Internet of Things
Our engineering team specializes in building software and APIs for hardware products.
Custom OS, firmware, cloud APIs, pairing flows and companion apps for connected devices.
Highly available, always on
Our IoT software infrastructures are built to be highly available, fast, and reliable, powering award-winning devices and the user experiences that depend on them.
Our Process
We like to start new engagements with our Technical Blueprinting phase. We listen, research, test, and consolidate our plan into an architecture document that guides the build.
Our development process is agile, transparent, and collaborative, managed through lightweight weekly touchpoints, tight feedback loops, and waves of iteration.
As your product rolls out, we’re standing by, fixing bugs, tweaking codepaths, and shipping features in realtime, from mass production at the factory to your first customer ship, and beyond.
We’re friendly, transparent, communicative and hospitable, as it’s our best relationships that produce the most meaningful work.
Tools, not apps.
Light doesn’t have a massive deck of brand guidelines and product strategy, it has a philosophical starting point: build tools that enable people to live better, which all other decisions stem from.
For Light, minimal UX isn’t an aesthetic treatment, it’s a choice, rooted in ethics, that our team understands and implements innately and autonomously.
As trusted, long-term partners, our developers grew into holistic stewards of the entire Light III product roadmap. Our small team was trusted to make high-impact choices around architecture, tooling, and feature behavior without layers of overhead.

Take a deep dive
The LightOS is a minimalist smartphone operating system, designed to be used as little as possible.
Running on a Qualcomm Snapdragon with a custom rendering pipeline to power Light II’s beautiful E-ink screen, the LightOS is based on Android, and supports all mainstream smartphone functionalities such as Bluetooth, Wi-Fi, Contact Sync, and more.

Tools for Humanity
The founders of Nest wanted to build a smart food waste bin that could measurably cut household greenhouse gas emissions. We helped them go to market.

The Future of Food Waste
The Mill kitchen bin is an ingenious device that works to convert wasted household food into Food Grounds™ for chickens.
We began working with the Mill team when their bin was in prototype, working hand-in-hand from foundation to launch.
We started with a deep technical blueprint, thorough enough to deliver on time and on budget, loose enough to evolve as we learned the product alongside Mill.
We advised Mill on which technologies, frameworks, and development practices would make their e-commerce website, user intake flow, and Android and iOS apps a reality.

We strive to build thoughtful, human-centric products through an open and transparent approach to timelines and estimates.

From sketch to $500m acquisition
To kick off the project, Brynn, the founder of Mirror, shared this drawing of her vision for the product. This was the very first kernel of the idea for the Mirror, which went on to be acquired by lululemon for $500m.


Form Meets Function
The product’s unique physical form became a foundational consideration in shaping the interface experience. We designed the UI to complement the hardware’s distinct geometry, creating interactions that felt natural, intuitive, and deeply integrated with the device itself.

Bridging Device and Mobile
We designed the experience to move seamlessly between device and mobile, ensuring each touchpoint felt connected and intuitive. User journeys were carefully mapped to support smooth transitions, whether users were interacting on-screen or managing settings through their phone.
