How to Build (or Rebuild) Your Marketplace: A Strategic Guide for Clear-Eyed Operators

Kevin M.

Clear-eyed? What does that mean exactly?

In 2025, launching a marketplace is no longer the hypergrowth story it was during the pandemic boom. It's a question of operational performance, ongoing maintenance, strategic alignment, and above all, genuine digital maturity. Very few organisations are starting from scratch on a project of this scale today.

That said, if this is the path you're choosing, this guide is for you. Whether you're a first-mover or a business already deep in an omnichannel journey, you want to understand what today's consumers actually expect, and take back control of a model that has become more demanding than ever. Let's get into it.

Building a Marketplace in 2026: From Experimentation to Consolidation

Between 2015 and 2021, launching a marketplace was shorthand for dynamism and innovation. Retailers, manufacturers, brands, and pure players all saw it as a fast track to growth and diversification.

It was a digital gold rush. Every roadmap referenced it, more as a proof of concept than a profitable operating model.

But the context has shifted entirely. Building a marketplace in 2026 is no longer an experiment. It's a precision operation. It's a considered response to a complex, mature, and in some sectors oversaturated market.

Why?

  • Third-party sellers have become demanding, because they're being approached from every direction.
  • Customers benchmark your service levels against Amazon and other category leaders.
  • Regulation (VAT compliance, extended producer responsibility, consumer protection law) demands a new level of rigour.
  • Internal teams are drowning in fragmented tools with no clear orchestration layer holding it all together.

The consequence: you no longer simply "launch" a marketplace. You (re)build its foundations, sometimes starting from an existing e-commerce infrastructure through replatforming, with method, precision, and strategic alignment.

Why Build a Marketplace at All in 2026?

Before looking at platforms and tools (Uppler, Izberg, Wizaplace...), the real question is a strategic one:

"Why this marketplace? What business objective does it actually serve?"

Typical scenarios where a marketplace makes sense:

The B2B distributor looking for operational efficiency
Goal: consolidate orders from regional points of sale while controlling procurement costs. The marketplace becomes a tool for rationalisation and standardisation.

The brand that wants to expand its range without taking on additional logistics
Goal: broaden the catalogue (apparel, garden, lighting) through partners, with no added inventory or financial risk. A growth lever that doesn't inflate fixed costs.

The industrial network that wants to pool purchasing
Goal: digitalise and centralise procurement across its members while strengthening collective negotiating power. The marketplace becomes both a community platform and a transactional engine.

The service business structuring a distributed offering
Goal: unify customer journeys (installation, advisory, maintenance) across a network of service providers. A services marketplace where the value proposition lives in execution quality.

In every case: the marketplace is a means to an end, never the end itself. The next step is choosing the right model.

Which Marketplace Models Actually Work?

Use cases are diversifying, but the winning models follow proven logic. Here are the three best-performing formats right now.

The Range Extension Marketplace

Widely used in retail, this model allows businesses to broaden their online offering across additional channels without impacting inventory or cash flow.

Why it works: it improves conversion rates, captures complementary purchase intent, and creates a halo effect on the core range. According to Mirakl, range extension marketplaces generate an average of +36% incremental revenue in the first year alone.

Compelling figures, but who does this model actually work for?

Real-world examples:

  • Decathlon: +20% of its online range through third-party sellers in nutrition, outdoor sports, and more.
  • Conforama: 40% of its e-commerce catalogue powered by the marketplace.
  • Leroy Merlin: expanded into smart home and décor through third-party partners.
  • La Redoute: over 50% of e-commerce revenue now generated through third-party merchants.

This model does, however, require rigorous seller selection to protect brand integrity, consistent and SEO-optimised product listings, and a coherent fulfilment experience across every channel, including tracking, customer service, and returns, all aligned with retail-grade standards.

The Supplier Marketplace

Used by cooperatives, franchise networks, and multi-site groups, supplier marketplaces centralise procurement flows through a curated panel of approved suppliers.

Why it works: this model typically delivers a 15 to 25% reduction in procurement costs, better visibility over order volumes, and meaningful process standardisation.

