Flux is an AI-powered, browser-based platform for designing electronic hardware and PCBs. It uses natural language prompts to generate plans, schematics, and bill of materials, and can place components and route traces, with automated design rule checks and support for up to eight layers. It includes collaboration features with version control and permissions, plus integrations with distributors and manufacturers to keep parts sourcing-aware. The goal is to make hardware development as fast and iterative as software development, enabling complex boards for IoT, wearables, and robotics by unifying design, sourcing, and manufacturing in one platform.

Flux Enterprise raised $37M to take the hard out of hardware. Hi everyone,. Today Flux Enterprise is excited to share that Flux has raised $37M in new funding led by 8VC, with participation from bain capital ventures, liquid 2 ventures, and outsiders fund, alongside lenny rachitsky, john lilly, and tom preston-werner and many other world-class operators. Flux Enterprise raised this capital for one reason: to accelerate its mission to take the hard out of hardware and keep pushing until building hardware feels as easy and iterative as building software. Flux Enterprise started Flux with a simple belief: hardware design should move faster, feel more collaborative, and fit the way modern teams actually work. Flux Enterprise were also excited about what AI could unlock for hardware as early as 2019, back when that was not the obvious bet. Looking back, Flux Enterprise were very early, frankly too early, and only a few of the use cases Flux Enterprise envisioned were really possible at the time, at least not reliably and not at the scale serious teams need. Looking back, Flux Enterprise is glad Flux Enterprise started early. It gave Flux Enterprise time to lay the foundation and build Flux to be AI-first before it was the obvious move. When LLMs hit their stride, Flux Enterprise were ready to plug them in quickly and learn by shipping. Flux Enterprise listened closely, fixed sharp edges, hardened the platform, and iterated until Flux started to feel like the tool Flux Enterprise always wanted to use. If you stuck with Flux Enterprise and kept sending feedback, thank you. That feedback is a big part of why the product is meaningfully better today. To date, 1,099,361 builders have used Flux to create 6,425,482 projects, and this raise gives Flux Enterprise the resources to move faster and to help more builders move through the hardware workflow with less friction. What this funding accelerates. This funding lets Flux Enterprise move faster on the parts of Flux that matter most for serious work. Here are the three areas Flux Enterprise is investing in with this additional funding, and what it means for you. 1) A more capable AI hardware engineer. You can already direct Flux with prompts and have it execute multi-step workflows. With this funding Flux Enterprise is making it faster, more capable, and more reliable, and Flux Enterprise is also making it easier to use so you can get more done with fewer steps. Trust is everything, so Flux Enterprise is making the agent more predictable and clearer about when it is uncertain. You should know when to trust it, when to verify, and when to step in. You steer, Flux executes, and you stay in control. 2) A more robust eCAD platform for complex boards. Flux Enterprise is investing in the core platform so you can design complex boards with confidence. That means better performance at scale, fewer frustrations, and output you can trust when it is time to build. The AI uses the same editor you do, so every platform upgrade also upgrades what the agent can do. 3) deeper ecosystem integrations. Hardware is a team effort, and the tooling needs to fit into existing workflows. Flux Enterprise is already connected with many popular distributors, and Flux Enterprise is doubling down on building a robust parts library grounded in real availability and real workflows. As integrations mature, Flux Enterprise'll keep expanding what Flux can connect to, including manufacturers, simulators, and the tools your team relies on. Flux Enterprise'll follow demand. Flux Enterprise can't do this without you. None of this exists without you. If you've given Flux Enterprise feedback, pointed out sharp edges, shared projects, or stuck with Flux while Flux Enterprise earned the right to be part of your workflow, thank you. If you want something improved, whether that is agent behavior, eCAD capabilities, or ecosystem connections, tell Flux Enterprise. Flux Enterprise read it all and it directly shapes what Flux Enterprise prioritize. Flux Enterprise is going to keep shipping. Thank you for being here.

10x faster & self-correcting: feb 2026 update. Since Flux Enterprise launched the new Flux agent last october, you've used it over 900,000 times to design buck converters, debug power nets, swap components, and build entire schematics from a prompt. That usage showed Flux Enterprise exactly where to focus: speed, correctness, and reliability. So Flux Enterprise rebuilt the agent from the ground up with a new architecture, execution model, and verification system. Login to try the updated agent today! Here's what changed. Better at checking its own work. The agent now does a better job checking its own work as it goes by, continuously running ERC and DRC checks against the design, catching floating pins, missing connections, and rule violations in real time. The result: cleaner schematics on the first run, fewer manual fixes, and fewer wasted credits. More adaptive & self-correcting. The agent no longer follows a fixed plan from start to finish. It evaluates progress after each step and course-corrects along the way. If it hits a conflict or finds a better path, it updates its plan and keeps going. Ask it to drop in a single component, and it stays lean and fast. Give it a full power management system, and it will work through the complexity iteratively until the design passes its checks. That means more complete, more correct results across a wider range of tasks. Up to 10x faster. All of this happens in parallel. The new agent places components, routes connections, and verifies results at the same time, collapsing what used to be a long sequential pipeline into a fraction of the time. Complex jobs that previously took 30+ minutes now finish in under 5. You spend less time waiting and more time iterating on your design. Faster completion and fewer retries also mean your credits go further. And Flux Enterprise has done all of this without raising prices. Flux Enterprise ran the same prompts on the old and new agents. The results speak for themselves. Speed varies by complexity. Simple tasks like adding a component finish quickly. Larger operations like generating a full power management system take longer, but are still dramatically faster than before. Other improvements. Flux Enterprise also shipped several improvements alongside the new agent, all focused on the same goal: helping you build hardware faster. * Library tool (@library): faster searches, smarter follow-ups, and better alternate component selection. * Schematic auto-zoom: Flux now adjusts your viewport while the agent works so you can watch your project come together in real time. * Schematic editor: legibility and experience improvements across the board. * Reviews: new Electrical Rule Checks (ERCs) to give you and the agent better awareness of issues to fix. What's next. This release focused on speed and correctness, but Flux Enterprise is not stopping here. Up next: even better verification loops, more tools for organizing complex projects, continued schematic legibility improvements, and further Auto-Layout upgrades. Lots more to come. Lance cassidy.
