I’ve been in love with building businesses since 2011.

Now, with a passion for endurance, I aim to strive on ultra distances while occasionally coaching trail runners.

Entrepreneur.

My "main gig" is working as a co-founder on Kitchn.io. We are building a SaaS startup at the intersection of no-code and MarTech, so I'm dedicating most of my time to learning about growing our business and marketing and selling our software. I have co-founded and invested in several businesses before: I ran my own door-to-door selling business in California, built arbitrage advertising tech company Bertbaum Internet, spun off Tante-E, angel invested in Nuri for Babies, GetPacked and Beelinguapp.

I currently do not invest as an angel investor and put my full entrepreneurial focus on growing Kitchn.io. Follow me on Twitter and our company’s Youtube to follow along our journey.

Ultra-endurance Athlete.

Although being a football goal keeper for all of my teens & adulthood, I was always a surprisingly good runner. In late ‘21, after having done a few shorter triathlons and 10k races, I decided to take things more seriously and ran my first trail marathon at La Corsa della Bora in January of 2022. Since then, I’ve completed several trail marathons since and ran my first 100k at Laufhaus Backyard Ultra in July ‘22 as well as finishing my first Ironman 70.3 at Erkner in September ‘22 and first Ironman in June ‘23 in Austria.

Aspiring Trail Running Coach.

As a business leader in the last 10+ years, I’ve always thoroughly enjoyed the 1:1 work with my colleagues and help them develop and acquire skill and knowledge. By learning how to race ultra-endurance myself, I started to put together an extensive library of knowledge from various sports. Bringing those together, I started coaching beginners to prepare them for trail races and increase aerobic fitness. I am also a certified Ultrarunning Coach from UESCA under Jason Koop.

As I have a full-time job, I currently only work with a couple of clients at the same time. If you want to get involved whenever a slot opens up in the future, send an e-mail to coaching@martinkreienbaum.com.
