About Moriarty Services

Moriarty Services develops marketplace-native infrastructure for sellers — combining data analysis, listing systems, and platform research into a unified toolkit.

We build tools aligned with live marketplace behavior, leveraging search trends, historical sales, and token structure analysis to optimize listings for visibility and conversion. Our systems support marketplace ingestion, listing generation, and cross-platform performance modeling.

This site hosts utilities such as SkuLabelGen, our eBay Optimizer extension, and market analysis articles — all free and publicly available. It also serves as a hub for outbound platforms, including eBay, Mercari, GitHub, Thingiverse, and others.

Larger seller-facing, less libre systems — like our listing manager, optimizer, and crosslister — live at sellthru.net, where we’re developing structured workflows powered by LLMs and marketplace search logic.

Our goal is to bridge the gap between buyers, sellers, and large language models — building functional, search-aligned infrastructure for real-time ecommerce environments.
