Reflection AI is building frontier AI models and reasoning systems designed to act as an intelligent middle layer between developers and fully autonomous systems. The company positions itself as both an open-source alternative to closed frontier labs like OpenAI and Anthropic, and a Western equivalent to Chinese AI firms like DeepSeek. Their self-hosted AI agents can reason about code, synthesize features, refactor, debug, and maintain systems while dynamically referencing files and discussions with line-level citations. Enterprise customers deploy Reflection's systems within their own cloud environments (AWS, Azure, GCP) with full privacy and IAM compliance.

Airtable is a spreadsheet-database hybrid that combines the familiar interface of spreadsheets with relational database functionality, enabling non-technical users to build custom applications without coding. Used by over 80% of Fortune 100 companies, it powers workflows across film production, supply chain management, vaccine distribution, and more. The platform offers collaborative data management with flexible field types, attachments, and automation capabilities across free and paid tiers.

ClickHouse is an open-source columnar database management system optimized for real-time online analytical processing (OLAP), enabling complex SQL queries at massive scale with sub-second latency. It achieves hundreds of millions of rows per second throughput—100x faster than competing systems—through its vectorized Merge Tree storage engine and native support for distributed, replicated architectures. The platform serves enterprises handling massive analytical workloads, from event ingestion to interactive dashboards, and is used by companies like Microsoft, Walmart, Tesla, and eBay to process billions of events per minute.

Cockroach Labs builds CockroachDB, a distributed SQL database that combines the ACID transaction guarantees and relational model of traditional databases with the horizontal scalability and fault tolerance of NoSQL systems. It's PostgreSQL wire-compatible and designed to survive datacenter failures with zero manual intervention. The platform serves enterprises and innovators requiring always-on, globally distributed databases that scale seamlessly across cloud providers and on-premises infrastructure.

Yugabyte is an open-source distributed SQL database that combines strong consistency with ACID transactional support across data centers and regions. It supports two APIs—PostgreSQL-compatible YSQL and Cassandra-compatible YCQL—on the same underlying distributed engine, enabling automatic sharding, replication, and dynamic scaling. The company serves cloud-native enterprises in financial services, payments, streaming, and IoT that need multi-region active-active deployments with predictable performance.

Atlas Data Storage commercializes synthetic DNA-based data storage systems that encode digital information into DNA strands using semiconductor-based synthesis and enzyme engineering. Their flagship product, Atlas Eon 100, stores 60 petabytes in 60 cubic inches with 1,000x the density of traditional LTO-10 tape and offers 1,000+ year durability. The company targets enterprise, hyperscale, and government customers seeking permanent, scalable, energy-efficient archival storage solutions.

CData Software provides data integration and connectivity solutions that enable organizations to seamlessly access and move data across cloud, on-premises, and hybrid environments. The company offers three main business models: CData Sync for data replication, embedded connectors for ISVs, and Connect AI for giving AI systems direct access to enterprise data. Over 7,000 organizations including FedEx, Office Depot, and Salesforce rely on CData to solve complex data connectivity challenges across 350+ systems.

VAST Data provides an operating system for AI that unifies compute, storage, and data management into a single platform designed for high-performance AI and analytics workloads. Built on DASE (Disaggregated Shared Everything) architecture, it eliminates data movement bottlenecks through components like VAST DataStore, DataBase, DataEngine, and InsightEngine with NVIDIA. The platform serves enterprises and GPU cloud providers running intensive AI training and inference, with over 25% of Fortune 100 companies adopting it for strategic AI initiatives.

DataStax provides Astra DB, a cloud database-as-a-service built on Apache Cassandra, along with DataStax Enterprise for on-premises deployments and Astra Streaming for event streaming. It solves the operational complexity of managing distributed databases at scale by automating deployment, scaling, backup, and recovery across multiple cloud regions. The platform enables enterprises to build real-time AI applications with low-latency data access and multi-model support (tabular, search, graph) through a serverless, pay-as-you-go architecture.

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.

Veza is the authorization platform for data security built on a graph-based architecture that maps access permissions across 300+ integrations in hybrid and multi-cloud environments. It enables enterprises to visualize, manage, and control granular access down to specific data objects, tables, and cloud resources. Used by Global 500 companies like Expedia, Blackstone, and Wynn Resorts to solve privileged access monitoring, non-human identity security, and identity governance challenges. Recently acquired by ServiceNow in December 2025 at a $1B-$1.5B valuation.

Aiven is a fully managed, open source data platform that handles the operational complexity of streaming, storing, and serving data across AWS, Azure, GCP, and other cloud providers. The platform eliminates the need for companies to hire expensive DevOps specialists by managing infrastructure, scaling, upgrades, and migrations automatically. Built on open source services like Apache Kafka, PostgreSQL, and OpenSearch, Aiven prevents vendor lock-in while delivering enterprise-grade reliability. It serves businesses from startups to Fortune 500 companies across 60+ countries seeking simplified multi-cloud data infrastructure.

DataSnipper is an intelligent automation platform that embeds directly into Excel, allowing auditors to extract data from unstructured sources (invoices, bank statements, documents) with automatic reconciliation and complete audit trails. Used by 600K+ professionals across all Big Four accounting firms and 175+ countries, it solves the manual, error-prone work of matching and verifying financial data. The platform's key differentiator is working within Excel workflows rather than forcing migration to new systems, enabling rapid adoption and high user loyalty.

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.
