About Rommil Santiago

How do you pronounce my name?

My name is Rommil (pronounced ROW-mill).

My motivation

I love connecting dots—and people—to explore new ideas and uncover better ways of doing things. I thrive on solving problems, taking on challenges, and building teams where talent can grow. I’m not afraid to take risks (at least in a business context), and I’m no stranger to ambiguity—it’s where I do my best work. In short, I just like to get things done, however I can.

Some things I’m proud of

At Loblaw, launching and scaling practices like Experimentation, Personalization, SEO, and Analytics Process Improvement from the ground up was no small feat—especially at a 100-year-old company.

I’ve also brought together teams across functions, countries, cultures, and time zones to align on growth. It wasn’t easy, but through persistence and collaboration, we overcame differences and started pulling in the same direction.

And of course, I’m proud to have authored the Amazon Canada bestseller Prove It or Lose It—a guide to helping Experimentation Program owners navigate the politics and realities of running experimentation at scale.

Recent jobs

I’m based in Toronto and most recently led Product Experimentation at Constant Contact. Before that, I led Go-To-Market Strategy for Experimentation Products at Optimizely, and served as Director of Growth Product at Loblaw Digital, where I oversaw Product-Led Growth, Experimentation, SEO, and Analytics Enablement.

Earlier in my career, I had the opportunity to work at startups like Ritual, 500px, theScore, and Flipp; enterprises such as Autodesk, CAE, and Bell; and institutions like McGill and Concordia Universities. Over the past 20 years, I’ve led functions spanning Marketing, Growth, Product, Analytics, and Customer Excellence. I even launched my own modest startup along the way.

My academic background

I hold a Bachelor’s degree in Mechanical Engineering from McGill University and an MBA in Marketing from Concordia University in Montreal. I’ve also taken many courses in design, analytics (from UBC / DAA), and photography.

My spare time

Outside of work, I run Experiment Nation, a global community of Conversion Rate Optimizers with well over 11,000 YouTube followers. I mentor CROs, product managers, and marketers, and I love sharing what I’ve learned to help others succeed.

When I’m not doing that, you’ll probably find me on a volleyball court—though my knees are starting to suggest I play too much.
