STAMFORD, Conn., January 21, 2025 /PRNewswire/ — Gainline Capital Partners (“Gainline”) announced today that it has acquired M&M International (“M&M”), a leading manufacturer of precision-engineered stainless-steel tubing, primarily for the  medical device end market. M&M is headquartered in South Plainfield, NJ. 

“We are excited to build on M&M’s 30-year track record of supplying customers with high-quality products,” said Allan  Weinstein, Managing Partner at Gainline. “M&M is well positioned for accelerated organic growth and we plan to pursue  strategic add-on acquisitions to further advance its position in the market.”  

In conjunction with the acquisition, Jeff Robertson was appointed as Chief Executive Officer. Robertson is an experienced  leader in the medical device manufacturing industry and was most recently the Chief Operating Officer of Solesis. Joining  Robertson are Ed Graf as Chief Financial Officer, and Chris Pleibel as Chief Commercial Officer. “Jeff, Ed, and Chris bring a  wealth of experience and proven track records of scaling businesses,” said Rob Dellinger, Principal at Gainline. “We are thrilled  

to partner with them in the next stage of M&M’s growth.”  

M&M is a leading producer of 304 and 316-grade stainless steel small-diameter tubing for medical devices and other high  precision applications. M&M also recently launched its 17-7 stainless steel product offering, further expanding its market  position. “We are pleased to introduce 17-7 as part of our product portfolio,” said Robertson. “This expansion reinforces our  commitment to providing high-quality, specialized solutions that address the evolving needs of our customers. By broadening  our capabilities, we are positioned as an even stronger partner in supporting their critical applications.”
