Transaction Summary

  • In 2008, Essex Woodlands acquired a $20M stake in the publicly traded shares of ATS Medical.
  • The growth capital allowed management to invest in Sales & Marketing and pursue small tuck-in acquisitions. Sales ramped at ~20% per year and the Company turned profitable in 2008.

“Business of course is the allocation of human and capital resources to create customers; it’s really a very simple exercise but such a hard thing to execute well in practice. Essex understands the algorithm and importantly possesses the wisdom gained from experience to know when and how to partner with its companies. Whether solving problems or capitalizing on opportunity, I have seldom worked with nicer, smarter people in my career. Their collective experience and strong strategic sense is deep and broad and available at the asking, to which we called upon regularly as we built ATS Medical!”
