"We've got early traction" = Our investors has made sure their other portfolio companies use our product.

Would you rather work for a company where the investors can't even convince their portfolio companies to use the product? Sure I get the humor. Maybe a solution would be to actually name one of the (hopefully big/famous) companies that use the product, instead of being vague. "Some great places have employed our solution! But we can't reveal any of their names!" Um. Yeah.
