ApertureDB is a unified database that natively stores and manages images, videos, documents, embeddings, and metadata in a single system with built-in knowledge graph and vector search capabilities. It eliminates the need for enterprises to manually integrate cloud storage, vector databases, and processing libraries by providing a single interface for multimodal AI workloads. The platform is 35x faster at mobilizing multimodal datasets than traditional approaches and 2-4x faster than open-source vector databases, reducing infrastructure setup time by 6-12 months.

H Company builds enterprise AI agents and agentic models capable of autonomously interfacing with software systems to automate complex workflows. The company's Holo3 family of models can understand and interact with any graphical user interface—web applications, desktop software, cloud platforms—to perform multi-step tasks like clicking, typing, and navigation. H's product suite includes Runner H (workflow automation API), Surfer H (web interface automation), and Tester H (automated software testing), claiming 92.2% success rates while reducing operational costs by up to 5.5x compared to OpenAI, Anthropic, and Google. Founded in 2023 by DeepMind veterans and backed by $220M from Eric Schmidt, Amazon, and tier-1 investors, H is positioned as Europe's leading agentic AI startup.

Voltron Data builds Theseus, a GPU-accelerated query engine that enables petabyte-scale data analytics directly on data lakes, lakehouses, and warehouses using Apache Arrow standards. The platform allows organizations to query massive datasets 10-100x faster while reducing infrastructure costs dramatically—one retailer cut server count from 1,400 CPU machines to 14 GPU servers. Unlike traditional CPU-based analytics platforms, Voltron's approach is designed to complement existing systems like Spark and DuckDB, letting users scale without vendor lock-in.
