Wow, you can tell it's Monday! Haters gonna hate. Not sure
if it belongs in ShowHN, but as someone familiar with the company I can say that Upcall outsources outbound calling for inbound leads. For the uninitiated, that means people who've requested to be contacted by phone and given their phone number for that very reason. As a former tech sales exec, I'm always amused by engineers who think their salary comes out of thin air, or that your VCs don't expect a profit at some point. Someone has to sell what you're coding, and that generally involves a phone call, and there is a correlation between deals closing and the speed with which someone responds to a warm lead. Upcall's goal is to fill that need.
In 2013 a very highly-placed Goldman Sachs exec, a friend of a friend, told me his AMFAR contacts predicted a 'genetics-based cure' in a 3-4 years instead of the 10 years they publicly projected. The rationale was donations would stop if people knew how close they were to a cure.
