Product Mastery Conference (SOLD OUT)

Meet other product people from across Europe and learn from thought leaders.

March 10th 2025 9:30 - 18:30 | Amsterdam

Wordline building - Neptunusstraat 41-63, 2132 JA Hoofddorp

What makes us different?

The product mastery conference was born from our personal network of about 200 product and tech leaders. In our own continuous discovery we’ve found that many of you are hungry for high quality in-person interactions with real product people. No window-dressing, no boring panels, no overwhelming size. Just quality sessions that you can immediately apply.

Max 150 people

When groups get too big the attention drifts and there a certain barrier starts to appear between audience and speaker/moderator. Therefore we keep our conference for product and tech leadersintimate with a hard max of 150 people, which we split into segments after the keynote.

Authentic stories

Ever been to a 'look at how cool I am' talk? Just shallow stories about successes? That is not our forte, we like to keep it real, so all our speakers will share authentic stories. Nothing is edited out, and everything is connected to real life examples on challenges most of recognize (impactful product strategy, effectively communicating with others, keeping your calendar under control, reality vs roadmap and more)

No Sponsors

You're here to learn, have fun, and connect with other product people. Sponsors distract from that. So we skipped them!

Featured Speakers

Marty Cagan

The one and only. Author of TRANSFORMED, EMPOWERED, and INSPIRED and partner at SVPG. His keynotes are thought provoking and his Q&As always yield good insights for the group. We’re super happy he agreed to come and give the keynote. Make sure you’re there!

Jason Knight

A well known influencer (although I doubt he would call himself that) Jason has seen many companies and is constantly contributing to the product community with his One Knight in Product Podcast and many posts on LinkedIn.This, combined with his down-to-earth and practical approach makes him a speaker you don’t want to miss!

Martijn Versteeg

Owner and founder of Group Effort, Martijn works with over 200 (product) leaders across Europe in over 20 peer groups. This conference was came from this networks need to connect in a new way. With his own background in growing and selling a Education Technology company and the many stories he gained from working across Europe, you’ll get some fresh practical perspectives on leadership and communication.

Ellen van Hemert

With over 10 years of experience as a product leader at Greetz and Drukwerkdeal, Ellen’s passionate about building great products, strong teams, and driving growth. Her session will share the uncensored story of how Drukwerkdeal scaled up experimentation, packed with actionable strategies you can apply immediately.

Steven Gillmann

Steven is an optimistic builder. Being in product for over 15 years now, he has seen many different flavours at the different companies he worked at (including Babbel, Kitchen Stories, and Bonial). His session will be about how he has implemented culture changes in product and he will share his never before shared Product Maturity Framework.

Willem-Jan Jansen

Some people seem to have all the knowledge, but non of the ego that usually comes with it. This is a pretty good start of describing Willem-Jan. Even though he is a true senior leader with big names like eBay and Marktplaats on his resume, he is still friendly and on the level with every product person he meets. He brings a joyful vibe but also has a ton of relevant experience he freely shares if you care to ask. His session will be about how to get rid of endless feature requests and roadmap battles by using practical steps you can start applying the next day.

Gertjan Dewaele

Gertjan will share the journey Wordline undertook. He will bring two team members for perspective. They will cover the politics, the coaching and processes they had to go through and learned from. There will be a Q&A where you get to ask individual contributors and a manager who went through this transformation about their experiences and lessons.
