Dataminr is an AI platform that analyzes over 1 million public data sources—including text in 150 languages, images, video, and sensor data—to detect breaking events, emerging risks, and threats in real-time. It processes nearly 500,000 daily events and alerts users to critical information across physical, digital, and cyber domains before mainstream media or traditional sources. The platform serves enterprise, government, and media organizations seeking early warning signals of high-impact incidents. Dataminr differentiates through multimodal AI fusion, global scope covering 100+ countries, and speed of detection that has repeatedly beaten traditional news by hours.

Hammerspace is a metadata-driven data orchestration platform that sits above file and object storage systems, providing a unified global namespace for accessing unstructured data across on-premises and public cloud infrastructure. Rather than storing data itself, it acts as a software layer that enables enterprises to access files regardless of storage type, vendor, or location while optimizing performance for AI and HPC workloads. The platform automatically transitions data between high-performance Tier 0 storage during compute-intensive operations and cost-efficient object storage during idle periods, eliminating GPU idle time caused by data bottlenecks.

Horizon3.ai provides NodeZero, an autonomous penetration testing platform that continuously simulates real-world attacks without agents or human intervention. The SaaS solution safely executes attack chains across AWS, Azure, and Kubernetes infrastructure to show exactly how attackers compromise systems and what data they access. Organizations use it to verify security fixes in production and stay ahead of evolving threats at scale.

Supabase is an open-source backend-as-a-service platform that provides developers with a PostgreSQL database, authentication, instant APIs, real-time subscriptions, edge functions, and storage—all accessible through a web interface. It eliminates backend infrastructure setup, allowing developers to focus on frontend development while maintaining full control over their data through self-hosting capabilities. The platform has become the default backend for AI coding tools like Bolt and Lovable, and serves over 4 million developers including 36% of recent Y Combinator batches.

Clay is a data enrichment and automation platform that enables sales and growth teams to find, research, and personalize outreach to leads at scale. It functions as a smart spreadsheet that orchestrates data from 150+ sources, applies AI-powered workflows for enrichment and content generation, and automates prospecting without manual labor. Clay uses signal-led prospecting to identify buyers based on real-world triggers like funding rounds or hiring, making personalized outreach possible without expensive tools or manual work.

Laurel is an AI-native time intelligence platform that passively captures digital work activity and uses firm-specific large language models to automatically generate structured, compliant time entries and billing narratives. Built specifically for enterprise professional services firms, it eliminates manual timekeeping while helping lawyers and accountants recover an average of 28 billable minutes per day—translating to 4-11% profit increases. Laurel is the first and only company applying generative AI to enterprise timekeeping, processing over $4.4 billion in professional time annually.

Snorkel AI is a data development platform that enables enterprises to programmatically label and curate training data for AI systems, including LLMs and RAG pipelines. Rather than expensive manual labeling, it uses labeling functions that encode expert intuition through heuristics, legacy models, and LLM calls to scale data preparation. Used by Fortune 500 companies, top US banks, and government agencies to build production AI applications faster and more cost-effectively. It represents a shift toward data-centric AI, where high-quality labeled data is the bottleneck rather than model architecture.

OnPay is a cloud-based payroll and HR platform that helps small to mid-sized businesses run unlimited payroll runs for a flat monthly fee of $49 plus $6 per employee. Unlike competitors with tiered pricing and add-on features, OnPay bundles all payroll capabilities—tax filings, multi-state support, off-cycle runs, and HR functions—into a single transparent plan. The company serves over 25,000 businesses nationwide and is backed by $128M in funding, positioning itself as the simplest, most affordable payroll solution for cost-conscious businesses.

AIRIA is an enterprise AI platform that unifies orchestration, security, and governance in a single solution, enabling organizations to build, deploy, and govern AI agents and automated workflows at scale. The platform provides a model-agnostic control layer with an Agent Builder supporting no-code, low-code, and pro-code development, plus out-of-the-box connectors for enterprise systems like Salesforce, Microsoft OneDrive, and Slack. AIRIA differentiates by eliminating tool sprawl—delivering all three dimensions (orchestration, security, governance) in one unified platform rather than stitching together disconnected point solutions.

Employee Navigator is a broker-centric benefits administration platform that consolidates benefits enrollment, compliance, onboarding, and payroll integration into a single system. It automates the exchange of benefits data between employers, brokers, insurance carriers, and payroll providers, reducing manual work and compliance risk. The platform connects 195,000+ employers, 7,000+ brokers, and 600+ partners, positioning itself as an agnostic marketplace rather than an enterprise HCM suite.

Majestic Labs builds Prometheus, a custom AI server that solves the memory wall problem by disaggregating memory from compute, enabling up to 128 TB of ultra-fast, power-efficient memory per server—nearly 100x more than leading GPU servers. The system allows organizations to run multi-trillion-parameter LLMs, mixture-of-experts models, and agentic AI systems in a single unit while dramatically reducing power consumption and infrastructure costs. Built by veteran silicon architects from Meta and Google, the company targets hyperscalers and enterprises that need to deploy massive AI models efficiently.

Quantum Art is a full-stack trapped-ion quantum computing company developing scalable quantum hardware with proprietary multi-core ion chain architecture. The company aims to deliver quantum systems with 100x faster gate speeds, 100x more parallel operations, and 50x smaller footprint compared to competitor roadmaps. Founded as a Weizmann Institute spin-off with deep expertise from Nobel laureate collaborators, Quantum Art targets near-term quantum advantage by 2027 and million-qubit systems by 2033.

ZaiNar provides real-time sub-meter positioning and location intelligence using patented phase-based signal processing and sub-nanosecond time synchronization on existing radio infrastructure.
