dotData
dotData is a Silicon Valley enterprise AI company that automates the most time-consuming part of data science: feature engineering. Spun out of NEC Corporation in 2018 and led by founder Ryohei Fujimaki, dotData builds software that automatically discovers signals hidden across multiple data tables and turns them into predictive features and business hypotheses. Its products - dotData Enterprise, Feature Factory, and the generative-AI-powered dotData Insight - let analysts and data scientists build models and surface KPI drivers in a fraction of the usual time, and are used heavily in financial services, insurance, manufacturing, retail, and telecom.
Nixtla
Nixtla is a San Francisco time-series intelligence company best known for TimeGPT, one of the first production-ready foundation models built specifically for forecasting and anomaly detection. It started as the open-source Nixtlaverse - libraries like StatsForecast and NeuralForecast with tens of millions of downloads - and now sells an enterprise platform that lets organizations forecast demand, detect anomalies, and support decisions with a few lines of code, on-premises or in the cloud.
Imply
Imply is a San Francisco-based data analytics company that built its platform on Apache Druid - the open-source real-time analytics database that its co-founders helped create. The company offers Imply Polaris, a fully managed cloud database-as-a-service for real-time analytics, and Imply Lumi, billed as the industry's first Observability Warehouse. With $215M in total funding and unicorn status at a $1.1B valuation, Imply serves 100+ enterprise customers including Atlassian, Reddit, and Cisco ThousandEyes, enabling sub-second query performance across terabytes to petabytes of streaming and historical data.
Tiger Data (creators of TimescaleDB)
Tiger Data - formerly Timescale - is the New York-based company behind TimescaleDB, an open-source PostgreSQL extension that began as a time-series workhorse and has grown into a full operational database platform for transactional, analytical, and agentic workloads. In June 2025 the company rebranded around its long-time tiger mascot and now ships Tiger Cloud, Tiger Postgres, and Agentic Postgres - a Postgres flavor purpose-built for AI agents with zero-copy forks, hybrid storage, BM25 and vector search, and an MCP server.
