Automated Cellular Lock Box

  • Haimat
  • Challenge

    Haimat wanted to simplify apartment hunting by strengthening security and integrating connected hardware.

  • Solution

    A two-week sprint to define their concept and turn it into two fully-functioning prototypes with fleet-management web interface.

  • Results

    A battery-powered cellular device with integrated touch screen, locking mechanism, SMS authentication, and web back end.

Apartment hunting on lock. Based out of New York City, Haimat wanted to make apartment shopping easier for prospective tenants and property managers. Instead of showing apartments in person, managers would be able to temporarily authorize prospective tenant’s phone numbers, allowing them to access a property during a specific window. In two short weeks, we delivered two fully-functioning cellular prototypes — each featuring firmware and pre-certified modules that easily migrated from small to large batch manufacturing.

  • Sprints & Intensives Think Fast

    We knew Haimat needed to get their concept in front of stakeholders as quickly as possible. We devised an aggressive, two-week timeline that allowed for periodic check-ins with the Haimat team. Our extensive experience, paired with our understanding of their vision, allowed us to intuit Haimat’s needs and anticipate challenges.

  • A battery-powered cellularly-connected lockbox that Haimat could show off to investors and use to accelerate the manufacturing process.
  • Hardware Prototyping What are the Options?

    We wanted the Haimat team to be able to make informed decisions about the features we were developing. When it came to prototyping the hardware, we focused on a few key aspects. In the end, the Haimat team was able to decide whether they wanted things like a digital touchscreen, a cellular component, or a locking mechanism by watching each feature in action.

  • Hardware Prototyping A Flexible Foundation

    When developing the software, we focused on scalability — making sure that we were creating a platform that could flex as the concept evolved. By building towards a minimum viable product, we ensured that the software could support the hardware components without limiting Haimat’s vision.


We helped Haimat bring their concept for automating the house-hunting process to life. Over the course of a two-week sprint, we delivered two cellular prototypes and a fleet management tool that Haimat could show off to investors, and use to accelerate their path to production.
