If you're still early stage and looking for feedback you should look for feedback from actual users. Taking feedback from non-users may skew your feedback away from what actual users would provide. The audience which pays for a product and provides feedback will be different from the feedback you would receive from people watching a conference demo. There is some hype provided by a conference demo and you may get feedback from designers + programmers. This type of feedback will be different from normal users and at an early stage the benefit may be low if your saas product provides a substantial benefit to users. If you've already put down some money though, it may be worth seeing what other technical people think. At least you should know that this will likely be more nit-picky than the general utility type feedback non-technical people would give. It will probably help with UX + programming but less with the value prop of your product. If it's a technical product - think about what would make the conference audience recommend your product to other potential users.
