Marketplaces are operating models, not features.
Most marketplace initiatives fail before they reach their second year. Not because of poor platform selection, but because the underlying business model, seller onboarding strategy, and operational infrastructure were not designed to scale. McFadyen has launched and operated marketplaces across B2B distribution, manufacturing, electrification, and consumer categories. We start with the operating model. The platform comes after.

The Marketplace Challenge

Why Most Marketplaces Fail to Scale

Many marketplace initiatives stall after launch. Not because of poor platform selection, but because the underlying business model, seller strategy, and operational infrastructure weren't designed for scale.

Complex seller onboarding and catalog management without the right tooling

Fragmented pricing, contracts, and catalog governance across multiple sellers

Disconnected fulfillment and order management across a multi-party network

Poor buyer and seller experience that drives abandonment instead of adoption

Limited governance, compliance controls, and operational visibility

Without the right strategy and architecture from the start, marketplaces become expensive experiments instead of scalable revenue engines.

    Marketplace Foundations

    Our Point of View

    Marketplaces Are Operating Models,
    Not Features

    Successful marketplaces require a shift in how organizations think about commerce. They introduce new roles, responsibilities, incentives, and technical dependencies across the business, none of which come pre-configured in a platform

    McFadyen approaches marketplace enablement as an operating model transformation, aligning business strategy, platform architecture, and operational processes to support multi-party commerce at scale. We get the business model right before we select the technology. That is why our engagements always begin with business model design, not platform demos. By the time we recommend Mirakl, commercetools, or a custom API-first build, we already know what the marketplace needs to do for the business, who the sellers are, and how buyers will actually use it.

    Where AI Fits in Marketplaces

    Using Intelligence to Reduce Friction and Improve Scale

    AI enhances marketplaces when applied to operational and decision challenges — not as surface-level features. Applied responsibly, AI supports:

    Seller onboarding and catalog normalization — faster time-to-live, higher data quality

    Intelligent product discovery across sellers — unified search that surfaces the right product regardless of source

    Pricing and demand insights — margin optimization and competitive positioning across the seller network

    Fraud detection and anomaly identification — protect buyers, sellers, and the platform operator

    Marketplace performance optimization — AI-assisted merchandising, assortment, and seller scoring
    AI in Practice
    AI-Ready Marketplace Architecture
    We design marketplace architecture for AI-powered discovery from the start — structured product data, MCP-compatible seller APIs, and inventory signals that procurement AI systems can read and transact with. Your marketplace becomes discoverable not just to human buyers, but to the AI tools they're increasingly using to source.
    AI in Practice
    Agentic Buying and Marketplace Discoverability
    AI procurement tools are already sourcing from marketplaces. The marketplaces that win are the ones with clean structured data, reliable pricing APIs, and seller catalogs that AI systems can parse without human intervention. We build for that from day one.
