B2B SaaS founders launching products on a budget under $150,000 face a specific problem: they cannot afford large agency retainers or macro-influencer sponsorships, yet they need authentic distribution to reach their first hundred or thousand paying customers. Cold ads are expensive and getting more so, and founder-led content alone does not scale. Stack Influence Micro-Creator Matching for SaaS Product Launches solves this by operating as a two-sided marketplace that matches niche micro-creators on LinkedIn and YouTube with B2B SaaS companies running product launch campaigns. The core solution is authentic product review campaigns from creators who already have the trust of the exact buyer persona a SaaS founder is chasing, with every placement tracked by attribution links so founders can see which creator drove which signup or trial. The MVP is a matching layer: a curated roster of vetted B2B micro-creators, a brief-submission flow for founders, and attribution links baked into every deliverable so ROI is visible from day one. Revenue comes from taking a percentage cut of each campaign booked plus a possible subscription for founders who run recurring launch motions. Go-to-market starts inside the communities where this exact playbook is already being discussed, the YouTube channels teaching creator-led GTM and how to get your first 100 SaaS customers without ads. Growth loops form naturally: creators who earn on the platform recruit other creators, founders who see attributed conversions come back for the next launch and refer peers, and case studies from successful campaigns become the content that seeds the next cohort.
