How to choose

What to look for in a lead-gen agency.

Specialisation

A partner who knows your industry beats a generalist running templated outreach.

Qualification

Insist on human-screened meetings against your exact criteria, not raw lead volume.

Data ownership

You should own every contact and conversation, in your CRM.

Transparency

Weekly reporting on touches, replies, and booked meetings, not vague monthly summaries.

Pricing model

Predictable retainers align the agency to quality; watch for long lock-ins.

FAQ

Choosing an agency, answered

What is the best B2B lead generation agency?
There is no single best agency for everyone. The right choice depends on your industry, deal size, and whether you need appointment setting, ABM, or full-funnel demand generation. Technology companies are usually best served by a specialist; generalists suit broader B2B. Compare on specialisation, qualification rigour, data ownership, transparency, and pricing model.
How much does a B2B lead generation agency cost?
Most agencies charge a flat monthly retainer scoped to your target volume and channels, while some offer pay-per-meeting pricing. Expect a custom quote based on your ideal customer profile rather than a fixed list price.
Should I hire a specialist or a generalist agency?
If you sell technology, a specialist that only does B2B tech go-to-market will usually craft sharper messaging and reach the right buyers faster. Generalists can work well for broad, horizontal offers.
