You're In Business

SourceTank is a legitimate corporate venture by B. Braun (Werk_39) aiming to digitalize surgical instrument sourcing. While the project addresses a genuine B2B supply chain problem with backing from a major industry player, the submission itself contains highly inaccurate claims (e.g., 'everyone' as audience, 'most people' as users) and confusing metrics ('marketcap 500000'). The score reflects the verified utility of the underlying business, heavily penalized by the poor quality of evidence and unrealistic traction claims provided in the input.
