Customer reviews of Growth Room
Growth Room reviews
Available customer feedback shows overall satisfaction:
"We needed to create a scalable process for generating leads. Growth Room produced leads and distinguished MQLs from SQLs, enabling our sales team to convert more effectively. We have closed over 150 new deals and generate 35 MQLs per month."
"Growth Room has generated as much business as our historical channels. We had nothing in place before this collaboration. In the end, this channel now represents a share equivalent to our traditional channels."
The company secured 52 appointments with SMEs & Key Accounts, with a response rate of 11%.
The advantages of Growth Room
✔️ Human expertise: Access to a team of specialized consultants to fine-tune your messages and channels.
✔️ Full-funnel strategy: from SEO to paid campaigns, outbound and HubSpot marketing automation.
✔️ Reporting and shared KPIs: Customized dashboards and weekly reviews to adjust strategy.
✔️ Data-driven approach: Consultants trained in data tracking and analysis for optimum performance.
The disadvantages of Growth Room
❌ Agency dependency: internal skills development can be slowed down by outsourcing execution.
❌ High budget: As a full-service agency, packages often start above €3,000 / month, unsuitable for very small structures.
❌ Limited control: Without direct access to a tool, real-time adjustments are impossible, unlike with SaaS platforms.
Case study: Fleurs d'ici
The case of Fleurs d'ici is a perfect illustration of the Growth Room approach. This company specializing in local flower delivery had no plan in place before 2021. The initial objective was to test their subscription offer with new targets.
Methodology applied: After several tests, Growth Room identified the most receptive CSR audience. The campaigns were then optimized.
- 52 meetings generated with SMEs & key accounts
- 11% response rate
- 100+ qualified leads from prospects such as Renault, Chateauform and several town halls
- A channel that generates as much business as traditional channels
Fleurs d'ici has continued with its post-accompaniment campaigns, proving the sustainability of the processes put in place.
However, the impossibility of adjusting sequences in real time remains a limitation that platforms like Scalability circumvent thanks to their direct access to automation tools.
