We started using Criteo to optimize our adwords campaigns. Marketing people are fond of it. Before we were using just Google Apps, but we get better feedback by using Criteo. We focus on tools that help us convert our leads into actual rentals.
We use Salesforce for customer relationships. They are very expensive but we couldn’t be without them anymore. Everything is connected with Salesforce and we get notifications on our customers' favorite sailing areas, their budget, etc. This allows us to predict when they decide to make a rental. We collect data from every social network to find out who is most likely to make a purchase.
90% of our internal communication is by Slack. If I check them all, I know exactly what is happening in the office. I like Slack because it reduces the email load a lot. If you have a short question you can just Slack it. We use it only internally because the companies that work in the boating industry are mostly small family companies so people have never heard about Slack.
We have used Intercom before because the chat is very nice, but we realized that a ticketing system is better for us. We have many users and with Intercom you pay by the transaction, so it ends up being too expensive. With Zendesk, you pay monthly for unlimited transactions. They do not care how many visitors we have.
