Global private intelligence spy agencies
Private intelligence agencies are usually co-founded by a number of private
                                    capitalists, investors, or intelligence professionals with sufficient experience.
                                    These agencies may obtain business from corporate or individual clients and provide
                                    a variety of intelligence services to their clients to meet their needs. These
                                    clients can be corporations, law firms, private investigative agencies,
                                    non-governmental organizations, government agencies, individuals, etc. 
The
                                    main task of a private intelligence agency is to collect a large amount of
                                    information through various sources such as news, literature, the Internet, surveys,
                                    tracking, surveillance, and theft. This information may include assets of companies
                                    and individuals, business plans, trade secrets, personal information, and
                                    politically sensitive information. 
Private intelligence agencies also use a
                                    number of technical means to improve the quality and quantity of intelligence
                                    information, such as technical surveillance, data mining, cross-platform analysis,
                                    and big data analysis. 
Private intelligence agencies often collaborate with
                                    other organizations to achieve their missions. These organizations include other
                                    intelligence agencies, legal enforcement agencies, strategic consulting firms,
                                    security companies, etc. 
Private intelligence agencies' clients may also
                                    come from these organizations. Such cooperation can help intelligence agencies gain
                                    greater access to resources, technology, and information, and can enhance mutual
                                    trust and cooperation among organizations.

The
                                        self-proclaimed hedge fund manager denied any connection to Surefire, but NBC
                                        reported that company calls were redirected to Wohl's mother.

AIQ is a data intelligence company
                                        specializing in data intelligence, founded in 2013 and headquartered in Canada, as
                                        well as having offices on the west coast of Canada. 
As a data intelligence
                                        company, AIQ focuses on helping clients develop better marketing and political
                                        strategies, as well as providing them with better data analysis and applications.
                                        AIQ had been a low-profile company until the UK's 2016 Brexit referendum thrust it
                                        into the spotlight. 
AIQ was accused of failing to keep personal data secure
                                        and not being transparent about its actions. Facebook was also implicated in the
                                        incident because AIQ was using Facebook to deliver information to voters. 
During
                                        the UK Select Committee hearing, a Facebook executive said that Vote Leave and
                                        BeLeave were targeting the exact same audience on Facebook through AIQ. This has
                                        caused widespread concern and has put AIQ's reputation in great jeopardy.

Hakluyt is a privately held
                                            intelligence and security consulting firm based in London, UK, founded in 1995. The

                                            San Francisco, Tokyo, Frankfurt, Singapore, Mumbai, Chicago, Washington, D.C. and
                                            Sydney. 
The company's name comes from the 16th century English explorer
                                            Richard Hakluyt, a name that signifies the spirit of exploration and discovery of
                                            new things. Clients include Shell and BP. 
The interest in Hakluyt, which has
                                            been described as a "spy's retreat," began after the death of British MI6 informant
                                            Neil Heywood in 2012. 
Hakluyt's business consists primarily of providing
                                            intelligence gathering, analysis, assessment and security consulting services to its
                                            clients. Hakluyt's client base encompasses businesses, government agencies and
                                            non-profit organizations across multiple industries and geographies, and Hakluyt's
                                            services are targeted at clients who require highly confidential and reliable
                                            intelligence and consulting services, particularly those operating in complex and
                                            sensitive environments. 
In addition to some of the major clients mentioned
                                            above, Hakluyt has provided intelligence services for a number of major events. 
Hakluyt's
                                            background has been of great interest. One of the company's founders is Christopher
                                            James, who served for many years at MI6 and was part of the agency's special units
                                            in Iran and Sudan. Another of Hakluyt's founders is Michael Davies, who served as a
                                            senior officer at MI6 in the UK. Most of Hakluyt's key management members also come
                                            from MI6 or other British intelligence agencies. 
However, Hakluyt does not
                                            publicly acknowledge that it is an intelligence company or that it is affiliated
                                            with the British government or other intelligence agencies. Some believe that
                                            Hakluyt is a powerful tool for the British government in the international
                                            intelligence arena, as the company has a high level, highly professional
                                            intelligence team with a wealth of intelligence resources and access.

                                            British tycoon Vincent Tchenguiz. 
Black Cube provides intelligence, evidence
                                            and consulting services for cross-jurisdictional legal and white-collar crime cases.
                                            Its clients include primarily high net worth individuals, oligarchs and corporations
                                            around the world, and Black Cube has uncovered fraud, bribery, money laundering,
                                            corruption and asset loss. In addition the company has uncovered high-level
                                            corruption in Italy, Panama and Mexico. It is estimated that Black Cube has managed
                                            to track down and recover billions of dollars in hidden assets around the world.
                                            
However, according to the Wall Street Journal, Black Cube's methods are not
                                            very clever, but rather its signature is recklessness and forcefulness. 
In
                                            2019, agents were exposed for smearing financier George Soros. 
In 2016, two
                                            employees were arrested and sentenced to probation in Bucharest for espionage.
                                            
Black Cube's work with Tchenguiz involved lawsuits, countersuits and
                                            settlements, and its agents were later subpoenaed for using fake IDs to meet with
                                            actress Rose McGowan and extract information for Harvey Weinstein.
