#GrowthTalks: Think Data with Rob W, Head of Data Science @ Travelbird

Heads up: the next Startup Maze Amsterdam meetup is on the 7th of December, from 6pm to 9:30PM. Make sure you reserve your spot today. 

Our special guest this time is Rob Winters, Head of Data Science @ Travel Bird. Rob tell us his experience with Cultivating Excellence in Data-Driven Organizations.

It has been repeatedly proven that organizations which put data central to their decision process are more effective, achieve better performance, and have better control of their risks.

However, it’s a common fallacy within companies that if they buy the right BI tool, data-driven decision making will follow. In this talk we will explore the experiences of building data-driven organizations in a variety of industries, the successes and failures, and some best practices to get an organization to “Think Data”.

Rob  has been leading data and analytics teams for over ten years in a variety of industries with a focus on “green field” and transformation projects. His primary focus has been on building the data technology, transforming organizations to be data driven, and developing machine learning/big data solutions to accelerate company growth.

In his current role as Head of Data Science at TravelBird he is responsible for leading the team responsible for Business Intelligence, Email/CRM, Data Warehousing, and Data Science.

Location & organization

This event will be hosted with the Help of our friends from The Thinking Hut. After the talk we will be able to buy some drinks from the bar and network some more.

Why imitating unicorns might not get you where you want.

We’ve all seen the mesmerising titles that promise us to reveal the best kept secrets of the startup unicorns. From Facebook to Uber, and from AirBnB to Instagram.

Every entrepreneurs wants to be like them and understand what’s their secret sauce. Of course media loves to capitalise on this trend.

In this podcast Nav and I give our opinions about how you should approach these lores, and I argue there’s little you can learn from them. I believe you shouldn’t try to apply the points they’re making ad litteram, but see how those can adapt to your specific case.

First of all, since they made it big, many things have changed and most of their lessons might be outdate. Besides, many of them capitalised on unique trends. They were at the right place, with the right product, with the right support, with the right money, with the … well you get the idea.

In his podcast I am joined by Nav Nouhi , an former colleague, a dear friend and data-oriented-no-bullshit-let’s-talk-numbers kind of guy.

I know Nav, from our AVG Technologies days, where as Director of Digital Advertising he managed $25M of advertising budget yielding 125% return on ad spend to the business and transformed AVG’s approach to digital advertising by pivoting to a LTV model.

He is currently a digital marketing  and growth adviser for early to mid stage startups, operating from the beautiful city of Prague.

When he’s not optimizing conversion funnels or creating digital acquisition strategies, you can find him skiing or cooking somewhere in Europe.

As always, I am curious about your opinion on the podcast. So please head to itunes or where ever  you might listen the show and give let us know what you think.

[Video] 7 Principles of Growth by Hoang Pham, Head of Growth @ Mollie

Two weeks ago I head the pleasure to have Hoang Pham, Head of Growth as a guest speaker at my StartupMaze Amsterdam meetup.

Hoang talked about the 7 Principles of Growth that help him structure and optimize the growth marketing backlog.

As an experiment, I used my gopro camera to record the video and recorded the sound on two other devices (which proved to be a great idea, becasue one of them stopped working) – then stitched it together.

Turns out the resulting video is better than I expected it. Thus, I think it makes sense to share it with everybody who missed Hoang’s talk.

[Video] How to improve your voice. Gain confidence. Nail public speaking.

Voice, that thing that comes out of your mouth. You know the one you feel awkward about when you hear yourself. It can be improved.

Linor Oren is here to tell us what good voice is and give us some tips on how improve your voice.

Linor is a voice coach with over 10 years of experience in opera singing and voice training. Through her sessions she helps people get in control of how they sound, gain confidence and get the right skills to own the room with their voice – which sound like things entrepreneurs would need to ace their public speaking events, startup pitches and even internal presentations. With that in mind I invited for a chat and thought I should record it and share it with you guys.


  • Drink water at least 3 hours before speaking. And a general rule you sound better if you vocal chords are hydrated.
  • Wrong posture can put pressure on your throat and makes you sound bad. Who knew?? Stay straight but relaxed. Search for Alexander technique. Linor swears by it.
  • Think of your voice like an instrument. Takes a bit of time to know how to play it and you can’t improve overnight. Takes a bit of Practice.

A bit about our guest.

Linor got her Bachelor of Arts in Voice and Opera from the Jerusalem Academy of Music and Dance. In  2010 she moved to Berlin where she performed as an opera and musical singer and performed on stages around the world. On the side she gave private lessons to people who were looking to improve their voice. Now she moved to Amsterdam where she primary focuses  on voice coaching.

You can find more about Linor on singwell.eu and on her youtube channel.

3 things a growth hacker needs to achieve exponential growth

A few days ago the founder of an early stage startup asked me if they should hire a “How do they call it, I’ve heard this term of growth hacker…”.

I told him that I think it’s too early for a growth hacker and that first they need to reach a product/market fit… but that question got me thinking. When does it make sense to hire a growth hacker? What other things should be considered?

Here are the 3 things, which I think, a growth hacker needs to achieve exponential growth.

Is there a product /market fit ?

Does the company make a product that people want? It doesn’t make sense to bring in a growth hacker before finding the product/market fit. A growth hacker can only scale things that work. Growth hacking acts as a magnifying glass, it can only increase the value if there is value to be increased.

