Ambi is building the interface for the AI era - software and hardware that move at the speed of thought. We're creating a living memory system that turns conversations, meetings, and daily signals into one connected knowledge base, across phone, watch, and desktop. Backed and early-stage, headquartered in San Francisco with hybrid flexibility - this is a ground-floor seat on category-defining hardware.

Arbio, headquartered in Berlin, Germany, is building an AI-native property management platform for short-term rentals across Europe. It currently manages over 1,000 apartments and operates real properties in Berlin, Hamburg, Vienna, and Leipzig, with plans to expand to additional European cities. The company has raised a $36 million Series A funding and maintains an engineering team of five engineers. Arbio’s platform uses AI to observe, decide, and act on real-world property operations with humans in the loop, enabling AI-assisted management of short-term rental properties across Europe.

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).
