Cover image for Brights developed a SaaS booking
Brights developed a SaaS booking platform for beauty service providers to replace manual scheduling through Instagram messages and phone calls. The platform allows customers to book appointments online, view real-time availability, and pay directly through the app. We built a seamless scheduling experience that simplifies appointment management for both clients and salon staff. The system also includes CRM features, notifications, payment integrations, and tools for managing specialists and services. A key focus was creating an intuitive user experience that reduces friction during booking and improves operational efficiency. The platform was designed to support scalability for growing salons and beauty businesses with multiple locations or specialists. Automated workflows helped reduce missed appointments and manual coordination efforts. By digitizing the entire booking process, the solution improved customer convenience while helping businesses streamline daily operations and increase booking conversions.

Cover image for The AVIS photo capture app
The AVIS photo capture app was built to standardize vehicle photography across rental, leasing, and return workflows. Brights developed a mobile solution that guides users through a structured photo-taking process to ensure consistent image quality and coverage. The app helps employees capture vehicle condition data faster while reducing human error during inspections. We implemented guided capture flows, validation logic, and seamless upload functionality to streamline documentation. The solution was designed to work efficiently in real-world conditions with different lighting, locations, and user experience levels. By automating and standardizing the process, the platform improved operational consistency across teams and locations. The app also simplified review and verification workflows for back-office operations. As a result, the client received a scalable mobile tool that accelerated inspections, improved documentation accuracy, and reduced manual processing effort.

The system was designed to scale across high volumes of conversations while maintaining fast response times and accurate answers. We also focused heavily on seamless integration with existing business workflows and CRM systems. The result was a scalable AI assistant that improved customer engagement, increased response efficiency, and provided 24/7 automated support.
