Simular Raises $21.5M for Desktop AI Agent with Novel Neuro-Symbolic Approach

Simular, an AI agent startup founded by ex-Google DeepMind researchers, has raised $21.5M Series A to develop autonomous agents that control Mac OS and Windows PCs directly rather than just browsers. The company uses a "neuro-symbolic" approach where agents explore tasks freely until successful, then convert the workflow into deterministic code to prevent hallucinations in repeated executions. Simular has released version 1.0 for Mac and is part of Microsoft's Windows 365 for Agents program.

Mistral Releases Mistral 3 Family: Open-Weight Frontier Model and Nine Efficient Small Models
