About
We built the tool we wanted to trust.
Vendlen is made by people who spend their own money on Amazon Ads every day. That is the only credential we have, and it is the one that decided how the product behaves.
Vendlen is a self-service SaaS application for Amazon sellers. Each customer creates their own Vendlen workspace and authorizes their own Amazon seller account.

Spending your own money changes the design.
An optimizer that cannot explain itself is easy to build and hard to live with. When the account being changed is yours, you stop wanting a score and start wanting a sentence you can argue with. Four commitments came out of that, and each one is visible in the product rather than stated here.
- 01A decision has to show its evidenceEvery Decision Brief states the action, the reason, the rows the reason rests on, the period they were read at, and the scope. You can disagree with it in the same place you would accept it.See what a brief carries
- 02A rule has to be readable a month laterRules state what must be true, what they will change, and the boundary they may not cross. Every run keeps what it decided and what it delivered, rule by rule.See how a rule is written
- 03A change you can see coming, and read backA run can be previewed before it happens, and what it did is recorded afterwards, rule by rule. Whitelist protects the terms you do not want Automation to negate.See how delivery is arranged
- 04A cost keeps its own nameAmazon does not bill one fee. It bills freight, duty, storage, fulfilment, transfers, clawbacks and reimbursements. Collapsing them into one number is how a product looks profitable right up until it is not.See the fee breakdown
What Vendlen is not.
Not an agency
Nobody here manages your account for you, and nobody here is running your competitors' accounts at the same time. The product is the whole relationship.
Not a black box
There is no single optimization switch, and no score standing in for a reason. If a change cannot be explained in a sentence with numbers under it, it does not ship.
Not a claim we cannot show
No customer counts, no outcome percentages, no case studies — none of them can be sourced yet. When they can, they arrive with the method beside them.

Read the reasoning, then decide.
Start on the trial and look at a Decision Brief against your own account. That is the fastest way to tell whether this was built by someone who has your problem.
