HubSpot is a good product for the business it was designed for: a marketing and sales team that will use the hubs it pays for, on a budget that expects per-seat pricing. The people who search for a HubSpot alternative are usually not that business. They have one pipeline, a few forms, an automation or two, and a bill that has grown with every seat and every hub they were told they needed.
Most alternatives on offer are the same shape with a different logo. Salesforce costs more. Pipedrive, Zoho and Close cost less and fix the interface, but they still charge by the seat and still assume your process fits a standard pipeline. For a lot of small teams, especially ones that quote or whose accounts software has to agree with the CRM, the better answer is a system built around that workflow, running on infrastructure they own.
That is what this page is about. It is written by a team that has set up HubSpot for clients, still builds landing pages in it, and replaced it in our own business with a CRM we built. We know what it does well, and we know what you are paying for that you do not use.
