Pretty much exactly one month after we had the idea to build Oddshero we are ready to launch into open Beta: https://oddshero.io/
I'm so excited for feedback and still amazed how fast time goes by if you're working on something that exciting.
If you have any question about the product, let me know. And yes, it really works, matched betting is generally a well recognised strategy to win money 100% risk-free. I personally make 300-400 EUR a week with Oddshero :)
We built everything on firestore, cloud functions, with gatsby (my first), and react-create-app.
Gatsby is so blazingly fast, I hope you'll see how quickly the pages load, on desktop and mobile, I'm really happy with the result.
