Katten has a long and distinguished history of advising successful entrepreneurs, the businesses they build and the people who invest in them. Our Entrepreneurial Ventures practice continues this legacy. We represent clients through all stages of the business life cycle: initial organization, seed capital, follow-on equity and debt financings, mergers and acquisitions, liquidity events and day-to-day matters along the way. We focus on high-growth companies ranging from early-stage businesses to well-known unicorns and leading multigenerational family businesses, with an emphasis on entrepreneurs developing technology-enabled innovations.

Seasoned advice at every stage

We provide clients with pragmatic advice and efficient solutions that complement their drive and creativity and help position them for the future. Extensive experience advising high-growth companies and the entrepreneurs driving them — whether on routine matters or transformational transactions — strengthens our insights.

We pride ourselves on understanding our clients' businesses and solving their problems. Our attorneys are often relied upon as outside general counsel; we are accustomed to answering the question "What would you do?" Clients benefit from our varied network of clients and other relationships, which include:

  • First-time and serial entrepreneurs
  • Family offices
  • High-net-worth investors
  • Institutional investors
  • Experienced executives
  • Owner-operated businesses.
