Founder-led rental cost control · Norway
Rental charges, checked against the paperwork.
NivdoX reviews equipment-rental charges against the documentation surrounding the rental lifecycle.
We identify potential discrepancies worth investigating—and explain the available evidence without assumptions or inflated claims.
We’re looking for our first few contractor customers. Your first 5 rental reviews are free, with no obligation to continue.
Rental cost control for contractors
A focused review of the rental lifecycle.
We compare the available records around each rental and return concise findings you can assess. If no material discrepancies are identified, we say so.
Potential gaps flagged
Billing after documented off-rent, rental-period or rate discrepancies, missing credits, and unsupported or unusual charges.
Clear findings returned
If something is worth questioning, we show you exactly why. If the available records support the charge, we tell you that too.
Why work with NivdoX AI
Practical from the first review.
No portal, login, or complicated integration is required to start. The service is designed to prove its usefulness before you consider an ongoing review.
Founder-led
You deal directly with the person responsible for the work and the findings.
Prove value first
The first 5 reviews are free, so you can assess the service before making a commitment.
Evidence over assumptions
Missing evidence is identified as missing. It is never replaced with a guess.
No unnecessary software
We can start with a small set of documents using an agreed secure transfer method.
Human accountability
AI may assist the analysis, but NivdoX remains responsible for reviewing and communicating the findings.
About the founder
Hi, I’m Ola.
Before founding NivdoX AI, I worked as a B2B Security Advisor with Securitas, advising businesses on security needs and conducting on-site assessments.
I have since spent more than a decade working with guidance, training, and human behavior, and founded SAFE2DAY™, delivering professional training in conflict management and personal safety for people working in higher-risk environments.
That background shapes how NivdoX works today: be clear about what we know, protect sensitive information, minimize unnecessary risk, and never claim a result the evidence does not support.
AI is the technology behind the work. Trust, judgment, and accountability come first.
