I spent the last year building a predictive tennis model using Google Sheets which is basically the same as Excel. I have no technical skills so this was the easiest way to do it, plus it helped me learn SQL. Basically I have around 50,000 tennis matches in one sheet, filter them into another sheet, into around 100 comparative points, then in the end produce a probability for each upcoming match, and bet accordingly. I also use it to produce a little head to head stats visual and automated 200-word match previews.

It all works perfectly but obviously just for one user at a time. So I brought on a dev friend a few months ago and will launch a user facing site next week, as well as a b2b api for match previews / seo rich content.

I'm actually looking for seed funding up to around 25k, if anyone wants to reach out about that, or has other questions.

If you just want to follow some of the tips I'm running a very basic blog site at www.tennisacca.com sharing my most highly recommended picks (rather than listing 100's of games a week and needing a huge bankroll), which win at a ROI of 10%+ on average. It's mostly just for friends until the main site launches next week.

Hi! I did something similar a few years ago,instead I used python and machine learning algorithms + custom ELO implementations for tennis matches. Unfortunately it worked too well and I was banned from all the bookmakers.

nice, well done! Why not use betfair or Molly? Or also sell tips etc? Do you have a site?

Out of curiosity. How did you manage to gather so much data?
