B2B SaaS: the Growth Room method approved

Growth Room supports B2B SaaS publishers with a multi-channel paid acquisition methodology (Meta Ads, Google Ads, LinkedIn Ads), structured to generate a regular flow of leads, from 16 to 120 leads per month depending on the case, while mastering CPL and maintaining a profitable ROAS, as shown by the results obtained with HeyTeam, Waalaxy, Strapi or Erplain.

‍

In a B2B SaaS, the subject is not only about launching campaigns. The real issue is maintaining a rhythm: leads that arrives every month, without seeing the costs get out of hand and without attracting off-target requests.

The cases presented here cover different contexts: some teams seek to accelerate, others to launch an offer, others to regain control over a channel that was becoming unpredictable. What these projects have in common is a pragmatic approach: clarifying the target, putting the acquisition in order, then improving in stages.

Below you will find a selection of SaaS B2B and Tech customer cases. Each sheet shows the context, what was achieved and the result obtained, based on the items in your list.
