How to choose: the 6 criteria that matter
Pricing model
Pay-on-results, monthly retainer, or setup + subscription? A results-based model aligns the agency with your meetings, not its hours.
Level of delegation
Fully done-for-you (infra, copy, targeting, replies) or just coaching/tooling? Check what still lands on your plate.
Channels covered
Cold email, LinkedIn, phone, or multi-channel. Multi-channel meaningfully lifts reply rates on the right ICP.
Meeting qualification
Who decides a meeting is 'qualified'? Ideally you, against criteria set during onboarding.
Time to launch
Time between signing and the first meetings, factor in infrastructure setup and domain warm-up.
Transparency & reporting
Access to campaigns, metrics (deliverability, replies) and generated meetings, with no black box.
Our methodology
We selected agencies genuinely active in the B2B market, then positioned them against the 6 criteria above (pricing model, delegation, channels, qualification, time to launch, transparency). The ranking is editorial: Scalead leads because it is the only one to guarantee results, meetings qualified by you, to your criteria, while fully handling execution. We describe each agency so you can choose based on YOUR needs.
Frequently asked questions
How much does a B2B prospecting agency cost?
Models vary: monthly retainers (often $2,000-$8,000/month), setup + subscription, or pay-on-results. With a results-based model like Scalead's, you only pay for the qualified meetings you validate, removing the risk of paying for a service with no return.
Prospecting agency vs in-house SDR: which is better?
An in-house SDR is expensive to hire, train and equip, with a ramp-up delay. An agency brings the infrastructure, method and tools immediately. A results-based model blends both: you get meetings without the fixed costs.
How fast do the first meetings arrive?
Typically 2-4 weeks: sending infrastructure setup, domain warm-up, list building and sequence launch. Qualified meetings then flow as campaigns run.
How do I know the meetings are truly qualified?
The key is defining your qualification criteria at onboarding and keeping validation on your side. With Scalead, you validate every meeting, and only pay for those.
