Overview
TransUnion API Marketplace is a one stop solution for our B2B customers to discover, test, integrate and start consuming our TransUnion API services.
Customer Pain Point
API Platform at TransUnion existed as a basic tech initiative with minimal adoption. Documentation was fragmented (PDFs, emails), onboarding was manual, and customers were still relying on legacy integrations.
Product Goal
I was responsible for transforming this into a scalable developer marketplace, driving both adoption and monetization, while aligning internal product teams and external customers.
Approach
Improved developer experience: Standardized API documentation (use cases, error codes, data dictionaries) and launched self-serve onboarding, reducing dependency on manual support
Aligned internal teams: Drove adoption across product teams and used a cross-functional hackathon to generate use cases and secure leadership buy-in
Drove customer adoption: Created pull-based incentives (exclusive API-first products) and pivoted GTM to CIO/CTO engagement, positioning on tech benefits (security, scalability)
Built monetization engine: Introduced tiered pricing + platform premiums (X%), linking pricing to clear value
Impact
Repositioned the platform from a technical layer to a strategic product platform
Enabled large-scale partner adoption and high transaction volumes
Generated significant revenue through structured monetization
Established the platform as a key growth driver for the business
