Intercom is a next-gen CRM and communication product for web businesses—they find it hard to connect with their customers, resulting in abandoned trials, low upgrades, churn.

Intercom lets them:

1. identify users they need to reach out to,
2. research those users (social plus account info),
3. contact them (in-app or e-mail, automatically or manually),
4. track the relationship over time.

Invite-only beta, 550 active users who love it: "Intercom has changed the way we talk to our users."
