The challenge

Recruiting and retaining skilled phone interviewers was becoming increasingly difficult and expensive. Project timelines were slipping due to fieldwork delays, and clients were demanding faster turnaround without sacrificing data quality or methodological rigour.

The solution

SignalLine AI was deployed alongside the agency's existing CATI operations to handle high-volume, structured phone surveys. AI agents followed the agency's questionnaire designs with full branching logic, captured responses in their preferred data format, and maintained the methodological consistency their clients expected.

The results

The agency tripled their effective survey capacity without hiring additional interviewers. Cost per completed interview dropped by 42%. Project timelines shortened significantly, with a 10,000-respondent study completed in 5 days that previously took 3 weeks. Data quality scores remained at 98.2%.

We were sceptical at first, but the quality of the AI interviews matched our experienced interviewers. Our clients cannot tell the difference, and we can now take on projects we would have previously turned down due to capacity constraints.