Is there room for exponential growth?

The promise behind growth hacking is exponential/aggressive growth. That can be only achieved if there is room for exponential growth. In a mature market, with a well established product, that answers a well established need and has little to differentiate against the competition growth hacking won’t help. Growth is still possible. Sure. Exponential growth is not.

Is there Support?

Sure, a growth hacker is a “jack of all trades”, meaning that he needs to have marketing & communication experience, product owner skills, data driven approach, understand the product capabilities really well and the advocate customers needs.

However, he won’t be able to execute the plan all by himself. He will be able to identify the best actions and implement some of them by himself, but if he is to succeed, everyone in the company needs to understand that growth is the main focus at this stage and they should support the person leading the efforts.

Do you think I missed anything? Please let me know in the comments below. Really, if you think of something else please let me know.



Startup Consulting: What I’ve learned

Back in November 2015, I did a small experiment, I launched an open invitation to everybody in my network: get free advice for your startup from me.

The deal was: I would offer advice to people with projects in the pre-launch or early post-launch phase that would need help with their overall strategy, marketing, user acquisition, or product development… as long as I can use their cases as study cases for my blog.

Well, the time has come to share the things I’ve learned/found by doing this experiment. Here’s the summary:

  • 13 people contacted me
  • 7 people actually followed up/ qualified
  • 5 people got actionable advice from me
  • 1 launched me on a 2,5 month research into what it takes to achieve your goals

Curious about my little experiment, read on:

  1. People fall in love with their ideas and build products and services that nobody wants.

Even though I wrote about this in the past, it was different talk with someone going through this. Let me tell you about it.

I met Carmen, in December, for a cup of tea in Café de Jaren, here in Amsterdam. She told me that for the last year she built a consultancy and certification service, which would help companies become environmentally friendly.

She would certify restaurant and hotels, after they would take the courses she offered, apply the lessons and pass her inspection. She spent over 7 months building the program, the website, the courses and for the last 3 months she had been trying to sell it to the companies… but there was only one problem nobody wanted to buy what she was selling interested.

Not one restaurant or hotel saw the advantage of 1) helping creating this standard, or 2) being judged by someone. And of course nobody wanted to pay for such thing.

To her this came as a surprise. She loved the idea and thought it’s an amazing service. She put a year of her time, energy, and focus in this only to find out that the need she imagined for companies was not a real one.

As I mentioned, this happens quite often. But why? From what I can see, it’s because people fall in love with their ideas and don’t test them until it’s too late. So how do you find out if your startup idea is good?

  1. People love acquiring customers, but hate researching what they want

The other person I talked to was Adrian, of ASADRA. He is building a marketplace where independent designers around the world show their unique collections to people interested unique fashion.

I loved his enthusiasm and vision so I ended up investing the most time. I wrote about 7 pages of actionable advice and instructions on how to get more information about what their customers want.

We ended up not continuing our collaboration because I thought he should invest more time in understanding his customers, before moving forward while he wanted to start building personas… without talking to his potential first.

But that’s the beauty of doing work pro bono: you can stop as if you don’t agree with your client.

  1. People don’t work on their ideas

This, I found the most interesting. In fact I was so puzzled about it that that I spent a lot of time after figuring out how does one achieve his goals.

Let me tell you about it. Another person that asked for my advice was Sinziana. She wanted to marketplace where Romanian artisans, aka indie product designers, would promote and sell their creations to the people interested in unique local products.

At first my biggest question was how she would differentiate herself from existent websites, like etsy. But after a few minutes into our Skype call I found out that she was pondering taking action for about 3 years. She was talking with lots of enthusiasm and she could tell me how the website looks like, what products she envisioned, how she would advertise it, etc… but hadn’t done anything to start the project. So my question became why didn’t you do anything about it?

I found it puzzling. How come someone so enthusiastic about her ideas wouldn’t or couldn’t take action. I didn’t know what to say other than just take the first step.

But this made me realize I need to learn more about this topic. Especially since after the call I met more and more people at my Startup Maze meetups, who had the same problem. How else would I be able to help them out?


All in all, it was a fun experiment with a great deal of learning for me. I realize I am capable of giving valuable advice, but I do need to hone a few things. Interested in getting my feedback on your project, get in touch through the contact form.

IoT for startups: what is it + opportunities for entrepreneurs.

Heads up: the next Startup Maze meetup will be on the 19th of January. If you are in the neighbourhood you are more than welcome to come.

This time we will talk about what kind of opportunities does the new IoT network bring to entrepreneurs. I believe that the Internet of Things is here, and you have the chance to get in at the ground floor.

Amsterdam, Rotterdam and The Hague are already covered in a network that enables things to come online. And by July the entire country will be covered. What does this mean for your startup? What opportunities does it bring for you? Join us to find the why, what, how of the IoT movement.

Our speakers are two pioneers in this space:

Jonathan Carter is the initiator of the Amsterdam Internet of Things meetup (~2800 members), mentor at Startup Bootcamp, and co-founder of Glimworm Beacons (the first Dutch mass producer of iBeacon compatible sensors.)

Joahn Stokking is the Tech Lead at The Things Network, the first iot network that covers the entire of Amsterdam. He and Winke, just raised €300.000 on Kickstarter to crowdsource a global open and independent Internet Of Things network.

Hope to see you there. 😉
