About Inrange

Our story

Our story starts a long way from the first tee. Because our technical team honed their skills developing the world's most powerful radio telescopes, helping to discover the origins of the universe itself.

But as (amateur) golfers, they saw another way to use the same technology. Not just to make something more accurate (though it is), and not just to make practice more fun (though it does), but to do something bigger.

To use technology, combined with the more informal environment of the range to open up the game of golf. To make practice fun again. To bring in a whole new generation of players. To redefine what 'playing golf' actually looks like.

About Inrange

How we work

Everything we do is underpinned by 5 simple principles. If an idea aligns with them, we run with it. If it doesn’t, we don’t.

Progression through fun.

Enjoyment and improvement go hand in hand. The way to bring new players to the game is to give them an unforgettable first experience. Just as the best practice – and the only kind that works – happens when you have fun.

Golf is for everyone.

We design for the needs of EVERY level of performance, from complete beginner to scratch golfer – and enable different abilities to enjoy the game together. It's only fun when we're all having fun.

Partner not product.

What we make is nothing without the range itself. We produce a physical product, but we take it to market through partnership. We’re here to help our partners grow through delivering a great playing experience.

Magical simplicity.

We work tirelessly on the technology so that for the user and the range owner, it disappears behind a playing and management experience that’s intuitive, effortless and magical.

Technical perfection.

Approximate isn’t good enough. ‘Good enough’ isn’t good enough. We strive for technical perfection so that we see every single shot. So our range partners never have to worry. So serious players can trust our data. So social players can brag with confidence.
