SpaceX designs, manufactures and launches advanced rockets and spacecraft. The company was founded in 2002 to revolutionize space technology, with the ultimate goal of enabling people to live on other planets. SpaceX has gained worldwide attention for a series of historic milestones. It is the only private company capable of returning a spacecraft from low Earth orbit, which it first accomplished in 2010. The company made history again in 2012 when its Dragon spacecraft became the first commercial spacecraft to deliver cargo to and from the International Space Station. SpaceX successfully achieved the historic first reflight of an orbital class rocket in 2017, and the company now regularly launches flight-proven rockets. In 2018, SpaceX began launching Falcon Heavy, the world’s most powerful operational rocket by a factor of two. As one of the world’s fastest growing providers of launch services, SpaceX has secured over 100 missions to its manifest, representing over $12 billion on contract. These include commercial satellite launches as well as US government missions. SpaceX’s Dragon spacecraft is flying numerous cargo resupply missions to the space station under a series of Commercial Resupply Services contracts. Dragon was designed from the outset to carry humans to space and will soon fly astronauts under NASA’s Commercial Crew Program. Building on the achievements of Falcon 9 and Falcon Heavy, SpaceX is working on a next generation of fully reusable launch vehicles that will be the most powerful ever built, capable of carrying humans to Mars and other destinations in the solar system.

What we are building: Nullgen is a localized data loss prevention (DLP) browser extension and administrative platform. The product operates on a freemium model, with the premium enterprise and education tiers offering centralized management, zero-touch MDM deployments, and tamper-proof policy enforcement. The hard problems we are solving: - Enterprise Shadow AI: Employees constantly leak proprietary company code and sensitive financial data into unvetted public LLMs. We stop this data loss locally before the prompt ever hits the network. - K-12 Academic Integrity: Students easily bypass traditional DNS school filters to use AI for essays and tests. We provide district IT administrators with an impenetrable, device-level roadblock. - Privacy-Preserving Security: Traditional DLP software requires routing traffic through third-party servers. Because our custom ML model runs entirely on the user's local device, zero payload data ever leaves the machine, ensuring total data privacy and massive reductions in cloud compute costs.
