The Role

About MAGIC AI

MAGIC AI is an elegant in-home health coach that utilises computer vision, connected weights, and 3D cameras to provide personalised training sessions led by world-renowned athletes. We have gained recognition and exposure, being stocked in Selfridges, featured on Good Morning Britain, and listed as one of Fast Company's World's Most Innovative Companies of 2024. With just a small team, our company achieved a substantial revenue rate during its first financial year.

MAGIC AI is the pioneer in offering users the opportunity to perform exercises in front of an intelligent hologram mirror. Our cutting-edge proprietary computer vision software enables real-time form correction, rep counting, and live feedback, resulting in a fully customised workout experience. We have also collaborated with top athletes to create exclusive workout content, revolutionising the way users can be trained in sports, strength training, yoga, dance, and more. With us, individuals can benefit from personalised tracking and feedback, as if being privately coached and corrected by the world's best, without the hefty fees typically associated with personal training.

We have secured venture capital funding from prominent multi-billion-dollar VC funds, who have also invested in well-known companies such as Grover, Scalapay, Onfido, as well as notable founders and angels from Spotify, Stripe, Facebook, Hopin, and Tough Mudder.

What We Do

MAGIC uses computer vision, connected weights and 3D cameras to deliver personal training by the world's best athletes at home. MAGIC is the first in the world to allow users to perform exercises in front of an intelligent hologram mirror which uses our own custom computer vision software to correct real-time form, rep count, and give live feedback to give a completely hyper-personalised workout. We have combined this with our patent-pending dumbbells and co-created workout content with the world's leading athletes. Similar to how Masterclass.com has done for the higher arts, we enable anyone to be coached by the world’s best in sport, strength, yoga, boxing, dance etc. Users get 1:1 hyper-personalised tracking and feedback as if being personally trained + corrected by them -- but without having to pay £100s a week in typical personal training fees. We are stocked in Selfridges, were named Techround’s #1 IoT startup 2021 and were recently backed by Virgin Startup. We are venture capital backed by 2 leading multi $billion VC funds who also invested in unicorns: Grover, Scalapay and Onfido as well as the founders/angels from Spotify, Stripe, Facebook, Hopin and Tough Mudder.
