Saleslogix is one of the oldest enterprise CRM vendors, managing to acquire 10,000 clients over its fifteen year history. Things haven't been easy for Saleslogix, as it changed hands twice in the recent years (first sold to Swiftpage and later to Infor), partly due to high pricing and partly due to the fact that Saleslogix has been very slow to embrace cloud (cloud option is available, but good luck trying to find how much it costs and which features are available in cloud). If you are looking for a free Saleslogix alternative available both in cloud and on-premise, Bitrix24 makes a good choice.
