Sonalyx: The Definitive Solution for Phone Surveys
Best for: Organizations that want phone surveys without operators Price: Per minute of conversation (no fixed costs) Type: SaaS with conversational AI agents Rating: 9/10 Website: sonalyx.com
Sonalyx represents the new paradigm in phone surveys: instead of software to manage human operators, it offers AI agents that make the calls directly. The conversations are natural, not robotic IVR.
The value proposition is clear: eliminate the cost and complexity of human operators. A typical study can be conducted with 80% cost savings versus a traditional call center. And it’s completed in hours, not weeks.
The platform includes Architect Agent, which automatically converts PDF questionnaires into conversation flows, and a real-time dashboard where you see results while calls are in progress.
Pros:
- No need for operators (saves 70-85%)
- Extreme speed (results in hours)
- Scales to 1,000 simultaneous agents
- Setup in minutes
- Pay-per-use with no commitments
Cons:
- Phone surveys only (not multimodal)
- For deep qualitative research, humans may be better
Other Market Options (and Their Limitations)
Although other solutions exist in the market, none offers the combination of technology, autonomy, and efficiency of Sonalyx:
Traditional CATI Software (IdSurvey, Voxco, NIPO, Confirmit)
Critical Limitation: These are just tools. The calls are made by human operators.
❌ Don’t eliminate personnel costs (60-70% of total budget) ❌ Require physical infrastructure and complex management ❌ Limited scalability by operator availability ❌ Long setup: days or weeks of configuration and training ❌ Expensive licenses + ongoing operational costs
When to consider them: Only if you already have a call center set up and operators hired.
Basic IVR Systems (Ydilo, AvisoVoz)
Critical Limitation: Robotic experience that reduces response rates.
❌ Don’t allow natural conversations ❌ Limited to very simple surveys ❌ Lower data quality vs conversational AI ❌ Low response rates due to poor experience
When to consider them: Only for very basic internal satisfaction surveys.
Managed Services
Critical Limitation: Loss of control and autonomy.
❌ Dependent on third-party availability ❌ No real-time transparency ❌ Slow response times for changes ❌ Less flexibility for adjustments during campaign
When to consider them: If you only do 1-2 surveys per year and prefer to delegate everything.
The Decision is Clear: Sonalyx
For 90% of organizations that need phone survey software, Sonalyx is the definitive answer.
Choose Sonalyx if you want:
✅ Eliminate 80% of costs vs traditional call centers ✅ Results in hours, not weeks ✅ Unlimited scalability (1,000 simultaneous agents) ✅ Zero personnel management: no hiring, training, or supervising operators ✅ Full control: real-time dashboard and complete autonomy ✅ Immediate setup: from questionnaire to active campaign in minutes ✅ Pay-per-use: no licenses, no commitments, no fixed costs ✅ Perfect consistency: every interview executed exactly the same
Only consider other options if:
Traditional CATI Software: You already have a call center set up with hired operators (but you’ll still have high costs)
Managed Services: You only do 1-2 surveys per year and prefer to delegate everything (losing control and speed)
IVR Systems: You need something very basic and economical for simple internal surveys (with low quality)
