I tried and failed at making a CRM.

The problem with developing and marketing CRMs is:

1. Very crowded space

2. You need to attract a lot of customers because revenue/customer for SaaS apps like CRMs are low: https://highrisehq.com/signup for example. When most of your customers will be on the free plan or paying you just $30-$40/month you'll need to attract 1000s in a very crowded space with plenty of low cost options around.

3. You can't tightly integrate email without going to a lot of trouble or resorting to a hack b/c Gmail and other services don't allow you to integrate their special sauce into your application. And IMAP isn't a viable option because of the low revenue/customer (IMAP is heavy and will cost you in bandwidth and storage).

4. Mission critical. If your CRM goes down even for a few minutes and you have 1000s of customers you're going to get a lot of angry phone calls. Not to mention a whole host of other issues that can go wrong like data loss, security breaches. Don't forget this is sensitive business data you'll be acting as a gatekeeper for. If something fails it'll be your head.
