Ruben is the founder of Bidsketch, a bootstrapped SaaS app that’s used by thousands of freelancers, agencies and sales teams to create professional looking client proposals.

He launched this top-rated proposal software on the side nine years ago, working nights and weekends, and grew it into a profitable product shortly after it launched. He’s also now starting a new SaaS called Docsketch, which is an electronic signature product that gets sales documents signed 40% faster.
