Frequently Asked Questions

Why build when Slack exists?

Build for niches Slack underserves: industries needing HIPAA compliance, teams wanting self-hosted, specific workflows, or budget-conscious orgs.

How do you compete with Slack free tier?

Dont compete on price. Compete on specific features, compliance, self-hosting, or industry specialization that Slack cant easily replicate.

Is real-time messaging hard to build?

WebSocket basics are straightforward. Scaling to millions of concurrent users is hard. For MVP, services like Ably or Pusher simplify real-time.
