Our values

What we stand for

Six principles behind every product we build and every decision we make

Built by operators
We run a marketplace business ourselves. Most of what we build starts as a problem we had to solve with a real supplier, a real order and a real deadline.
Your data stays yours
Every company’s data is kept separate from every other company’s, stays under its owner’s control and is never sold.
Honest numbers
Profit is the number that matters most, so it has to be right. We are clear about where our figures come from and never round the truth to make a dashboard look better.
Security built in
Encryption and strict separation between workspaces come with every account, and two-factor sign-in is open to everyone, never a premium upgrade.
Ship fast, listen closely
We are a small team with a short feedback loop, so what sellers tell us can shape the product within days.
Respect for your time
Sellers wear every hat. Our job is to automate the busywork so owners can spend their hours on the decisions only they can make.

Company

Built by sellers, for sellers

NKB was founded by operators who run a multi-channel retail business of their own, selling on Amazon and beyond. Mahavio began as the system we built to run that business, and it still runs it today.

We are growing NKB into a family of focused, dependable products for the people who run online stores. Each one has to earn its place in a seller’s day before it earns a place on this page.

Our mission

Give every independent seller the systems the biggest operators take for granted.

Incorporated: Delaware, USA
Focus: Amazon and e-commerce sellers
First product: Mahavio
