TitletownTech is investing in a company that is developing new technology to be used in environmental monitoring, biomanufacturing and human health.

TitletownTech is a joint venture between the Green Bay Packers and Microsoft.

The latest investment is in Chicago-based Stemloop. The money from TitletownTech will allow Stemloop to commercially launch a product people can use to test their water for lead.

"We're delighted to announce our investment in Stemloop," TitletownTech managing director Jill Enos said in a news release. "Stemloop's cell-free biosensor technology has exciting applications across a variety of industries and reflects our commitment to finding innovative solutions to meaningful problems."

"We're thrilled to receive this support from TitletownTech to continue expanding our operations," Stemloop founder and CEO Khalid Alam said in a news release. "Information is at the heart of solving the lead-in-water crisis, and by delivering accurate information at scale, Stemloop’s product provides critical answers. That's what our biosensor platform is all about -- utilizing nature’s sensing superpowers to respond to hard-to-detect challenges."
