In 2019, we scratched our heads at the current state of hardware tools. Why did they look like they were designed in the 1980s? Ohhhh they were. 😬

We asked ourselves... what if we started from scratch? What if designing hardware was seamless, intuitive, even delightful? What if we could automate all the mundane work? That was our dream.

Fast forward three years, and boom! We opened up to everyone. Since then, the numbers have been wild. Over 100,000 of you have joined, creating a whopping 177,000 projects! And shout out to the 3,200 businesses riding this wave with us. We've even got PCBs designed in Flux going to space soon! 🚀

Let’s take a look back at some of the company’s major highlights that you helped us fulfill!

Milestone #1: Emerging From Private Beta

From the very beginning, we always knew that Flux was only going to be as successful as the community that we built around it. That’s why we started with a private beta: so that we could build a tight-knit community of people who shared the same vision as us as we grew the product. If it weren’t for that group of beta users in the very beginning, we would not be here with you today.

In February 2023, we took our next big step when we emerged from private beta. For the first time ever, anyone in the world was able to test out Flux, and the response was overwhelming. This was our first major step towards our ultimate goal of truly democratizing hardware design for everyone.

Milestone #2: From World’s First AI PCB Design Assistant to Generative AI

We’ve always sought to take the “hard” out of hardware, and it was obvious that existing tools came up short of that vision. We knew we had to think bigger, which is why we came up with Flux Copilot: the industry’s first and only AI PCB design assistant.

When we introduced Copilot, its capabilities were unprecedented, and the response from YOU was fantastic. Over 15,000 users have now worked with Copilot, and it’s tackled a whopping 130,000 questions.

But we didn't stop there. Copilot evolved to not just provide feedback but to take action for you. With Copilot’s ability to wire up schematics for you, users were finally able to avoid the tedium of wiring schematics and spend more time on what really matters. We want to put the magic back in hardware design, and generative AI with Copilot has been one huge step toward that goal.

Milestone #3: Let's Celebrate With Our Users

Meet Gerald, a software engineer behind Vendo King Manila, a vending machine business in the Philippines. Before Flux, he struggled with jumbled boards and too many jumper wires. With no prior PCB design experience, Gerald dived into Flux and crafted his own board. He says, “With Flux, I made our PCB easily. No more wire mess or production problems!” That's a big win! 🚀

Then there's Robert, a software engineer who loves computers, old-school games, web development, and 3D printing. He's the guy behind ControllerAdapter.com, making cool stuff for game controller fans. Thanks to Flux, Robert easily designs and shares his creations.

The Best Has Yet to Come

Looking back at the last four years, it’s amazing to see how far this community has come together.

While what we’ve done has been transformative, what’s really exciting are the infinite possibilities that lie ahead of us. We’re currently exploring the very edge of AI's capabilities in hardware design, and who better to do it with than our incredible community?

We have some exciting things planned for the future, and one thing is for sure: the best has yet to come.

Go 10x faster from idea to PCB
Flux is an all-in-one EDA. Use re-usable blocks, scripting, and a library you don’t have to manage to dramatically reduce the time it takes to go from idea to prototype.