Real-world examples:

  • InVivo: a shared procurement platform for its agricultural cooperatives.
  • Best Western: digitised group purchasing for its hotels, delivering an 18% cost reduction.
  • Rexel: streamlining professional procurement through its marketplace.
  • ManoManoPro: 20% annual growth driven by its B2B segment.

This model comes with specific success conditions. It demands meticulous access rights management (user permissions, ordering rules) given the volumes involved. The catalogue must be standardised with clear pricing tiers, and tight synchronisation with ERP and OMS systems is non-negotiable.

The Services Marketplace

A model that continues to gain ground by combining product sales with human-delivered services: premium delivery, assembly, installation, expert advice.

Why it works: a services marketplace increases perceived value, average order value, and customer loyalty. McKinsey notes that adding a service layer increases conversion rates by 25% and reduces returns by 30%.

Real-world examples:

  • Boulanger: installation, repair, and technical support services.
  • Maisons du Monde: interior design coaching and home assembly.
  • Manutan: industrial assembly services.
  • Leroy Merlin and Castorama: integrated fitting services for bathrooms and kitchens.

That said, this model is not for the inexperienced. Combining products and services in a single marketplace requires intensive vetting, contracting, and monitoring of service providers, seamless integration of service booking into the customer journey, and robust management of scheduling, SLAs, and disputes.

These models work because they serve a clear strategy, adapted to a context where a marketplace is no longer a bet on the future but a precision instrument. The real challenge is orchestrating all of this without losing operational efficiency. That's where everything is won or lost today.

Nowadays, Technology Is No Longer the Obstacle

Orchestration Matters More Than the Platform

The market offers robust solutions: Wizaplace, Izberg, Uppler, Mirakl, Spryker, all with headless modules, APIs, and PIM/ERP connectors.

The question is no longer "which tools?" It's how to integrate them effectively into your existing tech stack.

In 2025, a high-performing marketplace is built on:

  • Seamless PIM integration for consistent, high-quality product data
  • ERP/OMS connectivity to manage inventory and orders in real time
  • Compliance tooling to automate VAT, invoicing, and eco-contribution obligations
  • Multichannel logistics for a genuine 360-degree customer view
  • A fast, responsive front end that's consistent with the brand identity

That may sound like a long list. It is. But this is the reality of a genuinely complex model — one that is far from a simple technology stack, but rather the art of making all those layers invisible in service of an exceptional customer experience.

The Pillars of Building (or Rebuilding) Your Marketplace in 2026

Technology alone is no longer enough. You need a solid architecture, managed with rigour and aligned around clear objectives.

Business strategy: define the marketplace's role within the broader ecosystem, settle on a viable commercial model (commission, subscription, or hybrid), and articulate a genuinely differentiated customer promise.

Systems architecture: choose between a standalone or integrated platform, govern your core data (products, pricing, inventory) properly, and ensure compatibility with existing infrastructure.

Operations and governance: structure onboarding, quality control, and dispute management, and ensure tight alignment between IT, commercial, and legal teams.

Compliance: build in your legal obligations from day one (VAT, eco-contributions, product liability) rather than retrofitting them later.

In 2025, failures rarely come from the technology. They come from strategic ambiguity, weak governance, and a chronic underestimation of operational complexity.

So the question remains: is it still worth launching?

Should You Still Launch in 2026?

Yes. But with method, structure, and clear eyes.

The marketplace market has never been more demanding. Saturated with expensive proofs of concept, unfinished projects, and invisible platforms, it no longer rewards early movers. It rewards solid operators.

The marketplaces succeeding in 2025 share one thing in common: they are focused, robust, and profitable. Their onboarding is industrialised, their service levels compete with retail benchmarks, their customer journeys are frictionless, and their ROI is measurable within 12 to 18 months.

Building a marketplace is no longer an innovation bet. It's a rational business decision, sitting at the intersection of commerce, technology, logistics, legal, and marketing.

The conditions for success are now well understood:

  • A clear vision of the platform's role in the business
  • Strong alignment between IT, senior leadership, and commercial teams
  • Rigorous execution across service, compliance, and quality
  • Performance-driven management focused on viability, not just growth

Those who succeed will not treat the marketplace as a "digital project". They will treat it as a critical component of their business model.
