DornerWorks Ltd.

What DornerWorks Ltd. does

DornerWorks, Ltd. is a privately held electronics engineering services and proprietary intellectual property (IP) company headquartered at 3445 Lake Eastbrook Blvd SE, Grand Rapids, Michigan, founded in 2000 by David Dorner. The firm employs more than 80 engineers (firmographic range 101–250 total staff) and designs embedded systems for aerospace and defense, automotive, medical, and consumer electronics customers. Disclosed engagements include Traeger Grills (pellet-grill controller), Dexter Laundry (commercial laundry electronics platform), and an unnamed office-furniture manufacturer building a hotel-style reservation system on a Renesas RX631 microcontroller; the bulk of its defense and aerospace work is referenced through anonymous case-study material aligned to FACE, SOSA, and DO-178 standards rather than named prime contractors.

The company's core technology stack is built around embedded virtualization using the seL4 formally verified microkernel and the Xen-based Virtuosity hypervisor, paired with a deterministic networking portfolio that includes patented AVB IP and Time-Sensitive Networking (TSN) FPGA IP, plus space-grade Space Switch IP qualified to NASA radiation-tolerance standards for Microchip RTG4 and PolarFire FPGAs. Productized assets include the VM Composer tool for orchestrating virtual machines on AMD/Xilinx platforms and the MAPS Conformance IP for aerospace/defense standards verification. DornerWorks holds ISO 9001, AS9100, and ISO 13485 quality certifications (extending into 2028), and its Virtuosity hypervisor is certified to the Open Group FACE Technical Standard for military aerospace interoperability — credentialing that materially narrows the field of competing suppliers.

DornerWorks monetizes through three revenue streams: project-based custom engineering services, licensing of pre-built IP blocks (VM Composer, TSN/AVB IP, MAPS, Space Switch IP), and SuperchargedIP pre-configured networking/security IP bundles. Go-to-market is a direct enterprise field-sales motion augmented by strategic technology-vendor channels with Wind River (TSN integration with Helix Virtualization Platform and VxWorks), AMD/Xilinx (FPGA platform IP on Zynq, Zynq UltraScale+ MPSoC, Versal, Kria SOM), and Microchip (space-grade FPGAs). Leadership includes founder/owner David Dorner, President Shawn Isenhoff (15-year tenure), VP Sales & Marketing Lance Hilbelink, HR Manager Sara Parmeter, and Technology Strategy Leader / Chief IoT Engineer Greg Nowak. Talent is sourced through a co-op program with Grand Valley State University extended to Calvin University, Western Michigan University, Michigan Technological University, and Trine University, and the firm maintains an event-led presence at GVSETS, DeviceTalks Boston, and GR Tech Week.
