I have always admired the transparency of companies like Buffer and Moz. They openly share data on the development of their business, including their revenue data and salary data. I also greatly appreciate the open approach of Tomasz Tunguz in sharing data about what works for SaaS businesses and the guys at Startups for the rest of us for practical, honest advice. We have learnt a lot from these sites, and we wanted to reciprocate by sharing lessons from our own experience.
