During 2018, The Boring Company was spun out into a separate corporate entity with 6% of the equity going to SpaceX, less than 10% to early employees, and the remainder of the equity to Elon Musk. 2019–present: Starship, Starlink, and first crewed launches In January 2019 SpaceX announced it would lay off 10% of its workforce to help finance the Starship and Starlink projects. Construction of initial prototypes and tests for Starship started in early 2019 in Florida and Texas. All Starship construction and testing moved to the new SpaceX South Texas launch site later that year. In May 2019 SpaceX also launched the first large batch of 60 Starlink satellites, beginning the deployment of what would become the world's largest commercial satellite constellation the following year. The company raised a total of US$1.33 billion of capital across three funding rounds in 2019. By May 2019, the valuation of SpaceX had risen to US$33.3 billion and reached US$36 billion by March 2020. A major milestone was achieved in May 2020, when SpaceX successfully launched two NASA astronauts (Doug Hurley and Bob Behnken) into orbit on a Crew Dragon spacecraft during Crew Dragon Demo-2, making SpaceX the first private company to send astronauts to the International Space Station and marking the first crewed orbital launch from American soil in 9 years. The mission launched from Kennedy Space Center Launch Complex 39A (LC-39A) of the Kennedy Space Center in Florida. On 19 August 2020, after a US$1.9 billion funding round, one of the largest single fundraising pushes by any privately held company, SpaceX's valuation increased to US$46 billion. In February 2021, SpaceX raised an additional billion in an equity round from 99 investors at a per share value of approximately $420, raising the company valuation to approximately billion. By 2021, SpaceX had raised a total of more than billion in equity financing. Most of the capital raised since 2019 has been used to support the operational fielding of the Starlink satellite constellation and the development and manufacture of the Starship launch vehicle. By October 2021, the valuation of SpaceX had risen to US$100.3 billion. By 2021, SpaceX had entered into agreements with Google Cloud Platform and
