Elsa Coleaux

Marketing Technology Lead at Treatwell

London, England Metropolitan Area

I love challenges, data, and people.

I’ve always loved challenges, the more complex, the better. I enjoy connecting the dots, working cross-functional to find creative solutions that generate value for the business. I’m driven, passionate, and never hesitate to roll up my sleeves to get the job done.

I taught myself SQL and Python to analyse data and build models to make the best possible decisions. Mastering these skills gave me a new direction in my career. I now use technology for digital marketing, mainly to scale, automate, and personalise but also efficiency and optimisation purposes such as revenue prediction or attribution model.

I had the opportunity to work with extremely different people and this has enabled me to open my mind to new ideas and perspectives. I truly care for people either the customers or my team and this has always been a source of motivation for me to go the extra mile.

Unusual facts about me:
- I smile when I run, many people think it’s creepy
- When I was 5 years old, I believed there was an underground network that enabled fax to be sent from point A to B.
- I can hold a plank for 5 minutes.
