Set up in 2009, 15 Marketing Limited focuses on marketing and e-gaming management. It provides a wide range of services to clients including SEO, emailing, social media, network management, white label management and affiliate management. It is thought the company developed Jumpman Gaming, though this isn’t confirmed.

 

15 Marketing Limited has its own bingo network known as ‘15’. This includes 10 different bingo brands. It also has numerous white label bingo sites powered by various software providers.  Just some of its clients include ‘Ready, Set, Bingo’, ‘OhMyBingo’ and ‘Scratch Stars’. It doesn’t have a bias over any particular software and it even has its own bingo portals.

Editor-in-Chief at Top Online Bingo Sites

Zena Grantham has been part of the Top Online Bingo Sites team since the very beginning, making her one of the site's longest-serving contributors. As news editor, she is responsible for the majority of our coverage — from operator reviews and new bingo room launches to UKGC enforcement actions and record-breaking jackpot wins.

With well over 15 years of experience in the UK gambling sector — and a particular focus on the online bingo market — Zena has an encyclopaedic knowledge of the operators, the games, and the players. She tracks everything from licensing changes and operator consolidations to emerging trends in bingo room design, and her reporting keeps readers ahead of the curve on the stories that matter.

Zena's writing is grounded in accuracy and a genuine understanding of how the industry works — both for operators and players. Whether it's a £3.6 million jackpot win or a major policy shift from the Gambling Commission, she makes sure the facts are straight and the context is clear.
