## Products (Product Studio)

- [Praxiom AI](https://www.praxiomai.xyz): Product discovery from real evidence. Praxiom turns customer interviews, support tickets, surveys and call recordings into scored insights, prioritised opportunities and PRDs that link back to the quotes behind them. Status: Live.
- [agentFast](https://www.getagentfast.com): The production framework for AI agents. agentFast sits above whichever agent framework you already use and adds what production needs: durable execution, human approval before risky actions, memory, guardrails, evals, tracing and live streaming. Status: Live.
- [Propel](https://www.einsteinlabz.com/studio#propel): You ship. Propel sells. Propel is a growth agent for technical founders. It reads your website and repository, works out who the product is for and what is worth saying, then runs marketing and sales as one loop. Status: In development.

## Research (NeoLab)

- [Propel Gym](https://www.einsteinlabz.com/neolab/propel-gym): Simulated markets where go-to-market agents are graded on what they learn and decide, against a truth the agent cannot see. Track: Verifiable intelligence. Status: In progress.
- [PMEval](https://www.einsteinlabz.com/neolab/pmeval): A benchmark for AI agents doing the actual work of a product manager. Track: Verifiable intelligence. Status: Prototype.
- [agent-stream](https://www.einsteinlabz.com/neolab/agent-stream): An open event protocol for streaming what an agent is doing (tokens, tool calls, thinking, progress) to any interface. Track: Reliable and coordinated agents. Status: Prototype.
- [Papyrus](https://www.einsteinlabz.com/neolab/papyrus): Turns documents into Markdown that agents can read and cite, with structure and page anchors preserved and no LLM in the conversion path. Track: Context and memory. Status: Prototype.

- [Grading go-to-market agents honestly](https://www.einsteinlabz.com/blog/grading-go-to-market-agents-honestly): Why real outcomes are a poor teacher for marketing and sales agents, and how Propel Gym grades them against a hidden truth instead. Design notes; no results yet.
- [What it takes for an agent run to survive a crash](https://www.einsteinlabz.com/blog/what-it-takes-for-an-agent-run-to-survive-a-crash): An agent waiting for human approval should survive its server dying. How agentFast tests that with a real SIGKILL, and how the agent-stream protocol keeps runs legible.
