Lennie Nuara is a co-founder of Flatiron Law Group. He is a nationally recognized authority on technology and internet law. Known for his high energy and unique blend of legal knowledge, technology expertise and skills, Lennie serves as trusted advisor to dozens of multinationals and smaller corporates, hospitals and healthcare providers, financial institutions, startups and venture firms across industries including, E-business, retail, hardware and software, communications and energy, frequently involving the development and deployment of breakthrough technologies. His unique insights inform the strategic guidance and counseling he provides to clients. He also advises on mergers & acquisitions, privacy, cyber security and compliance. He offers specialized expertise in the creation of dynamic workflows and incident recovery solutions to manage and mitigate risk exposures. Clients engage Lennie regularly as a special counsel or to manage complex litigation in areas requiring his unique skill set and knowledge. An experienced commercial litigator, Lennie has handled high-stakes disputes in involving IP infringement, engineering and construction, IT systems and Internet businesses, including the successful resolution of several multi-hundred-million dollar matters.

Lennie was a partner at several prominent law firms and served as the Chair of the Technology & Intellectual Property Practice of Thacher Proffitt & Wood, LLP, and was a partner in the Intellectual Property and Technology Practice at Greenberg Traurig, LLP. Lennie gained recognition as a “go to” technology expert and problem solver following the tragic destruction of the World Trade Center on September 11, 2001, home to Thacher Proffitt & Wood’s main office. Miraculously, no employees of the firm perished, but the destruction of the Twin Towers resulted in a complete loss of all of the firm’s technology infrastructure and backup systems. On that day, Lennie interrupted his practice of law and became the CIO of the firm for the following six months. He was responsible for all decisions for the interim survival and ultimate rebuilding of the firm’s technology infrastructure. The experience of losing everything, rebuilding everything from scratch, being the buyer instead of “representing the buyer” has given Lennie valuable insights that inform his practice today.

Prior to joining Flatiron, Lennie was COO and General Counsel for ICF Mercantile, where he managed the transformation from a distribution to manufacturing business in a new state of the art manufacturing, research and development center. While at ICF he was responsible for all aspects of business operations, legal and IT, including creating the financial and production models to support the financing for transition; negotiations of the lease, construction, engineering, and architectural services agreements; and on-site management of construction resulting in an on-time and on-budget startup.

Before ICF, he was the co-founder, President and COO of Tera Group and TeraExchange, where he developed and managed the strategic evolution of the first and only multi-asset, Central Limit Order Book and RFQ based Swap Execution Facility and multi-asset execution management system from inception into a Dodd Frank Act – CFTC regulated institutional exchange for cleared derivatives, equities, futures, fixed income and options markets. Derivatives assets include IRS, CDS, NDF, and the first regulated Bitcoin derivative based on the TeraBit Bitcoin Price Index. He managed fundraising, client/investor presentations and relationships, operations, legal, regulatory, financial, marketing, business development and technology development and implementation.
