BeSpoke vs other providers
Your list is researched from live sources, never pulled from one provider's database, and every record carries a public source link that shows where it was found. A researcher reads each of those live sources at the moment your file is built.
Direct emails
Reaches her own company-domain mailbox, not a shared info@ inbox.
Direct dials and mobiles
Rings her desk or her cell, not the front office switchboard.
Every record keeps its public source link, so you confirm freshness on the origin page instead of taking it on faith. Gain varies by brief. If a ready-made list already covers your whole brief, that is the cheaper tool and we say so.
Your current list was built by a vendor type you never thought to check.

BeSpoke by BookYourData
Read at build time
BeSpoke reads every source live the moment your file is built.
A single endpoint sits on one fixed database, so every vendor tapping it receives identical records, and an export that quick is effortless to duplicate, which is how the same contacts get copied from file to file. Volume runs short for the same reason: a database hands back only what one company collected. BeSpoke reads live sources across the web as your file is assembled, so contacts who switched roles after any stored pull, and people the single endpoint never had at all, surface as the extra direct emails and direct dials in your build.
The BookYourData track record behind BeSpoke

built by hand, verified live, a public source on every record
verified reviews


















A database holds what is already public and structured, so it gives you the contacts everyone else already reaches. The buyers who matter most to you never showed up in the database, and waiting does not put them there. They are too new, too niche, or outside the standard job-title filters. A person has to go find them. Either your team finds them, or ours does.
BeSpoke is a private list building service that researches and hand-builds your contact list to a written brief when the audience you need does not exist in any database.
Custom list building is the common name for exactly that: a list built to your brief, not to criteria someone else chose before you asked. In practice that means every BeSpoke build starts with a free 10-record sample, then one fixed fee per build, from $499 for 1,000 records, and there is no upper limit. Most builds arrive within 3 business days, with 50,000+ record builds given a committed delivery date in your build plan. Every email is checked again on delivery day, and any bounce is replaced free.
Hire, tool up, and train.
Hiring people, buying tools, and training before anyone is productive all cost you money before the first usable record lands.
You write the brief. We hand you the finished file.
A small team builds your audience by hand to your exact brief, and you see a free sample before you commit a dollar.
BeSpoke follows 3 steps, brief to your master file. Hands-free for you, hand-built by us. No headcount, no platform to learn, no commitment until the sample lands.
You write a short brief: who you want to reach, where they are, which fields matter most, and an example or two. We come back with a build plan and the questions worth asking before any work starts.
We build a free 10-record sample on your exact criteria. Every email checked and deliverable, every record carrying a public source link, so you judge the fit before paying anything.
Approve the free sample, pay the invoice, and the full file follows, usually within 1 business day up to 10,000 records, at most 3 business days up to 50,000 records, deduplicated, formatted for your CRM, checked on delivery day. The sample you approved sets the bar: if any part of the full file lands below it, we rework the build with you until it is right.
If you name it in your brief, we build the column.
Your BeSpoke file is built to your brief, not a one-size-fits-all export. You name the audience, the fields, and the format, and we build exactly that. Every record carries a public source link, open it and check it yourself, and we never fabricate.

