About Us

We provide Entrepreneurial Stage Capital to fast-growing, recurring revenue-model, software-enabled companies which address healthcare business needs or supply chain inefficiencies. We focus on opportunities throughout the Mid-America.

We are often the lead institutional investor in a Series A round with check size from $1.5-3.0 million, but we also participate with smaller investments in earlier rounds in order to partner with Series A prospects, as well as participate in follow-on rounds when we’ve previously invested in an A round.

We have significant experience with entrepreneurial stage companies and know where we can add value by challenging, but not second-guessing management.
