Build your idea in 42 days
Join the waitlist to stay up to date and get a front-row seat to the pilot season
DAY42 is a 6-week online program to get your idea off the shelf 🚀
During our free program of 42 days, we are streaming interactive lessons, sharing knowledge from experienced founders, discussing your ideas and building together.
Are you waiting for your idea to happen?
You are not the only one. Just like ourselves and thousands of other Europeans we face the struggle of postponing. With the DAY42 program we will help you to Build in Public and launch every week ⚡️

But... I don't have a good idea
Relax, there is always something you can work on. It could literally be anything, but you have to commit solving a problem. During the program we will help with idea generation 💪

Thousands of European creatives hold back on their ideas...
Which is a big waste of talent. Just to realise there has never been a time with so much possibilities to bring your own ideas to life. You are the only one holding you back... and we’re here to change that. Join the waitlist and start building.

Questions?
Here are some answers that might help. Get in touch here for sponsorships, partnerships or other related questions.
YES! Our program is doable next to your existing study or job. As long as you are willing to put in the time and unlock your potential, you should definately apply.
We want to make the DAY42 program available to anyone who is excited to build something, regardless of their financial situation. Therefore, the program is entirely free.
Our first program runs on partnerships and sponsoring. Looking to connect or do you want to request a meeting? Sent us an e-mail to day42co@gmail.com or schedule a meeting.
No, not yet. We have a great outline, and we want to test it during our Pilot Season! Are you one of the first participants? Sign up for the waitlist.
You don’t need a fully-formed idea to join DAY42. But having a rough sense of the problem you want to tackle helps for sure. We will help to shape your idea. PS: If your idea changes overnight: no worries - just pivot.
The full program will be announced shortly on this website, but one thing is for sure: it will be awesome and you will not build alone.
These six weeks are the perfect amount of time to make real progress without overwhelming your schedule. It's long enough to launch something meaningful, yet short enough to keep you focused and energized. Think of it as a sprint, not a marathon. While you can move faster or even pivot during the program, the live class schedule will remain fixed.
DAY42 is for the builders and the dreamers. We are the no bs place for building and hacking. So if you are running around often with ideas in your head but just don’t find the right moment to start properly working on it? This is your moment.
No. We don’t do mentoring or coaching. We give short and concise lessons during livestreams so you learn live, chat & connect with other participants whilst building on your idea. We give you the tools and lessons that we learned from our own personal experience in hacking and building. It’s time to cut away all the bs and just start working on your ideas.
