About Smart Host

Smart Host provides a CRM and marketing automation system for independent and mid-market hotels. The platform uses machine learning and data segmentation to enable hotels to systematize guest interactions, automate targeted campaigns, and drive bookings directly rather than through OTA intermediaries. Founded in Berlin in 2016, the company operates a small, Berlin-based team focused on backend infrastructure, cloud operations, and product development. The product surface spans guest onboarding, campaign planning, third-party API integrations, and core hospitality workflows.
