Whether building a single-use device from scratch or scaling a line of smart products, with Mason it’s 20x faster and 10x less costly to build, deploy and scale. Digital transformation is a modern requirement but operating a hardware-dependent initiative is hard – thousands of hours and millions of dollars are at stake. The Mason Smart Device Platform is the only fully managed infrastructure for developing and delivering dedicated devices. It offers flexible usage-based pricing for fleets of devices and manages the underlying complexity of all associated backend services, making software delivery on a smart product line—whether it’s a tablet, wearable or new form factor—as simple as delivering software in the cloud. This frees innovators to focus on what matters: application development, feature specification and UX. Granular access to add, remove or lock down capabilities makes it possible for highly customized products to be built as envisioned. Mason offloads hardware investment risks and logistics, including inventory procurement, warehousing and supply chain management. With options like zero-touch provisioning, devices can work perfectly out of the box without end user intervention. Remote fleet management, troubleshooting and automated software updates by Mason ensure security and positive end user experiences. Organizations of all sizes rely on Mason to bring innovations and hundreds of use cases to market without reinventing the wheel.

  • Cash Flow Portal
    Cash Flow Portal (w2022)Active • 19 employees • Seattle, WA, USA
    Cash Flow Portal is an investment management platform for real estate. We launched 5 months ago, and we have 6-figure ARR, growing 50% month over month, with 300 syndicators and 3,000 investors. We’ve grown quickly because I am a syndicator myself. Having raised $20MM for my own deals, I know how painful it is to manually prepare Docusigns, send wire instructions and wrangle investors. I also happen to be friends with 2,000 other syndicators just like me needing a solution for managing their investors. I’m not just a syndicator. I spent most of my career as an engineering leader at Lyft, Twitter, and Amazon. $20K ARR per syndicator gives us a $2B TAM. Having achieved my own financial freedom through real estate investing, our mission is to serve all real estate investors and help them achieve financial freedom.
