About SignalLine AI
A UK company building telephone survey and reception fieldwork on conversational AI voice agents.
Making voice operations scalable and intelligent
Organisations across research, housing, public sector, and enterprise operations depend on phone calls to gather data, deliver services, and build relationships. But traditional calling operations are expensive, hard to scale, and difficult to measure.
SignalLine AI exists to change that. We build AI voice agents that handle the calls your teams cannot get to — with consistent quality, full transparency, and measurable outcomes. We are not replacing human connection. We are extending it to every call that matters.
Where we are
SignalLine AI is the trading name of Sparkline Consulting Ltd, a UK company registered in England (No. 16269648), registered with the ICO as a data controller (ZC143411). We build and run the telephony ourselves rather than reselling someone else’s platform.
We are early, and we would rather you heard that from us than worked it out later. We have not yet run a TSM perception survey for a social landlord. What we can show you today is an unedited recording of the AI conducting a survey call, the sample-size calculator, and a fixed price per completed response. If you need a supplier with a decade of housing references behind it, that is a fair reason to choose one.
What guides our work
Outcome-Focused
Success on a survey campaign is completed responses inside the accuracy band the Regulator requires — not features shipped.
Trust-First
We build for industries where trust matters. Privacy, transparency, and accountability are not features — they are foundations.
Your questionnaire, your programme
We run the fieldwork. The question wording, the routing and the sample design stay yours, and every call comes back transcribed so you can check the work.
Pragmatic Innovation
We apply AI where it genuinely solves problems, not for the sake of novelty. Practical utility over technological spectacle.
