What app do you guys use to track contacts?

[Tony Lin]

Hey guys, 

What app/site do you guys use to keep track of potential investors and people who have invested in deals? I'm looking for a few features: 

- Ability to make notes about investors background

- Ability to include contacts into individual deals list

- Ability to create a deal funding funnel to track people going through being interested, coming to webinar, submitting PPM, wiring funds, etc. 

Thanks.
