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.

A software engineer turned climate entrepreneur, Bloom previously co-founded Eager - a cloud app marketplace acquired by Cloudflare in 2016 - and served as Director of Product at Cloudflare overseeing Workers, Storage, and Tunnel. In 2020, he pivoted from internet infrastructure to atmospheric infrastructure, co-founding Heirloom alongside Shashank Samala and Noah McQueen. The company has since raised over $354M in total funding, opened its first facility, and secured contracts with Microsoft, Stripe, Shopify, Meta, and JPMorgan.
