Summary
Written by a model from the transcript; not yet reviewed.
This episode covers two distinct frontier startups reshaping their respective industries through novel engineering approaches. In the first segment, Zach Hudson, CEO of Onton, demonstrates how a neurosymbolic AI search engine outperforms traditional LLMs by reasoning through aesthetic taste, multi-category e-commerce queries, and real-time learning without expensive retraining. Later in the episode, Ashi Disanayaka, co-founder and CEO of Spacium, explains how her team built zero-boil-off cryogenic fuel tanks and ultra-precise robotic actuators in-house to solve the critical bottleneck of in-space satellite refueling. Both founders discuss the mechanics of building lean, obsessed teams that iterate rapidly on complex physical and computational hardware.
- Deploy neurosymbolic AI models for e-commerce or complex search to enable real-time learning and transparent, trustworthy logic without massive frontier model training costs. 0:00
- Build in-house testing facilities and keep your core engineering team lean to drastically accelerate hardware iteration cycles in deep tech. 39:17
- Focus on zero-boil-off cryogenic storage technology to make in-space refueling economically viable for long-range missions like lunar travel. 32:22

About this episode
This Week In Startups is made possible by: Vanta https://www.vanta.com/twist Agree https://agree.com YSecurity https://YSecurity.io/TWIST Today's show: Frontier AI models can ace PhD-level exams, but it's still bad at tracking down the product you want in the style that suits you. Onton's Zach Hudson tell us that the problem is that models are a black box. His solution? A neurosymbolic model, Ontology 1, that learns about your taste and preferred aesthetic over time, then produces product searches tailored specifically to you, rather than just using keywords and relevant tags. How do neurosymbolic models work, and how does Onton understand your prompts and favorite design trends? And why aren't the frontier labs working on neurosymbolic models of their own? Zach joins Jason and Lon to discuss. PLUS, following a record-smashing SpaceX IPO, Ashi Dissanayake of Spacium makes the case that the real bottleneck in space isn't launching rockets off the ground any more. It's refueling in orbit.
