Certified Problem Solver

B2B Stack is a verifiable, market-leading platform in Brazil, often described as the 'Brazilian G2'. Established in 2017 and acquired in 2025, it demonstrates strong real-world utility and traction with over 1 million monthly visits and significant influence on software sales (R$ 30M+ annually). However, the submission quality was extremely poor ('most people have used my product'), failing to accurately reflect the project's actual success. The score is bolstered by external verification of its dominance in the LATAM market but penalized for the lack of effort in the submission data.
