03 — Research & Insights

Key Insights

Understanding the barriers that prevent global trade from scaling required deep user research across buyer and seller personas.

1

Trust is the primary barrier. Users hesitate to transact without verified identity and payment protection. Trust is not a feature—it's the product.

2

Negotiation is unstructured. Deals were happening through free-form chat — leading to confusion, misalignment, and high drop-off rates.

3

No standardized transaction lifecycle. Every trade followed a different path, making tracking, reporting, and dispute resolution nearly impossible.

4

Post-payment uncertainty. Buyers feared fraud or non-delivery. Without escrow protection, large transactions felt too risky to complete online.

User Interviews
"I would trust this platform more if I knew the seller was verified and my payment was protected until delivery." — Global Buyer
Workflow Audits
"Every negotiation is different. I never know what the final deal will look like until the last message." — B2B Seller
Competitive Analysis
Existing B2B platforms lacked escrow, had weak KYC flows, and provided no structured deal stage visibility for either party.
04 — Design Goals

✓

Reduce friction in buyer–seller negotiation

✓

Introduce secure escrow-based transactions

Provide transparent shipment tracking and visibility

Core Problem
"Cross-border B2B trade lacked the trust infrastructure needed to convert discovery into completed deals at scale."

Unstructured chat-based trade

No trust verification

High fraud risk and payment disputes

✅ After

Verified marketplace (KYC/KYB)

Structured deal lifecycle system

Escrow-secured payments

End-to-end shipment tracking

Transparent transaction history

09 — Key Design Decisions

Principles Behind the Platform

1

Deal-Based System (Not Chat-Based)

Converted communication into structured transactions — every message could become a formal offer, counteroffer, or agreed term.

2

Trust Layer First

KYC/KYB became mandatory before marketplace access — verification is the gateway, not an afterthought.

3

Escrow Integration

Eliminated payment fraud risk in cross-border trade. Sellers fulfill; buyers confirm; admin releases. Three-party protection.

4

Lifecycle-Driven UX

Every trade follows a clear state machine — Interest → Negotiation → Deal → Payment → Shipment → Completion. No ambiguity.

10 — Challenges & Trade-offs

Hard Design Problems

🌍

Designing trust in a high-risk global marketplace. Users from different countries had varying levels of digital trust. Verification flows had to feel secure without being so complex that they caused drop-offs.

⚖️

Balancing flexibility with structure. Negotiation needed to be open enough for complex deals, but structured enough to convert conversations into binding agreements.

📦

Handling disputes and delivery uncertainty. Designing the dispute resolution flow required accounting for partial deliveries, quality issues, and delays without creating a legal liability problem.

🎭

Multi-role complexity. The same user might be both a buyer and a seller. The platform had to support role switching without creating confusion or data leakage between contexts.

11 — What I Learned

Key Takeaways

01

In marketplaces, trust is the core product — every design decision either builds or erodes it.

02

UX must define system behavior, not just interfaces — lifecycle states matter as much as screens.

03

Structured workflows dramatically improve conversion — removing ambiguity from negotiation closes deals.

04

Escrow + verification systems increase marketplace liquidity — trust unlocks volume.

12 — Quick Portfolio Summary

In One Paragraph
