Not exactly a Freetrade competitor but I’ve just come across SportStack - a platform where you can buy shares in professional athletes.
They are launching their Football platform in Q4 this year, the platform works like a sports exchange where you can buy/sell shares in players. The better they perform the higher their shares will rise.
The UI looks very sleek and the team is formed of ex Goldman traders.
Check out the Founder’s Medium post - Why I Left Goldman Sachs To Start a Global Sports Exchange
You can sign up for updates/early access using the link below and get free shares when they launch.
