Flux Secures $37M: AI Redefines Hardware Design
March 2, 2026, 9:33 pm
Flux, an AI hardware design innovator, raised $37 million in Series A and B funding rounds. The San Francisco company's platform automates Printed Circuit Board (PCB) development. It transforms text prompts into manufacturable electronic boards. This AI-powered solution simplifies complex hardware design, addressing component interoperability, cost optimization, and firmware generation. The capital will extend Flux's AI to advanced electronic use cases. Key investors included 8VC, Bain Capital Ventures, and Outsiders Fund. Flux aims to revolutionize hardware engineering, making custom electronics creation faster and more accessible for diverse industries.
Flux just made a big move. The San Francisco-based company secured $37 million. This capital arrived through a Series A and a Series B funding round. Flux, officially Defy Gravity Inc., pioneers AI-powered hardware design. Their platform promises a revolution for electronic engineering. It simplifies the complex world of Printed Circuit Boards (PCBs).
Hardware development has always been difficult. Traditional methods are slow. They demand specialized expertise. Design processes are often fragmented. Errors are costly. This creates significant barriers for innovation. Many projects face delays. Budgets often swell. Flux addresses these fundamental challenges. Their AI platform changes the paradigm.
Flux positions itself as the "AI hardware engineer." This is a new breed of AI agent. It handles hardware from conception to manufacturing. Users start with a text prompt. The system then designs a complete electronic board. This happens within a single browser tab. The process is end-to-end. It automates critical steps.
Printed Circuit Boards are vital. They form the backbone of all electronics. Every computer processor sits on a PCB. Sensors, accessories, and complex devices rely on them. Designing these boards is intricate. It involves precise component placement. Routing signal traces is complex. Multiple copper layers add to the difficulty. Flux streamlines this entire operation.
The Flux platform features an advanced eCAD environment. This is an electronic computer-aided design system. It integrates various workflows. Users benefit from reusable design blocks. Modern collaboration tools are built-in. This fosters efficiency. Teams can work together seamlessly. Design iterations accelerate.
Users interact with Flux through simple prompts. They describe desired PCB functionalities. A manufacturer might request specific sensors. A robotics firm could define autonomous vehicle computing needs. Flux interprets these requests. The AI then translates them into technical specifications. This removes much of the manual effort.
Flux’s AI intelligently determines PCB architecture. It assesses required layers. It recommends suitable components. The platform scans vast manufacturer databases. It identifies chips matching project criteria. This ensures optimal performance. It also considers market availability.
Component interoperability is a major hurdle. Not all parts work together. A theoretically suitable sensor might conflict with a processor. Flux automatically resolves these compatibility issues. This saves countless engineering hours. It prevents costly design errors. The system ensures a cohesive design.
Supply chain disruptions are common. Components go out of stock. Flux offers smart alternatives. If a part is unavailable, the AI suggests compatible replacements. It also focuses on cost optimization. The platform identifies opportunities for savings. It can recommend more affordable components. These alternatives maintain functionality.
Beyond design, Flux aids firmware development. Firmware is the software embedded in hardware. Creating it for new PCBs is challenging. Developers need deep hardware understanding. Flux simplifies this process. It distills complex PCB schematics. These become easily understandable. The platform also automates coding tasks. Firmware compatibility testing is one such automated function. This significantly reduces the learning curve.
The financial injection confirms investor confidence. Flux raised $10 million in its Series A. Outsiders Fund led this round. Bain Capital Ventures co-led. This initial capital fueled early development. The recent Series B round secured $27 million. 8VC led the Series B. Existing investors participated again. Bain Capital Ventures, Liquid 2 Ventures, and Outsiders Fund reaffirmed their commitment. This combined $37 million validates Flux's vision.
This fresh capital has a clear purpose. Flux will extend its AI capabilities. The goal is to tackle even more complex electronic use cases. The company plans to enhance its core AI engineering. More integrations with third-party PCB simulation tools are coming. Access to additional component databases will expand. This broadens the platform’s utility.
Flux aims to democratize hardware creation. It makes advanced electronic design accessible. Experts and non-experts alike can build custom solutions. This empowers niche audiences. It allows individuals to create unique devices. The impact extends across industries. Robotics, IoT, aerospace, and consumer electronics stand to benefit. Faster design cycles mean quicker market entry. Reduced costs foster greater experimentation.
The market for electronic design automation is evolving. AI integration is the future. Flux is at the forefront of this transformation. Their technology reshapes how hardware is conceived and built. It accelerates innovation across the technology landscape. This represents a significant leap for the industry. The future of hardware design is intelligent, automated, and accessible. Flux leads this charge.
