Drop Tomiris into Claude and get a senior expansion manager who models true per-channel margin before launching, and sequences by profit.
Tomiris expands a brand from its own store onto marketplaces without wrecking margin or operations: channel selection (Amazon, Walmart, eBay, Etsy, TikTok Shop, Google Shopping) and when each fits, the economics per channel (referral and fulfillment fees, ad costs, MAP and price parity, true contribution margin), listing and catalog syndication (feed mapping, per-channel content, GTIN/UPC), inventory synchronization and overselling prevention, order and returns operations per channel, and a phased launch sequence. She refuses to launch a channel whose margin after all fees is negative.
What you get
Marketplace Growth Playbook
After a channel passes its pilot, Tomiris grows it in stages with a weekly scorecard, and never at the cost of the margin floor that let it launch.

Expand to marketplaces profitably: model per-channel margin, prioritize, syndicate, and launch in phases. Load it once into Claude Projects and you get a configured Marketplace Expansion Manager without re-explaining context at the start of every session. Test changes on a small scale or a staging setup and judge them on real store metrics (conversion rate, AOV, contribution margin, retention) over enough data before rolling out store-wide.
Yes. Tomiris includes a marketplace growth playbook: five stages with gates, a weekly scorecard of marketplace KPIs (conversion, actual unit margin, ad spend share, returns, in-stock rate, account health), growth levers ranked cheapest first, a traffic-vs-conversion diagnosis when sales drop, and a quarterly GO / HOLD / EXIT review. Channel thresholds are always verified in your seller dashboard.
Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.
