B2B lead generation agency.
JAAB builds B2B acquisition programs on the ad platforms that reach your target (Search, LinkedIn, Meta or Reddit), connected to your CRM and your sales cycle. A lead only counts if it becomes an opportunity, then a customer: that is the number your campaigns are managed on.

Each ad platform produces leads of different quality. Comparing ad platforms on cost per lead alone sometimes rewards the one that fills the CRM with contacts who never sign. Choose an ad platform to see how the cost changes at each stage of the sales cycle.
Fictional values, for illustration only. Actual differences depend on your offer, your sales cycle and your market: that is precisely what campaign management measures.
The lead goes back to the ad platform, qualified.
Ad platform algorithms learn from the conversions sent back to them. If all they see are completed forms, they look for more forms. When the CRM sends them qualified leads and closed sales, they look for profiles that resemble your customers.
This is the core of our approach. We integrate your programs with your CRM, whatever it is (HubSpot, Pipedrive, Sellsy or another tool), to send this information back to the ad platforms.
Each ad platform has its role, the media plan strikes the balance.
No ad platform is reserved for B2B. Each brings its own targeting and performance capabilities: Search captures expressed demand, LinkedIn targets job functions and companies, and Meta and Reddit also deliver very good campaigns. The challenge is to balance the media plan according to your goals, your audiences and your budgets.

Lead generation, at the heart of our expertise.
JAAB works with more than fifty international clients, with a 97% recommendation rate. The agency was founded in 2023 by two former Google and Twitter employees and now has a team of seven. It holds Google Partner Premier status.
We prefer to manage a program on margin rather than on the numbers shown by the platforms, and our fees stay separate from the media budget. Ad accounts remain our clients' property.
B2B leads, in practice.
01What does a B2B lead generation agency do?
It builds and manages the campaigns that bring qualified contacts to a sales team: Search, LinkedIn, Meta, Reddit and other ad platforms, forms, conversion tracking and the link with the CRM. At JAAB, campaigns are managed on cost per qualified lead and customer acquisition cost, not on lead volume alone.
02Which ad platforms should you use to generate B2B leads?
There is no single answer. Search captures expressed demand, LinkedIn targets job functions and companies, Meta and Reddit also deliver very good B2B campaigns, and Microsoft Ads extends Search. Each ad platform brings its own targeting and performance capabilities: the challenge is to balance the media plan according to your goals, your audiences and your budgets, then verify it through measurement.
03How do you measure lead quality?
By following each lead in the CRM through to qualification, then to the sale. This information is reconciled with ad platform data to calculate a cost per qualified lead and a customer acquisition cost for each campaign.
04Which CRMs does JAAB work with?
With each client's CRM, whatever it is: HubSpot, Pipedrive, Sellsy or another tool. Acquisition programs are integrated with it to track leads and send qualification information back to the ad platforms.
05Why send qualified leads back to the ad platforms?
Because bidding algorithms learn from the conversions they receive. If all they see are forms, they look for forms. With qualified leads and offline sales, they look for profiles close to your customers.
06Is LinkedIn enough for a B2B strategy?
Rarely on its own. LinkedIn targets decision-makers precisely, but its cost per contact is high. Search, Meta or Reddit complete the media plan, and all ad platforms are compared on customer acquisition cost.
07Who owns the accounts and the data?
You do. The ad accounts remain your company's property, and JAAB accesses them from its admin accounts, with permissions you can revoke at any time.
