About the company

ForwardKeys is an innovative travel analytics company. The company was established in 2010 when the founders realised that the air reservation data used by airlines could serve every industry with an interest in global travellers. Since then, we have built an online platform on which our clients monitor and qualify traveller flows, map global demand and forecast travel trends. We are now 50 people strong and growing: always looking for new datasets to develop new products helping our clients understand the travel landscape.

Company culture

Working at ForwardKeys is fun, international, challenging and flexible. Fun is having lunch together (every day), going for after-work drinks or our regular company party. International because our employees come (and work) from all around the world, just like our clients. Challenging is making the step from a start-up to bigger company and everything that includes: from product development to selling them. Flexible means we understand that doing your job well is more important than being in the office every day from 9 to 5.

The job location

Based close to the city centre of Valencia, we have got new offices with a view looking directly at the City of Arts and Sciences. In other words: this is a fantastic opportunity to spend some years on the sunny Mediterranean coast.
