Somebody should be listening when it matters most.

We build real-time intelligence for regulated customer conversations, so that the people least able to ask for help are the ones most certain to be heard.

Most contact centres check fewer than two calls in a hundred for signs that a customer is struggling. Regulation now expects every case to be found, supported and evidenced. That distance is the whole of our work.

What we build
01

Nothing is sampled. Everything is heard.

Every conversation is analysed as it happens, not a chosen few after the fact. There is no sampling gap for a vulnerable customer to fall through, because there is no sample.

02

The judgement stays human.

Our software never decides anything about a customer. It notices, it tells the agent what it noticed, and it recommends what your own vulnerability policy says to do next. The person on the call decides. Always.

03

Proof, written as it happens.

Every flagged conversation leaves behind a complete record: what was detected, what was said, what consent was given, what support was offered. When a regulator asks how you treated someone, the answer takes a moment rather than a month.

04

The next call never happens.

When a customer is confirmed as vulnerable, Sentinel says so to your dialler and CRM in a form they can act on: take this account out of the campaign, route it to the specialist team, do not auto-dial. Someone who has just told an agent they are struggling is not rung again on Tuesday about the same debt. That is where the cost of a repeat call, and the distress of it, both stop.

Our first product

Sentinel

Sentinel listens alongside a live call, recognises the signs that someone is in difficulty as they surface, and puts that in front of the agent while the conversation is still happening. By the time the call ends, the evidence pack has already written itself.

  • Vulnerability signals scored continuously, first word to last
  • Guidance to the agent in the moment, drawn from your own policy
  • An FCA Consumer Duty evidence pack for every flagged call
  • A disposition signal to your dialler and CRM, so a flagged customer is not called again by a campaign
  • Built so that a person, never the software, makes the decision

Not agent assist. Not QA scoring. Not sales flagging. One job, done during the call.

Generated automatically during the call. Confirmed by the agent before filing.

We are looking for three firms willing to build this with us.

Design partners shape what Sentinel becomes. It costs nothing, it starts with no customer data whatsoever, and it only goes further as trust does.

Weeks one to two
Realistic scripted calls, mirroring your own. No customer data, no integration, nothing for legal to review.
Weeks three to ten
A sample of your real recorded calls, under a signed agreement. Transcripts only, processed in the UK and EU.
What we ask
A named contact, a couple of hours a week, and a reference if we earn one.
What follows
First refusal on a paid pilot, at founding partner terms.
Questions we get asked

What is Sentinel?

Sentinel is real-time vulnerability detection software for regulated contact centres. It listens alongside live customer calls, identifies signals that a customer is in difficulty as they emerge, prompts the agent during the call, and generates an FCA Consumer Duty evidence pack automatically.

How does it support FCA Consumer Duty?

Consumer Duty requires firms to identify customers in vulnerable circumstances and evidence that they were treated fairly. Sentinel supports both: it scores every call rather than a sampled subset, and produces a timestamped record of what was detected, what consent was captured, what support was offered and what happens next. Compliance itself remains the responsibility of the regulated firm.

Does the AI make decisions about customers?

No. Sentinel never classifies a customer, denies a service, or takes action on its own. It surfaces what it detected and recommends next steps drawn from your own vulnerability policy. The agent on the call decides and acts. That is deliberate, because decisions about vulnerable people should not be automated.

What data does it process, and where?

Call audio, a live transcript, the vulnerability signals detected, and the evidence note the agent confirms at the end. Sentinel acts as a data processor on your documented instructions and you remain the controller. Processing and storage take place in the UK and EU. We keep the transcript, not the recording: audio is transcribed and then discarded, and recordings stay on your own telephony platform.

What happens after a call is flagged?

Two things. The evidence pack is generated for the compliance record, and a disposition signal goes to your dialler and CRM: suppress this account from outbound campaigns, route it to the specialist team, do not auto-dial. Without that signal, a vulnerable customer wrapped with the wrong code stays in the campaign and gets called again, which means more distress for them and the cost of a repeat call covering old ground for you. Sentinel publishes the signal as a structured event. Your own systems consume it.

Is it an agent assist or QA scoring tool?

No. Sentinel is not general agent assist, not QA scoring, and not sales or opportunity flagging. It does one thing: it finds vulnerability while the call is live, acts on it before the next call, and evidences it before the agent hangs up. That narrowness is deliberate.

How is it tested for bias?

At two separate layers. First, speech recognition accuracy across regional accents, non-native English speakers, older voices and speech differences, because a degraded transcript degrades everything after it. Second, detection accuracy on clean transcripts, to isolate the classification itself. We treat under-detection as the graver harm, because a missed signal means somebody who needed help did not get it. This is our published testing method. Results go to design partners as a one-page fairness summary alongside the security overview.

How many calls does it review?

All of them. Manual quality assurance in most contact centres reviews fewer than two percent of calls for vulnerability, and finds problems weeks after the conversation that mattered. Sentinel scores every call as it happens, without adding anybody to the floor.

Who is it built for?

FCA-regulated firms running contact centres: debt collection agencies, consumer lenders, banks, energy utilities, and the outsourcers who run collections and servicing on their behalf. United Kingdom first, with the equivalent regimes in Ireland, Germany, France, the Netherlands and Spain to follow.

Can I try it?

Yes. The live demo runs on simulated call data with no real customer information. We are also taking on three design partners, and the first phase uses realistic scripted scenarios with no customer data and no integration, so your compliance team can look at it without needing a data protection review first. Running Sentinel on your own recorded calls happens inside that programme under a signed agreement, not through a public upload.
