Olivier Beddows
Co-Founder, CTO and Vice President of Lisk
The global financial crisis helped to make Oliver realize that he wanted to create something of bigger significance than the projects he was involved in at the time. With twelve years of development experience, he understood that digital technology, put into the hands of more people than the elite, can be a powerful tool to make the world more just and honest. Oliver saw that blockchain technology offered great opportunity, but that the platforms available for developers were far too complex. This was when he set out on a mission to lower barriers and support everyone with a vision to apply blockchain technology. Together with his team, Oliver hopes to inspire developers globally to freely create, collaborate and change the way connected systems work today and tomorrow.
