entrepreneur. investor. executive. 

Hi, I'm Zephrin (yes my parent's really made up my name).

I like to build stuff, grow stuff and occasionally break stuff. I like small teams that get along but still challenge each other.

I invest in startups. I'm working with an amazing set of entrepreneurs on some great companies. I also consult for companies on their products.

I believe that product is first and foremost a creative endeavor --- and that having a clear vision and doing one thing greatly beats tons of features and endless requirements.

My latest company is called ShopChat [update: we've been acquired]. Now I'm at Rakuten Viber integrating our tech and team as Head of Ecommerce. We are building a new kind of commerce. Stay tuned.

I've built companies from raw ideas into global disruptors, and worked in big companies with dizzying numbers of moving parts. I've had great days and dark ones too. I co-founded and was CEO of Pontiflex. I am also the Chairman of Sickweather and an Advisor to Contactually and Browseplay. I was Head of Mobile and Social Product at Constant Contact at the time of our acquisition by EIGI for $1.1BN. I did lots of other weird stuff in NYC, Prague and London. I wasn't born in the US.

I used to be the #3 search result for "man" on Google Images. Well at least I was at the beginning of 2016. So if you see my picture somewhere strange, it's not me. Really.
