Off-the-shelf marketplace platforms are built for simple supply-meets-demand transactions. If your matching logic, commission structure, trust mechanisms, or multi-sided workflows are more complex than that, the platform breaks down, or you pay for years of custom development on top of it.
We build custom two-sided and multi-sided marketplace platforms from scratch. Matching, payments, trust and safety, and the operational tools your team needs to run the marketplace.
Custom marketplace built for your specific matching logic and commission structure
Payments, escrow, and split payouts for all major payment providers
Trust and safety systems including reviews, verification, and dispute resolution
100+ products shipped including platforms with complex multi-party transactions

The frontend is the easy part. The hard part is the payment architecture, the matching logic, the trust and safety system, and the admin tools your team needs to operate the platform.
Most marketplace failures aren't product failures, they're architecture failures. The payment split doesn't work for the commission structure. The matching logic can't be configured. The admin can't manage disputes without calling engineering. These aren't edge cases; they're the core product.

Why us
The engineers who assess your problem also build the solution. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.
We scope the work, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record across AI, SaaS, mobile, automation, and enterprise platforms across healthcare, fintech, logistics, and hospitality.
GDPR, HIPAA, SOC 2 — compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped HIPAA-compliant systems for US healthcare clients and GDPR-compliant products for European markets.
Matching logic, payment structure, trust requirements. We'll design it and give you a fixed cost.
Process
We start by understanding your marketplace model before writing a line of code. Two-sided or multi-sided? Instant booking or request-to-accept? Fixed commission or variable? What does trust look like for your transaction type? The payment architecture is designed in this phase, it's where most marketplace complexity lives, and it can't be refactored cheaply later.
Market model documentation: participant types, transaction flow, commission structure
Payment architecture design: split payment logic, escrow rules, payout schedule
Trust and safety requirements: verification depth, review system, dispute rules
Fixed-cost scope for the first phase with milestone delivery dates
We build the listing, discovery, and transactional core in 2-week sprints. Search and filtering built for your matching model. Booking or request flows designed for your transaction type. Profile and listing management for both sides of the market. Every sprint delivers working software both sides can use and give feedback on.

Listing creation, search, and discovery built for your matching logic
Booking or request-quote-accept flow designed for your transaction model
Profile management and verification workflow for suppliers or providers
We integrate Stripe Connect (or your required payment provider) with split payment logic, escrow conditions, and payout scheduling that matches your commission model. Reviews and ratings, identity verification, and dispute resolution workflows are built alongside payments, not after. Trust is the product; it can't be deferred.

Escrow and conditional release logic for service-based transactions
Identity verification integration (Onfido, Stripe Identity, or document upload)
Review and rating system with anti-manipulation safeguards
We build the full admin panel your operations team needs to run the marketplace without engineering involvement. User management, listing approval, transaction monitoring, dispute resolution, commission configuration, payout management, and fraud flagging. The admin requirements are scoped in detail during discovery, they're often as complex as the user-facing product.

Fraud flagging rules and reporting for risk management
We deploy to production and support the go-live strategy, starting with seeded supply, a restricted geography, or a single vertical depending on your cold-start approach. Post-launch, we add the growth tooling your marketplace needs: referral mechanics, promotional pricing tools, and the analytics your team uses to measure supply-demand balance.

We build two-sided marketplaces (buyers and sellers), service marketplaces (clients and service providers), B2B marketplaces (businesses buying from businesses), rental and sharing economy platforms, and multi-sided platforms with more than two participant types. Use cases include: freelance and talent marketplaces, product and inventory marketplaces, booking and appointment platforms, lead generation and referral marketplaces, and industry-specific procurement platforms. The common thread is a platform that connects multiple parties and manages the transaction between them.
Marketplace payments are more complex than standard e-commerce, you need to split payments between the platform and the seller, handle escrow for service-based transactions, manage payouts on a schedule, and deal with refunds and disputes across multiple parties. We integrate with Stripe Connect for most marketplace payment flows (it's the best-supported infrastructure for this use case). For specific geographies or requirements, we also work with Adyen, Mangopay, and regional payment providers. We build payout schedules, commission calculations, and tax reporting into the payment layer.
Every marketplace faces the supply-demand cold start problem, sellers won't join without buyers, and buyers won't engage without sellers. We address this in the product design phase. Common approaches include starting with supply-side only (building the seller/provider experience first and seeding with manually sourced providers), geo-restriction (launching in one city or vertical before expanding), and aggregation (starting as a directory before adding transaction capability). We design the marketplace sequencing into the launch strategy, not just the product.
Every marketplace we build includes a full admin panel for the operations team. This covers user management, listing approval workflows, transaction monitoring, dispute resolution tools, commission configuration, payout management, fraud flagging, and reporting. The operations team needs to be able to manage the marketplace without engineering involvement for day-to-day tasks. We scope the admin requirements in detail during discovery because they're often as complex as the user-facing product.
Trust is the core product of a marketplace, without it, neither side transacts. We build trust and safety systems including identity verification (integrated with Onfido, Stripe Identity, or document upload + manual review), reviews and ratings with anti-manipulation safeguards, seller/provider verification workflows, escrow and conditional release for high-value transactions, dispute resolution workflows, and fraud detection rules. The specific mechanisms depend on your marketplace type and the risk profile of transactions.
A focused marketplace MVP, core matching, listings, payments, and basic admin, typically runs $60,000--$120,000. Full-featured marketplace platforms with advanced matching, complex payment flows, trust and safety systems, and a complete admin panel run $120,000--$250,000 or more depending on complexity. We always scope before pricing. For marketplaces, the most important scoping question is the payment architecture, that's where complexity lives.
