Hello, I'm Lily Wen, the founder of Circuit Butler.

Before starting Circuit Butler, I spent several years working inside one of the world's best-known PCB manufacturers, PCBWay. During that time, I was deeply involved in every step of the process: PCB fabrication, component sourcing, and SMT assembly. I know exactly what it takes to turn a Gerber file into a perfectly functioning PCBA board, quickly and reliably. I know which fabs have the most consistent ENIG finish, which assembly houses have the most experience with BGA packages, and how to work efficiently with major suppliers like Digi-Key or Mouser to get the right parts at the right price and lead time.

I love this industry, but I also see the struggles that many hardware engineers and startup teams face every day.

Does any of this sound familiar?

The "Customer Support Void": You have an urgent technical issue, but you're stuck dealing with a standardized ticketing system, unable to speak directly with an engineer who can solve your problem.

Hidden Costs: You get a quote, but you can't be sure if the proposed process is optimal or if a component substitution is truly equivalent. You have no choice but to accept it and hope for the best.

The "Small Order" Struggle: Your prototype run of 50 or 100 units is just one of thousands of jobs in the queue. Your order doesn't get the attention or flexibility it deserves.

I've seen these pain points firsthand. I created Circuit Butler to solve them.

Circuit Butler: Not a Broker, but Your Project Butler

My model sounds simple: when you place an order, I leverage my network of trusted supply chain partners—the very same fabs, component distributors, and assembly houses that serve major players like PCBWay—to complete your project.

But this is not just a "reselling" service. My core value is translating my years of insider experience into a dedicated, personalized "concierge service" for your project.

This means you get:

Expert DFM Analysis: Before your board hits the production line, I will personally review your design, offering professional feedback to mitigate manufacturing risks and optimize for success.

Transparent Supply Chain Management: I will select the best processes and suppliers for your specific project needs, keeping you informed and in control at every stage.

Direct-to-Founder Communication: You have a direct line to me. No support tickets, no miscommunication. We work together as one team.

An Invitation You Can't Refuse: Become Our Founding Partner

To validate and perfect our end-to-end service, I am officially launching our "Founder's Program." I am looking for three early-stage partners to build their next project with me.

In return for your partnership, you will receive:

✅ Your First Order at Cost (Zero Profit): I will provide full transparency on all supply chain costs (PCBs, components, assembly), and you pay only that amount. This may be the most cost-effective, high-quality PCBA service you will ever find.

✅ Direct Service from the Founder: I will be your dedicated project manager from DFM to final delivery, ensuring your project gets the expert attention it deserves.

 🤝 Become Our Official Case Study: If you are satisfied with our service, we hope to feature our successful collaboration as one of Circuit Butler's first official case studies (all details regarding confidentiality and what we can show will be agreed upon with you beforehand).

Who is this program for?

Project Type: Prototypes or small-batch runs of up to 100 units.

Project Status: Your design is mostly complete and you're ready to launch this week or in the near future.

Our Ideal Partner: An engineering team or individual who values quality, communication, and is excited to grow with us.

How to Apply

There are only 3 spots available.

If you have a suitable project and are interested in this partnership, please send me an email today at: [email protected]

Please use the subject line: [Founding Partner Application] + Your Project/Company Name

In the email, please briefly introduce your project. If possible, attach your Gerber files and Bill of Materials (BOM) so I can provide a fast and accurate assessment.

I firmly believe that professional, personalized service shouldn't be reserved for high-volume orders. Every successful prototype is the beginning of a great product.

I look forward to building something amazing with you.

Best regards,

Lily Wen
