The Challenge

Kalgera's AI-driven early warning system detects financial vulnerability through transaction data signals. Before scaling the product, Kalgera needed primary qualitative research to validate that the signals reflect real lived experiences — not just statistical artefacts. The work was delivered within the regulatory context established by the FCA Consumer Duty, which places explicit obligations on firms to understand the needs of customers in vulnerable circumstances, and the Financial Conduct Authority's Guidance for Firms on the Fair Treatment of Vulnerable Customers (FG21/1).

The research had to capture the experiences of financially vulnerable adults in Scotland: people experiencing cognitive decline, scam victims, carers managing money on behalf of others. Reaching this population ethically and reliably required specialist recruitment and a robust ethical framework aligned with the Adult Support and Protection (Scotland) Act 2007. NHS England's framework for inclusion research and the Office for National Statistics guidance on surveying vulnerable populations informed the recruitment and consent protocols. Fintech Scotland, in partnership with the Scottish Government's Financial Health Lab, supported access to the target participant cohort.

Research Programme — Three Stages

StageMethodDetail
1Paid Social RecruitmentFacebook and Instagram campaigns. Primary target: financially vulnerable adults in Scotland (50+). Secondary: 35–49 age group.
2Screening Survey80–120 respondents. Quantitative and qualitative data. Qualification criteria mapped to Kalgera signal categories.
3In-Depth 1:1 Interviews8–10 interviews, 60 minutes each. Semi-structured protocol mapped directly to all eight signal categories.

Kalgera Signal Categories — Interview Protocol

Each interview was structured around all eight of Kalgera's signal categories. Participants were asked to describe experiences relevant to each category in their own words.

Signal CategoryWhat it captures
Spending pattern changesSudden shifts in regular spending behaviour.
Income depletionFaster-than-expected drawdown of available funds.
Credit relianceIncreased use of overdraft, credit cards, or BNPL.
New payeesPayments to previously unseen accounts.
Cash patternsUnusual ATM withdrawal frequency or amounts.
Bill changesMissed direct debits or new recurring charges.
Account accessLogin frequency, timing, or device anomalies.
Scam indicatorsTransaction patterns consistent with known fraud typologies.

Ethical Framework

  • Framework aligned with the Adult Support and Protection (Scotland) Act 2007, ensuring duty-of-care obligations were met throughout the research programme.
  • Distress protocol in place with trained facilitators for all interviews, consistent with NHS England inclusion research standards for research involving adults at risk.
  • All data encrypted, UK-hosted, and anonymised within 7 days of collection. Data handling aligned with UK AI Safety Institute guidance on responsible data use in AI validation research and Cabinet Office data security classification requirements.
  • Verbal and written consent obtained for participation, recording, and data use. Consent process reviewed against Office for National Statistics ethical standards for qualitative social research.

"Qualitative research with financially vulnerable adults requires the same rigour as clinical trials — distress protocols, ethical oversight, and a methodology grounded in lived experience. The Adult Support and Protection (Scotland) Act 2007 framework we built gave Kalgera's signal validation genuine human validity."

Output 2

Intervention Acceptability Framework

Documents what vulnerable people consider helpful versus intrusive. Defines the acceptability spectrum for AI-driven nudges.

Output 3

Summary Findings Report

Condensed findings for the Finance and Health Lab. Direct participant quotes used to support product decisions.
