VitalityLife has promoted Deepak Jobanputra, formerly product and actuarial director, as deputy CEO.
Justin Taurog, formerly distributions and marketing director, has been appointed managing director of sales and distribution.
Jobanputra said: "We are very pleased with the Vitality journey over the last seven years and we are very excited about extending our Vitality proposition to more and more people in the UK.
"This brings with it a means to make people healthier and support intermediaries with new and exciting approach to reach customers positively.
Taurog said: "VitalityLife has focussed on solutions that meet customer's needs and can grow the protection market - the Vitality chassis is unique in helping people improve their day to day wellness and get something tangible back without having to claim.
"VitalityLife has built up a sales team of over 200 people supporting IFAs in the UK grow their business and protect their client's futures.
"This has resulted in us growing to be the third largest insurer in the UK IFA market and our best ever quarter with over £15m new business for the three months to December 2014."
Herschel Mayers, CEO of VitalityLife, said: "The scale of our ambition in the UK protection market is clear, and our recent results show that we are on the path to growth in 2015 and beyond.
"To achieve the level of success we want, we need to have the right team on board. Deepak and Justin have been instrumental in our story to date and their promotions are recognition of the important roles they still have to play in the future of our business."
