The Team Behind the Best Boating App!

Find out more about the passionate team of sailors and computer scientists that are the brains behind savvy navvy.

Jelte Liebrand - CEO & Founder of savvy navvyJelte Liebrand
CEO & Founder

Jelte took part in the Clipper Round the World yacht race in 2014. He had plenty of sailing experience, but racing from San Francisco to New York was quite a bit different from anything he'd done before. Sailing thousands of miles off-shore, he learnt how difficult navigation can be. Updating charts, downloading weather forecasts, predicting boat speed, avoiding squalls with 50+ knots of wind; it all took hours and hours below deck, plotting courses on a computer whilst hanging on at a 45 degree heel. Jelte became convinced there should be an easier way.

He spent two years researching and building the foundation for savvy navvy and in July 2017 he left his job at Google to get his vision of easy, safe navigation out to every sailor on the water.

Kevin O'Neill - Co-founder and Commercial DirectorKevin O'Neill
Co-founder & Commercial Director

Kevin and Jelte go back 18 years, when they worked together for Symbian, creating the mobile operating system of the (then) future.

Having travelled the world for work and pleasure and worked in many industries for large companies, Kevin realised that what he really likes is working in small teams where he can be really hands-on and make a meaningful contribution. So when Jelte explained his vision for savvy navvy, Kevin jumped onboard immediately.

He has broad business experience including energy, chemicals, hardware and software. He especially enjoys interacting with customers of many lands and solving new problems. He is also a textbook neophyte sailor who looks forward to testing the company yacht. We haven’t told him we haven’t got one yet.

Prior to joining savvy navvy he worked in various marketing and business development roles for technology companies in both Germany and Ireland. He met Jelte through a network for Google alumni and, after researching the app in more detail, became convinced that he and the team were on to something special. Following weeks of consistent nagging, he managed to convince Jelte to give him a job and the rest, as they say, is history.
