Avallon AI

Arga Labs provides isolated sandbox environments equipped with API twins of third-party services, enabling developers and organizations to safely test and train AI agents without risking their production systems. By offering a controlled testing ground that mirrors real-world APIs, the company allows teams to experiment with AI implementations, validate workflows, and refine agent behavior in a risk-free setting. This approach addresses a critical need in AI development, where testing in live environments can introduce costly errors or security vulnerabilities.

The company aims to make building affordable by leveraging AI to analyze blueprints. It focuses on building computer vision object detection models and coordinating these models, with an emphasis on ML and algorithm development. The company states it prioritizes the intelligence side (ML and algorithms) over the application side. Backed by investors who have funded PlanGrid, Dropbox, and Airbnb, it has strong backing. It is part of Y Combinator's Winter 2025 batch (YCW25).

The company builds AI conversations that feel like a real person, with real-time, native integration in FaceTime. Its mission is to create a great friend for everyone on Earth by digitizing connection, and it aims to enable AI-driven, real-time conversations within native apps such as iMessage and FaceTime. Backed by BoxGroup, the company is led by a founder who is a Thiel Fellow, YC alum, and Stanford dropout who recently sold his last company. It operates as an engineering-first organization, fully in-person in San Francisco, where it is headquartered.
