Wales Changed the World

From the first industrial nation to the technology behind the internet — Wales has always punched above its weight.

By 1851, Wales was the world's first industrial nation — the first country where more people worked in industry than agriculture. Swansea smelted one-third of the world's copper. North Wales produced one-third of global roofing slate. Merthyr's ironworks powered the British Empire. We invented the ball bearing, the hydrogen fuel cell, packet switching for the internet, and the eight-hour workday. We gave the world Viagra, radar, and the first mail-order business. Given that legacy, Wales should be among the world's wealthiest nations. It isn't — yet. Cymru Compass exists to help every Welsh business get found, because the next chapter of Welsh innovation starts with the businesses we have today.

🌐

Packet Switching

Donald Davies built it in Wales — the technology that makes the internet work.

Ball Bearing

Philip Vaughan, 1794.

🕓

Hydrogen Fuel Cell

Sir William Grove, 1842.

🚚

First Passenger Railway

Mumbles Railway, 1807.

📧

Mail-Order Business

Pryce Pryce-Jones, Newtown, 1861.

📅

Copper Capital

Swansea smelted one-third of the world's copper.

🛠

Slate Capital

North Wales roofed the world — now a UNESCO World Heritage Site.

👥

Eight-Hour Day

Robert Owen from Newtown pioneered the cooperative movement.

41,000+ Welsh businesses are listed here. The next great Welsh innovation could be one of them.
