Ask Us Anything

A team communication app like Slack typically costs between $70,000 and $220,000 depending on features and complexity. An MVP with channels, messaging, and file sharing can start around $70,000, while a full-featured platform with threads, integrations, video huddles, and workflows ranges from $140,000 to $220,000.
