Frequently Asked Questions

What kind of Information would you need to start investigating a case?

We expect our clients to provide all kinds of detailed information pertaining to the case. Even minute details give big breakthroughs, so nothing is irrelevant in investigative operations. To begin with, you can share the phone numbers, address, office locations, social media accounts as far as you know, videos or anything else that you feel will be helpful for us. We start from the very basic and proceed in a systematic manner to make sure that our inputs are accurate, to avoid any goof-ups during the process.
The information’s that you will be providing will be confidential and we never compromise on that. Suppressing vital information will only complicate the case and make it more time-taking. Considering our track record of working with big clients, you can be rest assured that every detail that you provide will be used only on the specific case and not be leaked anywhere. Our experts will check, cross-check and verify all inputs and then start working . So, you do not have to worry about anything pertaining to data safety and confidentiality.

What will be the cost of investigation?

The cost of investigation depends on the complexity of the case. Depending on the number of people involved, surveillance equipments used, transportation cost, risks and other intricacies we decide on the expenses that the company will need to bear on a certain case. Based on that we will provide you a rough estimate on what would be the possible cost in the case.
Since our investigators often go through very critical situations that involve life threat, we have a responsibility in providing them safe accommodations and food. Any surveillance work requires hours of data analysis, behavioral analysis and identifying a pattern by which the crime is done. Unlike any other work, it is stressful and involves a lot of legal risks as well. So, our cost estimates will take into account, all the challenges involved in a case and then we decide on the final amount.

What are the things I must know before choosing the right agency?

Before choosing an agency you must look into their experience, public reviews, charges, time taken in solving the cases and reliability among other things. This is because in the investigative world, each case is unique. So, there is no one size fits all approach that anyone can take while dealing with it. As a client, you need to talk face to face and find out whether the agency is looking to go deeper into the case. Quality investigation agencies will provide you enough details about their processes so that you can take a decision.
While choosing an agency see whether they have a good reputation in the corporate and individual circles. This is to avoid organizations who will keep on dragging a case to make a few extra bucks, jeopardizing your prospects. Always select a company that has a strong and passionate team of spies, who would make sure that your data safety is not compromised. This will help in a faster progression of the case and allow you to get closer to the actual result.
