DATA INTELLIGENCE / CUSTOM CONTACT DATA

Nobody Sells A List Of Exactly Who You Need.

Prepackaged lists are built for the average buyer. If your audience is narrow, a niche specialty, a specific job function, a certain size of company running a certain tool, that list will be mostly people you cannot use. Custom data starts from your spec instead of a shelf.

Reach Or Relevance. Pick The One
Your Campaign Needs.

A prepackaged list is cheaper per name and fine when you want volume and brand recall. Custom is the better buy when a wrong name costs you more than a missing one. Most teams need both at different moments, so the question is which job this campaign is doing.

A prepackaged list

Pick a segment → Buy the block → Filter it down → Use a slice

Fast and cheap for wide reach. You take the whole block and pay for names outside your target, then trim by hand.

A file built to your spec

Define → Build → Verify → Deliver

Slower to produce and narrower by design. Every record clears your criteria before it reaches you, so your team works a list they can trust.

How A Custom Build Works

STEP 01

You describe the audience

Industry, titles, geography, company size, technology in use, and anyone you want left out. Send your best customer list instead if that is easier. We can work backwards from what already closed.

STEP 02

We build and check it

Records are assembled from public filings, directories, trade show lists, subscriptions and opt in sources, then matched and verified. Hard fields get checked by hand. Anything we cannot confirm is left out rather than filled in.

STEP 03

You approve a sample first

A slice of the file comes to you before the rest. Check the fit and the field quality. If the spec needs tightening, we tighten it and rebuild, then deliver in your format.

It All Comes Back To One Thing. Everyone On The File Fits.

No paying for waste

A block of 50,000 where 4,000 fit is not cheap. It just moves the cost somewhere you do not measure.

Sharper messaging

When every reader holds the same job in the same kind of company, you can write one email that lands.

Reps stop filtering

Nobody has to open a row and decide whether this person was ever worth calling.

Cleaner reporting

Reply rates mean something when the denominator is people who could realistically buy.

An aviation manufacturer put 700K dollars of sales through a custom LakeB2B database.

Narrow sector, small buying population, no list on the market that matched it.

Frequently Asked Questions

A contact file built to a specification you set rather than a segment pulled from an existing list. You define industry, titles, geography, company size and other criteria, and only records meeting them are built.

A prepackaged list already exists, so you buy a block and filter it down. A custom file is assembled against your criteria, so filtering happens before delivery instead of after.

Up to 75 intelligence fields per record across person, contact, company, location, technology and signal groups. Most teams use between eight and twenty.

Public records and government listings, annual reports and regulatory filings, trade shows and attendee lists, business directories, publication subscriptions, postal service updates, and opt in campaigns and surveys.

It depends on audience size and how hard the criteria are to confirm. A timeline is agreed with you once the specification is set, before work starts.

Collection and processing follow GDPR and CCPA requirements with careful handling for healthcare records. Opt out requests are honoured and a data processing agreement can be signed.

Yes. A sample of the file is delivered before the full build so you can check that records match your specification.
