Why Growth?

As Paul Graham eloquently put it, “Startups = Growth.”  While he was referring to the growth of a startup’s customers, I believe startups are also one of the best vehicles to maximize the growth of people.  It pushes your limits, forces you to think about things you otherwise wouldn’t, and surrounds yourself with some of the smartest and motivated people out there.  

I have primarily expressed my passion for growth through my concentration on the intersection of product and user/customer acquisition.  But I am also fascinated with how to grow teams, processes, cultures, and most importantly people (including myself).  

Professional Background

I'm currently the Founder/CEO at Reforge.  Before that I was VP of Growth at Hubspot working on new product initiatives such as the HubSpot Sales products. 

I’ve been a co-founder of 4 companies in the past 10 years, 2 VC backed, 1 angel backed, 1 bootstrapped. 2 acquired, 1 shut down, 1 TBD. I’m currently focused on finding the next company I want to build.  In the meantime I am consulting and advising a few select companies on growth. On this site you will you will notice I don't post as often as others (typically once a month).  That is because I prefer to focus on quality and uniqueness over quantity.  The best way to make sure you don't miss my posts is to subscribe to my newsletter

I advise companies on a selective basis.  I've been in the founder seat and want to make sure I can a lot of value.  I can add the most value if you have reached just started to reach product market fit and are ready to put a formal growth process and machine in place.  If interested please email me (info at the top of this page).   

Personal Background

Give me a University of Michigan Football game, a Bud Light (don’t judge), and some BBQ and I couldn’t be happier.  I’m a classic midwesterner, born and raised in Michigan, and a Sports Business, Statistics, and Economics alumni of the University of Michigan.  While I am based in San Francisco you will often find me in LA, Chicago, Boston, and Michigan spending time with friends and other entrepreneurs.
