Closer Consulting
Lisbon, Portugal
About
Closer Consulting is a Lisbon data science and AI consultancy working on machine learning, fraud and risk models and analytics platforms for banking, telecom, energy and retail clients.
Our Take
A 350-person consultancy whose banking work is substantial and entirely anonymous. Fraud detection at a major bank improved the true-positive rate on transaction flagging. Anomaly detection scrutinized more than 90,000 contracts to find revenue leaking through commissioning. A dynamic pricing system went into 700 branches of a commercial bank, updating price lists in real time against an estimated €230,000 of operating cost over five years.
The client roster is the mirror image: BBVA, Santander, Novobanco, NOS, Auchan, Leroy Merlin and Deloitte appear as names with no engagement attached to any of them. So the page gives you nine described systems with no client and twenty-two clients with no system, and the join between the two lists is the thing to ask for.
Alongside the services, an agnostic generative-AI framework is published as the firm's own accelerator for agent development.
Best for Iberian banks and insurers that need a supplier already fluent in their regulatory environment, and that will accept anonymized references in exchange for scale.
Key strengths
- The described work is operational rather than exploratory: fraud true-positive rate, anomaly detection across more than 90,000 contracts, pricing rolled out to 700 branches
- One engagement carries a costed result—roughly €230,000 of operating cost over five years on the branch pricing system
- A 350-person bench with its own generative-AI framework for agent development, and a client list running to BBVA, Santander and Novobanco
Good to know
- Every case study is anonymized by sector while every client is named without an engagement—ask which of the named institutions the described systems belong to
- Only one result carries a figure; ask for the fraud detection lift and the leakage recovered in numbers
- No rate, no team page and no named practitioners—ask who leads delivery and how much of the 350 would be on your engagement
