Siem Reap's Leading Digital Marketing Agency

About Olive & Lake

Olive & Lake was born out of a collaboration between Sebastien Olive and William Lake. They met after Sebastien was looking for somebody to help with digital marketing for the company he was working for at the time.

William had been working as a freelance digital marketer for many years and was recommended to Sebastien. In spite of their “Anglo-French” rivalry and disagreement about whether it’s called the “English Channel” or the so-called “La Manche”, William started working with Sebastien on a new project for the Embassy Restaurant in Siem Reap.

The project was a tremendous success. Together, they turned around the fortunes of the online side of the business.

Sebastien then commissioned William to work with him on 14 other successful projects with similar outcomes.

The two had an idea for their own website project and Olive & Lake grew from there. Both William and Sebastien had complementary skills and thought that they would work well together. The beginnings of creating a digital marketing agency were born.

New Website

For years William didn’t have time to make his own website, he was too busy working on his client’s projects.

Finally, Sebastien sat him down and said “enough is enough, we need a new website.”

So we made one and it went live today! It’s a simple website, just a one pager, but within weeks, it was ranking highly in Google for all their main keywords.

Price Parity Checker

We developed a tool to help us save a lot of time. Our revenue management officers were spending nearly 50% of their time manually checking prices for our clients.

This had to stop.

We developed an in-house tool to automate this entire process.

It was a triumphant success and moved us to the next level of increased visibility across all sales channels.

Today, we decided to make it public.
