Ai Ark Similarity Search

---
name: AI Ark Similarity Search
description: |
  Find lookalike companies based on a seed company profile using AI Ark's
  AI-powered similarity matching. Provide a company domain or name and get
  back companies with similar firmographic profiles ranked by similarity score.
  Use when a user says "find companies similar to", "lookalike companies",
  "find more like", "companies like Stripe", or wants to expand their target
  account list from a seed company or their best customer.
  This is AI Ark's unique differentiator — no Apollo equivalent exists.
  Each search costs ~2.5 credits. Accepts up to 5 seed domains.

# AI Ark Similarity Search

## Goal
Find companies similar to a seed company using AI Ark's AI-powered similarity matching engine.
This uses the `lookalikeDomains` parameter — AI Ark's unique differentiator with no Apollo equivalent.

## Credit Cost
Each similarity search costs **~2.5 credits** (uses the company search endpoint with `lookalikeDomains`).
Use `preview_mode: true` to fetch 5 results first (same cost) before running a full search.
Always warn the user before executing.

## Required Capabilities
- **AI Ark API**: Similarity search via `ai-ark-search` edge function (`action: 'company_search'` with `lookalike_domains`)

## Inputs
- `seed_company_domain`: Domain of the target company (preferred). Up to 5 domains for multi-seed matching.
  Examples: 'stripe.com', 'notion.so', 'hubspot.com', 'figma.com', 'salesforce.com'
- `seed_company_name`: Company name fallback if domain unknown
- `match_count`: How many lookalikes to find (default: 25, max: 100)
- `preview_mode`: Fetch 5 results first for quick validation

## Execution
1. Identify the seed company domain (ask user if unclear)
2. Warn the user: "This search will cost ~2.5 AI Ark credits. Proceed?" (or offer preview first)
3. Optionally run with `preview_mode: true` to show 5 results
4. On confirmation, call `ai-ark-search` with seed domain(s)
5. Present results as a table for review

## Output Contract
Return a table with columns:
- Company Name, Domain, Industry, Employee Count, Employee Range, Location, Description, Technologies, LinkedIn, Website

Show `total_count` to indicate how many lookalikes exist in the database.

## Key Differentiator
Uses AI Ark's `lookalikeDomains` parameter on the company search endpoint.
Accepts up to 5 seed domains or LinkedIn URLs. AI Ark matches by firmographic profile similarity
(industry, size, tech stack, growth signals) — not keyword matching.

## Common Patterns
- Seed from best customer -> find 100 lookalikes -> people search for VPs -> outbound
- Seed from closed-won deal -> lookalikes -> pipeline expansion
- Multi-seed: pass 3-5 top accounts as seeds -> find companies matching that ICP profile
