WHAT YOU PAY FOR

WHAT YOU RECEIVE

FIT TO YOUR STAGE

Outcomes and infrastructure delivered - value-based, matched to your growth stage. No billing for hours logged or emails sent.

~20 Plug&Play services matched to your maturity. The right service for where you actually are.

Outbound, CRM data orchestration, and GTM consulting - three disciplines built as one connected system.

Other agencies

Time spent or volume of activity - regardless of whether the pipeline moves.

Leads generated during the contract. When the retainer stops, the pipeline stops.

FAQs

Answers to the questions we hear most from B2B sales and growth leaders.

How much does cooperation cost?

Our lowest cooperation package starts from 1 800 USD net monthly. Most clients choose a package worth around
4 500 USD net monthly. With at least 3 months of cooperation.

How long will I have to wait for results?

We understand that you expect a return on investment. First results are noticeable about 2 weeks after the campaign starts and around 4 weeks from the beginning of cooperation. However, remember that results may vary depending on the specifics of the company, services or products offered.

How many people do I need to manage the process?

At minimum, one person who will dedicate time to handling inquiries from potential clients. We can adapt campaigns to client requirements in terms of the number of salespeople, number of prospects in the campaign, and campaign duration. We work with individual salespeople as well as sales teams.

When does it make sense to hire a GTM agency instead of building in-house?

Building in-house makes sense when you have a dedicated RevOps or GTM team with the capacity to own the toolstack, run experiments, and iterate week over week. A GTM agency makes sense when that team doesn't exist yet, when results are needed faster than hiring allows, or when the infrastructure needs to be built before you know what roles to hire for. Most companies hire an agency to build the system, then hire internally to run it.

What separates a good outbound lead generation agency from a bad one?

The clearest signal is what the agency owns. A good outbound lead generation agency owns the data quality, the hypothesis behind the messaging, and the iteration process when results don't come. A bad one owns the send volume and calls it delivery. The second signal is what you're left with after the engagement - a working system or a spreadsheet of leads that goes cold the moment the retainer ends.
