Jon Craton

Jon brings to the business over 30 years of experience covering a variety of software and hardware industries. His technical background, combined with extensive experience of sales, marketing and general management, allows him to make a substantial contribution to Rosa’s success. In 1996 Jon co-founded Cramer and was CEO of the business for 6 years, leading the company through two stages of VC financing that raised over $27 million of capital for the business. Thereafter he was a senior executive with the company until its sale to Amdocs in 2006 for $425m in cash. Since then Jon has been a founding or early stage investor in a variety of start-ups - including Creo Medical (surgical technology), SwiftKey (artificial intelligence) and Zynstra (cloud computing). 

Prof. Dek Woolfson

World leader in protein design with extensive track record of commercial partnerships. In 2011 and 2014 Dek’s group published landmark papers in Nature Chemical Biology and Science describing a new protein structure, which they called alpha helical barrels.  These have central channels that allow binding and fluorescence change upon binding by analytes or complex mixtures.  This provides the basis for the barrel-array diagnostics and sensing (BADASS) technology that underpins Rosa Biotech’s activities. Dek is the founding Director of BrisSynBio – a £13 million Synthetic Biology Research Centre – and the Bristol BioDesign Institute at the University of Bristol. His work has been featured in Nature Chemistry (cover story), Nature Chemical Biology and Science. He is the recipient of multiple science awards from bodies including the Royal Society and the Royal Society of Chemistry.
