Product School — product management Slack community

Product School’s Slack workspace has grown into one of the largest real-time PM communities, with over 100,000 members across 26 local channels.

The standout feature is regular Ask Me Anything sessions with product leaders from companies like Google, Meta, and Amazon. These AMAs provide direct access to senior practitioners who share how they approach roadmapping, stakeholder management, and team building in practice.

Channels are organized by geography and topic — career transitions, interview preparation, tools, and AI in product management. The community also serves as a funnel for Product School’s paid courses and certifications, but the Slack workspace itself is free and active on its own.

Best for PMs who want asynchronous, global networking with a strong emphasis on career development and learning from senior product leaders.
