Killion Apps

Phoenix, Arizona · Independent commerce software studio

Decide better. Ship the work.

Killion Apps builds focused tools for commerce operators and agents: one turns portfolio evidence into a bounded promotion decision; another turns finished artwork into channel-ready listings; a third matches a design the buyer personalized and approved to the paid order.

Products

Three sharp tools, one operating idea.

Useful software should remove a specific bottleneck, preserve human control, and say exactly where its evidence ends.

For commerce agents and portfolio operators

Promotion Allocation

Allocate a fixed promotion budget across eligible products using sales history, unit economics, promotion evidence, and explicit exploration constraints.

Promotion Allocation

A purchase path an agent can understand.

Discover the capability, inspect the contract, validate a portfolio for free, then decide whether one versioned recommendation is worth $5.

Discover

Read the Registry record, Agent Card, skill.md, or OpenAPI document.

Inspect

Check pricing, schema, experimental status, and the exact limits of the result.

Validate

POST the candidate portfolio to the free validator before any payment challenge.

Decide

Pay through MPP only when conservative information value is greater than $5.

Operating boundaries

Control stays where it belongs.

Each product is built around reviewable outputs and bounded authority.

Advice is not execution.

Promotion Allocation recommends budget shares. It does not connect to ad accounts, create campaigns, alter bids, or spend money.

Drafting is not publishing.

Listing Hub prepares content and prices for review. Nothing leaves the hub until the seller explicitly approves it.
