Find verified US B2B contacts — emails, direct dials, and buyer intent for 5.9M+ American companies. 98% deliverability. No annual contract.
Your bounce rate is lying to you. When 1 in 4 emails you send to “verified” US contacts hard-bounces, that’s not bad luck — it’s bad data. The US B2B market has 5.9 million companies and tens of millions of decision-makers, but most contact databases are selling you a snapshot from 18 months ago and calling it current.
B2B contact data decays at 2.1% per month. That’s 22.5% of your database gone stale every single year. If you’re running outbound at scale in the US market, stale data isn’t an inconvenience — it’s a quota killer.
InboundLabs gives you 280M verified B2B contacts with 98% deliverability, including US decision-makers across every major industry, company size, and geography. No annual contracts. Start free.

What is B2B contact data?
B2B contact data is the structured set of information — business email addresses, direct dial phone numbers, job titles, company firmographics, and intent signals — used by sales teams to identify and reach decision-makers at target companies. High-quality B2B contact data is verified, current, and compliant with data privacy regulations.

The United States is the world’s largest B2B market. That scale creates opportunity — and complexity. Here’s what separates US-specific contact data from generic global databases:
There are approximately 5.9 million B2B companies operating in the US, ranging from Fortune 500 enterprises to sub-10-person startups. The SBA counts 36.2 million total small businesses. That means your ICP probably spans multiple company size bands, industries, and regions — and you need a database that covers all of them, not just the Fortune 1000.
US professionals change jobs faster than in most markets. LinkedIn data consistently shows US job tenure averaging under 3 years in tech and sales roles. When someone leaves, their work email is dead within 30 days. If your contact database refreshes quarterly (or annually, like some legacy vendors), you’re prospecting ghosts.
This is where most databases get embarrassing. A “phone number” in a B2B database could mean a company switchboard, an office line that routes to reception, or an actual direct dial to the decision-maker’s cell. Only one of those gets you a live conversation. InboundLabs verifies direct dials separately — not switchboard numbers dressed up as personal contacts.
