U1CORE

UX/UI Design & Development Agency | Marketplace, SaaS & Fintech Platform Specialists

At U1CORE, we design and build two-sided and multi-sided platforms — systems architected around real buyer-seller, client-provider, and vendor-admin behavior. We turn complex multi-sided logic into experiences people actually understand and trust.

WHAT WE DO

🔹 B2B Marketplace Design & Development
Account-based pricing, approval workflows, multi-tier buyer hierarchies, RFQ and quote-to-order flows, ERP integrations. Built for procurement reality, not retail logic.

🔹 Service & Gig Marketplace Design
Two-sided platforms connecting providers and clients — booking flows, trust signals, dispute resolution, review systems, commission structures, Stripe Connect payouts.

🔹 Vendor Onboarding & Seller Activation
Progressive flows that move vendors from sign-up to first transaction — the metric that decides whether your marketplace lives or dies.

🔹 Two-Audience Landing Pages
Pages built to grow supply and demand at once, with separate value propositions and conversion paths for each side.

🔹 Wireframing, Prototyping & Marketplace Architecture
Full vendor, buyer, and admin flow prototypes — so marketplace logic and role-based permissions get validated before a single line of code is written.

WHY U1CORE
A marketplace isn't eCommerce with an extra page. It's a multi-sided system: cold start, vendor activation, dispute resolution, split payments, dynamic commissions, network effects. Our SaaS and fintech background means complex dashboards and payment flows are everyday work — not edge cases.
