Sigma positions itself as the bridge between spreadsheet simplicity and modern cloud data architecture, combining spreadsheet familiarity with enterprise-grade BI capabilities.

Blackpoint Cyber delivers 24/7 managed detection, response, and remediation (MDR) services powered by a human-led Security Operations Center. The platform detects advanced threats by identifying malicious use of legitimate IT administration tools—a blind spot for traditional EDR and antivirus solutions. Built specifically for MSPs and their customers, Blackpoint eliminates alert fatigue by taking remediation action in real-time rather than leaving it to customers.

Blockstream provides interoperable blockchain infrastructure and Bitcoin layer-2 solutions, including the Liquid Network sidechain, Core Lightning implementation, and Blockstream Satellite for global Bitcoin access. The company serves financial institutions, cryptocurrency exchanges, and developers building Bitcoin-native applications. Their integrated approach uniquely combines asset issuance, confidential transactions, and Lightning Network payments in a single platform, differentiating them from competitors focused on single-layer solutions.

Kai is an AI-native cybersecurity platform that autonomously performs critical security tasks across IT and OT environments without human intervention. Built from the ground up by the founders of category-defining companies Claroty and SecurityMatters, it integrates threat detection, vulnerability management, compliance automation, and remediation into a unified agentic AI system. Unlike legacy security tools that bolt AI onto fragmented dashboards, Kai reasons and acts at machine speed to eliminate human-speed bottlenecks in security operations.

Oasis Security is a platform for discovering, inventorying, and securing non-human identities (service accounts, API keys, secrets, tokens, certificates) across hybrid cloud environments. The platform combines automated discovery with contextual risk assessment and policy-driven remediation to enforce least privilege access without manual overhead. Founded by former Israeli intelligence operatives, Oasis has raised $195M and serves Fortune 500 enterprises including Chipotle, JLL, and Mercury Financial, achieving 5x ARR growth year-over-year.

XBOW is an AI-powered autonomous penetration testing platform that identifies and exploits vulnerabilities in web applications without human intervention. Using swarms of AI agents, it simultaneously explores multiple attack vectors, reducing testing times from weeks to hours while providing reproducible proof of exploitation.

Labelbox is a data-centric AI platform that helps AI teams and Fortune 500 enterprises create, manage, and iterate on high-quality labeled training data at scale. The platform combines a collaborative annotation software with managed labeling services and generative AI automation (Foundry) to reduce the time and cost of producing training data. It processes petabytes of multimodal data and serves over 80% of Fortune 500 AI teams, positioning itself as a command center for the entire ML training data iteration loop.

TimescaleDB is an open-source PostgreSQL extension optimized for time-series data, delivering 10-100x faster query performance than MongoDB and InfluxDB while supporting millions of events per second with up to 95% storage compression. Built by Ajay Kulkarni and Michael Freedman (Princeton professor), it serves companies ingesting and analyzing massive volumes of time-stamped data across IoT, blockchain, maritime, and industrial applications. The product maintains full PostgreSQL compatibility—same drivers, clients, and SQL—while adding automatic time-partitioning (hypertables) and columnar compression.

Pasqal develops quantum processing units (QPUs) based on neutral atom technology, where individual atoms trapped by optical tweezers serve as qubits. The company integrates quantum computing into HPC and cloud environments to solve optimization, simulation, and AI workloads for enterprises.
