A founder has three core tasks: to set the vision of the company; to build the team that is going to deliver on this vision; and to secure the required resources for the team to make it happen. We want to make sure that you perform on all three tasks in the best way possible.


We lead seed rounds by investing an amount of €1M to €1,5M in exchange for 15-20% of equity. We offer industry-standard, founder-friendly terms. We follow up to maintain our pro-rata in Series A and Series B rounds.


We help you build an employer brand and hire amazing people. We maintain a good overview of the available talent pool in our community and assist you in finding the best.

Marathon has helped us in any way possible. They have been the best recruiter we have.

Great companies are well-run companies. We help you set up shop, run a proper operation, and establish a level of compliance that makes certain you will shine in future due diligence.


We have built an understanding of what it takes for a seed stage company to get to the next level. We help you build your product and go-to-market strategy, making sure that you invest your time and assets on what's important.

Marathon helped us along the way even with product strategy & marketing posts.

We have co-invested with some of the best funds in the world. We measure our success by the caliber of your next investors, who will help us take your company to the next level. We will figure out who you should be talking to, introduce you to them, and make sure you are well-prepared. As long as the company performs well, we make sure future fundraising is well taken care of.


Success in the startup world requires access to an extensive network of people: top talent, key executives, trusted advisors, forward-thinking customers, experienced board members, world-class investors. We could not be more proud of the network we have built and we are excited to make you a part of it.


Entrepreneurship is said to be a lonely journey. It does not have to be such. First and foremost, we build transparent, sincere, and long-lasting relationships. We exist to be the first you turn to for a word of advice or even emotional support.

The greatest contribution of Marathon is the time they spend with you.
