What is a Segment?

A Segment is a target market group defined by shared characteristics — industry vertical, company size, geography, technical maturity, or business model. Segments go beyond simple firmographic filters. They include segment-specific messaging guidance, priorities, and approaches that agents use to tailor outreach for each market. For example, your “Enterprise Healthcare” segment might emphasize compliance and data security, while your “Mid-market SaaS” segment leads with speed-to-value and integrations. Agents read these differences and adjust their output accordingly, so the same Sequence Agent produces different messaging for a hospital system than for a Series B startup. Without segments, agents treat every prospect the same. With them, your outreach reflects the specific language, priorities, and buying patterns of each market you serve.

How Segments connect to other entities

  • Use Cases — which problems are most common in this segment
  • Playbooks — which sales strategies target this segment
  • Buying Triggers — which signals are most common in this segment
  • Companies (via analytics) — companies automatically linked to segments based on fit scoring
When an agent qualifies a company, it determines which segment the company belongs to. That segment informs which playbook activates, which use cases to emphasize, and how to position the product.
