CANTON, Mich., June 1, 2026 – Innkeeper LLC, a leading manufacturer of custom-engineered test equipment, today proudly announced its 20th anniversary. Specializing in solutions that integrate machine control with data acquisition for fatigue, strength, and durability testing, Innkeeper has built a reputation for innovation and adaptability in the field. Its systems are engineered around state-of-the-art control strategies, including Continuous closed loop (PIDF), Discrete closed loop, and Open loop applications, ensuring precise and reliable results for a wide range of testing requirements.
Founded in 2006 by Kevin Kretschmann, Chief Executive Officer and Founder of Innkeeper LLC., the company draws its unique name from the founder’s heritage—“Innkeeper” is the English translation of “Kretschmann” from an old Eastern German dialect, reflecting both the company’s roots and the personal dedication behind its creation. “By and large, the first and most common question we get when meeting a new customer has nothing to do with technology, control theory, or data acquisition. It is this: ‘Why in the world are you named Innkeeper?’” shares Kretschmann.
At the heart of Innkeeper’s enduring success is its steadfast customer-centric approach. The company has thrived through two major economic downturns due to a singular focus on listening to customers’ needs, delivering on promises, and providing unwavering support. The Innkeeper team is committed to being accessible, responsive, and supportive—believing that true service means answering the phone and standing behind every solution delivered.
With expertise spanning Machine Controls Retrofits, Servo-Hydraulic Test Equipment, Electro-Mechanical Test Equipment, Pneumatic Test Equipment, and fully Custom Test Equipment Solutions, Innkeeper delivers new machine designs, control retrofit upgrades for existing machines, and standardized bedplate/tabletop test control systems. By operating at the critical intersection of machine control and data acquisition, Innkeeper supports essential physical testing processes for mechanical failure, function failure, and strict quality confirmation.
Over the years, the company has expanded its technical footprint well beyond the automotive and aerospace sectors to serve the biomedical, marine, rail, and electronics markets. The organization builds physical and software interfaces that help customers achieve reliable product validation.
“As I look back over the past twenty years, I’m reminded that true progress is forged not only in breakthrough technologies but in the relationships we build and the challenges we overcome together,” said Kretschmann. “Innkeeper was born from a vision to innovate in both product and service, and to stand by our customers no matter how complex their testing needs. Our legacy is one of resilience—adapting in times of uncertainty, thriving through adversity, and delivering trusted solutions that help shape industries around the world. The impact of our work is measured as much in the confidence we instill as in the data we deliver.”
The company addresses the moving target of customer specifications through highly adaptable hardware and software. Engineered systems like the modular InnControl (automated test and production control software) platform allow users to configure, calibrate, and execute reliable test sequences with ease. The integrated data acquisition functionality reduces the need for separate data collection and retrieval systems. This practical approach ensures that testing systems can be adapted for future changes in sensors, actuators, and test cycles.
“Innovation is at the core of our daily operations, and we remain heavily committed to pushing the boundaries of physical testing,” said Bill Pagels, Chief Operating Officer. “We are thoroughly prepared for the next 20 years. By focusing on adaptable designs and emerging technologies, we will ensure that we continue to deliver exceptional value, responsive support, and reliable results for our customers well into the future.”
