GTM Positioning Strategist for B2B SaaS Platform

We are building a B2B deal and documentation management platform for business sales, acquisitions, IP/asset deals and other complex transactions. The product is already designed and in production built on React and Supabase. We now need an experienced GTM positioning strategist to prepare it for real users and investors. Your role is to review the current product flows and value proposition, help choose a clear first niche such as business brokers or small M&A firms, define our positioning and messaging, create a simple 90 day go to market plan, suggest landing page structure and key copy points, and give feedback on investor partner readiness. Must have proven B2B SaaS experience ideally in legal tech deal rooms or project management. Please share 2-3 examples of SaaS or B2B products you have helped position or launch.
