What started as a simple vibe-coded portal to replace an outdated SaaS tool became one of the most impactful agents SaaStr has ever built. Meet QB1, SaaStr's AI VP of Customer Success, and the full story of how Amelia Lerutte, Chief AI Officer at SaaStr, built it, broke it, fixed it, and shipped it to production for over a hundred sponsors ahead of SaaStr Annual. In this session, Amelia and Jason Lemkin, Founder and CEO of SaaStr, cover: Why QB1 didn't start as an agent, and the exact moment it became one. How a 70% reduction in billable agency hours happened almost as a side effect of going to production. The before-and-after of customer onboarding, from generic newsletter-style emails to hyper-personalized, task-specific outreach sent to 100 customers in under 10 minutes. The full step-by-step breakdown of how to reverse-engineer QB1 for your own business, including the original spec, the evolved spec, and what changed between them. Why you should never load sensitive customer data directly into your vibe-coded agent, and how agent hopping works as a security layer. What actually breaks when you go to production, and how to catch it before your customers do. The real cost of running all of this, including why SaaStr hasn't hit its $200/month AI token cap across every app it's built. This isn't a theory session. The prompts are in the slides, the portal is live at saastrsponsors.com, and Amelia Lerutte is rebuilding the AI VP of Marketing live at SaaStrAIAnnual.com on Deploy Day, May 12th. If you have any gaps in your onboarding, retention, or customer follow-up process, and you know you do, this is where to start.
