This tool is even better than the most expensive customer support and CRM tools. I tried Zendesk and Hubspot. But this tool really solved all our problems. It is cross-platform, and it solved our support problem and feature requests directly. It was also customized to create custom interactions (e.g. reward redemption, following up sales lead) with customers and even allows collecting survey results. I should have bought 10 lifetimes licenses just in case :D Literally the best SAAS I tried so far, this guys will be a unicorn no doubt! All the best luck!
