Some truths only surface when someone knows where to look.
Sai Detective is a private investigation bureau based in Delhi, serving individuals, families and businesses across India since 2010. Matrimonial, corporate and background investigations — handled discreetly, documented properly.
Investigation work, organized by what you actually need answered.
Every engagement is scoped before it starts — you know what's being investigated, how, and what you'll receive at the end.
Matrimonial Investigation
Pre- and post-marriage verification — background, character, and existing commitments — before decisions that are hard to undo.
Background Verification
Identity, address, employment and character checks for tenants, domestic staff, partners, or new hires.
Corporate Investigation
Due diligence, vendor and partner verification, and internal investigations for businesses protecting their interests.
Employment Verification
Pre-employment screening and reference checks so hiring decisions are made on fact, not paperwork alone.
Asset & Financial Verification
Tracing assets and verifying financial claims in disputes, settlements, and business negotiations.
Surveillance & Cyber Investigation
Discreet physical surveillance and digital investigation, including employee theft and online fraud cases.
What you're actually hiring when you hire an investigator.
Confidentiality by default
Every case is compartmentalized — details are shared only with you, and only as far as you want them shared.
Evidence built to hold up
Reports are compiled to be usable in legal proceedings, not just informal peace of mind.
A team led by Vijay Singh
Founded in 2010 and run by an investigator with two generations of family background in the field.
Reach beyond Delhi
A pan-India network handles cases that cross city and state lines without losing continuity.
"I contacted Sai Detective for a matrimonial investigation. Their team handled the case with discretion and gave us clear, factual answers when we needed them most."
From first call to closed case.
Four stages, the same for every case regardless of size.
Confidential consultation
You describe the situation privately — by call, message, or in person. No case is opened without your go-ahead.
Case assessment
We evaluate what's realistically achievable, the method required, and give you a clear scope and timeline before work begins.
Investigation
Fieldwork, verification, or surveillance is carried out by trained investigators, with regular updates where appropriate.
Findings & report
You receive a factual, documented report — built to be understood on its own, without needing us to interpret it for you.
Start with a confidential conversation, not a commitment.
Tell us what you're trying to find out. We'll tell you honestly whether it's something we can help with — and what it would take.
