Sure! Here are a few tools that I found during my research. For the most part, the biggest downfall for all of the tools were how they reported out on information that was coming in. The tools were geared more to being just tools to assist in capturing and storing the leads, but not much beyond that.
Hubspot - the key Inbound Marketing player. They do just about everything a company needs, but in a much more confusing way. The biggest pro is flexibility in areas that matter (like landing pages or blog layouts), but you need to really understand the framework to make a positive difference. They really heavily on support and partnered agency support.
Spokal - Upcoming Hubspot competitor. They are focusing more on the creation element of inbound. The biggest selling point for them is an editorial calendar and a library of content to push to social and blog platforms. Heavy reliance on Wordpress is a downfall.
Leadboxer - This is one of the closest tools to insights on leads that I have found. They rely on proprietary algorithms to generate lead scores and insights on leads and push them through a sales cycle through direct CRM integration. They have fairly small plans, in terms of lead monitoring size.
Full Circle Insights - Marketing insights and lead monitoring are the key features here. It's primarily built around Salesforce, but is used to help marketers match insights with sales report.
Those are a few tools. Marketing SaaS solutions, as a whole, is pretty busy. There are more single feature solutions over AiO solutions and I see the AiO being the bigger push, especially for small to midsize.
