Company profile
researched Aug 2026Flux develops a browser-native electronic CAD (eCAD) platform for printed circuit board design in which AI assists across the design workflow. Users describe a target device — for example a temperature and humidity sensor node, a stereo Class-D portable speaker, a field-oriented-control brushless DC motor driver board, a 1S Li-ion power module with charger, protection and fuel gauge, or a dimmable constant-current LED buck driver — together with connectivity (Wi-Fi, Bluetooth Low Energy, USB-C data, USB-to-UART, CAN, I2C, SPI, LoRaWAN, Zigbee), a power source (USB-C 5 V, USB-C PD 12 V, 5/12/24 V barrel jack, solar, single- or multi-cell Li-ion/LiPo, 2xAA cells) and an application context (consumer, industrial or automotive).
The product is positioned by the company as an "AI hardware engineer" that works in four stages: planning from stated requirements, research plus bill-of-materials and schematic generation, AI-assisted part placement and routing under user constraints, and manufacturing outputs with sourcing-aware part suggestions. The company states the AI checks in with the engineer at decision points and that its actions are explainable, reviewable and reversible. Platform capabilities described include live component data covering inventory, pricing and alternates; real-time collaboration with version control and permissions; automated design rule checks, supply chain monitoring and manufacturability validation; forkable public projects and templates; and access from any device without installation.
Flux presents its scope as spanning prototypes through production-ready boards, with application categories including IoT and mesh devices, embedded AI, adaptive robotics, audio and signal-processing modules, RF and telemetry, power delivery systems, industrial automation, and hardware accelerators.
Founding story
The founders state that they created Flux because building hardware remains far harder than building software — high costs, significant risks and long timelines when working with physical products — with the stated aim of making "atoms as malleable as bits" and lowering the barrier to building electronic devices.
Business model
Flux provides its PCB design tool as a browser-delivered software platform used directly by engineers, with a free entry tier advertised on its website ("Free to start") and collaboration features such as version control and advanced permissions aimed at teams.
Traction
The company's website reports 1,099,361 builders, 6,425,482 projects and 821,334 components on the platform, and states that it is partnered with manufacturers.
▸Full profile — market position, technology, go-to-market
Market position
Flux positions its browser-based, collaborative, AI-assisted eCAD as an alternative to conventional installed PCB design software, describing itself as offering "the world's first AI hardware engineer."
Stated points of difference include browser-native design with no downloads and instant sharing, real-time multi-user collaboration with version control and permissions, AI actions that are explainable, reviewable and reversible with the engineer retaining final decisions, component-level live inventory and pricing data feeding the BoM, automated guardrails for design rules, sourcing and manufacturability, and support from engineers plus a builder community.
Technology
The platform is a full browser-based eCAD environment requiring no local installation, combined with AI workflow agents that interpret natural-language build requirements, produce a design plan, conduct research, generate bills of materials and schematics, and place and route layouts while respecting user-defined constraints. It integrates live component data (inventory, pricing, alternates) into the BoM, and runs automated design rule checks, supply chain monitoring and manufacturability validation. Outputs are prepared for fabrication.
