Clear Street is a cloud-native capital markets platform that replaces legacy 1970s-80s mainframe infrastructure with modern real-time ledger technology. It unifies trading, risk management, financing, clearing, and custody for institutional clients on a single platform. The company serves sophisticated institutional investors—hedge funds, market makers, and ETF issuers—who are too complex for retail platforms but underserved by major bulge-bracket prime brokers. Clear Street generates revenue primarily through net financing (margin, securities lending, and collateralized financing) rather than commissions.

Upwind Security is a cloud security platform that consolidates CSPM, CWPP, CDR, vulnerability management, identity security, and container security into a single offering. It uses eBPF kernel-level monitoring paired with cloud telemetry to detect malicious activity and correlate runtime context with build-time data, reducing alert noise by ~95%. The platform serves enterprise security teams protecting cloud infrastructure across AWS, Azure, and other environments.

PaleBlueDot AI operates a dual-model platform connecting AI startups and enterprises with GPU compute capacity through a real-time marketplace and custom cluster design services. The company aggregates spare GPU capacity from third-party providers and designs large-scale clusters deployed in data centers like Digital Reality Trust and Equinix. With over 80 global clusters, it serves customers across Japan, South Korea, Singapore, and Southeast Asia—including RedNote (Xiaohongshu)—positioning itself as a cost-efficient alternative to hyperscalers for AI workloads.
