There’s a silent problem at the heart of the artificial intelligence revolution that no one talks about at conferences or makes headlines: AI tools forget everything. Every time an employee opens their AI assistant, that tool remembers nothing that happened the previous session. You don’t know what decisions the team made last month, you have no record of the client who rejected the proposal in February, you don’t know the company’s strategy or the goals for the quarter. Start, literally, from scratch.
It is on this problem—ignored by large technology platforms despite the fact that global investment in AI exceeded $581 billion in 2025—that the Argentine startup CTX0 built its proposal. This week it announced the production launch of NEST, which is billed as the first organizational memory hub for artificial intelligence: a free, self-hosted platform that acts as connective tissue between all the AI tools an organization uses.
The idea behind NEST is as simple as it is powerful. Instead of each AI application functioning as an island, the platform creates a shared, persistent memory that learns from each employee, accumulates context over time, and makes it available to the entire organization. When someone leaves, their knowledge does not disappear. When someone comes in, they already have context from day one.
“We saw organizations spend millions on AI and none could answer a basic question: is it working? The problem was not the technology. No one had built the infrastructure,” explained Carolina Fogliato, co-founder and CEO of CTX0, with experience at KPMG and more than a decade building data-driven companies.
In concrete terms, NEST integrates with more than 700 artificial intelligence models through a scheme in which each organization uses its own access keys – without intermediaries or extra costs -, runs on the client’s own infrastructure to guarantee total sovereignty over the data, and replaces more than fifteen fragmented tools on a single unified platform. One of its most striking side effects is the reduction in the consumption of tokens – the unit of cost in language models – between 40 and 60 percent, thanks to the shared context that avoids having to re-explain the same knowledge in each session.
The practical impact varies by role. The sales manager accesses an assistant who already knows the story of each client without anyone telling it to him or her. The product manager finds each roadmap decision or user feedback in seconds, without tracking in Slack, Notion or emails. The CEO can prepare an important meeting in minutes because the system already knows the strategy, active risks, and tone of each key relationship.
CTX0 also introduces YIELD, its own metric that quantifies for the first time the real economic return of artificial intelligence in an organization, measuring the cost per approved output. According to the company’s data, with its platform this cost drops from 1.80 to 0.42 dollars, while the approval rate of the results generated by AI rises from 54 to 87 percent.
NEST’s memory engine—named HIVE—is built on Neo4j, a graph database that allows context to be retained and related at an organizational scale, a technical architecture that the founders consider the real differential compared to more superficial solutions.
The business model follows a logic of progressive adoption: NEST is free forever in its self-hosted version. Paid plans—starting at $49 per user per month—enable advanced features such as agent crews, ROI analytics, and multi-agent orchestration. The sovereign architecture also positions CTX0 as a natural choice for European companies that will need to comply with the EU AI Act, which comes into full effect in August 2026. The platform is available today at ctx0.io, with no registration required.
