About Castly

Castly is profile activation infrastructure for dating products. It helps product and growth teams turn sparse photos and rough prompts into distinctive, complete profiles in about 60 seconds.

The platform combines a casting API, embedded onboarding widget, re-engagement nudges, and a partner dashboard. Every recommendation remains editable, openers are never auto-sent, and partners can measure profile completion and reply-rate lift against a control group.

Our goal is straightforward: reduce onboarding friction without taking agency away from the people creating their profiles.
