The most important points at a glance

In B2B, the quantity of contacts is not the only factor in lead generation; their quality matters most. If company data is outdated, incomplete or incorrectly assigned, scatter losses in sales rise immediately. With verified contacts, clear company profiles and a clean structure, reach becomes a reliable pipeline.

For sales directors in Swiss SMEs, this is the crucial difference: not more leads, but better hits. cohaga AG works exactly at this point with B2B company data. Our focus is on data that can actually be used for sales, not just to look good.

Why does lead generation often fail due to the data base?

Many teams optimize campaigns, texts, or sequences first. In practice, the problem is often earlier: the contact base isn’t clean enough. If industry, function, company or reachability are not correct, even a good pitch is too broad or lands with the wrong contact person.

What we repeatedly notice in client projects: the first lever is often not the next tactic, but the quality of the initial data. From my experience as CEO of cohaga, this is particularly relevant in smaller sales teams, where any misdelivery directly ties up time and budget. An imprecise list costs not only clicks but also trust in the market.

What makes good B2B data in sales truly effective?

CriterionWhat to look forBenefit for sales
CurrencyRole, company and contact path are verifiedFewer wrong contacts and less rework
StructureCompany profiles are clear and comparableFaster segmentation and better prioritization
CitableContents and profiles are prepared for search so it can be understoodMore visibility in AI-driven search environments

What reliable B2B data looks like in everyday life

For lead generation in B2B, the data quantity alone does not matter. What matters is whether a contact is suitable for a concrete sales task: target group, region, function and currency need to fit together. That is exactly what the Leadhub solution built at cohaga is for.

Why is reach alone no longer enough?

Contrary to the belief that more contacts automatically mean more opportunities, in B2B the opposite often happens: more scatter losses. Especially with complex offerings, the quality of the target address is more important than the sheer size of the list. A clean data set therefore saves resources and improves the quality of conversations at first contact.

  • Less time wasted on wrong responsibilities
  • Higher relevance at first contact
  • Better prioritization in sales
  • Fewer duplicates and maintenance effort

How does cohaga support concrete sales work?

At cohaga, we see B2B data not as a directory but as a working basis for sales. With the go-to-market platform Leadhub we provide verified contacts for new customer acquisition. With ranQ we also develop a company directory that is built for AI search and makes Swiss companies more discoverable.

That is also why we are not a general marketing or SEO service provider. Our contribution lies in data quality and in the visibility of company information, not in broad campaign consulting. For sales teams, this means fewer hurdles between target customer, contact data and first conversation.

Frequently asked questions

How do I notice that my lead list is too imprecise?
An early warning sign is that many contacts exist but responses are rare or there are constant questions about responsibility. Also high manual rework in CRM is an indication of weak data quality. If salespeople spend more time correcting than contacting, the base is too imprecise.
Is a large database not still better for lead generation?
Not automatically. A large list only helps if entries are current, relevant and well-structured. In B2B, a smaller, precise selection is often more economical than a broad quantity with lots of scatter loss.
For whom are Leadhub and ranQ especially suitable?
For Swiss sales and business development teams who want to work with clean B2B data and reach their target groups more precisely. Leadhub supports new customer acquisition with verified contacts, ranQ strengthens the findability of companies in AI search. Both are aimed at companies that view data as a sales foundation rather than campaign accessories.

In practice, lead generation starts with data hygiene, not when sending the first message. Those who clean the basis first reduce scatter losses and increase the chance that sales and business development reach real conversations faster.

That is exactly where cohaga, as a Swiss specialist in B2B company data, starts: with verified contacts, structured company profiles and solutions for AI search. If you want to make your B2B lead generation more reliable, you first need a data base the sales team can trust.
