Has 37s indicated how the billings will transfer? If by default, after the sale, users have to opt-in and provide their billing information again, there will be a substantial loss of customers, well beyond typical churn.<p>Additionally, if I were interested in purchasing Sortfolio, I'd want a clear picture of their customer acquisition practices. If most customers are being acquired through the 37s website and/or branding, you cannot count on continued revenue streams. If customers are being acquired by channels that don't rely on 37s, I'd be much more comfortable with it.
