500K North American Executive Leads Needed

I am building a large-scale prospect list and need 500,000 fresh, accurate contacts pulled exclusively from Pitchbook. Every record has to come straight from that platform—no other sources are acceptable.

Scope
• Geography: America only
• Industries: investment, construction, food & groceries, plus CPA-related service firms
• Seniority: CEOs, Presidents, Vice Presidents, Directors, and key Accounts Payable decision-makers

Gsuite Leads Only

Data requirements
For each contact, I need at minimum: full name, verified corporate email, direct phone (if available), company name, industry classification, job title, company headquarters location, Pitchbook profile URL, and the date you exported the record.

Acceptance criteria
1. 500,000 total rows delivered in CSV or Excel
2. 100% of rows traceable to a unique Pitchbook profile link
3. Bounce rate below 5% on a random 1,000-email sample I will test
4. Duplicates removed before delivery

Please outline your approach to accessing Pitchbook at this scale, estimated turnaround time, and any tooling or enrichment techniques you plan to use.
