About
Sierra Space is a commercial space infrastructure company headquartered in Louisville, Colorado, founded in 2021 as a spinoff of Sierra Nevada Corporation's space business unit. The company operates at the intersection of spacecraft systems, commercial space stations, and in-space manufacturing, targeting the emerging low-Earth orbit (LEO) economy. Its flagship asset is the Dream Chaser spaceplane — a reusable, multi-mission orbital vehicle designed to transport cargo (and eventually crew) to the International Space Station and future commercial destinations. Dream Chaser is the only winged commercial spacecraft under NASA contract, holding a Commercial Resupply Services 2 (CRS-2) agreement that includes at least six cargo missions to the ISS.
Salesforce-owned PaaS hosting 65M+ apps with git-push deployment; Heroku Connect syncs with Salesforce competing with Render and Railway for cloud application platform.
About
Heroku is a cloud application platform (PaaS) that enables developers to deploy, manage, and scale web applications without managing server infrastructure — supporting multiple programming languages (Ruby, Node.js, Python, Java, PHP, Go) and providing a simple git-based deployment workflow that made it the foundational platform for a generation of web developers. Founded in 2007 in San Francisco, Heroku was acquired by Salesforce in 2010 for $212 million and has since powered 65 million+ applications, serving 65 billion+ daily requests, with 200+ ecosystem add-on services in the Heroku Elements Marketplace.\n\nHeroku's deployment model allows developers to push code via git and have it automatically built and deployed to dynos (Heroku's containerized compute units) without configuring servers, load balancers, or deployment pipelines. Managed add-on services (PostgreSQL, Redis, logging, monitoring, email delivery) snap into applications without infrastructure configuration. Heroku Connect enables two-way data synchronization between Heroku PostgreSQL databases and Salesforce objects, creating a natural integration path for Salesforce customers building custom applications on Heroku.\n\nIn 2025, Heroku was named a Leader in the 2025 Gartner Magic Quadrant for Cloud-Native Application Platforms, with a new platform pilot available with GA targeted for early 2025. Heroku competes with Render, Railway, Fly.io, and AWS Elastic Beanstalk for PaaS and managed application hosting. After a period of stagnation under Salesforce ownership (including ending free dynos in 2022 and a high-profile security incident), Heroku has reinvested in the platform with modern infrastructure improvements. The 2025 strategy focuses on winning back developer trust through platform reliability improvements, deepening Salesforce ecosystem integration, and growing enterprise usage through the Salesforce sales channel.
