THE ALLIGATOR HOLDINGS STORY
Alligator Holdings, LLC was founded in 2018 by Mark G. Sellers, a respected Wisconsin business leader with more than forty years of experience in manufacturing and entrepreneurship. The company functions as an incubator, accelerator, and investor, providing capital, leadership, and operational support to help young or evolving companies grow.
Mark’s career began as a tool and die apprentice in Milwaukee before he founded MGS Manufacturing Group in 1982. Over the next three decades, MGS became a $200-million global plastics and tooling enterprise with operations in the U.S., Mexico, and Ireland. After selling MGS in 2016, Mark launched Alligator Holdings to build and support a new generation of companies grounded in technical excellence and ethical business practices.
Today, Mark continues to guide the organization as Chairman of the Board, helping each portfolio company align engineering, production, and strategy to achieve lasting results.

LIGHT SCIENCES & INNOVATION
LIGHT LINE MEDICAL
Platform technology leveraged in novel ways to prevent catheter-associated infections (CAI) from urinary, respiratory, and vascular/dialysis catheters. Without relying on drugs, chemicals, or harmful UV light, their PhotoDisinfection™ technology uses 405 nm visible light (i.e., violet/blue light that the naked eye can see). The light is delivered via a fiber optic cable placed inside a catheter. This disinfects and protects the inside and outside of catheters, killing microbes and preventing associated infections. Innovator in PhotoDisinfection™ technology to prevent catheter-associated infections.
STABILUX BIOSCIENCES INC
StabiLux’s dye technology is poised to unleash the next 50 years of bio-medical innovation. Stabilux has developed proprietary, high-brightness fluorophores (dyes) for biomedical applications. The result is NovoLux® High-Brightness Dyes™, which are 2X to 1,000X brighter than any commercial dye, increasing the detection sensitivity of multi-color flow cytometry. Our dyes can be used with existing equipment, allowing researchers to detect what was previously undetectable.
