DayOne develops hyperscale data center infrastructure optimized for cloud, AI, and edge computing workloads. The company offers modular build systems, advanced liquid cooling, and infrastructure management tools designed for rapid deployment and operational resilience. DayOne serves US and Chinese hyperscalers with a focus on sustainability, strategic new markets, and fast time-to-deployment. The company has secured approximately 1GW of customer commitments and operates as a next-generation colocation platform with greenfield developments across Asia-Pacific and Europe.

Nexthop AI builds custom networking infrastructure purpose-built for AI workloads in hyperscale cloud data centers. The company combines custom hardware, software, and optical integration using a JDM (Joint Development Manufacturer) model to deliver tightly integrated solutions for GPU clusters. Nexthop's Disaggregated Spine architecture achieves up to 30% reductions in energy consumption and infrastructure costs while supporting extreme throughput (50-100+ terabits) compared to traditional networking vendors like Cisco and Juniper.

Crosslink Capital is an early-stage venture capital firm founded in 1989 that invests $1-9M in Seed and Series A technology companies across enterprise software, financial services, and IT infrastructure. Beyond capital deployment, the firm provides portfolio companies with access to its proprietary Alpha Network—an invite-only community of 2,000+ founders, CEOs, and operators—plus dedicated support teams in San Francisco and Menlo Park offering talent networks, business development, and strategic guidance. Crosslink manages over $4.2B in assets across venture and public equity strategies, with a track record including exits like Postmates (acquired by Uber), Chime, and Coupa.

Together AI is an AI Acceleration Cloud platform enabling developers and researchers to train, fine-tune, and deploy generative AI models at scale. The platform supports over 200 open-source models across all modalities (chat, image, audio, vision, code, embeddings) with 2-3x faster inference than hyperscalers, OpenAI-compatible endpoints, and infrastructure scaling from 16 to 100,000+ GPUs. Founded by Stanford professors and serial entrepreneurs, Together AI is positioned as the cloud infrastructure layer for the open-source AI ecosystem, with recent expansion into data transformation through the Refuel.ai acquisition.

Meter delivers enterprise networking as a fully integrated service, combining custom-built hardware (firewalls, switches, access points, 5G gateways), proprietary software, and managed operations into a single subscription. The company disrupts traditional networking by eliminating the need for separate hardware vendors and IT operations, delivering secure, reliable connectivity across branch offices, campuses, and data centers. Meter's vertically integrated approach—designing and manufacturing all components simultaneously—enables superior performance, security, and scalability compared to best-of-breed alternatives.

Thought Machine builds Vault Core, a cloud-native core banking platform that enables banks to run any financial product they design using smart contracts and a real-time ledger architecture. Unlike legacy monolithic systems, Vault Core is cloud-agnostic, microservices-based, and allows banks to migrate existing products while innovating new ones without disruption. The company also offers Vault Payments for global payment processing. Backed by tier-1 banks including JPMorgan Chase, ING, and Lloyds Banking Group as both customers and investors, Thought Machine has become the infrastructure layer modernizing legacy banking systems.

Dash0 is an OpenTelemetry-native observability platform that helps engineering teams monitor metrics, logs, traces, and resources with built-in alerting, dashboards, and AI-powered troubleshooting. Unlike legacy observability tools, Dash0 generates vendor-agnostic, standardized data that isn't locked into proprietary formats. The platform solves the observability crisis—too noisy, too expensive, and too complex—with transparent consumption-based pricing and an AI copilot called Agent0 for intelligent incident investigation.

Together AI is an AI Acceleration Cloud platform that enables developers and enterprises to train, fine-tune, and deploy generative AI models with 2-3x faster inference than hyperscalers. Supporting 200+ open-source models across all modalities, it provides the complete AI lifecycle from training to inference without vendor lock-in or infrastructure management burden. The platform powers 450,000+ AI developers and enterprises including Salesforce, Zoom, and SK Telecom with enterprise-grade security, model ownership, and performance.

Decart is an AI research lab building the fastest and most efficient generative AI models for real-time video generation and manipulation. Their flagship products—Oasis (real-time AI game world) and Mirage (live video editing via text prompts)—achieve 10x better efficiency than competitors like OpenAI's Sora, reducing inference costs from $100/hour to $0.25/hour. The company combines a proprietary LLM inference engine (built from scratch in C++ and CUDA) with advanced video generation capabilities, serving developers, enterprises, and streaming/gaming platforms.
