Launch YC: Praxos - Kernel for AI Agents

"Turn data into agent memory"

TL;DR: Building reliable AI agents is a nightmare of wrangling with context, prompt engineering, bespoke scaffolding, and unpredictable failures. Praxos is a Kernel for AI, providing everything you need to build stateful agents with confidence.

Founded by Lucas Urbisaia & Soheil Sadabadi

The Problem

Building stateful AI agents that can reliably handle complex tasks is incredibly difficult. Current approaches require developers to build massive, custom scaffolding for each use case—manually managing state and cramming huge amounts of context into the prompt to simulate memory, while processing all their data on their own.

This leads to brittle systems prone to inconsistent state, memory gaps, and unpredictable behavior. Dev teams spend most of their time building low-level plumbing, trying to guide behavior and get the right data, instead of focusing on core capabilities. This makes it difficult to build and maintain sophisticated agents and nearly impossible to connect them all together.

The Solution

Praxos provides a kernel for AI agents: an environment that lets you combine speed and accuracy with reliability and scalability. It enables you to move from crafting fragile one-offs to engineering robust, auditable, and scalable AI systems.

Here’s how it works:

  1. Their engine first transforms your source data (docs, APIs, DBs) into a Typed Knowledge Graph. This acts as a reliable 'source of truth' and structured memory, making complex data relationships explicit and accessible to the AI.
  2. Their Kernel is built around this graph. They will be adding every service needed for stability (e.g Semantic Validation, Orchestration, Lifecycle management) piece by piece, allowing agents to execute complex, multi-step workflows reliably and consistently.

The result is that you can build sophisticated agents faster, with far greater stability and control.

Where They Are Today: Memory

They are building the full Praxos Kernel brick by brick, and they started with the most critical challenge: solving the data problem for AI, once and for all. Today, this foundational layer of Praxos is live and available through our SDK.

They can parse any data source, from unstructured PDFs and API streams to conversational messages to structured databases—and automatically transform them into a single Knowledge Graph, ready for both search and structured extraction.

Everything in this graph is semantically typed and its relationships are made explicit, turning your chaotic data into a clean, queryable universe of understanding that an AI can reliably use. Whether you need to query for the answer to a question or to extract data in a way that makes sense for the current use case, Praxos does it all, with no requerying needed.

What you can build with the Praxos SDK right now:

  • Next-Generation Retrieval: Build retrieval systems that understand the relationships between documents, entities, and concepts. Deliver far more accurate and context-aware results than what's possible with simple semantic search alone.
  • Unify Your Data Silos: Ingest data from completely different sources and see it live side-by-side in a coherent, queryable graph. Ask questions that span across your PDFs, your user database, and real-time APIs.
  • Power Intelligent Q&A Systems: Create applications that can answer complex questions by traversing the relationships in your data, providing nuanced answers and insights instead of just returning document chunks.
  • Lay the Groundwork for Advanced Agents: Start building your application's long-term memory and 'brain' on their stable, structured foundation today. When the full Praxos Kernel services launch, your application's core knowledge will be ready to be orchestrated.
  • Get structured data for any AI workflow, without needing to requery with AI.

They believe that building robust AI starts with a robust data foundation. That foundation is here, and it's ready for you to build on.
