The infrastructure of autonomous French e-commerce.
Sellavi builds the technology layer that lets a solo operator run a multi-marketplace e-commerce business at the level of an SME — without hiring, without a warehouse, without technical complexity.
For investors watching where the next generation of European online commerce is being built: here's what we do, why now, and what we're planning.
E-commerce is fragmenting.
Online commerce no longer happens on a single merchant site. It happens on 5 to 10 marketplaces simultaneously, with scattered suppliers, shifting tax rules and compressing margins. This fragmentation creates a massive opportunity for orchestration tools — and a wall for sellers trying to do it by hand.
Multi-marketplace as the norm
In France, 70%+ of serious sellers operate on at least 3 marketplaces. Cdiscount, Amazon, Fnac, Rakuten and TikTok Shop together capture most of the B2C volume outside Shopify.
A renewed seller profile
The 2026 seller is no longer a kid learning from YouTube. It's a professional in career transition, a freelancer looking for extra income, or a small business diversifying its channels. More demanding, more solvent.
AI changes the unit economics
What required a team of 3-5 people in 2022 (catalog management, support, pricing) became operable by a single human in 2026, thanks to specialized AI agents. The seller's unit economics change radically.
French e-commerce has entered its phase of maximum operational complexity. Selling has become easy; operating has become impossible without infrastructure. That infrastructure is precisely what we're building.
Three partners, three expertises.
CORTEXIA GROUP SAS is led by three founders with strictly complementary skills: technology, business and growth. Each brings more than ten years of expertise in their field.
The extended team (backend engineers, AI engineers, product designers) works in tight collaboration, preserving iteration speed and technical quality without structural bloat.
One platform, six AI agents, zero friction.
Sellavi is a B2B SaaS platform that unifies the management of marketplaces and direct-dropshipping suppliers. At the core: six specialized AI agents continuously executing what a human cannot do at scale.
Catalog Manager
Keeps catalogs consistent across all marketplaces. Stock-out detection, price propagation, inconsistency alerts.
Pricing Optimizer
Adjusts prices continuously through three orchestrated strategies: reactive, predictive and algorithmic A/B testing.
Order Processor
Handles the full order cycle without intervention: payment, supplier, shipping, tracking, closure.
Customer Support
Answers the 80% of repetitive questions with order-history access. Smart escalation to humans.
Fraud Detector
Scores every order on behavioral, geographic and BIN signals. Cuts fraud 60-80% without blocking good customers.
Market Intelligence
Scans catalog opportunities, detects emerging trends, alerts on ranking drops.
Why Sellavi, not another one.
Three clear lines that define our position against ChannelEngine, Lengow, Onport or Channable: we are French, we are dropshipping-vertical, we are AI-native.
Direct-dropshipping specialization
We are not a generic feed manager. We are an end-to-end infrastructure for stockless commerce: prepaid supplier payment, deal negotiation, logistics supervision, GPSR compliance.
