About Murphy AI
Founded in 2024 in Barcelona by Borja and Marc, Murphy AI was born to address a pressing real-world problem: recovering payments from defaulting clients. The idea stemmed from Borja's firsthand experience as a CFO struggling with inefficient debt collection processes in his previous ventures. Partnering with Marc, a passionate CTO eager to bring his own product vision to life, the duo set out on a mission. From the start, they shared an unwavering obsession: to solve a real problem and redefine how businesses recover unpaid debts.
