Punch Through is a product development firm that specializes in the evolving world of connected product development. Building a smart-phone or IoT product requires knowledge of multiple systems, specifications, protocols, and operating systems. By understanding the whole system, we are able to create products that are reliable and dependable.

Building connected products since 2009

Building a smartphone-connected device requires expertise in multiple domains. Our team has expertise in every discipline to ensure your product is designed with the entire system in mind.

Bluetooth Low Energy Experts

We have been building BLE products since 2011. Our team has an intimate knowledge of the Bluetooth specification and everything required to build, test, and certify a BLE device. We follow changing specifications, components, stacks, and smart-phone APIs to keep your product up to date and future-proof.

LightBlue Explorer

Trusted by Over a Half Million Developers

When the first BLE-enabled iPhone was released, we noticed that there was no easy way to debug BLE devices. We created LightBlue Explorer for ourselves and released it for free to the community. Today it has been downloaded over a half million times.

Selected Work

Our clients range from Fortune 500 companies to stealth startups. We help guide our customers decision making on the process of developing a connected product, including systems design and component selection, firmware and software development, and integration with a manufacturer.
