2011

Roots – Google Dublin

Founding Hide and Seek

During their time at Google they realised there was a need for a new, a different, a more customer focused online agency. An agency, that would always put the customers first. That’s why they founded Hide and Seek in January 2014.

Our approach

1
Get to know all the ins and outs of the customer. The more you know the customer and its audiences, the bigger chances of success.
2
Every customer is different, and therefore needs a custom made strategy. There is no such thing as ‘one size fits all’.
3
Select the right services, channels and formats that fit best with the products, messaging and audiences.
4
Optimise, expand, innovate, communicate, strategise and start again with step 1, it’s a never ending story.

Why Hide and seek?

 

Knowledgeable

The knowledgeable online advertising agency. Online advertising is not something that can be learned from a theory book. It is a continuous process of trial and error, innovation and testing. That is what we do. Continue until we find out what works best in every different case.

 

 

Strategic

The strategic online advertising agency. We never simply do what our customers ask us to do. We always start with taking a few steps back. This way, making sure that what we plan to do is exactly what it is the customer wants us to do.

 

Personal

The personal online advertising agency. We see ourselves as one team with our customers, sharing the same objectives. That’s why we always involve our customers, communicate closely with our customers and make sure we are fully transparent in everything we do.

 

 

Different

The different online advertising agency. We do not stick to a so-called normal. We do not have strict times, deadlines, means of communications. We just stick to ourselves and of course… to our customers. Just like us, our customers are always different too.

Sabine Roex

Co-Founder

Sabine in three words: energy – honest – human.

Late 2013 Erik came with the idea to start an advertising agency. During our time at Google we both worked with many different online agencies, but not one worked in a way that we considered top-notch. So why not do it ourselves? I did not need to think long and now it is already more than five years later. Within Hide and Seek I focus on the organization of our team, I keep myself busy with new customers, I maintain relationships with existing customers and I also now and then manage a campaign myself. Every day finding new and better ways to reach our customers’ audiences continuous to fascinate me. Playing the game and outsmart competition. But certainly, also knowing out customers through and through, ensuring a great relationship for both sides and thus being strong together. This is what makes me tick and gives me the energy to every day push ourselves to be even better. All of this together with our great team, which I am very proud of.

Julian Jenner

Account Manager

Julian in three words: approachable - to the point - cheerful

One of the firsts to join the Hide and seek team in October 2014. In these years I've gained a lot of knowledge and experience in the field of online marketing. My specialization is focused on display marketing (Google Display Network) and social marketing (Facebook, Instagram & Snapchat). However, I've also gained quite some experience with Google marketing products (Analytics, Tagmanager, SEA/ Search ads, YouTube/ Video ads, Gmail & Product list advertising/ Shopping). I am also quite familiar with advertising on the LinkedIn network! Because of my broad knowledge, I am able to provide effective and fully customized online marketing strategies for my clients and execute them properly. My strong ability to empathize with any target audience helps me to reach them perfectly with advanced targeting and high-profile advertisements.
Besides Hide and seek I like to travel a lot - especially European city trips to meet up with all of my friends. When I am not traveling, chances are that I can be found either at the gym - or when I am lazy - on my couch to binge watch on Netflix. Either way, my friends and family play a big role in all these activities!

Arnoul De Wit

Account Manager

Arnoul in three words: multitasker - relaxed - no nonsense

I grew up in a 'small' city near Rotterdam. After studying in Utrecht for a while, I started and finished my Media study in Rotterdam. During my study, I became active in organising events and working as a self-employed marketer. After finishing my study I worked on several marketing positions at different companies before fully focussing on online marketing.
After working at several companies I wanted to work at the agency side of digital marketing, so I could have a diverse portfolio of clients and work on multiple projects. In March 2016 I started working at Hide and Seek in Amsterdam and I enjoyed it ever since.
When I am not working I enjoy good food and drinks and having fun with friends, listening to music, going to the cinema and playing some occasional sports.

Rosanne Koet

Office Manager

Rosanne in three words: Colorful - Spontaneous - Service oriented

Hide and Seek consists of a young and enthusiastic team that I love to be part of. My job is to connect all the internal dots and make sure the back office is in order. I'm less directly connected to online marketing, however, I do notice my interest has started to increase slowly but steadily. Online marketing is inseparable from the future and to be able to learn about this within the company, is a great opportunity. Hide and Seek is constantly on the move and I like going with their flow!
Besides Hide and Seek I am passionate about traveling to discover new cultures, people and natural wonders. When I'm at home, I play the piano a lot and organize dinners for friends on a regular basis. I would like to be able to speak all the languages in the world. If I could only communicate freely with everyone without any barrier, would be a dream come true.

Jamie van der Poel

Account Manager

Jamie in three words: Sporty - Go-getter - Friendly

In december 2018, I joined the young and enthusiastic team of Hide and Seek. As account manager I am loving all the online marketing aspects. At Hide and Seek I can learn a lot about this, and I find this very fun and interesting.
Besides Hide and seek I am playing in a handball team as a goalkeeper. I am also passionate about traveling and love to take pictures of the architecture and the culture. If I would get the opportunity to make my dreams come true, I would go to Australia. I would love to see the nature and to spot the kangaroos.

Mayke Koks

Account Manager

Mayke in three words: Sporty – Enthusiastic – Enterprising.

At Hide and Seek, every of my work day starts with a bunch of enthusiasm. With a young, small and energetic team we make sure to go that extra mile. Despite the fact that each of us has a specific client portfolio, there always is a solid and friendly teamspirit that keeps us going.

