The Postgres Company That Let AI Write the Signups
It started as the open-source answer to Firebase. Then AI coding agents adopted it as their default backend, and Supabase doubled its valuation to $10.5 billion in eight months.
The Search Engine That Learned Three Jobs
Elastic began with a recipe search problem. Today, the same engine retrieves context for AI agents, traces a failing service and helps a security analyst find the one alert that matters.
Shaped
Shaped is a New York-based AI company that builds a real-time relevance engine for recommendations, search, and agent retrieval. Its managed platform, Shaped Cloud, combines embeddings, machine-learning models, and fresh behavioral data to return personalized results in under 50 milliseconds, letting product and engineering teams add for-you feeds, hybrid search, and personalized discovery without building ranking infrastructure from scratch. Founded in 2021 by Tullie Murrell, Daniel Camilleri, and Shai Bruhis, the company raised an $8M Series A led by Madrona in 2024 and was acquired by live-commerce marketplace Whatnot in July 2026.
Upstash
Upstash is a serverless data platform built for developers who deploy at the edge. Its flagship product is a Redis-compatible database that talks over HTTP instead of a persistent TCP connection, which makes it work inside serverless and edge runtimes where traditional Redis breaks. Around that core it has added QStash (a serverless message queue and scheduler), Upstash Vector (a serverless vector database), Search, and Workflow (durable serverless functions). Everything is priced per request with a guaranteed cap, so developers start free and pay only for what they use. Founded in 2020 by ex-Hazelcast engineers, Upstash powers Vercel KV under the hood and reached $1M ARR two years after its seed round.
Auguria, Inc.
Auguria is a cybersecurity AI company that builds the Security Knowledge Layer (SKL), a vector-based platform that ingests the flood of logs, events, and telemetry that security teams collect, then denoises, classifies, and prioritizes it - filtering out roughly 99% of the noise so analysts can focus on the ~1% of events that actually matter. Founded in 2022 by Keith Palumbo and Chris Coulter and emerged from stealth in March 2024 with $6.5M in seed funding from SYN Ventures and SentinelOne's S Ventures, Auguria plugs into existing SIEM and data-lake infrastructure to cut security data costs and surface threats others miss.
Orama
Orama is an open-source search company building an 'answer engine' for developers - a lightweight, high-performance stack that bundles full-text, vector, and hybrid search with automatic embedding generation and built-in LLMs. Started as the open-source project Lyra and incorporated as OramaSearch Inc. in 2023 by Issac Roth and Michele Riva, its core library ships in under 2KB and runs in the browser, on servers, or at the edge. Orama powers site search and AI answers for developer platforms including nodejs.org, tanstack.com, and solidjs.org, and its OramaCore runtime packages a search engine, vector database, and LLM interface into one deployable unit.
Superlinked, Inc.
Superlinked is a San Francisco-based infrastructure company building the 'vector computer' - a compute and data engineering framework that turns complex enterprise data into vector embeddings for Search, RAG, Recommendations and Analytics. It now also ships an open-source Inference Engine that lets agent teams self-host every model their agents call, claiming roughly 50x cost savings vs hosted per-token APIs.
Redis
Redis is the company behind the world's most popular in-memory data store, the open-source database that began as a side project by Salvatore Sanfilippo in 2009 and now sits in the stack of most of the internet's largest applications. It sells managed and self-hosted enterprise versions - Redis Cloud and Redis Software - layered on the open-source core, and has pushed hard into real-time AI use cases like vector search and LLM memory. After a turbulent 2024 licensing fight that spawned the AWS-backed Valkey fork, Redis returned to an open-source license (AGPLv3) with Redis 8 in 2025.
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.
