We speak both languages.
In the technology world, hardware engineers and software developers rarely sit at the same table. The result? Disconnected systems, integration nightmares, and stalled projects. Letter 10 Group was founded in 2017 to fix that.
We are a Michigan-based collective of engineers, developers, and system architects. We believe that a mobile app is useless without a solid server, and a smart sensor is useless without intelligent code.
By housing Electrical Design, AI Development, and Managed IT under one roof, we eliminate the gap between "concept" and "functioning reality." Our clients stop paying integration tax: the time and money lost when three different vendors can't agree on an architecture.
Full-Stack Depth
From the circuit board to the cloud. We don't sub out the hardware or hand off the firmware. The same team that designs the PCB writes the embedded code and configures the Azure tenant it reports to.
Domain Credibility
We've worked in pharmaceutical GMP lines, defense-adjacent supply chains, healthcare systems, and consumer IoT products. Compliance and regulatory context isn't a footnote. It's in the design from day one.
Michigan-Based, Hands-On
Boots on the ground for Michigan clients. On-site installation, local support, and a team that understands Midwest manufacturing culture.
From business problem to functioning reality.
Discovery
We listen to the business problem, not just the technical symptoms. No solution pitch until we understand the constraint.
Architecture
We map hardware and software requirements together, not sequentially, not in silos.
Development
Agile sprints with regular demos. You see working output every two weeks, not at month six.
Deployment
On-site installation, cloud configuration, and cutover. Managed by the same team that built it.
Support
Long-term monitoring, maintenance, and updates. We stick around.
