RETENTION THAT PAYS FOR ITSELF

Grow loyalty, engagement, and lifetime value.

About Us

OUR PHILOSOPHY

OUR STORY

Castle & Rook was created to solve a common problem: brands invest heavily in acquisition, but rarely give lifecycle and CRM the strategy, structure, and attention needed to make retention truly profitable. We built our agency around fixing that.

Instead of surface-level tactics, we focus on the systems behind sustainable growth. Lifecycle mapping, CRM optimization, segmentation, cross-channel orchestration, and communication design that makes every touchpoint work harder. Today, we serve as a retention partner for brands that want deeper customer relationships and revenue that compounds over time.

OUR MISSION

Our mission is to make retention a strategic advantage for every brand we work with. That means building full-funnel lifecycle programs, optimizing CRM platforms, and running email, SMS, push, and in-app communications that consistently engage your customers at every stage of their journey.

Through clear strategy, thoughtful execution, and ongoing optimization, we help brands create retention systems that increase loyalty, lift LTV, and pay for themselves many times over.
