About Stacks

Stacks at stackscrm.com is a CRM and business workspace for people running small businesses. It brings contacts, follow-ups, email, invoicing, scheduling, reviews, support and tasks into one place.

Built from an operator's problem

Stacks was built by Chad, a business owner who knows the cost and friction of paying for separate tools that do not work well together. He wanted the everyday customer work in one workspace, without a new charge each time a business adds a teammate.

Chad shares his founder perspective at @chadaltman. Product updates are at @stacks_crm.

Who it is for

Stacks is designed for solo operators, freelancers and small teams that need to keep track of customers and the work around them. Start with a contact and a follow-up, then use the connected tools that fit your business. Browse the feature guides to see the workflows.

How to use Stacks

The core platform is Free with unlimited users and contacts. Free includes 50 one-time AI credits for supported features. If you want continued use of those AI features after the credits are used, AI Pro is optional. For specialized workflows or integrations, Stacks Custom begins with an enquiry and a defined scope; it is not an automatic part of Free or AI Pro. See current plan details.

For setup and product questions, use the help guide. Builders can use the developer guide for the documented API and MCP access. If you want the fuller explanation of why the core is Free, read Why is Stacks free?.
