About – The Sisu Story


Marc Christenson and Russell Aldridge started Sisu Devices in a garage in 2010. Quite simply, we wanted to do what we love: create incredible electro-mechanical machines and build a company that would bless the lives of its customers and employees.

We have built great machines for companies large and small throughout the United States and around the world. Sisu team members bring creativity and a can-do attitude to the world of precision industrial robotics.

We are located in Austin, Texas.


In 2011, with three people in the company, Sisu moved to a nearby business complex to build “Pipe Dream” for Intel. We built a number of iconic projects there, including the National Instruments Semiconductor Test Head and Servo Tennis for Kollmorgen.


The owners of the machine shop which had produced parts for Sisu for the last three years were retiring. Sisu bought Double M. Machining and moved to the 5600 square foot facility on Royston Lane. This brought the much needed ability to fabricate parts internally.


Sisu broke ground in early 2016 for a 12,000 square foot expansion at the Royston Lane facility. Also included was a remodel of the existing 5600 square foot building and total site redevelopment. The project is scheduled for completion mid 2017.

Since those humble days in the garage, we have grown to employ incredibly talented people from Utah, Nebraska, Colorado, California, Oregon, Arizona, Idaho, Indiana, Canada, Alaska, Hawaii, Vietnam, the Virgin Islands, Liberia, Puerto Rico, and yes … the great state of Texas.

Our employees are machinists, assembly technicians, and engineers. Engineering disciplines include mechanical, electrical, software, and manufacturing.

The Sisu Name

Sisu is a Finnish word that doesn’t have a direct translation in English. It is a grim, gritty, white-knuckle form of courage where success is against the odds. It expresses itself in taking action and displaying resoluteness in the face of adversity.

Marc and Russ were pondering what to name their new business when they first learned about sisu while watching an episode of Top Gear. This courage to succeed against the odds — on behalf of ourselves and our customers — is precisely what sets Sisu Devices apart.
