In addition, the company has developed tools to help refugees.

“We have all seen pictures of the unfolding humanitarian and refugee disaster in Ukraine. To help the growing number of refugees in the region, we are developing ways for businesses to report whether they are providing services to refugees. Starting today, hotel owners in Ukraine's neighboring countries can indicate in their business profile whether they offer free or discounted accommodation for refugees.
