Stacker

Stacker AI is an AI-powered platform for building portals and business software. Instead of writing code or learning a new tool, you describe what your business needs and Stacker AI builds it . Building with Stacker AI is conversational. You tell it who your portal is for (clients, partners, vendors, your own team) and describe what they need to see and do. Stacker AI asks clarifying questions, makes suggestions, and builds the app with you. You steer, it builds. The whole process takes minutes, not weeks. You don't need technical skills, coding experience, or time to learn a platform.

Assembly

Assembly is the AI-powered platform for professional service firms, from accounting and bookkeeping practices to agencies and consultants. It combines a branded client portal, a simple CRM, and an AI app builder that lets your firm add any software it needs without a dev team. Clients get one branded place for messages, files, forms, tasks, contracts and e-signatures, and invoices they can pay online. Your team runs on a CRM with automated reminders and an AI Assistant that knows full client context. When your firm needs something the portal doesn’t do yet, describe it.
