into the gritty reality of developing hardware, five generations of robot iterations, and what it takes to run a tech-driven business in a traditional industry.

Sam Holland, co-founder of Informal, joins Jim to talk about how a hands-on approach to building led him from early 3D printing and MakerBot to helping companies bring real products to life. What started as curiosity turned into a career built on experimenting and learning directly from the manufacturing process.

They get into the messy reality of hardware, from the gap between prototype and production to the importance of communication, proximity, and experience when working with suppliers. Sam breaks down why most projects fail in execution, not ideas, and how Informal helps teams move faster by connecting them with the right people at the right time.

Sam talks about what it takes to get started today and why building real things early matters more than credentials, and how accessible tools have changed the landscape for hardware founders. 

Zane Hengsperger, founder and CEO of Nox Metals is focused on fixing one of manufacturing’s most overlooked bottlenecks; getting raw material fast, reliably, and without friction. 

In this episode of Just Gonna Send It, Jim and Zane walk through his path from growing up around a machine shop to a brief run in tech, and ultimately back into manufacturing to build something of his own. They get into why software alone is not enough, how applying technology to simple processes creates real leverage, and what it actually takes to stand up a physical operation from scratch. From buying and rigging a massive saw to running the shop themselves after hours, it is a conversation about moving fast, learning by doing, and building where it matters.

You may know Emanual Moshouris from his recent CNC machining challenge for SendCutSend or his reputation of being the “that could have been sheet metal” guy on X. Known to many as his X handle “Emm0sh”, in this episode of Just Gonna Send It, Jim and Em talk about his unusual engineering career path that took him from designing custom rigging for Taylor Swift concerts to Macy’s Thanksgiving Parade to Amazon robotics and Apple’s iPhone team. Em reflects on mentorship, humility and why real competence matters more than titles. He also brings a variety of questions to the table for Jim about growing companies, meaningful industrial innovation and why the future of manufacturing depends on leapfrogging old systems rather than rebuilding them. 

Jim sits down with Ryan Callahan, the engineer behind KegRocket, to talk about how a side project turned into one of the most fun and approachable takes on amateur rocketry. Ryan walks through his journey from flying Estes rockets as a kid to building liquid rockets in college, working at Blue Origin, and eventually deciding to build a real liquid fueled rocket out of beer kegs in his spare time. They get into why hands-on experience beats perfect resumes, how tight budgets and weird constraints actually spark better ideas, and what it really takes to design, test, and launch a liquid rocket outside of a massive aerospace program. It’s a conversation about learning by doing, balancing a demanding day job with ambitious side projects, and why chasing what genuinely excites you often leads to the best results.

Solange Massa’s career has spanned worlds that rarely overlap. In this episode, Jim sits down with the Ecoatoms founder to trace her journey from professional opera singer to medical researcher and ultimately to building space-ready payloads for microgravity experiments. Solange explains how curiosity, resilience, and learning through failure shaped her path, what it really takes to send experiments to space, and why some of the most meaningful breakthroughs happen when you stop following the expected route.

Garrett McCurrach and Canon Reeves of Pipedream Labs join Jim to share how they are rethinking logistics by building underground delivery networks for automated cities. From scrappy early experiments to becoming their own first customer, they explain why real infrastructure requires long term thinking, hands on execution, and a focus on purpose over hype.

Cameron Schiller, Founder and CEO of Rangeview, joins Jim to share how Legos, robots and competitive VEX battles led him to build one of America’s most ambitious modern foundries. From a formative stint inside Chinese factories to creating automated casting systems for mission-critical defense and energy parts, Cameron explains why the future of manufacturing depends on curiosity, conviction, and bringing capability back home.
