Sellavi is the French platform that automates multi-marketplace selling for e-commerce entrepreneurs. Our mission: let any seller generate an online income without touching stock, without technical complexity, and with the permanent support of specialized AI agents.
The problem we solve
Selling on several marketplaces (Cdiscount, Amazon, Fnac, Rakuten, TikTok Shop…) is an operational nightmare for 90% of sellers. Syncing stock, updating prices on each platform, processing orders one by one, handling returns, support, disputes… most of the time goes into zero-added-value tasks. The seller burns out on operations, not on growth.
Our answer
Sellavi centralizes everything in one platform:
- Unified catalog — your products from our partner suppliers are published in a few clicks to the marketplaces of your choice;
- Automatic sync — stock, prices and orders sync in real time, both ways;
- Prepaid wallet — an internal wallet funded by card that automatically pays suppliers;
- 6 AI agents — market analysis, price optimization, fraud detection, customer support, catalog supervision, stock-out alerts.
The seller sets their margin, funds their wallet, picks their products. Sellavi handles the rest.
Why we exist
We built Sellavi because we lived the pain of multi-marketplace dropshipping ourselves: scattered tools, manual CSV exports, suppliers that don't talk to each other, marketplaces changing their rules every quarter. To scale an e-commerce business, you either hire a whole team or accept working 80-hour weeks on logistics.
Neither is viable for a solo entrepreneur or a 2-3 person team. Sellavi is designed for that profile: someone who wants to build a solid e-commerce income without building a logistics SME.

The founding team
CORTEXIA GROUP SAS is the company behind Sellavi, founded by Samy HERZI and Jeremy Avital. The team is entirely French-speaking and based in France. Our e-commerce director, William Sellam, oversees partnerships with marketplaces and suppliers.
We are a small team that puts execution quality before marketing: no flashy fundraising, no massive ad spend. Our growth comes from customer word of mouth and the technical solidity of the platform.
Our values
Sovereignty
Our technical stack is French and European. No critical dependency on non-EU providers for your data. Everything is hosted in Europe, under GDPR.
Transparency
Prices are public and fixed (€99 / €699 per month). No opaque sales pricing, no hidden cost. The T&Cs can be read in 5 minutes.
Total automation
Our obsession: the seller should touch nothing after the initial setup. If you spend more than 30 minutes a day in the interface, we failed somewhere.
Quality before speed
We don't ship a feature until it holds up in production. Better one solid feature than ten hacked together.
What's next?
Our public roadmap: extension to 10+ marketplaces, the German marketplace Otto, listing-optimization AI agents, an affiliate program for resellers. Contact us to learn more or book a demo.
