New B2B marketplaces target construction, equipment and data center sourcing
Q1 2026 saw a wave of vertical B2B marketplaces launch across construction materials (MatBook, Kojo, ProjectMark), equipment rental (DOZR, Kwipped, EquipmentShare), and data center infrastructure (Start Campus Marketplace, HyperScale Hub) — three sectors collectively representing hundreds of billions in annual procurement that has historically been phone-and-spreadsheet driven. These platforms are introducing real-time pricing transparency, supplier comparison, and centralized sourcing where none existed, directly threatening traditional distributor margins and local supplier relationships. For sellers with catalogs touching industrial supplies, MRO, construction inputs, or tech infrastructure components on Amazon Business or Walmart Business, this signals accelerating channel fragmentation. Early-stage now, but these platforms are structurally designed to bypass the intermediaries that currently capture 20-40% gross margins in these categories.
The non-obvious play here is on Amazon Business, where sellers in construction, industrial, and infrastructure-adjacent categories currently benefit from procurement inertia — buyers use Amazon because there's no better vertical alternative. That moat is actively being eroded.
As MatBook and DOZR achieve critical supplier mass, Amazon Business GMV in these categories will face price compression first, then volume loss, mirroring what happened to generalist B2B distributors when Amazon entered MRO in 2017-2019.
A $10M/year Amazon Business seller in industrial or construction supplies should immediately audit which SKUs have zero vertical marketplace competition today versus which are already listed on DOZR or Kojo — those are your 90-day warning signals.
Start building direct supplier relationships and exclusive SKU arrangements now, before these platforms commoditize your catalog and collapse your 30-40% margins into 10-15% marketplace-mediated thin margins.
This is the 2026 manifestation of the same vertical marketplace unbundling that hollowed out generalist B2B distribution in manufacturing and healthcare over the past decade — specialized platforms winning category by category until the generalist channel loses pricing power entirely.
For the broader marketplace landscape, this accelerates the bifurcation between horizontal platforms like Amazon Business (volume, convenience, breadth) and vertical platforms (price transparency, procurement workflow integration, category depth), forcing sellers to choose which game they're playing and optimize accordingly.
Operators who treat this as an 'early stage, not relevant yet' story will find themselves in 2027 explaining why their Amazon Business conversion rates dropped 30% in construction and infrastructure categories — the time to reposition is before the volume shifts, not after.
Pull your Amazon Business Sales report filtered by NAICS/industry category and identify any SKUs in construction materials, equipment accessories, or data center infrastructure — if those SKUs account for more than 15% of your B2B revenue, initiate a competitive listing audit on DOZR.com and Kojo this week to see if your suppliers are already onboarded there, which signals imminent price transparency pressure on your Amazon listings.
This week, contact your top 3 construction or industrial suppliers and negotiate exclusivity clauses or private-label arrangements on your highest-velocity B2B SKUs — the window to lock in supplier exclusivity before these vertical marketplaces aggregate them into comparison engines is measured in months, not years, and once pricing becomes transparent across platforms your margin compression is structural and irreversible.
In the next 30-60 days, build or expand your Amazon Business punch-out or EDI integration capabilities — as procurement teams at construction and data center companies adopt these new vertical platforms, they will demand API-level integrations and net-terms from all vendors, and sellers who can't support purchase order workflows and ERP connectivity will be delisted from approved vendor lists regardless of price competitiveness.

Full Coverage
A new group of B2B marketplaces launched or expanded in the United States during the first quarter of 2026, targeting construction materials, equipment rental and data center infrastructure — three sectors where procurement has remained fragmented and offline.
Though many of the platforms are still in initial stages, their emergence reflects a broader push to digitize sourcing in heavy industry, where buyers are under pressure to manage rising costs, tight supply, and more complex project requirements. In construction materials, several newer marketplaces are aiming to bring greater transparency to sourcing.
MatBook has launched a digital marketplace focused on bulk materials such as aggregates and concrete inputs. It has put an emphasis on real-time pricing and supplier comparison. Kojo has historically focused on procurement software. It has expanded its capabilities to connect contractors more directly with suppliers through a centralized system.
Meanwhile, ProjectMark is developing a bid-based marketplace model that links contractors with suppliers for specific projects. These platforms are targeting a part of the market that still relies heavily on phone calls, spreadsheets and local relationships, with limited visibility into pricing or availability across regions.
New B2B marketplaces prioritize procurement In equipment rental, marketplace models are gaining traction as contractors shift toward renting rather than owning equipment. Platforms such as DOZR and Kwipped are aggregating supply from multiple providers. That allows users to compare pricing, availability and delivery options through a single interface.
At the same time, EquipmentShare continues to expand its technology-enabled rental network. It’s combining fleet management, logistics and procurement tools in a hybrid model that overlaps with marketplace functionality.
The result is a more centralized approach to equipment sourcing, where access to inventory is increasingly managed through digital platforms rather than local relationships. A third area of marketplace development is emerging around data center infrastructure, driven by rapid growth in artificial intelligence (AI) and cloud computing.
New platforms are focusing on sourcing specialized components such as power systems, cooling equipment and modular infrastructure. Early entrants include Start Campus Marketplace, which is designed to connect developers with suppliers, and HyperScale Hub, an early-stage platform focused on high-density computer infrastructure.
Platforms such as DCKAP Integrator Marketplace are also expanding into supplier network models that support more complex sourcing and integration requirements. Together, these developments point to the early formation of a digital sourcing layer in sectors that have historically resisted standardization.
For B2B sellers, the rise of these marketplaces presents both competitive pressure and new opportunities. Marketplaces can aggregate demand and increase pricing transparency, potentially reducing the role of traditional intermediaries.
At the same time, they offer distributors new channels to reach customers without building standard-line ecommerce platforms. As these early-stage B2B marketplaces scale, they are likely to place greater emphasis on real-time inventory data, consistent product information and faster quoting — procurement areas where many distributors are still investing.
