Amperity
Amperity is a Seattle-based enterprise software company that builds an AI-powered customer data platform. Its patented machine-learning identity resolution engine, Stitch, unifies fragmented customer records from disparate sources - email, phone, address, loyalty and device IDs - into a single, accurate view of each customer. Founded in 2016 by Kabir Shahani and Derek Slager, Amperity helps global consumer brands like Alaska Airlines, DICK'S Sporting Goods, and Wyndham turn messy data into reliable profiles, predictive insights, and activation across marketing, analytics, and AI. The company reached unicorn status in 2021 with a $100M Series D and has since pivoted toward an AI-first, lakehouse-native architecture that runs directly inside Databricks and Snowflake.
DeltaStream
DeltaStream is a Menlo Park-based company building a unified, serverless stream processing platform on top of Apache Flink. Founded in 2021 by Hojjat Jafarpour, the creator of ksqlDB, it lets teams build real-time streaming applications and pipelines using SQL - without wrestling with Flink's operational complexity. Its Fusion platform combines streaming, real-time, and batch analytics into a single serverless experience, integrating with Kafka, Kinesis, Snowflake, Databricks, and Apache Iceberg. The company has raised $25M total, backed by NEA, Galaxy Interactive, and Sanabil.
Spiral
Spiral is a New York-based data infrastructure company building a database reimagined from the ground up for the AI era - what it calls the 'Third Age of Data,' when machines, not humans, are the primary consumers of data. Built on Vortex, an open-source columnar file format donated to the Linux Foundation, Spiral streams data directly from object storage into GPU memory, unifies governance across every data type from tiny embeddings to massive video, and aims to keep expensive GPUs saturated instead of idle. Founded by ex-Palantir and ex-Citadel engineers, it emerged from stealth in September 2025 with $22M in Seed and Series A funding led by General Catalyst and Amplify Partners.
LanceDB
LanceDB builds the data backbone for multimodal AI. Its open-source Lance columnar format and lakehouse let teams store, search, and train on text, images, video and embeddings in one system - replacing the brittle stack of Parquet files, vector stores and feature pipelines that AI teams usually stitch together. Used by Midjourney, Runway, Character.AI, WeRide and others, LanceDB raised a $30M Series A in 2025, bringing total funding to roughly $41M.
Prophecy
Prophecy is an AI-powered data engineering platform that turns visual workflows into production-grade Spark and SQL code, letting analysts and engineers build, deploy, and govern pipelines together on Databricks, Snowflake, and BigQuery.
