Hapbee Manufacturing

Based on feedback from the C-Suite during our initial investor rounds and our Indiegogo campaign, it became evident that we needed to enhance our manufacturing process. Initially, due to stringent security requirements, the production time for a single device ranged between three to seven hours, involving Bluetooth capabilities and a custom Xamarin App.

To address this inefficiency, we implemented improvements using Microsoft Windows SDK, Microsoft .NET, and customized test and manufacturing hardware. These technological integrations significantly streamlined our manufacturing operations.

By December 2022, these strategic updates allowed us to reduce the manufacturing time dramatically to just 12 minutes per device, encompassing both programming and testing phases. This enhancement not only optimized our production process but also enabled us to meet the high-volume demands of our Indiegogo backers and investors more effectively.

This substantial reduction in manufacturing time significantly boosted our production capacity and operational efficiency, ensuring we could scale our output to meet investor expectations and market demands swiftly.
