Companies
Parakey was founded in early 2006 by Blake Ross and Joe Hewitt of Mozilla/Firefox fame. Little has been revealed about what Parakey will actually do, but it has been touted as both a platform and set of applications that will merge the desktop environment with the Web. It has also been described as a Web-based operating system. Great emphasis has been placed on Parakey's potential to make tasks on the computer more intuitive for the average Joe. Parakey was acquired by Facebook on July 19, 2007. Sequoia Capital seeded Parakey's operations in early 2005.
Parallel Bio created a human 'immune system in a dish' to discover drugs and immunotherapies more likely to work in patients. Our platform has all of the same elements as a human immune system, meaning you can test drugs and vaccines as if you were testing them in actual patients from the start. The biggest reason why 95% of new drugs fail is that they were tested in mice - but with our human platform, pharma companies will know which drugs will successfully treat patients, speeding up the process and reducing the cost. To date our platform has successfully been used to test 12 drugs, and vaccines against 8 different diseases. The company is founded by Robert DiFazio, a former Stanford R&D director with a PhD in immunology, and Juliana Hilliard, a former System1 Biosciences R&D lead with an MSc in bioengineering, both of whom have led drug discovery programs for years.
Parallel Universe, a Y-Combinator startup, helps developers utilize the most out of their hardware. With a server side stack developed for easy concurrency programming, you can ditch the extra servers and write simple multi-threaded code.

Parse lets developers build APIs for any website in seconds at fractions of a cent per call. Unlike traditional scraping tools that rely on slow, expensive headless browsers, Parse reverse-engineers websites' underlying network requests and generates optimized API endpoints automatically. This makes Parse 10-100x faster and significantly cheaper than browser automation, enabling use cases like real-time price monitoring, lead generation, and data integration that were previously impractical.
Parse offers cloud-based software developer kits that enable users to create apps for desktop, mobile, and embedded devices. Its product portfolio is comprised of Parse Core to save data in the cloud; make the app social; run custom app code in the Parse Cloud; schedule recurring tasks such as sending engagement emails, updating data, and long running computation; share data between platforms; and get a local datastore and Parse dashboard.
