What day by day does

day by day (legal entity Osmosia SAS, €308,502 capital) is a French bulk grocery retail chain founded in 2013 by Didier ONRAITA and David SUTRAT. It operates 100+ franchise stores across France, each run by an independent local merchant under the day by day brand, selling approximately 1,000 SKUs across grocery, hygiene, and household categories exclusively in bulk or consigned reusable containers. The chain is positioned as the first bulk sales operator in Europe and is built around a centralized model: a single warehouse (La Grange) in Dreux purchases, receives, and distributes goods in 5–25kg containers to the franchise network, with 70%+ of SKUs sourced from French production and ~25% without synthetic pesticides.

The company's core technology is a proprietary bulk-retail logistics and IT stack, including a lot-number traceability system that tracks every SKU from warehouse to shelf and a proprietary Indice de Réduction des Emballages (IRE) that quantifies packaging reduction per product (e.g., 95% on rice vinegar, 98% on flavored salt). A '100% vrac' mobile app supports shopping lists, store discovery, and product information, while L'éco-drive (launched January 2023) extends the model into online order-and-collect using reusable consigned containers across six cities. Marketing and distribution are multi-channel — social media, newsletter, in-store events, and content such as 118+ bulk recipes — but the primary commercial engine remains the franchise + central warehouse structure.

Revenue is generated from in-store retail (franchisee sales, on which Osmosia earns royalties), one-time franchise license fees, and a markup on goods flowed through the Dreux warehouse. Products are sold by weight or unit at pay-as-you-go pricing, 5–30% cheaper than equivalent pre-packaged goods, with consumers able to save up to ~€150/year per person. The stated customer segment is mainstream consumers seeking responsible, zero-waste consumption; no enterprise customers are disclosed. The firm is private, with no disclosed funding rounds, M&A, or revenue figures.

The retail offer is supported by centralized purchasing, dedicated bulk logistics from the Dreux warehouse, a mobile app for store discovery and shopping lists, and L'éco-drive, an online order-and-collect service that delivers orders in reusable consigned containers. The franchise model enables local independent merchants to run their own day by day stores under the Osmosia network.

Scale indicators7 records

Recent moves15 records

Expansion highlights10 records

Broad incumbents

• Carrefour: France's largest retailer, which has been expanding dedicated bulk sections in its hypermarkets. Represents the incumbent competitive threat that day by day must differentiate against through selection and zero-waste positioning.
• Intermarché: Large French retailer with growing bulk and local-production focus. Poses a competitive threat via scale and supplier relationships, though its bulk offering is incidental rather than central to its identity.
• Auchan: Major French retailer with bulk sections in its hypermarkets and a broader sustainability positioning. Competes with day by day on main grocery trip frequency while day by day captures smaller basket, zero-waste occasions.

Direct peers

• Naturalia: French organic and bulk grocery retailer with ~200 stores, mostly in and around Paris. Directly competes with day by day in urban bulk grocery retail with a similar sustainability-focused value proposition.
• La Vie Claire: French organic and bulk grocery chain with ~400 stores across France. Overlaps with day by day on bulk assortment, organic positioning, and franchise/affiliate store model.
• Satoriz: French organic and bulk grocery chain with ~60 stores concentrated in Eastern France. Directly comparable in bulk assortment and organic positioning, particularly in regional markets adjacent to day by day's footprint.
• Biocoop: France's largest network of organic and bulk-focused grocery stores with ~700 locations. Biocoop is a direct peer because it sells organic groceries with a heavy emphasis on bulk, targeting the same zero-waste-conscious consumer as day by day.
• Bulk Barn: Canada's largest bulk food retailer with 300+ stores. Although Canadian, this is one of the most direct international comparables for day by day's pure-play bulk retail model, store format, and product breadth.

Emerging players

• vrac.fr: Online bulk retailer specializing in zero-waste pantry, hygiene, and household products delivered in consigned containers. Comparable to day by day's L'éco-drive service and represents a digital-first competitive alternative.

Others

• moulin de la Veyssière: French artisanal flour mill and supplier selling bulk flours direct-to-consumer online. Sits in day by day's supplier ecosystem (similar to Moulins Familiaux partnership) and represents a partial overlap in the bulk ingredient category.