A luxury auction house needed verified Patek Philippe collectors with documented 6-figure purchases in the past 24 months. Buyers, not browsers. We built the audience from auction records and collector communities. Typical BeSpoke samples reach your inbox inside 24 hours of your brief. 2,512 records arrived 3 business days later, each with its public source link on the record.
Every build carries the 97% deliverability guarantee, with any bounce replaced free.
The first private-sale invitation returned a 4× reply rate against the client's existing buyer list. 3 pieces sold above estimate within 48 hours. The house has since commissioned 3 more builds.Anonymized at the client's request, the same privacy every BeSpoke client gets. Results vary by audience and volume.
500+ reviews across 6 platforms. Rated 4.9 out of 5 on both G2 and Capterra.
Pros
"Finding real estate agent contacts without having to pay for pricey database subscriptions has been made possible by Bookyourdata. Building a targeted outreach list was made simpler by my ability to filter agents based on area, broking size, and role. Verifying that the contacts were pertinent to our campaigns was made easier by the option to view sample data prior to purchase. All things considered, the contact precision has been dependable enough for steady outreach."
Cons
"Slightly deeper contact coverage might be beneficial for certain specialised geographical sectors."
Pros
"It's been a great resource for finding accurate and well-segmented contact lists. It has been a valuable tool in expanding our CRM and addressing more of our TAM."
Cons
"Niche industries like cannabis have limited contacts, hard to find long term value for these types of business sectors."
Pros
"We have found fresh leads because to BookYourData's unique email verification technique, which has been very accurate. There are no long-term obligations and their pricing structure is adaptable reasonably priced."
Cons
"It would be beneficial to have extra learning resources, such training videos, to enhance the experience."
Reviews above reflect BookYourData's self-serve database, not BeSpoke. The same research team runs both, and the coverage gaps a few reviewers flag are exactly the audiences BeSpoke hand-builds.
Private list building
But BeSpoke builds it for you.
Across 220 real customer briefs, one theme kept surfacing: the audience worth the most to you is the one no database produces. You name them. We verify every record by hand and send you the finished file.
Try asking a database for
Filters, dropdowns, saved searches, pointed at your audience
The filters match the parts of the brief this database has fields for. The remaining item is not recorded for any contact, so you email the full matched list and never find out which of those contacts actually fit.
Building by hand from public records, registries, filings, and press. Researchers also pull from licensing boards, trade associations, permit filings, event exhibitor lists, and company registries when mapping a sector.
Researched after you order, for your brief
Your list is built when you order, never pulled from one provider's database compiled months or years ago.
active listings over $5M verified…and on to the final record of your order, each one checked by a human researcher
Your build goes as far as your brief needs, with no upper limit, and bigger ones are priced in your build plan.
Every record cites a verifiable public source.
Records shown are fictional examples, never real contact data.
The same method at every size, from 1,000 records up, with no upper limit. Straightforward builds often land well inside the 3-day window. Builds of 50,000+ records get a committed delivery date in your build plan.
The groups below are the ones whose briefs reach our desk. The industry matters less than the condition you need to be true. A precise ask beats a broad vertical every time.
Why each group lands here
The tight end of a real ask is never an industry. Real asks describe conditions true today, not industry labels.
Why it costs more
Searching a database yourself is cheaper, but four things happen when our researchers build your list for you instead.
We do all the work
No tool to master and no filters to fiddle with. You send the brief and wait for delivery.
Any audience you can describe
Tell us the audience and criteria you want. We build it, even beyond what database filters offer.
1,000+ live sources, not one
A single database is limited to its stored records. We run 1,000+ sources as a waterfall: if one comes up empty, another steps in.
Built when you order
A stored list can be 6 months, 1 year or even 2 years old. Yours is gathered only once we start.
That is why it costs more: a far wider net, and data gathered close to the day you get it.
Records shown are fictional examples, never real contact data.
On some briefs, all this compounds to up to 3x more usable contacts than the same brief run through a contact database's filters. The gain varies by brief, and your BeSpoke file holds every record we found and verified.
| A common data provider | BeSpoke done for you | |
|---|---|---|
| Targeting criteria | Fixed filter fields like industry, title, location, and technographics. | Write conditions in plain language, our researchers build to them, like dentists opening a 2nd practice or firms with active contract bids. |
| Data sources | Contacts come from one static data source. | You see exactly where every contact came from, each record links to a verifiable source outside pre-built databases. |
| Custom fields | Exports cover only the fields the provider defines. | Your file gains custom columns for any field you name. |
| Who does the work | Your team runs the searches, applies filters, and exports the contacts. | 1 brief, researchers handle every record. |
| Free sample | You run the search yourself, seeing only what the database already holds. | Proof before payment, 10 sample records arrive with a clickable source link on each. |
A common data provider sells records gathered in advance. BeSpoke delivers records searched after you order.
We read public sources by hand on top of 1,000+ data providers, for example: licenses and registries, property records and court filings, company filings, press and company websites, and associations, events and permits.
What is a license registry?
A license registry is a public record that lists license holders, license numbers and current status. BeSpoke researchers check licensing boards, state registries and company registries, confirming each license is active and held by the contact's company.
What is a property record?
A property record is a public record that lists who owns a property and what it sold for. BeSpoke researchers confirm a closed sale from county commercial deed filings and county property appraiser records, and a named general counsel from active court records.
What is a company filing?
A company filing is a public record kept by a government office, listing who runs the firm. BeSpoke researchers read a firm's SEC Form D to confirm the firm is raising investor capital.
What is a press release?
A press release is a public announcement a firm issues to share its own news. BeSpoke researchers read a firm press release about a second office opening and confirm the opening for the contact's company on that contact's record.
What is an event exhibitor list?
An event exhibitor list is a public list of companies exhibiting at a trade show, put out by the organizer. For each record, BeSpoke researchers confirm trade association membership, permit filings and exhibitor presence at trade shows.
The email, the person and the phone number each get their own check before delivery, never a shared check for the whole record. The email gets checked again on delivery day.
Every email is verified live on the day we deliver, and any address that bounces is replaced free.
Before delivery, we confirm every person still works at the company, drawing on LinkedIn, corporate registries, government records and the open web.
Dead numbers, company main lines, and numbers that only look like mobiles are taken out of your mobile and direct dial columns.
One-time by default, per build. Same quality bar at every tier.

