"There’s no magic bullet in marketing—just daily experimentation, measurement, and iteration." In this episode of Growth Talks, Michael Kaminsky, Co-founder of Recast, joins host Krystina Rubino to explore how marketers can rethink the way they measure success. Drawing from his early days at Harry’s, Michael shares how managing a lean media budget sparked his deep dive into media mix modeling and experimentation. He offers insights on how marketers can adopt a product mindset—treating measurement as an iterative process, not a final answer. Learn how ongoing optimization, directional data, and adaptive systems can help brands stretch their budgets, make smarter decisions, and scale effectively across channels. 🗝️ Key Takeaways: Embrace uncertainty. No model is perfect—but that’s not the goal. Structured experimentation brings clarity, reveals customer insights, and drives better decisions over time. Last-click attribution is limiting. It favors bottom-of-funnel tactics and short-term wins, while overlooking the long-term impact of brand-building and upper-funnel influence. Media mix modeling is evolving. Smart marketers are moving beyond slow, outdated models—adopting faster, real-time approaches that align more with consumer behavior. Stop overcomplicating measurement. You don’t need perfect data to move forward. Simple directional signals are often enough to guide strategic, timely decisions. Think like a product team. Continuous optimization and experimentation should be built into every marketing plan to stay agile and drive consistent growth. ⏰ Timestamps 00:10 - Intro to Michael Kaminsky 03:26 - From Harry’s to Recast: Why measurement needed a reset 07:21 - The blind spots of last-click attribution 14:34 - Why traditional media mix models fail modern marketers 18:38 - How brands can balance digital and offline measurement 23:37 - The importance of causal inference in marketing analytics 35:24 - The dangers of over-relying on data without strategic intuition 45:27 - Common mistakes brands make in cross-channel measurement 50:46 - The future of marketing measurement and why agility matters 55:46 - How to build a marketing strategy that adapts and scales   🔗Mentioned in this episode: Recast: https://getrecast.com/ Harry’s: https://www.harrys.com/ Away: https://www.awaytravel.com/ Mockingbird: https://hellomockingbird.com/ Rocket Money: https://www.rocketmoney.com/ 👍Did you enjoy this video?
