Our technology startup faced a critical and potentially devastating dispute with a former co-founder over intellectual property rights and contractual obligations. We were referred to Marissa Tillem at Proskauer Rose, and it was the best decision we could have made. While her profile notes her recognition in Commercial Litigation, her on-the-ground skill was immediately apparent. Marissa expertly navigated the intricate contractual nuances and New York partnership law. She developed a strategic approach that was both assertive and pragmatic, clearly explaining every option and its potential outcome. Her professionalism and calm demeanor were invaluable during a stressful period. The matter was resolved favorably through a negotiated settlement that protected our core assets and allowed the business to move forward. Her foresight and meticulous preparation were instrumental in achieving this positive result.
