About me

"You wouldn't sell a company to a business partner without checking the documents. Why would you sign a contract without checking the person?"

My name is Oana-Elena Sotir and I specialise in Open Source Intelligence and corporate due diligence. I studied Criminology and Criminal Justice at undergraduate level in England, and I am currently completing a Master's in Cybercrime, also in England — a rare combination that allows me to understand both traditional and digital risk.

I created Valthera Advisory because I have seen how exposed Romanian entrepreneurs are when they sign contracts without checking their partners. A 900 RON report can prevent a 100,000 RON loss.

All investigations are based exclusively on public and legally accessible sources. I do not use illegal methods, do not create fake accounts, do not purchase data. Each finding is documented with its source and date — these are not opinions, they are verifiable facts.

Why it matters
01
You don't really know who you're signing with
On paper, a company may seem solid. In reality, it may have hidden tax debts, 5 active enforcement proceedings, and an administrator who has been through 3 insolvencies. All of this is public record — but you need to know where to look.
02
The cost of not checking far exceeds the cost of the report
A standard due diligence report costs 900 RON. Recovering an unpaid advance through court proceedings can cost 10,000 RON and two years of your time. The maths is simple.
03
GDPR doesn't mean you can't check
Many believe that checking a potential partner violates GDPR. It doesn't. Legitimate interest (Art. 6(1)(f) of GDPR) allows you to verify a commercial partner before signing a contract. I document the legal basis for every investigation.
"A business partnership without due diligence is like a loan without a contract — you rely on blind trust in a world where trust is earned, not assumed."
— Oana-Elena Sotir, Valthera Advisory

My book

Do you truly know
who you're signing with?

I wrote this book for every entrepreneur, manager, or individual who has ever signed a contract based on blind trust — and paid the price. It is a practical guide about how to verify a business partner before taking on a risk.

It's not a technical book. It's the book I wish I had read before seeing, in practice, what happens when people sign without checking. After reading it, you will never sign anything the same way again.

Why "they seemed trustworthy" is not a verification strategy
What a professional investigator finds that you would never know to look for
Real cases: what happened when verification was skipped
The questions you should always ask before any contract or partnership
How to recognise a serious due diligence report and what it should contain
Why checking a partner is legal — and why so few people know this
