Madeline McIntosh, Publishing Lead

Madeline is a great enthusiast for solving one of publishing’s ‘big challenges’ – discoverability. From the moment we met, we all focused on how Shimmr’s automated advertising could raise awareness, drive engagement, and convert readers to purchases of formerly un-discovered books, whichever part of ‘the list’ they occupy. As a recent CEO of ‘The Big Five’s’ biggest, Penguin Random House, and current board member of Simon & Schuster, Madeline brings an acute and demanding eye to the development of Shimmr’s product, served up with characteristic constructiveness and ease.  

Richard Charkin OBE, Publishing Lead

Richard is Shimmr’s great calibrator. He helps us to navigate all parts of the publishing industry, adroitly understanding not just the needs of publishers, authors and readers, but also the commercial realities that underpin the industry’s dynamics, so Shimmr can make a meaningful impact. He is a former president of the International Publishers Association and the United Kingdom’s Publishers Association, executive director of Bloomsbury, as well as holding many senior posts at major publishing houses, including Macmillan, Oxford University Press, Current Science Group, and Reed Elsevier.

As a former Chief Strategy Officer at Dentsu, and CEO at Carat Media, Matthew has steered innovation and optimisation of effective media use throughout his career. At Shimmr, in the post-cookies world of contextual targeting and performance marketing, Matthew ensures we’re connecting to all the right platforms in a knowing and effective fashion, extracting exceptional value from media budgets, to ensure our cost-effective subscriptions deliver impressions, engagement and conversions with remarkable returns. Matthew is irritatingly good at predicting football scores, too.  

Steven van Niekerk, Head of AI Engineering 

Steve leads the integration of AI into all that Shimmr does, from analysis to generation to deployment. In this role, Steve discovers and evaluates everything happening in the world of AI, ensuring Shimmr is availing of the best models and innovations.

Steve is highly active in Scouts leadership, and knows how to get things done! 

James Mitchell, Marketing Director 

James leads Shimmr’s communications, identifying and executing marketing activities to ensure the company is salient and relevant to the book publishing industry in all it does. He also leads our events presence, which gives him an excuse to wander the halls in a charmingly promiscuous out-reach to customers who unfailingly welcome him. His career spans being a copywriter, brand leader, PR-agency leader and being part of the founding team of a social media app. As well as keeping Shimmr’s marketing humming, James is an indefatigable nick-namer, reliably reducing the team to tears with his apt characterisations of everyone with whom he interacts. Don’t worry, they’re always respectful!  

Justin Milicevic, Quality Assurance & Automation Engineer 

Justin is responsible for ensuring everything works. This window on that browser. This download to that folder. All the nitty-gritty detail of delivering a delightful experience on the screen and in functionality is inspected and passed by Justin.

Jolene van Niekerk, Operations Manager 

Jo helps to manage our operations – from ensuring we properly keep data in our customer relationship management platform, to knowing that we’ve completed compliance tasks in good time and keep necessary records across jurisdictions and regulations. It’s a complex business serving data across the world, and sometimes it takes a mind trained by raising 4 children to multi-task it all in an effective way!