Shortly after my graduation, I started working at Hide and Seek as a junior account manager. My expertise within online marketing? That voyage of discovery is still going strong. Within the company there is a lot of room to develop and learn, which is very challenging! One thing is for sure, creativity is a big interest of mine. In my spare time, when I leave the Hide and Seek office, I like to discover the world by travelling, host dinners, do fun activities with friends and love to be active in the gym.

Gabriël Can

Account Manager

Gabriel in three words: sociable - empathic - easygoing.

Born in the east of the Netherlands, I’m living in Amsterdam for almost a decade now. After my BA studies in Advertising, Marketing and Communications, I have worked as a social media- and e-mailmarketer for JACK & JONES and de Bijenkorf. Here I was partly responsible for coming up with, coordinating and the executing creative campaigns and strategies. This is where I first got my hands on the basics of Facebook Advertising. I also have worked as a personal stylist in between.

At Hide & Seek I am able to let my creative side speak in my role as junior account manager, as well as my analytic/communicative abilities. Every day I get the chance to learn the new tricks of the trade of online marketing and execute them for a very cool and impressive portfolio of clients.

My weekends often consist of a party with friends but I also enjoy to hunt for new coffee-spots in Amsterdam, travel the world and (unfortunately) shopping also really relaxes me.

Loes Schellekens

Back end Developer

Loes in three words - Curious, creative and a thinker.

I started as an intern, but now I am an official employee at Hide and Seek! I assume that they were very satisfied with my work during my internship! This year is the final year of my International Business degree. During my internship I learned that online marketing is one of my interests. I would like to continue my career in this direction after my education. Currently, I am working on a new project for Hide and Seek, which will come to light pretty soon.

In addition to working at Hide and Seek, I like to spend my time on video games, reading, and writing. And of course spending time with my boyfriend, friends, and family!

Levi Jansen

Intern

Spontaneous guy from the middle of the country who got lucky with an internship at Hide and Seek. Levi is conducting a research about a new project Hide and Seek will launch this summer. This will enable the company to make better, fact-based, strategic choices and will enable me to graduate. In the past I have worked as a waiter and bartender for several restaurants. Last year I have worked on SEO strategies in different markets, which was fun.
Next to graduating I am currently working as a junior account manager at Flyerman. Also, I love to play football, lifting weights, go to festivals and make music all day. Eventually, I hope to produce an advisory report that gives Hide and Seek more clarity on choices that are to be made concerning the strategy for the new project.

Kelly Geerlings

Account Manager

Kelly in 3 words: Adventurous - Sincere - Sporty

About 8 years ago I moved to Amsterdam from the south of the country. Initially, for my Masters in Marketing at VU University Amsterdam, I enjoyed staying in the big city after my studies. After my first job in 'offline' marketing as category manager magazines, I switched to the world of online. I gained my first knowledge at an agency specialized in online fitness marketing. Hide and Seek is the second agency where I have the pleasure of working. Here I can broaden and deepen my knowledge. I do this every day with great pleasure while I work for the coolest customers. Besides work, I love to travel the world, visit music festivals, get sweaty with different kinds of workouts and is watching reality-tv my favorite guilty pleasure!

Jurriaan Bastinck

Account Manager

Jurriaan in 3 words: Reflecting - Loyal - Analytical

Hi! My name is Jurriaan and I’m a real import Amsterdammer, for almost 3 years now already. Time flies when you’re having fun I guess! After finishing a Bachelor in Rotterdam which in the end wasn’t really for me, I decided to follow my gut feeling and started a masters in Persuasive Communication at the University of Amsterdam. The best choice that I could have made! During the masters I developed an interest in marketing in the broadest sense of the word, but especially the topic of cognitive biases; judgemental errors in our thinking.

Anyway! The move from Rotterdam to Amsterdam didn’t go unnoticed with my friends in Rotterdam (the football rivalry and all). Luckily I have been able to settle quite well in Amsterdam, especially since I have joined Hide and Seek. After a month I already felt at home and it was as if i’ve entered the cirkle of trust. After a bunch of relevant theoretical knowledge and a year of work experience in the sales/marketing spheres I’m glad to have found something in which I’m willing to develop myself further and learn more about. Luckily this the place to do just that, so they’re going to be stuck with me for a while longer! In my weekends I frequently make the trip back to my hometown in the countryside to get away from the big city for a while. Furthermore, I’m passionate about discovering new cultures and new things in general as well as snowboarding!

Hannes de Spiegelaere

Account Manager

Hannes in three words: Sporty, honest & inquisitive

I was born in Ghent (Belgium) and have been living in Deinze my whole life. Since August 2019 I live in Amsterdam, together with my girlfriend.

After studying Graphic & Digital Media and Digital Marketing & Communication, I started as an online marketer at MonkeyProof, a digital agency in Belgium.
There I was part of the ‘agency-team’ and mostly focused on Facebook ads and Google Search Advertising. Furthermore, I frequently made use of LinkedIn Advertising, Instagram Advertising, Google Analytics and Google Display Advertising.
At Hide & Seek, I hope to increase my knowledge of these specific tools and improve my online marketing skills.

In my spare time, I sport regularly. I am especially interested in football; you could say I am a football addict 🙂. I have been playing football since I was 5 years old and, during the weekend, I watch several games on television. Finally, I am also a family man: the most important people in life are my family. Therefore, I take enough time to meet up with friends & family. Thus, from time to time, I will undertake the trip from Amsterdam to Belgium.
