Recent Transactions


Sullivan lawyers use sound business judgment to counsel emerging companies on a full range of business and legal issues. We balance business needs and legal realities to help growing companies thrive. We know that our clients are gauging opportunities and confronting challenges and seek our assistance in connection with protecting valuable intellectual property, securing equity and debt financing, negotiating technology licenses and joint ventures, mergers and acquisitions, crafting tax and deferred compensation strategies, resolving employment issues and responding to the threat of litigation. We understand the opportunities our clients need to take advantage of and provide quality, cost-effective solutions that help emerging companies cope with the human and financial challenges of rapid growth.

We represent regional, national and international venture capital firms and other investors that invest in early-stage companies across a range of industries, most notably in software, digital health, blockchain, fintech, communications, therapeutics, medical devices and energy sectors. We help venture capital investment professionals deal with the many contingencies that arise in transactions such as portfolio investments, liquidity events, corporate governance and compliance matters, intellectual property and other due diligence-review services. We also work with venture capital firms on fund formation and fund-raising efforts, and regularly advise institutions making investments in venture capital funds.

A key strength is our ability to facilitate introductions between investors and entrepreneurs and emerging companies, particularly in technology sector companies located in Ireland and Israel.
