Hostelworld is the world's leading Social Travel platform - a social network-powered OTA on a mission to help travellers find their people and create unforgettable moments together. Founded in 1999 and headquartered in Ireland, we're a team of around 270 people serving hostel partners across more than 180 countries.
Since launching our social network in 2022, we've welcomed over 3.4 million social members who aren't just booking trips, they're messaging, finding events, meeting up and becoming powerful brand advocates. This community generates a rich proprietary dataset of 16 million+ chat messages and 17 million bookings, powering AI-driven personalisation and network effects that no generalist OTA can replicate.
We are not just another OTA - we created an entirely new category – Social Travel. If you want to shape the future of travel by putting people and shared experiences at the heart of it, you'll fit right in here - Learn more about our Team!
At Hostelworld, our culture is a direct reflection of our customers: adventurous, curious, and social. We have a shared love of travel that fuels our work and connects us on a deeper level. It’s a fast-paced environment that blends the agility and "scrappy" resourcefulness of a start-up with the experience and ambition of a global, publicly listed company.
We are a team of pragmatic optimists who are data-obsessed and results-driven. We value a ‘test and learn’ mindset, encouraging experimentation and empowering our teams to take calculated risks. We believe in doing the right thing—for our customers, our partners, and each other. We foster a supportive and collaborative atmosphere where diverse perspectives are celebrated, and where every team member has the opportunity to make a significant impact on our journey. We embrace the journey, not just the destination, and we seek leaders who will thrive in a dynamic environment and inspire their teams to do the same.

Hostelworld Group PLC a ground-breaking social network powered OTA focused on the hostelling category, with a clear Mission to help travellers find people to hang out with.
Our Mission statement is founded on the insight that the vast majority of travellers go hostelling as a means to meet other people; which we facilitate through a series of Social features on our platform that connect our travellers in hostels and cities based on their booking data.
To date the strategy has been extraordinarily successful: accelerating revenues beyond pre pandemic levels, generating significant word of mouth from our customers, and strong endorsements from our Hostel partners. As a consequence, we expect to serve almost 8M travellers on our platform with a GMV in the range of €500M in 2022; and continue to grow GMV to €700M+ by 2025. More details of our growth strategy and our significant growth ambitions are available in our recent Capital Markets Day presentation on our corporate website.
