Founder-Led Capital
for Physical-World Technology
Three Nine Capital backs engineering-led ventures building useful products across safety, identity, connected devices, and real-world technology.
Built by Engineers.
Backing Builders.
Three Nine Capital was formed by engineers with roots at the University of Arkansas and a shared belief that durable companies are built by solving hard real-world problems.
The firm began by backing Augeas Technologies and continues to support selected ventures where engineering depth, founder conviction, and practical execution matter most.
We operate as a private, founder-led capital company — not a fund open to the public. Our backing is selective, deliberate, and built around long-term relationships with the builders we believe in.
“Durable companies are built by solving hard real-world problems.”
Before capital, there was engineering.
Three Nine Capital was shaped by hands-on engineering experience across electronics, embedded systems, industrial automation, plasma-based instrumentation, connected devices, product architecture, and real-world manufacturing. The firm's operating mindset comes from building systems where reliability, safety, and execution matter.
TipCharger Engineering Experience
Prior engineering work associated with TipCharger-style precision instrumentation and IonField Systems helped shape the team's understanding of high-voltage electronics, automation, laboratory workflows, reliability, and product execution in demanding environments.
We Back Builders of the Physical World
Embedded Systems
Firmware, real-time control loops, and silicon-close software for devices that operate in demanding physical environments.
Connected Devices
IoT architectures, wireless protocols, and cloud-device data pipelines built for reliability and scale.
Safety Technology
Systems where failure has real consequences — detection, alerting, and redundancy for life-safety applications.
NFC & Identity Infrastructure
Secure tagging, digital provenance, and identity systems for physical objects and assets.
Applied AI for Real-World Workflows
Machine learning and computer vision deployed on hardware where it changes operational outcomes.
Hardware/Software Products
Vertically integrated products that span physical manufacturing and software delivery — built to be owned end-to-end.
Industrial & Consumer Technology
Technology with durable utility for professional and consumer markets — built on engineering, not virality.
Portfolio Companies
Augeas Technologies
Augeas Technologies is a physical-world technology company developing practical consumer products across safety, identity, recovery, and connected-device workflows. The company builds software and hardware systems designed for real-world deployment — from smart home safety devices to NFC-based item identity infrastructure and voice-first family memory tools.
Stovyn
Kitchen Safety Technology
A kitchen and home safety platform combining passive sensor hardware with a connected app. Stovyn monitors cooking activity and detects unattended stove risks, providing real-time alerts and escalation contacts for everyday households, assisted living, and managed housing.
