ScreensConcept
Desktop and mobile: PCB designers do detailed circuit board work at desks with large screens, but also review designs and collaborate on tablets or laptops in the lab or field. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Copperroom is a PCB design workspace that runs in the browser. Open a project on any laptop or tablet, with nothing to install. It reads and writes KiCad project files, so existing boards come in and go out unchanged.
Teams work on the same board at the same time. Each person sees the others' cursors, leaves comments on a footprint or a net, and can step back through earlier versions. You share a view-only link with a manufacturer or client instead of sending zip files.
It is for small hardware teams, freelancers and hobbyists who now trade files by email or manage them in Git. The first version covers the core flow: schematic, layout, review and export.

- Why this name
- Copper is what a board is made of, and a room is where a team works together. Two plain words in one name.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Runs in any modern browser
Open schematics and layouts on a laptop, tablet or borrowed machine. No installer, no library setup, no version mismatch between teammates.
No member yet
KiCad file import and export
Bring in existing KiCad projects and export them back, so the team is never locked in and can keep using the desktop tool.
No member yet
Live co-editing
Several people edit one board together. Cursors and changes show as they happen, with clear locks on traces being routed.
No member yet
Comments pinned to the board
Attach a question to a part, a net or a spot on a layer. Assign it, resolve it, and see open items before release.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users send view-only board links to clients, fab houses and forums. Viewers see the board in the browser, with a Copperroom mark and an option to open a copy of public projects.
- Do they become customers?
- Viewers are often engineers who design boards too, so some may sign up. Test how many link viewers create an account and how many then start a project of their own.
- First customers
- Small hardware startups and consultancies with 2 to 10 engineers who already use KiCad and trade board files by email or Git.
- Where to reach them
- Hacker News and hardware forums: Post a working demo with a public board anyone can open and edit, and answer questions from KiCad users.
- Open hardware communities: Offer free hosting for public projects and ask maintainers to link their boards for review.
- Direct outreach to small teams: Contact hardware consultancies and offer to move one live project into Copperroom for free.
- First milestone
- Five small hardware teams pay for private projects within 60 days of launch, and each uses live editing or review weekly.

RisksAI inference
- TechnicalFull-featured routing, design checks and large-board performance in a browser are hard. The first version may cover only part of what KiCad does, which could disappoint power users.
- Intellectual propertyBuilding on KiCad code and libraries brings open-source license duties. The license terms and the KiCad name and logo rules need checking before launch.
- CommercialUsers may be happy with desktop KiCad plus Git and see no reason to pay $30 per month. Willingness to pay for collaboration is untested.
- DataCompanies may hesitate to put unreleased hardware designs on a hosted service. Security and export options will be asked about early.
- TechnicalRound-trip fidelity with KiCad files is hard. Any lost detail on export would break trust quickly.
