Legato
Legato provides a lightweight operating system and connected audio stack that lets speaker manufacturers build WiFi-enabled, smart home-compatible products on affordable microcontrollers instead of expensive processors. Built on Zephyr, the platform covers the full connected audio spectrum from Bluetooth speakers to whole-home systems while remaining hardware-agnostic and free of ecosystem lock-in. This approach lowers BOM costs and reduces exposure to memory chip market volatility.

Problem
Speaker manufacturers face high bill-of-materials costs and technical complexity when building connected audio products, often forced to use power-hungry processors and navigate fragmented smart home protocols. Closed ecosystems from dominant tech players further erode brand independence, while poor software infrastructure and planned obsolescence undermine product longevity and user experience.
Solution
Legato provides a unified, open connected audio stack comprising a lightweight operating system, backend platform, and APIs that run on affordable microcontrollers rather than expensive CPUs. Built on Zephyr, LegatoOS covers the full connected audio spectrum—from Bluetooth speakers upgraded to WiFi, to whole-home audio systems, professional audio, wireless headphones, and smart home-integrated devices. The platform is hardware-agnostic, allowing manufacturers to bring their own components while ensuring cross-brand, cross-room, and cross-ecosystem interoperability. By simplifying firmware development and reducing BOM costs, Legato enables speaker makers to focus on acoustic craftsmanship and product design rather than software infrastructure.
Target Audience
Primary customers are consumer audio hardware manufacturers and speaker brands seeking to build connected, WiFi-enabled, and smart home-compatible products without the cost and complexity of Linux-based systems or proprietary ecosystem dependencies.
