Ep. 232: Fixing growth systems from the inside out
June 3, 2026
Ekaterina Gamsriegler, former Head of Growth and Marketing at MyGroove and longtime advisor across music, education and health apps, joins Apptivate to discuss why sustainable growth depends on systems rather than isolated wins. The conversation explores the nature of modern growth funnels, how creative strategy impacts retention and churn downstream, and why many teams optimize acquisition while misunderstanding activation and long-term value. Ekaterina and Taylor also discuss localization as a full-funnel growth lever, pricing strategy during high-intent seasonal periods, the realities of founder-led and offline growth channels, and how mapping the complete user journey can uncover hidden bottlenecks that data alone often misses.
Why does Ekaterina compare growth systems to a house of cards?
How do creative strategies affect retention and subscriber churn?
What mistakes do apps make during seasonal growth periods like Q5?
How should marketers evaluate long-term value instead of short-term ROAS?
Why can localization improve the entire growth funnel?
How did MyGroove grow paying subscribers 10x in one year?
What role should brand, PR, and offline channels play in app growth?
How should teams define activation properly?
What should marketers focus on during their first 90 days at a company?
How can apps balance credibility with accessibility for beginners?
