Our vision is to be the world's leading social travel platform.

We are on a mission to help travellers find their people and create unforgettable moments together. Connections matter as much as destinations, and we are building a global ecosystem to enable them.

Since the launch of our social network in the hostelling category in 2022, Hostelworld has experienced transformational growth. We have successfully welcomed over 2.6 million social members to our platform, proving the strong demand for connection in travel. This vibrant community is not just booking trips; they are actively engaging, co-creating, and becoming our most powerful brand advocates. The platform is rich with user-generated content, including a rapidly growing volume of customer testimonials and authentic travel stories that provide powerful social proof.

The growth in engagement is remarkable: the number of messages sent between travellers has grown significantly faster than the number of trips booked by social members, demonstrating the deep social utility of our platform. This momentum is reflected in our robust financial health, underscored by a strong balance sheet powered by an asset-light, cash-generative business model.

We are not just another Online Travel Agent (OTA); we have created a new category of travel altogether: Social Travel. Our singular focus on helping travellers find people to hang out with is the foundation of our strategy. It has allowed us to build a powerful and defensible market position, which attracts highly valuable customers and shifts more of our business onto our mobile-native apps.

While our app and social features create a sticky user experience, our true competitive moat stems from the incredibly rich, proprietary data set generated by our social network. As our community grows, so does the value of this data, creating a compounding network effect that is nearly impossible to replicate. This "social flywheel" allows us to understand traveller behaviour, predict needs, and personalise experiences in ways that generalist OTAs cannot match. It is the engine that will power our long-term, differentiated growth and solidify our position as the sole player in the Social Travel category we created.

At our Capital Markets Day in April 2025, we unveiled our ambitious strategy to build on our success and realise our vision over the next three years. This strategy is organised around five key themes:

• Strengthening the Core OTA Platform: We will continue to enhance our core booking engine, ensuring a seamless and efficient experience for our customers and hostel partners, further solidifying our position as the leading platform for hostel discovery and booking.

• Building 'Pre-Booking' Social Features: We are developing innovative features like 'Travel Plans', designed to engage users much earlier in their travel journey. These features will accelerate the creation of social profiles and drive app downloads, fuelling our social flywheel before a single bed is booked.

• Leveraging AI for an Enhanced Social Experience: We will embed AI into our pre- and post-booking features to deliver unparalleled personalisation and value. This includes AI-powered recommendations for people to meet, places to go, and things to do, making our social network an indispensable travel companion.

• Expanding our Addressable Market: We will expand our reach and product portfolio through targeted partnerships and M&A. This will allow us to cater to a broader segment of the youth travel market and integrate new, complementary services into our social travel ecosystem.

• Building New Revenue Streams: Our social network is more than an engagement tool; it is a new platform for monetisation. We will develop new revenue streams directly from our social features, creating value for our users and our business in ways that traditional OTAs cannot.

Our Culture

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.
