Faithful user for years
I've used Salesflare for years now, even through some employers forcing their CRMs on me. Including the largest and most annoying ones (eww).
Salesflare has consistenly been one of the top 3 tools in my toolbox, i just love the simplicity and effectiveness of it. I now use it for my own startup and don't miss a thing. Over the years it has stayed true to its character, not overbuilding unnecessary features and just keeping things smooth on a well tuned machine.
I've occasionally had a chance to try other CRMs just out of curiosity and I can say I never even considered one of them being even close to replacing Salesflare for me.