The BeSpoke guarantee
If your audience turns out smaller than the tier you ordered, you only pay for the records we deliver, at the per-record rate of the tier you ordered.
Data freshness
A list compiled before you asked gets older every month. Contacts change jobs, emails bounce, and a third-party file built last quarter holds records that no longer point to a real person. A BeSpoke list is researched only after you order, so every contact is found in the very week your file arrives. Nothing was assembled in advance and left waiting for a buyer.
| Others | BeSpoke Built from live sources | |
|---|---|---|
| When it was built | Long before you asked. The compile date rarely makes it onto the file. | Built after you order, never before. Research starts when you say go. |
| Freshness on arrival | Often months, sometimes years, since the last compile. | Minutes. Source to file to final check inside one build window. |
| 6 months later | The same records, 6 months older. | Rebuilt to the same brief, on whatever schedule you set. |
The comparison above applies to third-party sellers of static list files, not to BookYourData's own catalogue. The third line is why BeSpoke offers a recurring refresh. A list born fresh is worth keeping fresh.
One-time or recurring
Each BeSpoke build arrives as an Excel file built to your columns, in up to 3 business days for most builds, ordered once or as a recurring refresh every month, every week or every day.
One-time by default: one BeSpoke build, one fixed fee, the file is yours. If you order one build, a later refresh of that list is priced as its own small build.
When a brief needs only phone numbers, Direct dials & mobile numbers finds direct dials and mobile numbers for the people you name.
Delivery options
If you already hold a contact list, our data append services for business and consumer lists fill in the missing emails and mobile numbers.
Each recurring refresh brings a new file of your audience, built to the same brief, on your schedule. We hold your brief, rerun the research every time, and verify each refresh the moment it lands. The recurring file is your own, exclusive to you, and yours to keep.
One example: every agent newly licensed in the past 30 days, delivered on the first of each month.
A recurring refresh gets its terms agreed up front, like 3 updates a month priced in advance. How far you take it is up to you.
From the founder

"I believe you should never pay for a list you have not seen prove itself. That is why every BeSpoke build starts with a free 10-record sample, and why every email gets its final check on the day we deliver, not the day we found it."
You bring the client and brief, our team hand builds the list, and the file carries only your brand. You set your price above ours and keep the difference, with a free 10-record sample first on every build.

Name the audience, name the signal, name the fields. The rest is on us, with zero commitment until the sample lands. Run it through your own stack and tell us if it holds.
