The challenge
What high-stakes problem had to be solved?
The business context, constraints, and risk surface that shaped every decision.
Rennzone needed a Porsche-only marketplace that felt built for its community. A generic template would not do: the client wanted a fully custom Sharetribe build.
The platform had to support listings, payments and content in one place, stay fast and secure, and be found in search for Porsche-specific queries. GenAILabs delivered the custom design and build, security hardening, performance optimisation, SEO and GEO, then maintained it for three months after launch.
