What is your sales process going to look like? Figure out your requirements and it will make your search easier. I really like Close.io for cold outbound sales. If you're doing social media then maybe look at Nimble. As someone else said you can get started for free with Hubspot. Intercom might be something to look at as well if your going for a more automated process. You can obviously use Zapier to tie your software together so you can use best in class software for whatever processes you end up putting in place.
