AI in practice: 2 real uses of AI described

What this episode covers

Sean Petterson, CEO of Supersede, explains how his company turns recycled plastic into structural building materials like Marine Board and OSB alternatives, starting with boats and expanding to RVs. He details a capital-efficient manufacturing model using small, distributed plants in Phoenix and Bristol, Indiana, to serve local markets and reduce logistics costs. Petterson highlights the use of AI for tool design, machine vision for quality control, and a custom-built ERP system developed without software developers to streamline operations. The company aims to build 10 plants in five years, leveraging first principles and domestic manufacturing trends to compete with traditional lumber products.

Engineering & simulationSlack, Jira, GitHubbuilt ERP without software developers

The team used AI coding tools to build an internal ERP system without software developers, dispersing product management needs into Slack channels that fed into Jira and GitHub, allowing the production team to iteratively design the software they needed.

“we're doing by just dispersing the needs into effectively things like Slack channels, where we can backchannel things into into Slack, have that go up into Jiro, have that fall down into a GitHub repo, and have this iterative cycle where the team is truly designing the N ERP that is required for them.”

Sourcing & supply chainscrapersinformed product development based on pricing data

The company built software scrapers to monitor current pricing for lumber and other building materials, using this data to inform product development decisions such as adding features or dialing back costs based on market fluctuations.

“we build scrapers that understand what current pricing is. And so, Lumber, particularly, but most commodities that are in the building materials market fluctuates so heavily, particularly right now, just the state of global economic affairs, and, That, allowing us to inform that in our development process, is just saying, hey, maybe we can add this extra feature to this, or maybe we need to dial back this feature.”

    Meet The HIBT Fellows: Dinesh Tadepalli & Jennifer Zeitler

    Dinesh Tadepalli, co-founder of Incredible Eats, explains how he leveraged his semiconductor engineering background to automate the manufacturing of edible cutlery, using compression molding and trade-secret molds to solve the plastic pollution problem. Jennifer Zeitler, founder of Let's Goat Buffalo, describes her land management service that uses rescued goats and converted school buses to clear invasive plants without heavy machinery or chemicals. Both founders discuss their bootstrap financing strategies, including Tadepalli selling his home to fund machinery and Zeitler pricing her services competitively against traditional landscaping. They detail their pivot to retail and B2C channels during the pandemic, securing orders from major retailers and concert venues while navigating supply chain and operational challenges.

    Back to the Future: The Manufacturing Edition

    Marty Groover, Partner and CTO at C5 MI, draws on his 21-year career as a US Navy Surface Warfare Officer and his time at Caterpillar to explain how live data and modular systems drive manufacturing efficiency. He argues that manufacturers must converge people, process, and technology rather than leading with technology, citing Rivian’s modular skateboard platform and Amazon’s logistics as examples of future-proofing. Groover warns against 'best and breed' IT strategies, advocating instead for a common operational picture and distributed manufacturing to overcome supply chain fragility and inflation.

    005: Miniature Construction Materials

    Mat Hofma and Erik Polumbo, founders of Mini Materials, explain how they launched a business selling miniature cinder blocks and pallets using a budget of under $500 for prototyping. They detail their process of 3D printing, creating silicone molds, and casting real concrete, while leveraging Instagram and Reddit for organic marketing. The duo discusses their decision to keep manufacturing in the U.S. to maintain margins and quality, and their strategy for scaling production by contracting local individuals rather than using large overseas factories.

    EMS@C-LEVEL Season #2021 Episode #7 with Mariana Kobal and Shane Hassett, WAZP

    Mariana Kobal and Shane Hassett, co-founders of WAZP, explain their asset-light, distributed manufacturing model that uses 3D printing to produce volume goods closer to the point of need. They discuss overcoming early skepticism from the eyewear industry regarding quality and price, and detail a large-scale project with IKEA where they produced products for 50% of their global stores using 100% waste materials. The founders highlight how the pandemic accelerated the shift to direct-to-consumer (D2C) fulfillment and near-shore manufacturing, aiming to deploy automated 'print-and-fulfill' factories in locations like post offices.

    Alex Blum: $1200 Houses, Plant-based Plastics, Political Activism, and BioFi | Hard Tech Podcast #11

    Alex Blum, co-founder and CEO of Applied Bioplastics, discusses his company's plant-based biocomposites, specifically the refugee shelter material Betterboard and the injection-moldable thermoplastic BioFi. He explains how Applied Bioplastics avoids the common failure mode of bioplastics startups by licensing their cellulose-compatibilizing technology to existing compounders rather than building factories, ensuring commodity pricing and compatibility with standard industry equipment. Blum also details the company's low-tech, hand-layup manufacturing process for shelters that empowers local communities in disaster zones, and shares his personal philosophy on employee retention and his response to a severe health diagnosis.
