WHO YOU'LL WORK WITH 👨🏽🤝👨🏼
During 2020, Hostelworld pivoted from a more traditional functional CMO/CPO/CTO organisation to a ‘full ownership” growth team plus platform team model. More specifically, we established four growth teams to cover all consumer /hostel facing Apps and channels that reported into the CPO; and a separate CTO organisation that became responsible for supplying and maintaining common core services (such as inventory pricing, availability and checkout) via APIs to these four growth teams. Each of these four growth teams comprise resources that report into the CPO and dedicated resources drawn from the engineering function (developers, QA resources) and analytics function. Collectively, these four growth teams comprise ~ 50 headcount and are wholly accountable for their KPIs and roadmaps
We currently have four growth teams and four further central/support teams as follows;
- Paid performance team : responsible for growing and optimising our paid web channels, including (web) landing page optimisation
- Core team : responsible for our progressive web app (PWA Website), our organic web channels such as SEO, and more generally our core OTA funnel performance
- Mobile/Social team : responsible for our iOS and Android Apps, including paid and organic downloads, CRM strategy and more generally our social network and event management (LinkUps) platforms
- Supply team : responsible for all our hostel facing platforms and tools, supporting our two sided marketplace through collaboration with our customer facing teams and leading on our inventory, availability and rates position
- Product Design (Central) team : responsible for defining and implementing a uniform User Interface/Experience design language across our consumer and supplier facing Apps, consistent with our Mission and Brand
