Restacked.ai makes it easy to replace bloated SaaS applications like HubSpot, Airtable, and FlightSchedulePro with an AI‑native stack. It is a generative business system for SMBs that runs directly on company data. Instead of relying on pre‑packaged SaaS and adapting internal workflows to whatever those tools allow, teams use chat, agents, and small custom applications built only around the workflows they actually need. Data is exposed through natural language, new tools can be created from prompts, and business logic lives in one place instead of being scattered across CRMs, helpdesks, automation tools, and spreadsheets.

We plant and grow our own tech companies. At our Studio we have pulled together a team of remarkable people. Together we come up with ideas, build digital products and bring them to market. Our startups range from Smart.pr, a mature company in full bloom, to an early stage startup called Journa, still in private beta. The more adventures we start, the more we discover how little we know.
