First Resonance accelerates the speed and reliability of hardware development for companies manufacturing the next generation of hardware products. This includes electric airplanes, autonomous vehicles, robotics, and more. We are a group of software, hardware, and manufacturing engineers that are bringing the best of modern UX and data science to an industry that has been overly rigid in its innovation. We are removing the barriers preventing radical advancement by providing tools to manufacturing engineers and operators to move information more freely, collaborate with their teams more easily, and use the power of data to predict problems and provide insights that result in better hardware quality and delivery.

About First Resonance

We are building a Factory OS for next-generation hardware companies so that they can deliver hardware faster and more reliably.

Company Culture

WE ARE ALL OWNERS — including individual projects, features, and the customer experience. Because we are all engineers, and so are our users, we value tight feedback loops and building for technical people. Given that we are young, we are scrappy and constantly have to make good judgements about speed to implementing and ensuring we don't bring down a manufacturing line.
