Finance
We turn customer behaviour and process data into analytical decisions.
Financial institutions are rarely short of data. The hard part is deciding which question to ask.
Defining the decision first
We start by defining the decision itself: which customer, through which channel, with which offer? Models built before that question is settled tend to work well and go unused.
Where we work
Customer segmentation and behavioural modelling. Grouping customers by what they are likely to do next rather than by what they have done.
Channel and campaign effectiveness. Measuring what a campaign actually produced, after filtering out the transactions that would have happened anyway.
Process and operations analytics. Making visible where operational processes stall and how long each step takes.
Reporting infrastructure. A reporting layer where a number can be traced and its refresh time is known.
Data sensitivity
In finance, data is as sensitive as it is plentiful. In the structures we build, where personal data sits, at which layer it is masked and who can reach it are defined upfront. Regulation requires this too, but we would do it anyway as a matter of good engineering.

Kuveyt Türk
Kuveyt Türk: master–apprentice mentoring for the Digital Marketing and Retail Customer Analytics teams
It began in 2023 with SQL, Power BI, Python and machine learning training for Digital Marketing's analytics team. The team then built its own projects under Lumtify's mentoring: digital score, target management, churn cause analysis, UI usage analysis, product recommendation and churn prediction models. Since 2025 the work has continued with the Retail Customer Analytics team on spending analytics, a luxury spend score and next-best-action prioritisation. The team writes the code; Lumtify sets direction, brings the method and checks the output.

Türkiye Finans Participation Bank
Türkiye Finans: training and project mentoring for the HR analytics team
In 2024 we spent one day a week with the participation bank's HR Analytics team: first Python and machine learning training, then mentoring on the team's own projects. The relationship between the recruitment assessment inventory and performance and retention was analysed by job family, and a literature review and model design were done for employee attrition prediction. The team applied what it learned to the institution's own data straight away.
