This week on CUTalks we are talking to Daniel Valdivia and Chris Rosser. Daniel is the CEO and Chris is the CTO, and together they co-founded Unlimitech, a fitness technology startup developing the Smartmask, which is a wearable designed to measure aerobic and metabolic efficiency metrics by tracking breath flow and composition. Daniel has a background in business engineering as well as an MBA from Cambridge, and Chris is an engineer by training, with subsequent engineering consultancy roles.
