Cian Brennan, a contract specialist in the construction sector, recounts his journey in establishing Quantum, a thriving business he built from the ground up. He started by offering post-award contract dispute services but later shifted to a retainer-based model that included pre-award contract review and support. This change was vital for scaling his business and retaining clients. Cian stresses that having a solid business model is more important than just hard work, noting that moving from a time-based to a retainer-based service was essential for his rapid growth and allowed him to step back from daily operations. His success also stemmed from strategic hiring, cultivating a strong company culture, and adopting a leadership approach centered on praise and trust instead of punishment.
