People always want to believe they were backdoored when they loose a deal. It is possible you got beat or the company had the file already or any other number of things that results in losing a deal. Does backdooring happen, absolutely. Do I think a company as big as fundbox would risk their reputation to steel a file when they have so much to lose if they did and got caught absolutely not. The amount of money they would make on the file is pennies compared to the risk they are taking if they get caught. Funders are not always wrong or at fault and if brokers are allowed to just throw allegations around on this forum everytime they lose a deal then this forum will become a joke.
