About Leon Gordon

Hello! I’m Leon, founder and CEO of Onyx Data. There’s one thing that every business has but only few are taking advantage of - and that’s data. I’ve witnessed first-hand the power that leveraging your data can have when it comes to solving problems for your business or supercharging its growth. That’s why I decided to launch my own company, dedicated to helping businesses like yours unlock the maximum power of their data. We offer full-scale data management strategy as well as ad-hoc consulting services. Data literacy is a big priority of ours at Onyx, and so we also run 1-day training sessions in Microsoft Fabric, Excel, Power BI and Azure, amongst others. Here’s are some of the results I’ve helped my clients achieve: → Increased revenue after analysing data to see what’s working, and what to do more of. → Quarter-fold increases in business efficiency.→ Increased profit after figuring out where best to reduce costs.→ Around 35% improvement in data accuracy.→ Improved customer experiences from assessing the buyer journey. → Increases in up to 50% in data literacy across teams. As someone who came from a football background and relied on self-learning to enter the data industry, I also like to give back and offer advice, expertise and monthly challenges through my #DataDNA group. Outside of data, I am a keynote speaker at various tech conferences or events across the globe, where I share my insights and observations from over two decades in the industry. Finally, I am proud to be endorsed by Gartner and accredited as a Microsoft MVP and Forbes Technology Council member. I’m also a regular contributor to top tech publications including Brains Magazine and the AI Journal. Whether you want to finally start using your organisation’s data the right way or are interested in having me speak at your event, feel free to send me a LinkedIn DM or alternatively email me at leon@onyxdata.co.uk.I look forward to hearing from you!
