Ask HN: Inverse of Product Hunt?

Does the 'inverse' of Product Hunt exist, where posts are business problems solvable by software and upvotes are money users are willing pay for a solution? A rough equivalent could be a one-to-one relationship (1 biz to one dev) as established by a freelancing marketplace (e.g. odesk, elance, etc.), but I'm thinking along the lines of a many-to-one (many businesses to one dev).
