I contacted these guys based on a recommendation from an attorney and family friend, and the results were spectacular. Surveillance and other “tools of the trade” did the job, and I did obtain my answers. The rest is highly private so I apologize, but what I can say is if you wish to have a company that genuinely cares about your concerns, the outcome of your situation and sets expectations from the initial consultation, then tio square is whom you should call. read less

I just want to start by stating that kieffer is one of THE MOST professional human beings I have ever done business with! Literally he wrote me back within and hour and we started off the process basically right away.

What services do you offer?
TIO Square covers a wide range of Investigative Services. Contact us to discuss your specific needs.
A Private Investigator, also referred to as a Private Eye or Private Detective, is an individual or a group of Licensed Professionals hired to gather evidence on personal or business matters as well as ongoing legal and criminal proceedings. They are most commonly hired for surveillance services (infidelity, insurance, missing persons), to locate records or conduct thorough background researches. Private Investigators also locate hard to find subjects, conduct thorough interviews, and gather evidence for legal proceedings.
How much does hiring a private investigator cost?
While searching for a Private Investigator to hire in New York City, you might be surprised to find that there isn’t a specific industry-wide rate. Prices often depend on which services you request, difficulty in obtaining the evidence, and expenses involved. Here is a brief explanation of Private Investigator rates:
Hourly rates: Hourly rates for a Private Investigator in the New York area vary depending on the specific type of investigation and difficulty in executing the request. Most investigators will offer a block discount if you book several hours at once, which is recommended when ordering surveillance services.
Retainers: A retainer is a down payment for an investigator’s work. They can vary based on your needs. Most Private Investigators will charge against your retainer, and refund any unused amount.
Expenses: Investigators can also incur expenses while they are engaged in following the target of the investigation, and some of the most common expenses are mileage, tolls and parking related fees.
Additional and Unforeseen Expenses: Your investigator will contact you prior to proceeding with additional expenses, such as exceeding the budgeted time limit due to an active target, or any other expense that might arise in the execution of the investigation.
Do you have to be licensed?
Yes. To conduct investigations in the state of New York, you must be licensed by the New York State Department of State, and maintain a bond. Our License number is 11000208411, and we are bonded.

What are your rates and are you licensed?
TIO Square Inc. provides investigation services in New York City and other locations around the New York area, including Long Island and Westchester. Cost of services depend on the specific scope of the project and the hours estimated. Our the New York State Department of State provides the license required for PI companies in New York. Many factors are taken into the estimated cost for investigations provided to our client, such as travel cost, and hourly rates.
Do you work with the police?
Yes. Sometimes it is important to seek the assistance of the local police department, to investigate criminal cases or for further information on a current ongoing case. Police departments in New York City often offer a great amount of help and information to investigators, and the general public, needed for cases under investigation. An example is in the case of a vehicle accident, where it would be advantageous to speak with the responding police officers who were present at the scene on the date of loss, even if the accident occurred months ago, or even a few years back.
Do you help with security guard services in New York?
Although other PI companies in New York offer security guard services, we currently do not offer security guard coverage or training. See our website for additional information if you need assistance with shrinkage, or need assistance with suspected employee theft cases. To investigate theft cases we recommend undercover investigations. Contact us for more details.
Do you offer security guard training services for the 8 or 16-hour license in New York?
We currently do not provide security guard license training services. See our website blog for additional information on obtaining a New York State (and other states) PI License.
