Startups/companies/what-have-you

I started lots of stuff. Some of it worked, some of it didn’t. I’m not done yet!

DailyCrunch

Automatically sync your Pocket and Instapaper articles as daily magazines for the Kindle. Apparently not a lot of people read non-books on their Kindles, so I finally shut this down in 2017.

Novelo

A Facebook commerce platform. Startup Chile Alumni (1st batch), shut down in 2012.

BlooBox

A Wordpress-like platform for Digital Signage. Acquired in 2011.

InvestidorVirtual

A stock market simulation game that reached 25,000 very active users (deactivated in 2009 due to “regulatory costs” aka Bovespa didn’t like the competition).

A mapping service that allows users to set up their own Google Maps-based guestbooks and embed the maps on their own websites, reaching 45,000+ regular users. Deactivated in 2015 due to payments and API issues.

Sollipsis Interactive

Selling mobile games. In Brazil. In 2003. Perfect timing!

Connect

My first company (founded 2001). Focused on PalmOS software and sales force automation. Company still lives on!
