What drives real product growth—launching new features, or helping existing ones land? In this episode of The Effortless Podcast, Dheeraj Pandey and Amit Prakash sit down with Ken Rudin, former Head of Growth at Google, Facebook, Zynga, and ThoughtSpot, to unpack 15 years of lessons at the intersection of analytics and product. Ken shares the story of how a simple nudge doubled Google Search engagement, why retention curves are the truest measure of product–market fit, and how startups should think about growth before and after finding PMF. Along the way, he introduces frameworks like ARIA (Analyze, Reduce, Introduce, Assist) and MUD (Meaningful, Unique, Defensible) to help founders systematize growth instead of chasing hacks. From cross-selling in corner-store SaaS to the surprising power of changing a Google Ads hyphen into a vertical bar, this conversation shows why growth is less about tricks and more about rigorous, creative experimentation.
