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-searchedge function (action: 'company_search'withlookalike_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 unknownmatch_count: How many lookalikes to find (default: 25, max: 100)preview_mode: Fetch 5 results first for quick validation
Execution
- Identify the seed company domain (ask user if unclear)
- Warn the user: "This search will cost ~2.5 AI Ark credits. Proceed?" (or offer preview first)
- Optionally run with
preview_mode: trueto show 5 results - On confirmation, call
ai-ark-searchwith seed domain(s) - 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
