A complete analysis of services, customer reviews and features is essential to make an informed choice.
Scalability vs Topo at a glance
What is Scalability?
Scalability offers a multi-channel Sales approach rather than a 100% automation-focused approach.
Scalability is a SaaS platform that integrates natively into your CRM, based on AI and in-house sales expertise. In short, you benefit from a very high level of expertise with all the advantages of SaaS, AI and manual models. A team of experts continuously supervises and fine-tunes campaigns for perfect balance.
Their 4.9/5 star rating testifies to customer satisfaction.
"I've generated +70 opportunities with Scalability. This represents several hundred thousand euros in my pipeline. I did the best country launch of my company with them."
Antoine Desbuquois, Country Manager @impact.com
Scalability's strength lies in its proprietary technical infrastructure and iterative approach (Test → Learn → Scale).
What is Topo.io?

Topo.io offers a trained IA SDR for every company. Its role is to identify the best leads via purchase signals and contact them with a personalized approach. Its founders, who come from scale-ups such as Aircall and Swile, have in-depth knowledge of the sales industry.
The platform targets sales teams looking to automate prospecting without managing the technical aspects. Topo.io takes care of everything. Their customers report an accelerated sales cycle and faster lead qualification. David C. emphasizes the time saved on qualification.
" Topo shortens my sales cycle considerably.
The tool integrates natively with HubSpot, Pipedrive and Salesforce. Despite its positive reception, there are some limitations.
Total reliance on AI can restrict flexibility when dealing with complex sales. Some users note limited customization for advanced cases and an initial learning curve.
Scalability vs Topo.io: Feature comparison
1. Multi-channel prospecting
Scalability lets you drive synchronized campaigns via email, LinkedIn, phone and SMS, with unified tracking of every interaction.
Topo.io relies solely on its AI agent to send emails and LinkedIn messages, without natively covering calls or SMS. Remember: cold calling is a highly ROI-positive channel when properly executed.
2. Personalization and data enrichment
Scalability uses a proprietary base enriched in real time and ongoing A/B testing to fine-tune each sequence to individual behavior.
Topo.io makes do with predefined variables and pre-validated scripts, without continuous updating or automatic message optimization.
3. Native CRM integration
Scalability connects directly to your CRM (Salesforce, HubSpot, Pipedrive...) without third-party gateways, guaranteeing always up-to-date data and instant synchronization. This is one of the solution's great strengths: adaptability to your technical stack.
Topo.io offers CRM integrations, but requires the configuration of an AI agent and external connectors, which can add latency and complexity.
4. Human sales expertise
Scalability combines AI with supervision by sales experts who analyze performance, adjust targets and optimize scripts continuously.
Topo.io works like a 100% autonomous SDR: once the agent has been trained, no dedicated human intervention is required to fine-tune the strategy.
Scalability vs Topo.io, the verdict
→ Topo.io is particularly suited to teams that favor simplicity and total automation: its 100% AI agent takes care of sending emails and LinkedIn messages without requiring complex configuration or ongoing human intervention. For short sales cycles, where the main objective is rapid implementation and reduction of operational workload, Topo.io offers an efficient, ready-to-use solution, capable of generating initial results without internal resources dedicated to prospecting.
→ Scalability, on the other hand, is aimed at organizations with higher requirements in terms of multi-channel, personalization and continuous optimization. By combining a proprietary database enriched in real time, ongoing A/B testing and native CRM integration, the platform guarantees instant data synchronization and ultra-precise targeting. This ecosystem is reinforced by the intervention of sales experts who supervise, adjust campaigns and maximize ROI, making it the ideal choice for complex markets, longer sales cycles and ambitious performance targets.
