// About

An advisory practice at the intersection of finance, operations, and data.

Galois & Co. is an independent advisory firm working with technology-driven companies, institutional clients, and venture-backed teams. We combine the rigour of investment banking with the practicality of modern data engineering to help clients make better decisions, build better systems, and execute with clarity.

// 01. Name

The story behind the name

The firm is named after Évariste Galois, a young and largely self-taught French mathematician who, before the age of twenty-one, founded what we now call group theory. Rejected by the establishment of his time and dismissed by his peers, he transcended the limits of what he was supposed to be capable of through sheer intellectual curiosity and a refusal to accept inherited boundaries.

We chose the name because it captures a posture we try to keep. Treat every problem as if there is a simpler structure underneath, and have the curiosity to look for it, whether the surface is a financial model, an operational workflow, or a tangle of unstructured data.

Don't cry, I need all my courage to die at twenty. Évariste Galois, 1832

// 02. Approach

How we work

Most advisory firms promise breadth. We choose to be specific. Our work sits at the precise intersection of three disciplines. Investment banking, where we know how a deal closes, how a P&L is built, and how a back office actually operates. Operations, where we have built reporting frameworks, automation systems, and process governance for institutional clients. And data engineering, where we design the pipelines, dashboards, and machine learning tools that turn raw data into decisions.

Because we work at this intersection, we are most useful to clients who need someone fluent in both the financial and the technical sides of the table. Founders preparing a raise, finance teams modernising their reporting, venture firms building operational leverage, or institutions running a transformation project.
