Enrich and segment a target account list for personalized campaigns

<context>
I have an account list for an upcoming campaign but it needs enrichment before we can use it properly. Right now it's just company names — no firmographic depth, no contacts, no signals. I need to enrich every account with verified data, segment the list by firmographic profile, and identify the right contact per segment so the campaign message can be tailored to each group.

My account list:
- Paste your account list: [PASTE COMPANY NAMES OR DOMAINS — one per line]
- Campaign goal: [e.g. "Q3 outbound campaign targeting RevOps" / "product launch to mid-market SaaS"]
- Target persona: [e.g. "VP of Revenue Operations, Director of Sales Ops"]
- Seniority floor: [e.g. "Director and above"]
- Segmentation criteria: [e.g. "by company size" / "by funding stage" / "by tech stack" / "by industry" — or "suggest segments"]
- Campaign channel: [e.g. "email" / "paid social" / "direct outreach" / "all"]
</context>

<task>
1. For each account on the list, use Lusha to enrich with verified firmographic data:
   - Current headcount and headcount growth trend
   - Industry and sub-industry
   - Funding stage and most recent funding event
   - HQ location and regional offices
   - Tech stack (if available)
   - Revenue range (if available)

2. Check Lusha's signals layer per account for the last 30 days:
   - Funding event, exec hire in target function, headcount surge, M&A, tech stack change

3. Find the right contact per account matching the target persona:
   - Most senior verified contact in the target function
   - Verified work email and direct mobile
   - Flag any account with no verified contact at the required seniority level

4. Segment the enriched list based on the stated segmentation criteria:
   - If "suggest segments": analyse the enriched data and recommend 3–4 natural segments
     with a distinct message angle for each
   - For each segment: list the accounts, the shared firmographic profile,
     and a one-line message angle recommendation

5. Return:
   - Full enriched account table: company, headcount, industry, funding stage,
     tech stack, signal, verified contact
   - Segment breakdown: segment name, accounts in segment, shared profile, message angle
   - Any accounts with no verified contact — flag for manual research
   - Summary: X accounts enriched, X segments, X accounts needing contact research
</task>

<constraints>
- Only return Lusha-verified contact data. Don't fill gaps with guesses.
- If segmentation criteria is "suggest": base segments on the actual data returned, not assumptions.
- Message angle per segment must be specific — not "personalize the email" but what specific
  angle works for that firmographic profile.
- Flag missing contacts clearly — don't skip them silently.
</constraints>

The situation: A demand gen manager has a list of 8 company names for a Q3 RevOps campaign. No firmographic data, no contacts. Running enrichment and segmentation before briefing the copywriter.

Enriched account table

Suggested segments (segmentation criteria: “suggest segments”)

Segment A — Post-funding growth companies (2 accounts) Dunmore Analytics · Falcrest Tech Profile: Series A or B closed in last 30 days · 300–600 employees · active hiring Message angle: “You just closed a round — your RevOps stack needs to scale with the headcount. Here’s how teams at your stage handle the data quality problem before it breaks.”

Segment B — Scaling SaaS on HubSpot (3 accounts) Crestline Software · Ashford Platforms · Briarway SaaS Profile: 290–420 employees · HubSpot as CRM · Series A or Seed Message angle: “RevOps teams on HubSpot at your size hit the same wall — enrichment gaps slow SDR ramp. Here’s how to fix it natively.”

Segment C — Mid-market Salesforce shops (2 accounts) Greenway Cloud · Halcyon Data Profile: 470–580 employees · Salesforce as CRM · Series B Message angle: “At your scale, Salesforce data decays faster than the team can clean it. Here’s what mid-market RevOps teams do about it.”

Missing contacts — flag for research

Elmont Systems — only Director-level contact found in RevOps. Run the find the decision-maker prompt to find VP or above before activating.
