    Isolated tools

    Hosts and managers relied on different apps for reservations, guest lists, and communication, creating errors and inconsistent hand-offs between teams.
    Ellipse

    Manual tracking

    Table turns and server rotations were tracked by hand, causing delays and uneven workloads that hurt the guest experience.
    Ellipse

    Limited personalization

    Guest notes and visit history weren’t available in real time, preventing staff from tailoring service to returning customers.
    Ellipse

    Operational delays

    Without live POS data, hosts had no visibility into order status or table readiness, resulting in longer wait times and lost revenue potential.
