B2B Prospect Lists, Built the Day You Order

Any industry, any state, any city. We build your database from scratch against your brief, verify the mail domain of every record, and deliver within 24–72 hours.

Measured hard bounce rate under 1%. Guaranteed under 2% — or we replace the batch. Up to 21 fields per record, including the company’s own H1 and page title for personalization.

You bought a lead list. Two weeks later you were still repairing your sender reputation.

The same file had been sold to five companies before you. The addresses were scraped two years ago, a chunk of those businesses have since changed domains or closed, and not one record tells you where it came from. You send the first sequence, hit a wall of bounces, and for the next month you can’t reliably reach even the good addresses on the list.
B2B contact data decays at roughly 2.1% per month. A list bought in January is materially wrong by December. Ours doesn’t exist until you order it.

Why cheap scrapers cost more than they save

A scraping tool costs a few dollars per thousand rows. Then you spend a day cleaning them, and you still don’t know which mailboxes exist.

Scraping tools compared with a b2b-leads.biz build, on the measures that decide whether a campaign lands.

Built so your sending stays clean.

Every domain is checked for a valid MX record before the file reaches you. Businesses with no website, a parked domain, or a domain that cannot receive mail are filtered out on our side.

Verified
Hard bounce rate measured under 1% across delivered batches. Guaranteed under 2%, counted on hard bounces within 30 days of delivery. Above that, we replace the batch.

Sourced
Every record comes from public business listings and the company’s own website. The file shows you the source domain and the final URL we read.

CAN-SPAM ready
You get verified business addresses. The sending obligations — physical address in the footer, working opt-out honored within 10 business days, truthful headers and subject lines — stay with you as the sender, which is where the law puts them.

We don’t resell 2023 data. Yours is built today.

Below is one record — exactly what you get across the whole file. Every field is collected on the day of your order.

Collected the day you order

The database doesn’t exist until you place the order. No resold files, no leftovers from someone else’s campaign.

Deduplicated

No duplicates by company name, phone, or domain. Multi-location chains collapse to one company record, so you contact each business once.

Delivery within 24 to 72 hours

You get an estimated record count before we start, not after you pay.

One record, twenty-one fields

This is a single row from a delivered file — every field collected on the day the order was placed. The whole database looks like this.

Empty cells are shown as they are. A record with no YouTube channel says so — we don’t pad the file to make the field count look better.

Twenty-one fields, and we’ll tell you which ones fill

Most vendors quote a field count and let you find the empty columns after you’ve paid. Here is what actually arrives in the file, and why.

Filled on every record

These aren’t estimates. A record that fails any of them never enters the file, so the column cannot be empty.

Review counts and ratings exist only where customers have left them. Social profiles run roughly 50–70%, higher in consumer-facing trades, lower in industrial niches.

You are billed per record with a verified email

Businesses without a working mail domain don’t reach your file and don’t reach your invoice. The trade-off is volume: in a narrow niche or a small state, the number of companies with a reachable address is finite. That’s why you get an estimated record count before we start — not after you pay.

Priced per record with a verified email

Not per row. Businesses without a working mail domain never reach your file, so they never reach your invoice either.

All tiers include the same 21 fields and the same bounce guarantee. Volume is the only variable.

Exclusive build

Add 100% and the dataset is built for you and never built again. Without it, the same brief may be filled for another buyer in your vertical.

Why it isn’t cheaper

B2B contact data decays at about 2.1% a month. A cheaper list is almost always an older list — you pay less and send to more dead mailboxes.

Larger and recurring

Above 5,000 records, or a standing monthly build, is quoted directly. Tell us the brief and the cadence.

Test 20 records from your own niche before you pay.

Fill in four lines. Within two hours you get a realistic estimate of how many companies exist in your niche, plus 20 complete records to inspect.
No spam. No sales calls.
