Hey Ariel Diaz.
Great list. Happy to see some of my favourite tools on the list. I was surprised to find Trello instead of Basecamp on the early tools list. I have used both tools and decided to stick with Basecamp. Was it because of the free vs paid tool? Or is it the Kanban view?
Also would recommend to see Freshsales — Sales CRM as an option for CRM for Startups. It has Email, Phone, Activity Tracking in-built and is also available on a free plan.
Once again, thanks for the list. Checking out Blissfully — Looks interesting.
