The thrill of landing that first significant sale or subscription is unmatched. You know the one. The deal that made you feel like you'd finally broken through, where your hard work started to pay off. Oftentimes, it’s not even about the money: it’s the validation of your idea, your work, and your belief. Those early successes can provide the motivation to keep moving onward and upward. So I'd love to hear your stories. How did you land that first pivotal deal for your SaaS startup? Any golden tactics or happy accidents? Any lessons learned you'd like to share?
