Under 80: engineering-heavy, no sales ops. Over 400: mature GTM with locked stack.

How to verify

LinkedIn company page: check employee count.

Two or more sdrs roles means building a team, not backfilling.

How to verify

Read JD for CTO, VP Eng, or data leader mentions.

Same ICP, completely different buying windows. Use this to rank your list.

Signal	What it means
3+ SDR/BDR roles posted in last 14 days	Building outbound function. Need prospecting tools, data, and sequences.
Head of Sales Dev or SDR Manager posted	Leadership hire means budget is approved. This person selects the tools.
Series B closed 3-14 months ago	Past post-raise setup, executing outbound growth plan. Tool evaluations peak.

High-priority: call this week

Example: Strong-fit account

Matches all filters, multiple signals firing

GTM hiring: recent3+ roles openNew sales leader

Multiple P1 signals firing. Building a sales team under new leadership. Reach the decision-maker within 48 hours while tool selection is active.

Low-priority: set a reminder

Example: Wait-and-watch account

1 role postedRecently funded

One signal, too early. Just raised, small team. Likely a backfill, not a build-out. Set a 90-day reminder and check back when hiring accelerates.
