Any aspiring referee in Sussex is lucky to have a lot of inspiring people to look up to, and for Hassan that was no different.
“I always had this memory of when I was a kid, watching the Premier League and seeing Gary Willard, Worthing, on TV, and always remember thinking, 'wow, there's a premier league referee from Worthing'.
“I thought that it was so cool to see someone from Worthing in the Premier League. I just didn't put two and two together. That always stuck in my mind.
“I met him a few years later and he's one of the greatest guys! Him and also, Martin Boddenham, are two guys in Sussex, you could sit there for days and days just talking about football and refereeing, and you wouldn't get bored.
“As I came through, I think what I did, through Worthing RA (Referees Association), was start to meet other people, because when you when you start on your own, it can be lonely. You go out and referee and you're not part of a team or a squad, you don't know anyone.
“Worthing RA really helped. There were people like Keith Brisley, Derek Mansfield and then there was three other guys, a similar age to me, Jack Tracy, who I don't think is referring anymore, Mike Ryan and Jamie wells.
“They were all very different characters, but we started to keep in touch and as you go up the ladder, you start to go out as a team of three, and you start to build relationships with other referees, which is great.
“Mike Ryan, in particular, is someone that has gone on to be one of the highest in Sussex at the moment. He progressed, and it's great to still have the relationship because he will still ask me for feedback on stuff even though I'm a Level 5! But we've just built a trusting relationship and vice versa.”
So how does Level 5 referee, Hassan Rajwani, end up with a business helping referees all over the globe? For that, we go back to his time at University.
“At Loughborough, in 2009, I studied Computer Science, I was very into technology. I remember doing the course and thinking it's strange that with the iPhone's coming out at the time, why are we still writing things down on a piece of paper?
“I had this idea then that, maybe a referee could use their phone to record things that happen in the game, rather than using a piece of paper and pen and I did that for my dissertation.
“It was called iREF at the time, the Interactive Referees Electronic Friend, that was the acronym that I made up because everything seemed to have an 'i' in front of it!
“I got a good mark, and kind of left it there as an idea. I went and worked locally for American Express, big sponsors of Brighton & Hove Albion, ended up doing some work on the websites and mobile apps at American Express, and basically got bored of being in finance.
“Then, the Apple Watch came out and I thought, come to think of it, referees aren't going to run round with a phone, but they would run around with a watch.
“So, I started thinking this could work. Me and a friend of mine began to build the app for the smartwatch, while I was still working at Amex. Then it got to a point where actually, we'll put a video together and we'll run out.
“We went to Worthing FC with Mike Ryan, Jamie wells, and shot a video with Worthing college and created a trailer for what this app could look like. We put it on online, we put it on Facebook and basically lots of people started to show interest. We built the app, and we had about 50 people beta it. That's when I wondered if this could become full time.”
