It’s partially my fault for trying to set up this interview right in the middle of transfer season, which is a particularly chaotic time for him. When we manage to catch up, he’s just landed in Barcelona from London, and is flying straight out to Brazil the next day. He’d been in London capturing footage of Noni Madueke for his transfer to Arsenal, and he’s heading out to South America to film lifestyle content of Dutch international Memphis Depay before the new season begins.

Jack isn’t always being flown out to these places by big brands, advertising agencies or football clubs. His clients are more often the players themselves, who hire him to make high-end video content showcasing every aspect of their personal lives. His videos often resemble high-fashion adverts or big-budget movie trailers – expect private jets, diamond-encrusted chains and far-flung locations, all inter-stitched with players in the gym or on training pitches showing off their skills. The videos appear on the players’ social media feeds, but they’re not promoting any particular campaign or brand – in this world, footballers are the brands.

This kind of self-promotion is a reasonably new phenomenon, brought about by the influx of social media and spurred on by the sheer amount of wealth footballers are now accruing. Jack also thinks that footballers considering their careers beyond the pitch plays a role. “A footballer’s career is actually really short,” he says. “After 35 or so, it’s over. They feel like they have to build their own brand, thinking about their life after football and how they want to be seen.” And if Jack’s work is anything to go by, how they want to be seen is less about the daily grind of football and more about luxury – from fashion to jewellery to travel.

Things weren’t always so international and glamorous for the Swiss native, who started out planning on becoming a professional footballer himself, training and playing for small local club FC Wetzikon. An injury at 18 meant a break from the game and space for a new interest to begin blooming. “During that time, I bought a proper camera and started making travel videos wherever I went,” he explains. “I also started filming a friend I trained with, Stephan Seiler, who ended up playing professionally in Switzerland. That meant more players saw my videos, and I started getting more requests for work.”

In his role documenting these players’ lives, Jack is no stranger to private jets. He once spent an entire summer with Memphis Depay when he was playing for Barcelona, flying all over the world with the footballer for content. “We started in the Netherlands, then we flew to Ghana, then we went to LA, the south of France, and then back to Barcelona,” he says. Depay’s side career as a musician and high-roller lifestyle makes him, in Jack’s words, “the perfect client”. The resulting videos from that trip are full of drone footage of swimming pools, tracking shots of luxury cars and close-ups of expensive watches and clothing, all interspersed with clips of Depay looking every inch the superstar with a side gig as a rapper. “He’s really photogenic!” Jack points out. “He’s also really into fashion, so he changes his clothes a lot. In one day with him, I can shoot content for two weeks because he changes his outfits and looks different.”

For footballers aiming to curate a personal brand and control their image, this level of intimate access is rare. Jack’s close relationships with these players have been built up over time and he believes they are instrumental to his success. “I think the most important thing in this job is trust,” he says. “You have to understand how a footballer thinks. Nowadays, one bad thing they do can be a massive thing the next day in the media, so trust is the number-one thing.”

One player who trusts Jack implicitly is winger Noah Okafor, who has just transferred to Leeds from AC Milan, and whose Instagram feed is full of glossy videos and pictures in Jack’s signature style. The two recently took a trip to Greece together, where Jack created content of Okafor on training pitches, boats and jet skis. “We know each other very well,” Okafor says when asked why he likes working with Jack. “In a job like this, that friendship is really important because you can feel more comfortable and free, and you can really be yourself. Then none of the videos we make feel fake.”

As a professional footballer in the middle of his career, Okafor knows that his image is crucial. “It’s really important how you show yourself on social media,” he says. When it comes to the creative direction of his content, he trusts Jack enough to leave that in his hands. “Most of the decisions I just leave to Jack. He knows me and he knows what I like.”

So where next for Jack? Career-wise, he’s focused on continuing to grow Spyders, and he’s recently embarked on a new podcast venture, Say Less, featuring some of his footballer friends as guests. Location-wise? As soon as we hang up our call, he’s off to São Paulo – then where after that is anyone’s guess.
