Incoming Consultant, McKinsey Digital — MBA, INSEAD Class of 2025

Seven years turning ambiguous data into decisions boards act on — a DCF model that shaped an acquisition, a renewal-prediction model that added $1.3M ARR a quarter, and a geo-strategy that unlocked $10M a month in revenue.

About

Left brain runs the models.
Right brain runs the fast break.

I'm a data & analytics leader turned incoming consultant — I've spent seven years building the models companies bet decisions on, and just as long leading teams off the spreadsheet: on a basketball court, on an athletics track, and in a mentoring circle.

Left brain

Data, strategy & scale

Leadership, beyond the desk

President of the INSEAD Basketball Club and captain of DTU's athletics team — 36 medals across three varsity tournaments. Co-founded a mentoring society that placed 60% of its juniors within a month, and I still show up for the team huddle.
