About us
Rider’s Positions’ vision is to improve the rider’s position in the saddle and create a perfect interaction between equestrian rider and horse. We have developed the app “Rider Analysis” that measures the rider’s position during riding by using a mobile phone. The rider receives advice on how to improve his or her position. This supports riders to structure their training and focus on points of improvement to enhance their riding experience and prevent injuries of both the rider and the horse.
The founders of Rider’s Position, Mari Zetterqvist Blokhuis and Charlotta Mantell, are both passionate riders and horse owners with a special interest in the interaction between rider and horse. The connection between Charlotta and Mari began many years ago, when Charlotta was grooming Mari’s dressage horse named Gavott. Their paths crossed again In 2019 when, with renewed enthusiasm and a glimpse of the potential of their combined skills, Charlotta and Mari decided to team up and so Rider’s Position was born – a harmonious fusion of experience, talent and love of riding. Enjoy the ride with us!

Charlotta is 12 years old with Mari’s horse Gavott.
Meet Charlotta her journey with horses began at the age of eight at a riding school, where she quickly fell in love with horses and riding.
Before entering the equestrian world full-time, Charlotta had a successful career as Head of Experience Center and Creative Director at Ericsson, a leading telecom technology company. Despite her success, she longed for something more meaningful – something that could combine her technical expertise with her passion for horses.
She came up with the idea for Rider’s Position after thinking about how objective measurement could improve her rider’s feeling and thus the interaction with the horse. Together with Mari Zetterqvist Blokhuis, she founded Rider’s Position, which uses the latest technology to analyze the rider’s seat and position. By giving riders objective feedback, Rider’s Position helps to create better balance, stability and harmony in riding.
Charlotta now has her own horse, Big Dream, who is actively involved in the company. He helps to test and collect data and contributes with insights on how data-driven riding can improve communication between rider and horse.His involvement allows the technology to be developed from the horse’s perspective, further strengthening the interaction and understanding between horse and rider.
Together with Mari, Charlotta has recently introduced the Rider’s Position Coach, a tool that further enhances the rider’s understanding of their own body and its impact on the horse.Combining her technical background with her passion for riding, she strives to improve the interaction between rider and horse, leading to a more rewarding and harmonious riding experience.
