Mobile.dev is on a mission to set the new standard for mobile development. Our remote-first team comes from leaders in the mobile industry such as Uber and Google, and we’re backed by top Silicon Valley VCs. Our CEO and co-founder Leland Takamine was Tech Lead of Uber’s Mobile Platform team where he built novel tooling to manage the challenges of modern mobile application development. At mobile.dev, our mission is to empower all companies to deliver high-quality mobile applications. Leading mobile companies have already integrated mobile.dev to leverage the benefits of our innovative platform. Today, companies are shipping new app versions to their users without understanding the potential impact on app quality. Solutions available today allow companies to detect problems in production, but this reactive approach leads to unhappy users and wasted engineering resources. Mobile.dev is building a platform to better manage mobile application quality and detect issues before new releases go out. The first company to truly bring a ‘shift left’ approach to market, we automatically identify and address problems at development time, keeping users happy and saving countless engineering hours.
