The average saving on staff you no longer need to hire, redundant software, and everything you hand over to automation.
Your CRM
Your own system, shaped to your needs: the numbers that matter to you, the automation that fits exactly you. That is the next few years — arriving early.
Sound familiar?
A competitor cut their price at 3 a.m. You are finding out just now.
One of your listings went suppressed — and sat like that all night.
Your bestseller has 12 days of stock left. The reorder window was last week.
The owner report is built by hand again: exports, spreadsheets, copy-paste.
New-niche research has been sitting in the “when there is time” list for three weeks.
That is a morning without a system. And that was only five of the fourteen.
With SellerUp agents the morning looks different: by 7:00 the digest is already in your Telegram.
All that is left are the decisions that should not happen without you.
What we build
End-to-end engineering for marketplace sellers — built around your data, your operations, your goals. Not a SaaS subscription. A system that becomes part of your team.
Agents that watch listings, prices, inventory, ads, and supply chain — and act on rules you define. Plugged into the tools you already use.
We map your operations, find the repetitive bottlenecks, and ship pipelines that run on their own — keeping your team focused on strategy.
Internal dashboards, server-side platforms, integrations with marketplaces and suppliers. Built specifically for how your business actually works.
One system
Signals come in messy — prices, ads, stock, competitors. SellerUp agents sit in the middle: they decide what matters, route the work, and execute inside your guardrails.
Marketplaces and ad consoles — signals in, actions back.
Agents read the same data your team already trusts.
Built on the model that fits the task — not locked to one vendor.
Owner dashboards, price alerts and reports — in channels you already read.
Recent work
