Full-Stack dev looking to build a niche downmarket SAAS

As the title says, I'm looking for a partner that either wants to help me build or a person that can help with product, market analysis and maketing . I'm open minded and look forward to hearing people's ideas .

In case your're wondering, my dev buzz words for building this project include react, react-native, graph-ql, node, azure postgres and prisma : )

Cheers
