Rocket Close, previously known as Amrock LLC and Title Source, Inc., operates as a U.S.-based provider specializing in title insurance, property appraisal, and settlement solutions. It functions as a fully owned subsidiary of Rocket Mortgage, with its main office located in Detroit, Michigan.
History
The company was established in 1997 following the purchase of Campbell Title Insurance Company of Michigan. Operating initially under the name Title Source, it quickly grew to serve clients nationwide by optimizing title and settlement processes related to mortgages. In 1999, the software corporation Intuit acquired both the company and Rock Financial; Jeff Eisenshtadt, the CEO, continued to oversee expansion efforts. Three years afterward, Eisenshtadt partnered with private investors to buy back the firm from Intuit.
In 2018, the business underwent a rebranding to become Amrock. Its parent organization, Rocket Companies, launched an initial public offering on the New York Stock Exchange in 2020. Subsequently, in 2025, Amrock adopted its current name, Rocket Close.
Trade secrets lawsuit
In 2016, Amrock initiated legal action against analytics company HouseCanary concerning a 2015 licensing agreement tied to real estate appraisal software and accusations of misappropriating trade secrets. A Texas jury decided in favor of HouseCanary in 2018, granting damages totaling approximately $706 million—a record verdict for Bexar County.
Amrock contested this ruling by submitting evidence suggesting fraudulent conduct by HouseCanary and petitioned for the verdict to be reversed. Despite multiple appeals and motions for a retrial, courts initially upheld the decision and mandated that Amrock pay close to $740 million. This litigation ranked among the largest trade secret disputes in the United States.
Additionally, HouseCanary filed suit against Quicken Loans; testimony from former HouseCanary employees supported Amrock’s allegations regarding defective technology and collusion. Nevertheless, a judge denied Amrock’s motion for a new trial in 2019. The following year, a Texas appellate court overturned the jury’s verdict due to errors found in the jury instructions.
