The short answer

The short version.

Part 1 of the lead generation companies series, a buyer's guide from first search to signed contract.
The market has four types: data providers, database tools, appointment setters and full-service agencies. They sell different products at prices 100x apart.
Most buying mistakes come from comparing across types: a data subscription and an agency retainer are not alternatives, they are different products.
If you have people who can call, you want a data provider. Everything else buys labour you may already have.

Search for lead generation companies and the results mix four completely different businesses that happen to share a keyword. This is part 1 of a buyer's guide series: what each type actually sells, so you can compare like with like. Part 2 covers how to compare them, part 3 the pricing, and part 4 how to test one before you sign.

Type 1: data providers

Data providers sell screened contact records: a named person matching your profile, with a mobile number or direct dial and a work email, delivered on a schedule.

This is the raw material of outbound. You describe the ideal customer, the provider builds and checks the records, and your team works them. Pricing is per contact, typically 10 to 50 cents at monthly volume. LeadNumbers is this type: screened contacts at 15 cents at 500 a month down to 10 cents at 5,000, delivered every business day.

What you get is leverage on your own callers. What you do not get is anyone doing the calling.

Type 2: database tools

Database tools sell seats and credits to search a large contact index yourself, instead of receiving finished records.

You are buying access, not output. Your reps filter, export and clean the records, and the meter runs on credits whether the record turns out usable or not. The headline credit price looks low; the honest price per usable contact, after wasted credits and rep time, is usually several times higher. These tools suit teams with dedicated researchers and time to spare.

Type 3: appointment setters

Appointment setters sell booked meetings: their callers dial, qualify and put meetings on your calendar, priced per meeting or per month.

This is the outcome product. Typical pricing is $100 to $800 per booked meeting, or a monthly retainer for a target number of meetings. It suits teams with closers but no prospectors. The trade-offs are cost per meeting, variable quality of qualification, and the fact that the contact data usually stays with the setter when the engagement ends.

Type 4: full-service agencies

Agencies sell a managed program: strategy, content, ads, outbound and reporting, on a monthly retainer.

Retainers commonly run $3,000 to $15,000 a month and up. You are buying a department, which makes sense when you need several channels built at once and have the budget to fund a team. For a company that simply needs conversations this quarter, an agency retainer usually means paying for a strategy phase before a single dial happens.

Type	What you get	Typical pricing	Best for
Data provider	Screened contacts on a schedule	10 to 50 cents per contact	Teams with callers
Database tool	Self-serve access to an index	Seat plus credits	Teams with researchers
Appointment setter	Booked meetings	$100 to $800 per meeting	Closers without prospectors
Full-service agency	A managed multi-channel program	$3,000+ per month	Funded teams building channels

The four types of lead generation company

Which type fits you

If you have people who can call, buy data. If you have closers but nobody to prospect, buy meetings. If you need whole channels built, buy an agency. If you have researchers, buy a database seat.

The deciding question is which labour you already own. Every type above the data layer is, at heart, a data layer plus labour. Teams that already employ callers pay a large premium for work they can do themselves, which is why a data subscription is the default starting point for most small and mid-size sales teams.

Nothing stops you combining them. A common setup is a data subscription feeding an in-house caller, with an appointment setter added for overflow in busy months. What rarely works is skipping the question and buying whichever type has the best sales deck.

Key takeaways

Four different businesses share this keyword. Identify the type before comparing anything.
Data is the cheapest layer and the one every other type builds on.
Buy the labour you lack, not the labour you already employ.

Frequently asked questions

What does a lead generation company do?

It depends on the type. Data providers supply screened contacts, database tools sell search access, appointment setters book meetings, and agencies run whole programs. The phrase covers all four.

Which type of lead generation company is cheapest?

Data providers, at 10 to 50 cents per contact. They are also the best value per meeting if you already employ people who can call, because every other type charges you again for labour.

Is LeadNumbers a lead generation company?

Yes, the data provider type. You describe your ideal customer, and screened contacts with mobile numbers or direct dials arrive every business day, starting at $75 a month for 500.

Can I use more than one type at once?

Yes. A data subscription feeding your own callers, plus an appointment setter for overflow, is a common combination. The mistake is paying two companies for the same labour.
