Just because you hide a software consulting shop behind an app doesn't mean you can change the fundamental difficulties with software consulting. I wish Gigster luck, but ultimately this approach isn't much different from what many offshore dev shops do today. I can get a quote in under an hour from a half dozen places today; but it doesn't mean it will be accurate or what I want.
This. Nothing has changed from going to upwork or freelancer or whatever, except rather than many bidders to chose from you just have one.
