Stop waste. Sell smarter.

Kaizen Seller combines generative AI with battle-tested lean principles to turn surplus inventory into revenue — across every sales channel.

$163B

Inventory discarded yearly that could be reused

4.9M

Tons of e-commerce returns landfilled annually

Potential when AI meets circular commerce

Our mission

Stop waste by putting data and automation into the hands of sellers and asset managers. We use machine learning and continuous improvement to identify recoverable value, automate listings and workflows, and make circular commerce profitable and scalable.

Our goal is to make it easy — and lucrative — for people and businesses to keep products in use longer. Every unit resold is one less in a landfill.

Principles that guide us

Inspired by the Toyota Production System and adapted for the AI era.

Kaizen — Continuous Improvement

Small, relentless improvements compound over time. Every feature, every algorithm refinement, and every workflow tweak is driven by this philosophy.

Jidoka — Built-in Quality

Automation with a human touch. Our AI generates listings and detects products, but humans stay in the loop to validate, correct, and improve.

Flow — Eliminate Waste

We remove friction from the selling process. Batch uploads, multi-channel sync, and AI categorization keep inventory moving instead of sitting idle.

I am fascinated by Kaizen, jidoka (autonomation), and the Toyota Production System — principles that guide continuous improvement, built-in quality, and human-centered automation. Those ideas shape how I build tools and businesses.

At my other company, Chase Surplus, Inc., I applied these principles to operations and tooling. We list millions of dollars of inventory every year and work with some of the largest asset recovery companies in the world to prevent unnecessary disposal. The problem is enormous: roughly $163 billion worth of inventory is discarded each year that could be reused, repaired, or resold.

I believe the combination of machine learning and Kaizen is the way forward. By bringing rigorous, iterative improvement together with generative AI, we can reduce waste, promote a circular economy, and create value for everyone involved.

I personally coded the very first live version of Kaizen Seller to ensure the product reflects that vision and practical operational needs. Building the first release myself let me fully utilize my expertise so the tool can be useful to real sellers from day one.
