How in-app communities are becoming a growth engine

As user acquisition gets harder and attention gets scarcer, apps are under pressure to do more than just “stay top of mind.” Building real in-app communities is emerging as one of the most effective ways to drive retention, trust, and long-term value.

In this App Talk interview, Peggy Anne Salz speaks with Luigi Manrique, Account Executive at Stream, about how leading apps are architecting community features directly into their products — from social feeds and chat to moderation, analytics, and feedback loops that actually scale.

Luigi shares concrete examples from companies like Robinhood, Strava, and Nextdoor, unpacking what it takes to design community experiences that feel native, trustworthy, and performant — especially in regulated or high-trust categories like fintech. He also explains why execution, rollout strategy, and moderation matter just as much as the idea itself.

The conversation closes with a look ahead at monetization, community-driven stickiness, and why apps that delay investing in communication and social layers risk falling behind as engagement becomes the primary growth lever.
