Medium-Business Lead Lists

I need a fresh, accurate list of medium-sized companies that match my ideal customer profile so I can roll out a cold-email and cold-call campaign right away. The list has to include verifiable decision-maker details—name, role, direct email, phone, company website, industry, headcount or revenue band, and the source you used (LinkedIn Sales Navigator, Apollo, ZoomInfo, Crunchbase, etc.).

Quality is more important than volume: every contact must be current, reachable and sit within a company large enough to fit the “medium-sized” bracket. Bounce-free emails and direct lines will be checked before I release final approval.

I’m moving quickly, so please tell me how many clean leads you can deliver, the tools you’ll rely on, and attach examples of similar lead lists you’ve built in the past. I’d like the first batch in my inbox ASAP, with the full file delivered in CSV or Google Sheet format.
