Top Tech Startups in Austin, TX in 2026

Asgard Aerospace is building a coordinated industrial network that expands U.S. aerospace and defense manufacturing capacity. The company operates an advanced manufacturing and integration facility in Austin, Texas, and pairs this physical capability with Launchbelt, a secure digital platform that connects fragmented suppliers into a unified production ecosystem. Launchbelt provides a defense-aligned digital thread for travelers, traceability, QA, and compliance, with intelligent routing that evaluates capability, capacity, and performance across thousands of facilities. This creates predictable, high-reliability throughput for space, defense, aviation, UAS, and eVTOL programs. Asgard’s Command Forge facility serves as the anchor node of the network. It delivers composites, machining, harnessing, and integrated assembly with AS9100D and ITAR/CUI infrastructure, and it validates Launchbelt workflows through live production cycles. Each Forge is a replicable model that strengthens national aerospace capacity and supports program-level certainty for government and commercial partners. Asgard establishes a new category in the industrial base: a defense-aligned manufacturing network that synchronizes the operations of many facilities through a combined physical and digital platform. The result is faster onboarding, reduced coordination friction, higher quality, and an industrial system built for modern aerospace scale.

HealthKey helps clinics find eligible patients for clinical trials with AI. We partner with research organizations and community clinics, integrate with their operations, and use AI to surface patients who meet complex inclusion/exclusion criteria. We’re YC W25, seed-funded, in-person in Austin, TX, are growing fast, and have many paying customers and a backlog of signed clinics to onboard. And we need your help!

Torsei AI is building the next generation of autonomous ground systems for defense and dual-use applications. Our mission is to develop intelligent unmanned ground vehicles (UGVs) that enhance operational effectiveness, improve logistics, and reduce risk to personnel in complex and contested environments. We believe advances in artificial intelligence, autonomy, perception, and robotics are creating a new era of ground mobility similar to the transformation that unmanned aircraft have brought to the air domain. We are focused on building scalable autonomy software and mission-ready robotic platforms capable of operating in challenging real-world conditions. Our long-term vision is to create autonomous systems that support defense, security, industrial, and critical infrastructure applications worldwide. Torsei AI is currently assembling a world-class team of engineers, researchers, and advisors with expertise in robotics, AI, autonomy, and defense technology. We are looking for ambitious builders who want to work on hard technical problems and help define the future of autonomous ground systems. If you're passionate about robotics, AI, autonomy, and building technology that matters, we'd love to hear from you.
