The free sample

Don’t take our word for it. Take 10 rows.

The fastest way to judge a list is to check one. Your first 10 rows are free, built to your brief, not pulled from a demo file. Yours to keep either way.

You get 10 rows, or as many as your market honestly holds. We state the real count before we start, either way.

  • You name the niche, the geography, and the must-haves. Two minutes, in writing.
  • We build 10 rows to that brief, with the same checks as a paid list.
  • Delivered within one business day as .xlsx + .csv. Keep it and use it, whether or not you order.

Came from our email? Your sample is already built. Reply to that email and the full file is yours. The claim form builds a fresh sample, or one for a different niche.

The problem

The research is the bottleneck.

“Building a list eats a day we could bill.”

Built for you, business by business. Zero research hours for your team. The list lands ready to send.

“Bought lists are stale, scraped, and bounce.”

Researched fresh for your brief, checked before delivery. Rows that fail the checks are replaced free.

“Databases give us a country, not our towns.”

Built to your niche and your market, right down to the neighborhoods you serve.

“Generic rows don’t fit the clients we actually want.”

Your criteria on every row: category, services offered, rating, review count, a match note for your brief, and a named contact where one is published.

“We can’t tell if a list is any good before paying.”

You can here. The first 10 rows are free, built to your brief. Judge those first.

How it works

Four steps, all in writing.

  1. Request your sample

    Tell us the niche, the geography, and your must-haves. One short email, two minutes. No call, ever. Send us your current client list and we’ll exclude those businesses.

  2. We research

    Within one business day, we find and check every business one by one against public sources. Duplicates and dead ends come out.

  3. Check your 10 rows

    The sample lands by email as a spreadsheet. Verify any row yourself against its linked source. Keep it either way.

  4. Order the full list

    When you’re ready, order below. Same brief, 50 or 100 rows, same checks, in your inbox in 48 hours.

What we don’t do: no calls, no subscription, no resold lists. Everything happens in writing. No meeting that should have been a spreadsheet.

What you get

What’s in every list.

a.Business

Business name, website, category, city and state, confirmed live when we checked it.

b.Address & phone

Street address and main phone. As the business publishes them, not as a database last scraped them.

c.Named contact

A named contact and their role, where the business publishes one. If it publishes none, the row says so.

d.Email or phone

A verified published email or phone on every row. The email comes with the page it appears on linked in the row. If a business publishes no email, the row carries its published phone and says so. A row with neither never ships.

e.Match note

The fact that makes the business fit your criteria. Not a category guess: the actual thing we saw.

f.Source & date

The source URL behind the row, and the date we checked it. Every row can be retraced.

Also in every file: a one-page Column Dictionary defining every field and flag. Files arrive as .xlsx + .csv, with CRM-import-ready columns.

In the 100-row build, also: First-Line Openers (one specific observation per business, ready to open a cold email), a Bounce-Safe re-verification pass with risky rows flagged in their own tab, and a Second-Geography Snapshot: counts only, for one neighboring area you name.

Our standard

What we never do

  • ✕Guess an email from a name pattern
  • ✕Copy from an unverified database
  • ✕Mark a row “verified” that wasn’t checked

If a business publishes no email, it ships only with a verified published phone, flagged in the row. With neither, it never ships.
Honest blanks beat confident fiction.

Separate track · List cleanup

Already have a list?

Send your existing list or CRM export, up to 1,000 rows. We dedupe it, check what’s still live, flag dead and closed businesses with the reason (never silently deleted), fill the fields we can confirm from public sources, and hand it back clean in 48 hours, every change logged.

$199

Per list, up to 1,000 rows · 48 hours

Order list cleanup · $199

Returning clients can move to monthly refresh and ongoing build plans. Ask after your first order and we’ll lay out the options.

The guarantee

The Replacement Guarantee

If a row fails the checks on this page, we make it right:

  • Replaced free within 14 days. A closed business, one that doesn’t match your brief, a contact or email we recorded as published that isn’t, a duplicate. A hard bounce counts as a failure too: an address delivered exactly as the business published it that comes back undeliverable inside those 14 days is replaced free. Reply to the delivery email within 14 days and the row is replaced free. If no replacement can be found, the row is credited against your next list.
  • More than 1 in 10 rows fails? Then the order is on us: a full rebuild of the order, or a refund. Your choice.

To claim, email hello@prospectrowresearch.xyz within 14 days with the bounce notice or your sending platform’s bounce report naming the address. Full detail in the Terms.

We guarantee the data against your brief and our checklist. We can’t guarantee replies, meetings, or clients. No honest list can.

FAQ

Straight answers.

Is this AI or human?

The research, building, and checking are done by an AI system. A human owns the business and is accountable for the work. You set the criteria in your brief, and every row ties to a public source you can check. What public sources can’t confirm, we flag instead of guessing. It is disclosed here and in every email.

Where does the data come from? Is it legal to use?

Public sources only: the businesses’ own websites, public directories like Yelp, BBB, and chamber listings, and public registries. Nothing bought, nothing from behind a login, nothing private. Every row carries its source URL and check date, so you can retrace it. These are facts businesses publish so customers can reach them.

How accurate is it, really?

“Verified” means a checklist. The business is live and matches your brief. Any named contact is published with that role. Any email is copied from the page the business publishes it on. That page is linked in the row. We won’t quote an accuracy percentage; nobody honest can. The free sample lets you check the method, and the Replacement Guarantee backs every row.

Why not just use Apollo or Clay?

Tools like Apollo and Clay charge per seat, every month, and hand you a raw export: pattern-guessed emails, records of mixed age, and hours of cleaning still ahead of you before the file is safe to send. Prospect Row Research is the finished version of that job. One fixed price, no subscription. Every row researched and checked one by one from public sources. Emails are copied only from pages the business itself publishes, never guessed from a name pattern, and a source link rides on every row so you can check any of them yourself.

What if rows bounce or don’t fit?

Reply to the delivery email within 14 days. Failing rows are replaced free: a closed business, a wrong fit, an email that isn’t actually published, a duplicate, or an address that hard bounces even though we copied it exactly as the business published it. No replacement? Credited against your next list. More than 1 in 10 rows fails and you choose: rebuild the order, or refund. Replies and clients are never ours to promise.

How fast, exactly?

Samples land within one business day of a confirmed brief. Paid lists land within 48 hours of payment. You give your criteria before you pay, on the order page, so the 48 hours start the moment your payment lands. We take on 6 list builds a week. If the week’s slots are full, you hear your start date before you pay, never after.

Why no calls?

Working in writing only is how a hand-checked 100-row list costs $249 instead of research-agency rates. Brief, questions, sample, delivery: all in writing. Everything we promise sits in the thread, not in a call you have to remember.

What format do I get?

An .xlsx and a .csv, same columns: business, contact, published email or phone, fit details, source links, check dates. Plus a one-page Column Dictionary defining every field and flag. Columns are CRM-import-ready, so the file works the day it lands.

Can you build for my niche and city?

Probably, and the test is free. Tell us the target in writing. If we can’t verify it from public sources, we say so instead of selling you a list we can’t stand behind. If your market is too small to hold 50 verified businesses, you hear that before you pay.

Will you sell my list to someone else?

No. Every list is commissioned and built to one client’s criteria, and it is never resold. Your brief and your files stay yours.

What if I already have a list?

Then list cleanup is the offer: send your list or CRM export (up to 1,000 rows) and we dedupe it, check what is still live, flag dead and closed businesses with the reason, fill the fields we can confirm, and hand it back clean in 48 hours. $199, separate from the list builds.

No card, no call · Sample delivered within one business day · Yours to keep either way
