Jaipur head office · pan-India coverage
Whether you need a detective agency in Jaipur, a private detective in Delhi, or investigation support anywhere in India, Full Circle delivers answers you can act on. Founded by Kishore Kumar Nagi, we have completed more than 5,000 cases across matrimonial, corporate, personal and financial investigation since 2001.
Clients come to us when something does not add up — a marriage proposal that looks too good, a spouse whose routine has changed, an employee who is costing the business money, or a property that may not be what it was described as. We find out, discreetly, and give you documented proof.
Every case is handled personally by our chief investigator. You never deal with a call centre, you never repeat your story to a stranger, and your identity is never revealed to anyone.
Comparing us against others? Good. We wrote a scoring guide for exactly that: how to compare detective agencies in Jaipur — eight checks you can run on any firm in ten minutes, including this one.

Why clients choose us
Six reasons families and businesses across India trust us with the questions they cannot ask anyone else.
Kishore Kumar Nagi personally scopes, runs and reports every case. No junior staff, no call centre, no retelling your story.
Your name is never disclosed. We contact you only on the number and in the time window you choose, and case files are never shared or reused.
Dated reports with photographic and video documentation, prepared so your advocate or your family can rely on it.
Jaipur and Rajasthan handled directly by our own team; Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Kolkata, Pune and Ahmedabad by our own investigators in each city.
Our investigators also work in the USA, Canada, the UK, Australia and across the Gulf, so verification abroad is handled the same way.
You get a written scope and a fixed fee before any work begins. No hourly surprises and no demand for more money halfway through.
Simple, transparent process
Four simple steps from your first call to the final report.
Call or WhatsApp us at any hour. Tell us what you need to find out — a few sentences is enough. We will tell you straight away whether it can be established, how long it is likely to take and roughly what it will cost.
Nothing is charged for this conversation and you are under no obligation to proceed.
You receive the objectives, the method, the cities involved, a realistic timeline and a fixed fee — in writing, before anything begins. If the case later needs to grow, we come back and ask rather than adding charges.
A part payment starts the work; the balance is due when the report is ready.
Our team begins work, usually within 24 to 48 hours. Depending on the case this means discreet surveillance, verification at employers and institutions, record checks, enquiry in the locality and photographic documentation.
You are updated at the intervals you choose, through the channel you choose. If something important emerges early, you hear it immediately.
We talk you through the findings first, then send a dated written report with the supporting photographs, video stills and records. Everything is laid out so you — or your advocate — can use it immediately.
If you need further work after reading it, we will tell you honestly whether it is likely to add anything.

Global investigator network
Full Circle has its own investigators in the United States, Canada, the United Kingdom and Australia, and a network of investigators across the Gulf — the UAE, Saudi Arabia, Qatar, Kuwait, Oman and Bahrain. That means background verification, matrimonial checks and corporate due diligence can be carried out on the ground in those countries, within local law — not only in India.
For NRI families this matters. If a proposal, a business partner or a relative is abroad, we can check both sides: the India position and the overseas one. One agency, one point of contact, both countries.
Living abroad and need something checked here? Start with private investigator in India for overseas clients, NRI groom and bride verification or checking someone you met online.

Pre matrimonial investigation verifies what a marriage proposal claims before you commit — the person's job, income, education, family background, property, character and whether there is any previous marriage. It is one of our most requested services and usually takes five to ten working days. Read more on our pre matrimonial investigation page.
No. Discretion is the core of our work. We never approach the subject or their household, observation is carried out from a distance, and enquiries are structured so nobody can tell who is asking or why. In 25 years we have built our reputation on this.
A background or pre matrimonial check in one city usually takes five to ten working days. Surveillance can take anywhere from two days to four weeks depending on what needs to be established. Post matrimonial cases typically run two to five weeks. You get a realistic timeline in your written quote.
Yes. Our reports include dated observation records, photographic and video documentation and copies of supporting records, prepared so your advocate can use them in matrimonial, civil or recovery matters. Tell us at the start if the case is headed to court so we can document accordingly.
