Custom Marketplace App for Brand-Creator Collaboration

Custom Marketplace App for Brand-Creator Collaboration

A web and mobile UGC marketplace that connects brands with creators, managing the full collaboration lifecycle from campaign creation and creator discovery to watermarked submissions, revisions, and escrow-backed payouts through a token-based economy.

Custom Marketplace App for Brand-Creator Collaboration

Project Overview

Brands struggle to source and manage creators for authentic content, while creators need structured opportunities and reliable payouts. Through two-sided marketplace development, Ditstek built a brand-creator collaboration platform that manages the entire lifecycle, from campaign creation and creator discovery to content submission, revision tracking, and automated payments. Unlike a typical influencer marketing platform, it prioritizes content quality over follower counts. Brands manage campaigns at scale from a web dashboard, creators work from a mobile-first app, and a token-based economy, real-time chat, and automated watermarking remove the friction of traditional content marketing.

Business Challenges We Addressed

Brands faced fragmented workflows, creator inconsistencies, and payment risks while trying to scale UGC collaborations. CreatorConnect addressed these core inefficiencies with a secure, automated, and scalable solution.

  • Limited Audit and Change History

    Limited Audit and Change History

    The initial database design lacked detailed change history, rollback capabilities, and field-level auditing, limiting visibility into system events across a marketplace handling payments and content.

  • Incomplete GDPR Compliance

    Incomplete GDPR Compliance

    Without automated data retention policies, data export tools, or consent auditing, the platform's GDPR compliance was incomplete, exposing the business to serious regulatory and legal risk.

  • High Media Storage Costs

    High Media Storage Costs

    Hosting high volumes of video and photos up to 4K resolution, for both public creator portfolios and private brand submissions, threatened to push infrastructure costs beyond profitability.

  • Margin Pressure from Token Discounts

    Margin Pressure from Token Discounts

    Discounted, higher-volume credit packs purchased by brands added further margin pressure, making cost control across storage, processing, and payouts critical to the platform's long-term profitability.

  • Risk of Leaking System Information

    Risk of Leaking System Information

    Misconfigured exception filters risked exposing sensitive system information in error responses, creating a security gap that attackers could use to learn how the platform worked internally.

  • Injection Attack Exposure

    Injection Attack Exposure

    Validation pipe failures opened the door to injection attacks, putting user data, payment records, and campaign content at risk across a platform built on trust between parties.

  • Fragile Shipping Dependencies

    Fragile Shipping Dependencies

    Relying on carrier APIs like FedEx meant any API failure or unsupported courier could break the strict 7-day content delivery timers that campaigns depended on.

  • Creator IP Protection

    Creator IP Protection

    Creators needed their work protected during brand review, since unrestricted access to submitted content would let brands use deliverables without approving or paying for them.

  • Unreliable Creator Payouts

    Unreliable Creator Payouts

    The business needed a way to guarantee creators were paid reliably, even if a brand became unresponsive or abandoned the platform in the middle of a campaign.

How We Architected the Solution

As a custom marketplace app development company, Ditstek designed a scalable, secure architecture with cost-controlled media storage, escrow-based payments, and built-in IP protection, so brands and creators can collaborate with confidence.

Scalable Modular Monolith

Scalable Modular Monolith

For this marketplace app development, a Modular Monolith built with Domain-Driven Design runs as one microservice-ready unit and scales horizontally through stateless Redis-backed services and PostgreSQL read replicas.

Retention Policy with Soft-Archive

Retention Policy with Soft-Archive

A 6-month content retention policy controls storage costs, while a soft-archive function removes completed campaigns from the active interface without deleting payment or audit records.

Carrier-Agnostic Shipping Workflow

Carrier-Agnostic Shipping Workflow

Brands ship products with any courier and enter tracking details manually, and the 7-day creation timer starts only after the creator confirms receipt of the product.

Escrow with Watermarked Previews

Escrow with Watermarked Previews

Brands review automatically watermarked previews of every submission, protecting creator work. Once the brand approves, the watermark is removed and the escrowed payment is released instantly.

48-Hour Payment Guarantee

48-Hour Payment Guarantee

If a brand takes no action for 48 hours after the final revision round, the system auto-approves the content and triggers the creator's payout automatically.

Resilience and Security Hardening

Resilience and Security Hardening

Database retries, Stripe webhook retries, CDN fallbacks, and queued SendGrid emails keep services running, while strict TypeScript typing and optimized Prisma queries eliminate injection risks.

End-to-End Marketplace Infrastructure

Through creator marketplace development across web and mobile, the platform covers every step of a UGC campaign, from secure sign-up and campaign setup to discovery, submissions, revisions, payments, and moderation.

Role-Based Access & Authentication

Role-Based Access & Authentication

Stateless JWT sessions with refresh token rotation, optional OTP two-factor authentication, device fingerprinting, and strict RBAC give Admins, Brands, and Creators secure, role-appropriate platform access.

Campaign Management Wizard

Campaign Management Wizard

A multi-step flow lets brands set objectives, deliverable types, targeting filters, and budgets, with options to save drafts, clone templates, and pause campaign discoverability at any time.

Creator Discovery & Proposals

Creator Discovery & Proposals

Brands filter the creator marketplace to invite creators directly, while creators browse active campaigns and submit pitches of up to 5,000 characters, with duplicate applications blocked automatically.

Token-Based Wallet Economy

Token-Based Wallet Economy

Brands buy credit packages through Stripe to fund campaigns. Tokens stay in escrow during active jobs and convert automatically into creator payouts and platform commission on approval.

Watermarked Content Submission

Watermarked Content Submission

Creators upload up to 10 high-resolution MP4, MOV, HEIC, or PNG files per submission, and FFmpeg applies a proprietary watermark that is removed only after brand approval.

Revisions & Contract Extensions

Revisions & Contract Extensions

Brands get up to two revision rounds, with 7-day timers enforced through BullMQ jobs. After approval, they can request extra deliverables at the original credit rate.

Real-Time Chat & Auto-Moderation

Real-Time Chat & Auto-Moderation

Socket.IO messaging scoped to active campaigns supports file sharing, while auto-moderation blocks off-platform contact attempts, such as shared Instagram handles, and flags violations to admins.

Multi-Channel Notifications

Multi-Channel Notifications

Firebase Cloud Messaging, SendGrid, and WebSocket in-app alerts keep brands and creators informed about campaign deadlines, revision requests, and payment events across mobile, email, and web.

Admin Moderation, Disputes & Ratings

Admin Moderation, Disputes & Ratings

Admins verify creator KYC, manage support tickets, issue strikes or bans, refund credits, and track KPIs in GA4, while mutual brand-creator ratings feed admin-only reputation scores.
